You finally got the bug and went out and bought a sleek widescreen HDTV. You got turned on by the jaw-dropping clarity at the store and the promise that you’d get that same thrill at /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’>, only to discover that for some reason the picture is not the same.
You’ve certainly seen the commercial where a customer calls the store to complain that he’s or she is not getting the sound expected, and by the time the customer service guy reaches the door, the windows shatter from the blast of the sound. Something to do with the connections. Well the same applies to HDTV.
In order to view an HDTV image on your screen, you must make sure that your cables are properly connected. In standard definition programming, I’m sure you’ve noticed that the cable connectors (also known as S-Video cable) are red, yellow, and white.
High Definition programming uses cables with connectors that are red, blue, and green, or DVI cable, or the premium choice HDMI, which offers the highest quality and information or data between your receiver and TV. But that’s not all.
The programming must also be in high definition, which means that you need to subscribe for HDTV programming through or from your local cable company or satellite TV provider. Normally, you’ll rent the receiver box capable of accepting HDTV signals and usually will pay a little more for High Definition channels.
However, you can also receive Free over-the-air HDTV signals depending if your TV has a built-in ATSC tuner. Check the specs, and if it does, all you need is an antenna from your local store.
Did you consider a Blu-Ray? Since you’re ready to invest in an HDTV, capable of displaying up to 1080 lines of resolution, you really cannot do without blue-violet laser technology rather than red laser technology. Simply put, the two combined will deliver true HD clarity, better sound, and interactive media.
For the kids and adults too, let’s not forget the games and /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> movies. Your HDTV was not just made for TV, movies and sports entertainment. Have you forgotten games and /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> movies. Most have no idea how a game with surround sound and special effects can feel.The Xbox for one delivers HD content with 1080i and multi-channel surround sound. It’s totally awesome!
High-definition gaming was born with Microsoft’s Xbox 360, and if you want to take advantage of everything HD gaming has to offer, you have no other choice but to own a television with a native minimum resolution of 720p or 1080i. You’ll get a more detailed picture in widescreen format.
What’s the Blu-Ray you ask? It is to me the ultimate in wireless systems, manufactured by Sony. It isn’t cheap but what’s the point of being quality on one end and non-quality on the other end.
The important thing to remember in all of this as you make your choices for different equipment, is to keep in mind that, connectivity wise they must be compatible to each other. Example; there’s no point in trying to connect HD equipment to non-HD equipment.
In all electronics technology, you’re only cheating yourself if you’re not making use of all the advantages that any equipment has to offer. After all, that’s why you paid the big money for, so why not use it. You’ll then appreciate your piece much, much more, and won’t feel so bad about the money.

Ipods are the next wave in portable listening devices. Once, people listened to music on battery powered portable radios. Then came the convenience of choosing your own music by carrying about the bulky Walkmans that played cassette tapes. Then those Walkmans slimmed down to something a little more portable. Then CD players became the must-have item. Those, too, started out rather bulky but then became small and portable.
Today, the must have music device are Ipods. They hold a small hard disk drive inside of them that stores many songs (sometimes hundreds). Depending on the unit that you own, it likely has many of the popular features of most music playing devices, including play, random, and repeat. Many Ipods are coming with additional features now, too, that include photos, video, cameras, and cell phones.
Of course owning an Ipod means that you HAVE the music in the palm of your hand (after all, Ipods are extremely light and portable) but now you need to get it from your Ipod to your ears. Ipods can store high quality music so you shouldn’t be tempted to save your money by spending a dollar on cheap headphones at the dollar store. Instead, if you like the music you’re listening to, you should be willing to spend a little extra to actually hear the music and enjoy it. You need Ipod headphones.
Makers of Ipod headphones and other portable listening devices include Maxell, Sennheiser, Shure, Sony, Phillips, and Koss. Each of these companies, and the many others that make Ipod headphones, offer a variety of equipment: it varies in comfort level, affordability, durability, and ability to accurately transmit the sound. As well, there are other features you’ll want to consider. Let’s look at comfort level:
Ipod headphones are most frequently the earbud style, meaning they are small, semi-circular speakers that fit right into the end of your ear canal and point the speaker into your ear canal. They can produce a fairly good sound, however, if the earbuds are too big for your ears, you will experience discomfort. Supra-aural headphones (which are the second most common type for portable listening devices) are simply speakers surrounded by pads that just sit on your ears, usually with a band that goes over your head. There are other kinds, as well, include canalbuds (which are more comfortable and go right into your ear canal) as well as circumaural which don’t just sit on your ears but encompass them entirely - like you’ve seen professional musicians listening to while they record.
Canalbuds are extremely comfortable because they are encased in a soft housing, unlike earbuds which often tend to be mass produced in a plastic housing. Supra-aural Ipod headphones can be comfortable but they can mess up your hair, which isn’t nice. Circumaural headphones are great for transmitting sound but they can be heavy so if they are too tight, they’ll cause a headache. Comfort level is an important consideration when looking to buy Ipod headphones for your portable listening enjoyment.
For quality headphones from Shure, Koss, Sennheiser, Bose, AKG, Ultimate Ears, Ipod and MP3, Etymotic and others…go to wwwHeadphoneWareHouse.com. Whether you’re looking for canal earphones, earbuds, or noise cancelling headphones, Headphone Warehouse carries only the best in quality head phones

Every evening do you fight over the remote control? Do you wish that your television set had two separate screens? Would that stop separate room viewing? Will it rekindle your love life? If your answer is yes read on.
No I want to watch my show, screamed Mary.
But I want to watch my show, screamed Bill. This verbal battle can continue long into the night and can be followed by a few slaps or a trip to the emergency room. If you add a few beers or drugs who knows what the outcome will be.
Somebody will be the loser over this power struggle. This is not a simple fight over the TV remote control. This is also a power struggle, a control issue.
I hear more women say I would rather live alone. I will not have to give up the control of my remote control. I can watch what I want on television. When a man gets involved in my life the first part of my independence I lose is the remote control.
Wouldnt it be nice if we can purchase a television set that has two separate screens? That would stop some of this war over the remote controls. Snuggling and cuddling on the couch can be achieved. Peace throughout the home can be felt.
Maybe there are two television sets with two separate screens already on the market. Maybe we can just take two separate television sets and place them next to each other. By wearing a head set the noise from both television sets wont disturb your television viewing partner.

A digital camera is an electronic device used to capture and store photographs electronically instead of using photographic film like conventional cameras. It uses a digital sensor to capture the light instead of traditional film. The LCD on the back of a digital camera is your on screen guide to altering the settings before a shoot and reviewing the results afterwards.
The big advantage of digital cameras is that, unlike film, you can reuse the storage media over and over again at no extra cost.
Bearing this in mind you can quickly delete unwanted images and take more photographs as you go along. Also making photos is both inexpensive and fast because there is no film processing needed for obtaining prints.
The range of digital cameras is immense, and provides an equally large span of capabilities and functionalities. The main tip for using digital cameras is don’t be afraid, read the manual and just experiment.
One of the main ways that manufacturers categorize their digital cameras is in terms of pixel count, ranging from low end consumer cameras around 3.1mp (mega pixels) up to 10mp or more in professional cameras. If you plan on printing 8 x 10-inch prints, a 5 megapixel digital camera is more than enough.
When you’ve had a digital camera for a long time, you’ll learn enough to experiment with your digital photos online. Almost any digital camera is capable of taking pictures for display on the internet, or for sending across the internet as email and uploading to online galleries such as Webshots and Flickr.
One thing to be aware of is how many many pictures the camera can take with one set of batteries. Can the batteries be recharged, can I use normal AAs or does it need a lithium battery with its own charger?

Once again, there is a technology format war looming on the horizon. Many people don’t remember the VHS - Betamax battle that broke out when video players were first introduced, making it possible for people to watch movies at home. This was a case of two non-compatible technologies, each of which was a format for taping full length feature films. Ultimately VHS won out, and the movie companies put out their products in that format - thus dooming Betamax and the product manufacturers that had adopted their technology, not to mention the thousands of consumers that had invested in Betamax players. We now find ourselves on the verge of creating a new set of sore losers.
Skirmishes over LCD versus plasma screen HD TV technology are ongoing, but that type of technology contest isn’t as acute because you can watch TV or a movie on either type of screen. Currently, you can also play every DVD available on any DVD player that is in production and on the market. The next generation of DVD players, however, is coming over the horizon in the form of two distinct and incompatible technologies.
Toshiba versus Sony
Toshiba has developed a proprietary technology dubbed high definition DVD (HDDVD) and to support their format has developed alliances with Microsoft and Universal Films, among others. The HDDVD disks will be available in 15GB and two sided, 30GB versions.
By way of comparison, the current DVDs have enough storage for two hours of standard definition (SD) images, while the one-sided 15 gigabyte HDDVD disk can store up to eight hours of high definition (HD) images. The difference between SD and HD is simply twice the number of pixel lines displayed on the screen in the HD format, thus providing a crisper picture. The increased capacity of these disks will also allow for interactive features such as screen-in-screen director’s discussion of movie scenes playing behind him that today’s standard DVDs cannot support.
In the other corner is the Blu-Ray technology developed by Sony, who has lined up support from Apple, Disney and 20th Century Fox. Both formats use blue laser technology, which has a shorter wavelength than red, allowing it to read the smaller digital data spots packed a lot more densely onto a standard-size disc. Blu-Ray disks are designed to carry up to 50GB of digital material, which may mean that Sony wins the compression competition.
The Early Rounds
Sony Pictures released the first six films on Blu-Ray disks in June of this year, and have released a few more since. Samsung has a Blu-Ray DVD player in the stores, while Sony’s hardware division has released a Blu-Ray compatible PC. Toshiba has its initial HDDVD player on the market and there are a limited number of titles available in the format, mostly re-releases of previous first-run features.
Sony clearly jumped out to an early lead, with support from Dell, HP, Mitsubishi and a number of other hardware manufacturers. In addition, Sony Pictures also owns Columbia and MGM, giving them an enormous library to work with. Sony will also fold its technology into the PlayStation 3 gaming machine, their proprietary product whose 2nd version rules the roost in the videogame market.
On the Toshiba side of the battlefield, proponents argue that the HDDVD disks will be cheaper to produce and that it will be comparatively easy for disk replicators to retrofit their equipment for production purposes. The HDDVD format also makes production of recordable DVDs much simpler than with the Blu-Ray design.
Further, an alliance with Microsoft will be a formidable edge in this battle, should it turn into a protracted conflict. Microsoft’s operating systems are going to be important cogs in the development of future home viewing systems, as the technology moves closer to merging the functions of computers and televisions. If movie downloads become a commercial success, PC compatibility will be critical for these disks.
The Consumer Issues
One of the reasons that Microsoft aligned with Toshiba’s technology is that HDDVD provides for mandatory managed copy. What that means is that unlike with today’s conventional DVDs, managed copy allows consumers to make legitimate copies of their HD movies and enjoy this content around the home or across their personal networks. Making this feature mandatory will ensure a consistent consumer experience across all next-generation DVD content.
Then there is the element of iHD, which is the concept of maximizing high definition video for transport across the internet. This is a specific set of video specs which the iHD.org, a group of tech and media companies, is pushing as a cross-platform standard.
The theory is that next-generation HD movies will provide a level of interactive experience well beyond that of today’s conventional DVDs. iHD technology is meant to provide a broad foundation to enable new interactivity with standards-based development tools and technologies.
The pitch for this standard is that it will provide consumers with enhanced content, navigation and functionality for HD films. The business reality is that Microsoft plans to implement iHD support in its Windows Vista operating system, which will not only be a significant step towards integrated video and computer systems but will make help drive adoption of the new Microsoft platform.
Duel to the Death Unlikely
There is some indication that all of these conflicting issues may ultimately force a compromise - some sort of merger or unification of the two technologies. Hardware manufacturers are hedging their bets, with the latest wrinkle being that Blu-Ray-aligned Hewlett Packard has requested that mandatory managed copy and the iHD standard be included in Blu-Ray’s feature set. Sony has agreed to include the managed copy feature, but said no to iHD.
The Betamax - VHS battle was a tussle over hardware with the movie companies playing a predominant role, one Sony lost. This time around, there is much more uncertainty about how the next generation of home video will roll out. How will the Web and the PC fit in? Will the movies be delivered via disk or via download? How will the film industry protect its content rights and how can the hardware companies maximize their role?
PCs have become a commodity. If a scenario arises where every household needs a new computer to match up with new video technology, the Dells and HPs of this world stand to win big. If competing technology keeps people from investing in either, every involved business will suffer. If the film and DVD houses have to produce two sets of content and two disks for every film, their margins will grow considerably thinner as well. The tech bloggers seem to be increasingly inclined to believe that unification of some sort is inevitable. The corporations with the most to lose are too smart not to insist on it.

Defining the best /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater system is a matter of personal choice. Does a system worth $250,000 offer better quality than one that cost just $3000 to put together? Probably, but how many people can afford to spend a quarter of a million dollars on /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> entertainment?
Take my case for example. I’m a /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater nut who loves nothing better than being engrossed in my favorite movies in the confines of my own /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’>. In my spare time it’s my relaxation. My /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater system which includes the basics such as a television, DVD and speakers as well a a few optional extras set me back about $6000. I love it! My two closest friends who happen to be my next door neighbors are also /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater nuts with rather deep pockets. Their interpretation of the best /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater system includes the best that Bang And Olufsen have to offer and they are happy to fork out a six figure sum to get the best quality. What’s my point? It’s personal choice!
Satisfying Your Budget
Setting a budget you can afford and then doing a little due diligence is your first step towards finding your best /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater system. Is your budget $3000? Do you realise that for this amount you can get yourself a very reliable and neat little system. A television, either plasma or LCD, a DVD player, speaker system and projection system plus accompanying cables for between $3-4000 is achievable. You simply need to spend a little time researching the options available.
The entry level /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater market is cut throat so bargains are there to be had. The majority of people searching for systems are usually looking at this end of the scale. Comparison shopping should be your number one priority. Spend some time checking out the various local stores. Don’t even consider making a decision until you’ve sniffed out each one. Once you’ve done this, then it’s time to get online. Why? Because this is where you will in all probability, find the best buys.
Home Theater Online
A search for best /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater systems will get you a myriad of results. Some sites are extensions of the major stores repeating many of the deals you checked out physically however, many aren’t and this gives you extra choice flexibility. Other sites offer any amount of information with some going the extra mile and offering mix’n'match alternatives or reviews on the best bang for your buck available. The message here is don’t be hasty and purchase the first television or DVD combination from the first salesperson you come across.
Personal choice is what it’s all about. The best /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater system on the market, taken literally, will set you back thousands upon thousands of dollars however, choose what’s best for you and your budget. Let me assure you, for just a few thousand dollars you can experience some pretty serious /new?tag=day2soft-20′title= ‘: Newly tagged products at Amazon.com’> theater pleasure!

When you start to look for your new television set you will be confused and you will be amazed. All the television companies try and capture the eyes of the buyers, it is natural and normal, but the differences in quality and the price will be pretty significant, and if you want to get out of the shop with some money to spend on other things, you better start thinking of comparing hdtvs, so you will buy the one that is appropriate for you and your budget.
The best thing to do is actually go to some shops that have a few hdtv sets placed and working on them, so you can start and actually looking at the picture they project and see what you like, and what you dislike. The good thing about making these kind of choices is that they are natural choices, you will go for what you like, and not what the sales person or the details specifications will try and tell you. It is very hard to argue with a sentence like I just like that one better.
Naturally I would not advise you to buy the HDTV in the first shop you walk into, unless they got some really impressive sale going on, try and compare not only prices but the actual TV and their quality as you see it. If the shop doesnt have the high definition television working, ask if they can turn it on for you to see how it looks. Dont be shy, they will make some nice money on your potential purchase.
Once you are in the shop you should be focus don really testing the hdtv, you should think about a few things, the amount of light in the room, the colors of the hdtv and the overall picture quality, the best thing to do is to start from the basic, the normal output of the television, you look at any of the regular TV channels to see how does the basic output looks like. The next step is to ask for a HDTV channel, so you can see how would that look, remember that this is what you are here for and try and spend at least a few minutes looking at the screen, do not rush or let the sales person change channels quickly.
The ultimate testing can be done using a high quality output source like a DVD, try and ask for a really good animation film, or a film with an action sequence (they always have those around the shop, it increases sales) and watch it on the hdtv, if the colors are shape and natural, and the brightness is good you can tell that you got something you like.
Dont forget that when you test an HDTV in the shop it is nowhere close to the conditions you will have at home, the sound system and optimization will probably be less efficient, the room will not have as much light as a store has and there will be no sales person pushing you to buy next to you.
HDTVs are the new television craze, you can see so much better and enjoy a high quality picture quality on many channels, find out how to move into the HDTV era and how to compare and High Definition TV’s at http://hdtv.zupatips.com/

In the field of HDTV products, Sony has made an impressive mark in the market. The first product was launched in 2006 and since then Sony has evolved dramatically in its range. Some of the significant changes were the launching of more products rather than only plasma HDTV and re-branding of the LCD sets to Bravia. The range evolution and improved quality processes has helped the company to gain a reputable name in the market and cover their small misfortunes in the HDTV campaigning.
The re-branding and changes in the HDTV product line up is an effort to overcome the general market reviews of the Sony’s products - their high prices and not too good reliability in the HDTV product range. The newly launched products and improvised versions of HDTV surely is an indication of problem-solution achievability.
Sony offers a broad range of LCD sets which ranges from the smallest, 26 Bravia XBR KDL-V26XBR1 to the largest 46 KDL-46S2000. The largest set provides an impressive 1366 x 768 resolution and Sony’s proprietary Bravia Engine video processor. This set may have comparable features with those of its contemporaries but the price tag of $3,500 makes it a loser in the market.
The product specifications boast of excellent picture quality with good blacks and vivid color reproduction. But practical experience suggests a slight calibration in the set to achieve the optimum indicated levels. For instance, the 720p reproduction in the 40 KDL-V40XBR1 projects a much sharper image, yet the proper color balance is difficult to achieve normally. The KDL-V40XBR1 model also offers a Digital Cable Ready feature with a cable card called DCR and a Quadrature Amplitude Modulation - QAM tuner which is an alternative to the separate, external cable box. This is an excellent add-on but the only thing to be noted is that not all features like the ‘on-demand’ etc. are always supported and the cards compatibility with all cable companies offerings should be checked with the local area’s cable service provider.
Although the picture and sound quality of the LCD are not at the level of the plasma HDTVs, LCDs still offer comparably good viewing angles and are known to perform quite well under varying lighting conditions. Like all brands and most models, the Sony LCD sets are equipped with multiple in-built tuners. These tuners provide reception for over-the-air HDTV broadcasts (e.g. ATSC or Advanced Television Systems Committee).
You can also change the aspect ratio from the HDTV standard 16:9 to that of standard TVs that is, 4:3. Before applying this feature, a preview of how it is done should be ascertained. The cropping by black bars on the screen might be fine with some, but some users find stretching the image displeasing and unacceptable.
The sets come with two component video ports and only one HDMI (High Definition Multimedia Interface) connector in place of the usual two. These connectors are essential for delivering quality images even using standard DVDs on an HDTV set. There is also a USB port and a memory stick slot for connecting a source of digital video and photos to be displayed on the large panel.

Digital Videos (DV) capture images on CCD Charge Coupled Devices but store them in a high-quality, endlessly reproducible, easily edited, digital format. Currently the most commonly device for capturing s is the Digital Camcorder.
The quality of the digital is far superior to the analog counterpart. The images are sharper and the color is richer and more accurate, at least twice as good as the older VHS and almost identical to broadcast quality as DV uses component color sampling to hold thrice the color information as a conventional analog VHS and S-VHS .
Time Base Correction stabilizes the picture thereby virtually eliminating jitters. Error Correction fills in missing data and provides seamless, professional-looking .
In a digital camcorder one can instantly change between capture or playback mode without disturbing any of the other elements and can instantly review the quality of the captured .
Editing is greatly simplified because the can be transferred directly from the camcorder to the computer without conversion using what is called as Firewire connection. It can then be digitally edited on-line and again copied back to a digital tape. Not only it is quick and easy, there is no loss of image quality as there is in the analog world while copying and transferring. In fact, copies of digital s and copies of copies are still as sharp as the original. Once stored on the computer, you can also easily send short clips as e-mail attachments or post them on Web sites.
Digital s have thats CD quality, presently the best rated.
There is a convergence between digital still cameras and digital camcorders. Many of the new digital still cameras can capture short segments and similarly camcorders can also capture digital stills.
DV cameras are smaller than other camera of other formats, with some even slipping into a shirt pocket. DV camcorders store upto ninety minutes of digital on small DV cartridges, which are a bit expensive. Another feature of these DVs is that images can be stored not only on digital cassettes but also on MultiMediaCards known as Flash Cards and the images can be transferred between the two easily.
In its digital mode it stores in excess of 700 still images at 640 x 480 resolution in JPEG format in either of two quality modes. High Resolution mode will store approximately 60 printable images and Standard mode will store 105 images appropriate for email attachments. There are also zoom facilities available, which are normally 10x optical zoom and 40x digital zoom and are backed with an image stabilization system.

PAL Standard
PAL technology is a colour encoding system used in broadcast television systems in a larger section of the world. The other common standards are NTSC and SECAM. PAL is an analogue broadcasting system and is a standard which uses in all 625 alternating lines. It is used on 50Hz power frequency cycle and operated in those countries where such frequency is the standard specification of its electrical power. PAL was introduced as a standard in the year 1967 and has eight different types - PAL B, PAL G, PAL H, PAL D, PAL I, PAL K, PAL K, PAL N and PAL M. These offshoots of PAL have different specifications. PAL is used in China, India, Indonesia, Israel, Laos, Nepal, Pakistan, Thailand, Lebanon, Iraq, Iran, and United Kingdom, some European countries, some countries in South America and also in Africa.
Within Europe, France, along-with some of its neighbours, use SECAM technology, where-as, rest of the Europe uses the PAL standard. It is the dominant standard in the world, with the United States and Japan using the NTSC standard. PAL delivers 625 lines at 50 half frame per second and works on 50Hz power cycle.
NTSC
NTSC is the technology which sets the standard in television and video standard in the United States and provides a composite video signal having a refresh rate of about 60 half-frames per second, interlaced. A frame consists of a packet of data and in this case it would be a packet of composite video signals that a frame would contain. NTSC contains 525 lines and can contain 16 million colours. A composite video would mean a video signal in which all the colours are present, such as, red, blue, and green signals. It may also consist of audio signals at times. These are mixed together to form the composite video signal.
NTSC is essentially an analogue system, developed in the United States and in use in Canada, Japan, South Korea, the Philippines, the United States, and some other countries, mostly in the Americas. The refreshing rate of NTSC standard is 60Hz, and consists of 525 lines per frame. Out of these 525 lines, 485 carry the video information, with the rest are sync pulses, which are not visible. The bank lines have been deliberately put there to give time to the electronic gun in a television to reposition itself.
SECAM
SECAM is an analogue colour television system, first used in France, as a video standard, at the early part of 1960. It is historically the first European colour television standard. SECAM uses the same bandwidth as PAL but transmits colour sequentially. It runs on 625 lines per frame and uses the same frame rate as PAL, 25 frames per second. SECAM is used in France and former French colonies. It is also used in the former communist countries in Europe. Due to the same characteristics that SECAM has with PAL, especially as far as resolution and frame-rate are concerned, DVDs, VCDs, and SuperVHS use PAL internally, but before the signal is available at the output, the colour encoding is changed to SECAM to be displayed on a SECAM TV.
Due to the incompatibility in the video standards, video tapes from one region cannot be viewed in the television of another country, which has a different standard. This means, that a video tape from the United Kingdom cannot be viewed in the United States. The VCR has no capability to convert a PAL video tape to NTSC for viewing. Multi-system VCRs can play video tapes of all standards but it cannot convert the standard to make the video standard compatible with the existing standard of a television. Solution to this problem is to have a VCR with the capability of converting the output signal into a compatible standard for viewing it on a television. This multi-system VCR would have to have a built-in converter for the purpose.
A basic multi-system VCR does not have such a converter built in and a separate stand-alone converter is required to be used, in between the VCR and the television or otherwise you would need a multi-system TV to view the tape. A multi-system TV also has a converter built in, and any VHS tape can be played in any basic multi-system VCR for viewing. Suppose you need to view a PAL video tape on a NTSC television. You shall not be able to view the tape, unless your VCR is a multi-system one and has an inbuilt converter. The PAL tape is read by the VCR and converted to NTSC signals when the output of the VCR is being applied to the TV. If your multi-system VCR does not have a converter, you must have a multi-system television in-order that you may view the tape. The other alternative would be to hook up an external converter in between your multi-system VCR and your NTSC television, when you can view that video tape.
In converting PAL into NTSC, the point to remember is that NTSC video standard has a resolution of 720×480 and a frame rate of 30 frames per second, while PAL has a resolution of 720×576 with a frame rate of 25 frames per second. Therefore, from the above specifications, it can easily be determined that PAL has a better picture quality than NTSC, while NTSC has a better motion picture display because of its higher refresh rate.
Tenlab offers Tenlab converters which is capable of converting any of the video standards into the other. These are stand alone video broadcast standard converters, supporting PAL, SECAM and NTSC. The converter equipment connects to the VCR output with the converter output going into the television’s signal input. Therefore, if you are playing a PAL video tape/disc on your multi-system VCR/DVD, the output of the converter is available as a NTSC standard, compatible with the standard of your television.
Some of the Tenlab models stabilise the picture processing, using a bult-in time corrector and has a video enhancer to provide you with a crisp and clearer picture quality. Tenlab converters are also used by number of corporations. The converters are used exclusively for their professional applications such as worldwide satellite transmissions, MTV Latin America and Gulfstream Aerospace for their on-board multi-system entertainment systems.
Tenlab was established in the year 1988 with a mission to create products solving incompatibility between the different standards existing in video systems around the world. The company introduced the first NTSC VCR capable converter, playing other standard video tapes. Since then Tenlab has gone on to introducing new models and offered upgrading the older ones to the new standards.
110-220 Volt Electronics - A multisystem TV is a TV capable of receiving and displaying different video systems like PAL, SECAM and NTSC. You’ll be able to operate a multisystem TV in 99% of the world. Their dual voltage design allows them to be plugged into either a 110 voltage source or a 220 voltage source. In some cases, the plug on the television will not fit your country’s outlet, so an inexpensive plug-adapter will be needed. They can generally be picked up at an electronics store such as http://www.planetomni.com for $1.95. With a multisystem TV, such as a plasma, CRT tube type, LCD or DLP, you’ll likely need a codefree (sometimes called region free) DVD player. These exist in many forms. When used with a PAL-NTSC TV you’ll be able to see the full 625 lines of resolution available in the PAL system and the full 525 lines used in the USA NTSC system. There exists a converting type of DVD player which is codefree in that it can read all of the world’s 6 regions and both standards, PAL and NTSC. 140,000 other products are available here: http://www.planetomni.com Tel. # 800-514-2984
