DIFFERENCE BETWEEN HD AND HD READY TV TV

This can also work with DVD players and is generally known in the industry as upscaling, taking a low resolution image and artificially boosting it to a higher resolution format)

DIFFERENCE BETWEEN HD AND HD READY TV TV

(caveat: many TV systems can вЂњinterpolateвЂќ and artificially produce transitional information between lines, effectively producing a higher resolution image. Not much when you have a screen the sprawls across 40-50вЂі or even larger. Worse, itвЂ™s still interlaced, so each frame is really only 240 horizontal lines of information. The result is that the default TV video signal is 480i, which means that your entire image is only comprised of 480 horizontal lines, even on a really big screen. In the early years of television technology there simply wasnвЂ™t the bandwidth to send that much information, but now there is, and more. ThatвЂ™s whatвЂ™s called вЂњprogressiveвЂќ video and each frame has lines 1, 2, 3, 4, 5, 6, etc. Problem is, it really would be better to have all the image information each sixtieth of a second and youвЂ™d have an image that would be ostensibly twice as visually stable and attractive. Works faster than your eye can recognize the sleight-of-hand and the result is smooth transitions and smooth motion, even during action scenes. So you get lines 1, 3, 5, 7, etc., the a 60th of a second later, you get lines 2, 4, 6, 8, etc. Interlacing means that half the image is sent on each refresh, alternating between the even numbered and odd numbered horizontal lines of information. While youвЂ™re reading, though, a quick primer: North American television has a fast refresh rate of 60 frames/second (versus the European PAL format which works at 50 fps), but the way it does that is through a sneaky technology called вЂњinterlacingвЂќ.

For the same price, you should unquestionably be able to find an alternative unit that is HD ready, and skip the silly converter box entirely when the big switchover comes to pass in 2009. My advice: itвЂ™d be insane to spend the money for a high-def television that was only вЂњHD capableвЂќ at this point in time. Honestly, it seems to me that with the addition of a simple digital-to-analog converter (see ) you could say that every analog TV is вЂњHD capableвЂќ.

Some companies donвЂ™t want to admit that their TV systems arenвЂ™t ready for a pure-digital television signal coming into the device, though, so they say that theyвЂ™re вЂњHD-capableвЂќ. As IвЂ™ll be writing about later this week (stay tuned for the link here) all television broadcasts will be 100% digital starting in 7 February, 2009, so if you have a TV that requires an analog signal, you will need a converter. In a nutshell: HD-ready sets have the HDTV program receiver/decoder built-in, while HD-capable sets require the addition of an external receiver/decoder needed to receive digital broadcasts.

Let me start with your answer, then IвЂ™ll offer up a bit more information about high-definition television technology and related. Between HDMI, Component, S-Video, 1080p, 1080i, 720p, 480p, Blu-Ray, HDDVD, 5.1, 7.1, 2.1, PAL, NTSC and oh, so many more elements of HDTV technology, if you have really got it all figured out except вЂњHD capableвЂќ and вЂњHD readyвЂќ, then youвЂ™re ready to be lead salesperson at Circuit City, I think! If you have figured out all the other terminology involved with modern television technology, I am quite impressed.
