Comment Some food for thought (Score 1) 326
4 years ago I was standing at WHD@CBS (the testing grounds for the ATSC Grand Alliance) in Washington, demo'ing datacasting over ATSC.
Not so interesting, except for the fact that Panasonic had two engineers from Japan with a demonstration of HD-DVD. Their prototype demo with two black boxes and a (at that time) prototype 50"+ plasma display used existing DVD discs, and it worked.
On the other side, professional MPEG2 encoders are no longer required to use 14-16Mbits CBR to encode HD. A lot of optimization has taken place in the last 5 years. VBR and optimized motion estimation have squeezed the bitrate all the way down to 1Mbit on still scenes.
Food for thought. Ask yourselves why we need new discs, players, and compression. CSS was a screw-up, and they are looking for any way possible to make this new delivery platform as hard to pirate as possible, with bullshit reasons as an excuse.
It is also a known fact that many people (standards body members) would prefer to use MPEG4 (pt10, whatever) to carry HD-DVD, since with this it can fit on existing discs, albeit requiring a new hardware dvd decoder that supports the codec. I'm sure that will not happen, for reasons we all know.
