There seems to be a general misconception that H.264 provides some sort of quantum leap in how a TV multiplex can be organized. It does not. At the bit rates and image quality levels expected for SD and HD television, what you can do with H.264 you can also do with H.262, although marginally better. Meaning, it's not that you CANNOT fit (for example) two 1080i programs in a 19 Mb/s channel with MPEG-2 compression. It's that doing so with H.262 will create some amount of additional glitches or artifacts, or slightly softer images, compared with H.264. And a panel of judges will notice the difference. This should not be confused with "it can't be done with MPEG-2 compression." It's not all or nothing. It's shades of gray. We have seen proof enough of this already, in real systems. > ANY COUNTRY that has not launched a DTV service would be > derelict in their responsibilities to limit a DTV system > to MPEG-2. Obviously, any clean sheet design should start with the most advanced tools available. But in the case of Brazil, it's not like they are going to add content to H.264, so this is not instrumental to their social agenda. > Aparently Bert has learned NOTHING by observing the way > the Internet proliferates software based technologies. > DTV should be no different.
