MCFLY!!!
That bandwidth will be clogged with dozens of not 100's of regular HDTV feeds by 2006 if the FCC has their way and if I'm not mistaken HD feeds take about the same bandwidth as 6 regular NTSC feeds so no matter what happens, bandwidth will be a premium both for HSI streaming services as well as their regular DCATV/HDCATV services.
It's not as simple as that. You can have 2 HD and a SD or two in a 256QAM with Rate Shaping. If you look at 1 analog channel that takes up 6Mhz of spectrum and you replace it with 2 High Def's and 1 Standard Def in a 6Mhz wide QAM. your getting 3 channels for the price of 1. I fail to see your logic.
A 8VSB over the Air carrier has a HD and a SD |
