we are about to start a custom ATSC/HDTV receiver development work. It uses Phlips tuner and NxtWave's VSB demodulator. Our customer will be putting out the product in the 3rd quarter this year.
I think that this whole thing is an exercise in futility. ATSC signals are one of the easiest to hack into, since the standards are well known and can be downloaded from atsc.org. Tuners are available from a number of sources. The VSB demodulator may not have many suppliers. I do not think that there is something called "ATSC Tuners". The Philips tuner can output the IF and CVBS signals from both ATSC and NTSC broadcasts. If one need to decode NTSC, then the IF/CVBS is fed to a broadcast decoder otherwise to the VSB demodulator, which outputs TS. regds...das At 09:15 PM 3/27/02, you wrote: >A group of industries meeting in Los Angeles is planning to recommend >to Congress that regulations be imposed on all devices capable of >receiving and demodulating ATSC broadcast signals.
