Where can I find listings for ExpressVU's network listings for HDTV programming of US networks? I just want to see what is on and when before I drop another $1000 on more equipment that might end up in my storage room. Thanks!!!
Although all set-top boxes, technically known as Integrated Receiver-Decoders or IRDs, include full MPEG2 decoding hardware, until the fall of 1995, the actual signals transmitted were in the older MPEG1+ format, but using the MPEG2 syntax. The IRDs are backward compatible with MPEG1, which is for practical purposes, a subset of MPEG2. IRDs automatically operated with full MPEG2 compatibility without any change required, as the MPEG2 encoders were gradually put on-line during the late summer of 1995.
