and use the 8VSB or the cable modulation scheme to modulate it onto a channel,<br>
and I would not think that putting that on something like USB would take cost<br>
that much to make, so long as the computer was providing the proper bitstream to<br>
start with.<font color="#888888"></font></blockquote><div><br>I don't think that an individual USB 8VSB/QAM modulator would be expensive to produce. Neither do I think that any of the software problems involved in implementing an ATSC video distribution system are hard. <br>
<br>I think it is unlikely anybody will start producing and selling the hardware cheaply anytime soon. When you consider the cost of IR repeaters and their associated wiring, an 8VSB modulator for each simultaneous channel, and hardware that can support realtime encoding of each stream in addition to all the other things you would like it to do, the complete system just isn't much cheaper than putting a networked set top box at each TV.<br>
<br>Eventually we will see cheap ATSC encoder/modulators, but I don't expect to see them soon. There just isn't a market for them.<br><br>-chris<br clear="all"></div></div><br>-- <br>Chris Ribe<br>TV/IT Engineer<br>
