[streaming] need to set up a US digital TV demo

[Jerry Scharf]

I am new to the list and did not find any information in the archives. I am 
trying to create a US terrestrial broadcast comparison and was hoping your 
software could do this. I have someone who is completely convinced that 
when you put video on top of IP, it will always look bad. So I want to set 
up a demo that can show him as close as I can to a identical setup demo.

What I an thinking of doing is the following (I live near San Francisco):
Set up an antenna pointing at the local broadcast tower. Start with a 
standard 4:3 aspect ratio NTSC television. Put a splitter on the antenna 
and run one side to the antenna input of the TV. Route the other side into 
a PC based tuner that will extract the transport stream of the same 
station, then put it on the wire as a UDP packet stream (about 4Mbps for US 
terrestrial.) Then have another PC catch the UDP stream, decode it and send 
out a s-video port and back to the TV. So you can look at the same 
broadcast at the same time by flipping the TV between the antenna and 
s-video ports. I want to avoid all transcoding so the signal quality will 
be as good as possible on the reconstructed image.

I have seen four or five PCI cards that will receive US terrestrial digital 
tv, but nothing that can hook them up to IP streaming software or turn it 
back to video on the other end.

What is at stake here is whether a proposed local fiber plant in Palo Alto 
will use a separate analog video delivery system or use IP. Until we can 
demonstrate that that a digital system looks as good or better, we will get 
an analog system that will soon be obsolete.

many thanks,
jerry
