Aren't USB(2) too slow and unreliable for serious HTPC/media center users?
USB2 is fast enough.
For ATSC, the MPEG2 stream of packets is 19.39Mbit/sec which
is 2.4MB/sec. USB2 when used for mass storage is 30MB/sec.
For NTSC, if the capture chip was "dumb" and no compression
was used, that would be a higher rate. Perhaps 20MB/sec from
a BT878 for example. And that would still fit in a USB2 pipe.
I don't think the capture mode captures simple RGB 24 bit color,
and the capture mode uses something a bit more economical than that.
I can't find any details on it.
