True. What would be nice would be a CPU with a built-in DSP, so that the
CPU can handle the network stuff and OSD and so on, and the DSP could
do the heavy-duty decoding work.
How "realtime" does this need to be? Can we not implement the
networking stuff on the DSP?
I don't suppose Sony would let us borrow their Cell design?
What about something a little lighter than Theora? We don't really need
that much compression on a 100MBit network. Something like HuffYUV
(Lossless, http://neuron2.net/www.math.berkeley.edu/benrg/huffyuv.html)
or MJPEG perhaps?
I'm planning on implementing RGB <-> YUV conversation, at least.
Rather than spending bunches of CPU time doing the matrix algebra, we
can do it in hardware and save at least SOME converstion time.
