A lot of the cheaper PCIe capture boards are pretty "Dumb" and consume a crazy amount of CPU to encode shows.. I hope as we move to APU these cards will at least adapt to use some of the "Advanced" part of the processor to do HW assisted encodes so PCI can fade away.
I'm really excited to see what pricepoint AMD hits with CPU+MB combinations.. we'll see if they price for war, or price competitively. Would love to get a new CPU+MB for less than the cost of the Intel Sandybridge CPU like they did with the phenoms but not sure they will price that insane again
Most capture cards in serious use these days use the broadcasters' encoding don't they?
ATSC, QAM, DVB-S/S2, DVB-T/T2, DVB-C capture cards are surely the norm for broadcast TV capture these days - and none of these require the PC to do any encoding at all - they just pass the already-encoded MPEG2 transport stream (carrying MPEG2 or H264 encoded video and AC3, AAC or MP2 audio) to the PC.
Analogue SD capture solutions were available with both on-board MPEG2 encoding/compression in hardware (PVR-150 from Hauppauge was popular ISTR?), as well as with straight uncompressed video pass-through for the PC to compress in software (Brooktree based devices), though who captures analogue SD video these days?
The HD PVRs and Colossus solutions are analogue (and non-HDCP HDMI for Colossus) HD capture solutions that use onboard H264 encoding.
The Blackmagic Intensity stuff (and similar device) I guess is still capturing uncompressed, and uses CPU rather than on-board hardware for compression/encoding, but that's quite niche.
