There are different interconnection formats for video to add to all these formats: Analog composite (NTSC, PAL) Y/C or S-video (analog) Digital component (601, 4:2:2) 270 Mbit/s (SDI) DV (FireWire, IEEE-1394) 25 Mbit/s, 5:1 compression As you can see, encoding is partly video format conversion. Interconnections Interconnection formats include analog composite and component, and digital component. All require processing to arrive at the final AVI file format. To this end the video capture card has several components: a composite decoder, analog-to-digital conversion, DV decompression, and possibly hardware scaling. If modern digital tape decks use component recording, why do most video cards have analog composite inputs? For historical reasons analog composite has become a standard for interconnections and is still in very common use.
