What Is a Mini Video Card?

The compression card is to decode or encode analog signals or digital signals and collect the signals into a hard disk or burn them directly to a disc according to a certain algorithm. Because it is compressed, it has a small capacity and flexible format (MPEG-1 \ MPEG- 2 \ MPEG-4 \ WMV \ RM ...), common compression cards are hardware compression cards, whose compression ratio generally does not exceed 1: 6, software compression cards are different, and its compression ratio depends on the software There are no standards for a few comparisons. Compression generally has intra-frame compression and inter-frame compression. The advantage of hardware compression cards is that they do not need to occupy PC resources, so PCs with lower configuration can also capture good quality video files (VCD / DVD), software compression is different, it requires a higher PC configuration video compression card video compression card.
