microMPEG4 4-Channel MPEG4 Codec on miniPCI type III The microMPEG4 is a 4-channel MPEG4 Codec on a single type-IIIB MiniPCI module. It is a high-performance but low- power device for real-time capture and compression of up to four concurrent video inputs to MPEG4 standard. Low power, MPEG4 Codec. Smaller than a credit-card. The microMPEG4 utilises 32bit PCI architecture to allow high-quality real-time video and audio capture and compression of up to four concurrent PAL or NTSC video sources to disk while at the same time providing an additional path for incoming video to be previewed on the host screen.
