ABSTRACT:
Motion video may be imported into a personal or portable computer through an I/O port having a limited data bandwidth, such as a PCMCIA interface. Motion video data is compressed by sub-sampling both luminance and chrominance difference data for different sized groups of pixels. The compression apparatus may be formed on a PCMCIA card which interfaces with a personal or portable computer. Motion video data, compressed by as much as 5:1 or 6:1, is transferred through the PCMCIA card to a host computer. The host computer may serialize the compressed data and store the data in serialized compressed format in a video memory of a video controller. The video controller is provided with decompression circuitry to decompress the motion video data into luminance and chrominance difference data. The luminance and chrominance difference data is converted into RGB data and displayed in a video display.
