ABSTRACT:
Potable multimedia terminal which is small and consumes low power, can process a large quantity of multimedia data such as video and audio data. Portable multimedia data input/output processor can be made smaller by using a pen as an input device and can also process a large quantity of multimedia data at a high speed by adopting a PCI bus as a local bus of a system. To retrieve, compress, and decompress multimedia data, main components of this portable multimedia data input/output processor are comprised of audio codec for compressing and decompressing audio data, video codec controller for compressing and decompressing video data, and multimedia processor for transmitting audio data to wireless communication controller and video data to video codec controller and to graphic processor. The method for retrieving multimedia data includes steps of receiving data, de-interleaving received data into audio, video, and graphic data, decompressing the data, and outputting the data to output device. The method for compressing data includes steps of inputting video data to video codec controller, compressing video and audio data at video codec controller and audio codec, interleaving the compressed data, and transmitting them to a remote system. The steps to decompress data are in reverse to the steps to compress data.
