Abstract:
1. A video MP3 system comprising: a portable enclosure, the contents of which comprise: a micro-computer capable of controlling data processing steps and other components; a memory device coupled to and controlled by the micro-computer, the memory device comprising stored compressed audio data and compressed video data; an audio/video(AV) decoder coupled to and controlled by the micro-computer; an audio reproducer coupled to the audio/video decoder; and a video reproducer coupled to the audio/video decoder, wherein the compressed video data comprises a motion vector (MV) of an inter-frame, and discrete cosine transform (DCT) DC and DCT AC coefficients of an intra-frame, and wherein the AV decoder is configured to generate a DCT DC coefficient of the inter-frame by using the DC coefficient of the intra-frame and the motion vector of the inter-frame.
