Abstract: A method and an apparatus perform an inverse telecine procedure on a video sequence to eliminate redundant information introduced by the telecine process, so as to achieve more efficient data compression. The method and apparatus maintain synchronization between audio and video portions of the video sequence by ensuring that 20% of all frames, distributed substantially uniformly over the video sequence, are deleted. One embodiment of the present invention is provided in desktop computer system.

Abstract: In a video system having an encoder and multiple decoders, a snooping circuit in each decoder compares an address on a common data bus to determine whether encoded video data is read or written by a host computer. When the address on the common data bus is detected to be an address within a predetermined range, the read or write data on the common data bus is latched into a first-in-first-out (FIFO) memory. A decoding circuit in each decoder decodes from the FIFO memory to provide a decoded video data output stream. In this manner, multiple decoders can be supported by the video system without additional bandwidth demand on the host computer.

Abstract: A system for digital video editing and publishing is disclosed including a video capture unit, a video compression unit, and video decompression unit coupled to a host computer having video editing capabilities. This system allows video editing to occur using intraframe-only compressed video data. The edited video data can then be decompressed and recompressed to provide compressed data, which is compressed using both interframe and intraframe operations, usable for publication in a removal storage medium, such as a compact disk or a data network.
