Patent ID: 7756391

Claim:
A video editing apparatus for performing video editing in real-time of video streams, the apparatus comprising: a video decoder for producing uncompressed digital video streams from said video streams; a storage device for storing video data; a codec for providing at least two real-time uncompressed digital video streams from at least one of said video data provided by said storage device and said uncompressed digital video streams provided by said video decoder; a graphics accelerator chip having at least two video inputs for receiving said at least two real-time uncompressed digital video streams, said graphics accelerator chip further having a 2D graphics engine and a 3D rendering engine respectively for providing 2D and 3D functions used for said video editing of said at least two real-time uncompressed digital video streams, said graphics accelerator chip further comprising a video output for providing edited uncompressed digital video streams; a video encoder for providing a display signal from at least one of said uncompressed digital video streams and said edited uncompressed digital video streams; a first video bus for transferring said uncompressed digital video streams from said video decoder to said codec, and for transferring said edited uncompressed digital video streams from said video output to said video encoder when said apparatus is operating in a real-time video editing mode; and a time division multiplexed bus for transferring said at least two real-time uncompressed digital video streams from said codec to said at least two video inputs when said apparatus is operating in a real-time video editing mode.
