Video processing apparatus and method

摘要

Uncompressed digital video data representing one or more initial video frames is input from a video source 2 to a disc store 14 via a compressor/decompressor 10 or a bypass path 20 and a data bus 12. Thus, data can be stored in the disc store 14 in either compressed or uncompressed form. Video data corresponding to video frames selected for editing are held in a display store 5 in uncompressed or decompressed form and editing and other image processing operations are performed thereon by an image processor 6 under the control of a stylus/touch tablet or other user operable input device. Edited data is output to the bypass path for storage without compression in the store or to the compressor/decompressor for storage in compressed form in the store. The compressor/decompressor may be configured to effect symmetrical real time data compression and decompression or fractal data compression.
