摘要
A recordable DVD disk which includes a read-only sector for specifying a video encoding algorithm to be used for compressing video programs that are to be recorded in the recordable region of the recordable DVD disk. Such disks may be used in a digital video recording system having a programmable video encoder. In one embodiment, the system accepts the recordable DVD disks having a read-only sector for storing customized video encoding algorithms and programs the programmable video encoder with the customized video encoding algorithms prior to encoding and recording a video signal on the disk. By designing the video encoding algorithms to optimize one or more of a number of desirable attributes, the DVD media vendors can then create “classes” of recordable DVD disks, i.e. high capacity, high quality, high speed, high image detail, high color resolution, variable frame rate, etc. One programmable video encoder for this embodiment would include an instruction memory for storing the customized video algorithms, a video buffer for buffering the video signal, and a CPU which encodes the video signal according to the customized video algorithms.
