摘要
An encoder and decoder system for realization of complexity scalability in a layered video-coding framework. The layered video encoder comprises a base layer encoder for receiving a video signal and outputting a base layer stream; and an enhancement layer encoder that includes a plurality of discrete cosine transform (DCT) modules and a selection system for selecting one of the DCT modules. The layered video decoding system comprises a base layer decoder for receiving and decoding a base layer video stream; and an enhancement layer decoder for receiving an enhancement layer video stream and the decoded base layer stream, and generating a decoded enhanced video output, wherein the enhancement layer decoder includes: a plurality of inverse discrete cosine transform (IDCT) modules; and a selection system for selecting one of the IDCT modules.
