High definition television decoder

摘要

A video decoder for decoding data at a high rate uses a plurality of slower slice decoders. A common memory is shared by all slice decoders drastically reducing storage requirements of individual decoders. Slices are allocated to decoders optimally in response to busy signals providing improved performance over known methods. The invention decodes HDTV signals using a plurality of ordinary television resolution decoders. Multiple data streams are also decoded.
