A multimedia decoder for prioritized bi-directional communication in a broadcastsystem

摘要

A multimedia decoder supports a plurality of functions and communicates on at least one physical communication link. The decoder includes a first processor for decoding data packetized according to an Internet protocol data format to provide a first decoded output. The decoder also includes a second processor for encoding data according to the Internet protocol data format for return communication to a broadcast source. The decoder prioritizes received data for processing by the first processor and prioritizes data for encoding for return communication by the second processor. The received data and the data for encoding are allocated a desired hierarchical data output priority based on a function or a protocol characteristic of the data to be prioritized.
