A device for transport stream processing is provided. The device includes a plurality of data inputs and a transport stream re-multiplexer for receiving a plurality of data streams from the plurality of data stream inputs and multiplexing the data streams into a transport stream. A transport stream processor receives the transport stream, de-multiplexes the transport stream to process one or more of the data streams, and provides the processed data stream to the transport stream re-multiplexer as one of the plurality of data streams.

Multi-format stream re-multiplexer for multi-pass, multi-stream, multiplexed transport stream processing

A system for processing a stream of data and automatically selecting a portion or all of the data stream for block writing to a memory. The memory is capable of storing data in response to a block write command and a normal write command. The system contains a first data register and a second data register having the same data width. The first data register accepts data from the data stream in accordance with the its data width. Data stored in the first data register is transferred to the second data register. The first data register is then loaded with a portion of the data stream which is contiguous to the data stored in the first data register prior to the transferring. The data in the first and the second data registers is then compared. If the data in the first and the second registers is the same, then the content of a data counter is increased by one. When the content of the data counter exceeds a predetermined value, the system executes a block write command.
