Abstract:
A broadcast receiver includes an input unit, a receiving unit, a control unit, a main memory, a demultiplexer unit, and a decoding unit. A transport stream of digital packetized data includes various data types identified by various parameters within the packet header. A filtering table lists select identifying parameters representing the various data types which are to be stored and processed. Data packets which do not have a select parameter found within the filtering table are ignored by the broadcast receiver. The filtering table is scalable by a control unit to an optimum size, which is the minimum size necessary to store all necessary parameters. A control unit determines the number of parameters required in the filtering table, and scales the filtering table to accommodate that number of parameters.
