Abstract
One embodiment of the present invention sets forth a method of generating a packet identifier table that comprises reading a packet identifier value from a received transport stream packet, identifying a type of data contained in the received transport stream packet, and generating a table with mapping information between the packet identifier value and the identified type of data.
Claims20
A method of constructing a packet identifier table, comprising:
- in response to a failed attempt to retrieve information descriptive of a structure of a transport stream from the transport steam received by a receiver device within a predetermined period of time, wherein the information descriptive of the structure of the transport stream contains a program information table,
- reading, by the receiver device, a packet identifier value from a received transport stream packet;
- identifying, by the receiver device, a type of data contained in the received transport stream packet;
- and
- generating, by the receiver device, the packet identifier table with mapping information between the packet identifier value and the identified type of data, as a substitute for the information descriptive of the structure of the transport stream to filter the transport stream.
2 more elements
A method for processing a transport stream received at a receiver device;
- comprising:
- attempting, by the receiver device, to retrieve information descriptive of a structure of the transport stream from received transport stream packets, wherein the information descriptive of the structure of the transport stream contains a program information table;
- and
- in response to a failed attempt to retrieve the information within a predetermined period of time, switching, by the receiver device, to a packet identifier scanning mode of operation, further comprising:
- reading a packet identifier value from a received transport stream packet;
- identifying a type of data contained in the received transport stream packet;
- and
- generating a packet identifier table with mapping information between the packet identifier value and the identified type of data, as a substitute for the information descriptive of the structure of the transport stream to filter the transport stream.
5 more elements
A receiver device, comprising:
- a processor;
- a memory system;
- and
- a demultiplexer configured to process a received transport stream in an attempt to retrieve information descriptive of a structure of the received transport stream, the information descriptive of the structure of the received transport stream contains a program information table;
- wherein in response to a failed attempt to retrieve the information within a predetermined period of time, the processor is configured to trigger a scanning mode of operation in which
- the demultiplexer is configured to
- read a packet identifier value from a received transport stream packet;
- identify a type of data contained in the received transport stream packet;
- and
- the processor is configured to generate a packet identifier table that associates the packet identifier value with the identified type of data as a substitute for the structure of the received transport stream to filter the received transport stream.
