Abstract
Described are methods and apparatuses for tuning television channels that transmit either PSIP Transport Streams or non-PSIP Transport Streams. Specifically, PSIP Transport Streams contain PSIP sections that include a major channel number and minor channel numbers, whereas non-PSIP Transport Streams do not contain such PSIP sections. However, both PSIP and non-PSIP Transport Streams contain PAT sections. Upon receiving a PSIP Transport Stream from a television channel, the present methods and apparatuses directly obtain the major channel number and minor channel numbers from the PSIP section contained in the PSIP Transport Stream. Upon receiving a non-PSIP Transport Stream from a television channel, the present methods and apparatuses form the major channel number and minor channel numbers based on the information contained in the PAT sections. In so doing, the methods and apparatuses can process both PSIP and non-PSIP Transport Streams.
