First Claim
1. A method of channel searching, comprising:
- extracting additional information from a transport stream for audio and video information, with the additional information including Program Specific Information (PSI) table data conforming with an MPEG standard and information transmitted according to an advanced television standard committee (ATSC) standard;
generating a channel list based on the additional information, where the channel list is made up of one or more grouped plural channel numbers, such that each channel number of a respective grouping of channel numbers is identified by a two-part channel number having a same main channel number, as a first numeral part of each two-part channel number, and one or more distinct respective sub-channel numbers, as respective second numeral parts of each two-part channel number, and where each of the one or more grouped plural channel numbers are represented by two-part channel numbers having respectively different main channel numbers; and
providing a user interface to allow a user to navigate the channel list to search a two-part channel number,wherein the generating of the channel list comprises incrementally providing program information from the additional information through the user interface by respectively updating the channel list as different program information for different two-part channel numbers is obtained from the transport stream, including respectively incrementally providing respective program information based upon determined proximities between one or more two-part channel numbers in a first channel list and additional two-part channel numbers whose program information is to be subsequently provided through the user interface with the one or more two-part channel numbers in the first channel list upon an updating of the first channel list.

Abstract
A method of acquiring program guide information for a digital television receiver, and program guide method, are provided. A method of channel searching for a digital television receiver, comprising: receiving a digital television transport stream (TS) which includes audio, video, and program information; extracting the program information from the received TS; storing the extracted program information in a storage; accessing the storage to generate a channel list based on the stored program information, wherein the channel list comprises at least one channel number and the at least one channel number comprises at least one main channel number; and navigating the channel list to search a channel number, wherein when the at least the one main channel number has at least one corresponding sub-channel number, the sub-channel number can be listed after the at least one main channel number.

9. A method of channel searching, comprising:
-
converting an IF signal from a tuner of the-a receiver into a baseband signal; channel decoding the baseband signal to reconstruct a transport stream which includes audio, video, and additional information; extracting the additional information from the reconstructed transport stream, with the additional information including Program Specific Information (PSI) table data conforming with an MPEG standard and information transmitted according to an advanced television standard committee (ATSC) standard; storing the extracted additional information in a storage; and accessing the storage to generate a channel list based on the stored additional information, where the channel list is made up of one or more grouped plural channel numbers, such that each channel number of a respective grouping of channel numbers is identified by a two-part channel number having a same main channel number, as a first numeral part of each two-part channel number, and one or more distinct respective sub-channel numbers, as respective second numeral parts of each two-part channel number, and where each of the one or more grouped plural channel numbers are represented by two-part channel numbers having respectively different main channel numbers; and providing a user interface to allow a user to navigate the channel list to search a two-part channel number, wherein the generating of the channel list comprises incrementally providing program information from the additional information through the user interface by respectively updating the channel list as different program information for different two-part channel numbers is obtained from the transport stream, including respectively incrementally providing respective program information based upon determined proximities between one or more two-part channel numbers in a first channel list and additional two-part channel numbers whose program information is to be subsequently provided through the user interface with the one or more two-part channel numbers in the first channel list upon an updating of the first channel list.
