Abstract

A digital television signal receiver, which includes an audio processor to process the audio data to be output as sound; a video processor to process a video data to be output on a screen; a storage to store the extracted program information; a processor to access the storage to generate a channel list based on the stored program information; wherein the channel list comprises at least one main channel number and the at least one main channel number has at least one corresponding sub-channel number in the received transport stream; a user interface to allow a user to navigate the channel list to search a channel number.

Claims

1. A digital television signal receiver, comprising:

a converter to convert a received radio frequency (RF) digital broadcast signal into a baseband signal;

a decoder to decode the converted baseband signal to reconstruct a digital broadcast transport stream which includes audio data, video data, and program information;

an extractor to extract the audio data, the video data, and the program information from the reconstructed digital broadcast transport stream and storing the extracted program information in a storage of the digital television receiver;

an audio processor to process the extracted audio data to be output as sound;

a video processor to process the extracted video data to be output on a screen;

a processor to access the storage to generate a channel list based on the stored program information, wherein the channel list is made up of one or more separately identifiable channel groupings, each having one or more two-part channel numbers, where each of the one or more two-part channel numbers includes a main channel number as a first part and a sub-channel number as a second part, and where each two-part channel number of a respectively identified channel grouping has a same main channel number and different sub-channel numbers; and

a user interface to enable a user to navigate the channel list to search a two part channel number, wherein information included in the channel list is derived from program associated information from a Program Specific Information (PSI) table, for plural programs included in the transport stream conforming with an MPEG standard, wherein an identifiable program according to the MPEG standard is distinguished from a predetermined corresponding two-part channel number,

wherein the channel list is configured to be navigable in a first direction between one or more two-part channel numbers of a first channel grouping, and navigable in a second direction between the first channel grouping and the second channel grouping, and

wherein the first direction is different from the second direction.

2. The digital television signal receiver of claim 1, wherein the PSI table is a received PSI table conforming with the MPEG standard.

3. The digital television signal receiver of claim 2, wherein a processor generates the channel list so as to be shown in a single display window and the navigation of the channel list is enabled to be performed in a two-dimensional number-based order on the single display window, with the window being vertically and horizontally embedded with two-part channel numbers.
