Method of acquiring program guide information, program guide method appropriate for the same, and program guide apparatus
First Claim
1. A method of channel searching for a digital television receiver, comprising:
- receiving a digital broadcast signal that includes audio data, video data, and additional information;
extracting the additional information from the digital broadcast transport stream and storing the extracted additional information;
generating a channel list that is designed to be shown in a single display window, based on the stored additional information so as to enable a user to navigate the channel list to search a two-part channel number,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 identifiable channel grouping has a same main channel number and different sub-channel numbers,wherein the navigation of the channel list is enabled to be performed in a two-dimensional number-based order on the single display window, between two-part channel numbers of a channel grouping or between channel groupings, where the window is vertically and horizontally embedded with two-part channel numbers, andwherein information included in the channel list is derived from program associated information in received Program Specific Information (PSI) table data conforming with an MPEG standard, for plural programs included in a transport stream conforming with the MPEG standard, where an identifiable program according to the MPEG standard is distinguished from a predetermined corresponding two-part channel number.

Abstract
A method acquires program guide information in an image signal receiver, and program guide method and apparatus use the same. In the program guide apparatus, information immediately required by a user is obtained first, and information of less preferential channels is obtained next, thus presenting a smooth interface to the user. The method of acquiring program guide information for channels includes acquiring the program guide information for each channel by scanning accessible channels while a received program is not displayed. The program guide apparatus includes a tuner tuning a channel, a program guide information detector, a memory, a key input, a microprocessor, and a character signal generator.

8. A method of channel searching for a digital television receiver, comprising:
-
converting a received radio frequency (RF) digital broadcast signal into a baseband signal and decoding the converted baseband signal to reconstruct a digital broadcast transport stream which includes audio data, video data, and program information; extracting 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; processing the extracted audio data to be output as sound; processing the extracted video data to be output on a screen; accessing 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 enabling 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 between two-part channel numbers, of one or more two-part channel numbers of a first channel grouping, and between the first channel grouping and a two-part channel number of a second channel grouping, wherein the channel list is navigated in a first direction between the one or more two-part channel numbers of the first channel grouping, and navigated 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. - View Dependent Claims (9, 10)
