Abstract:
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, and wherein 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.
