ABSTRACT:
A method for displaying digital broadcast channel information on a digital broadcasting receiver, which includes searching for an unused reserve communication path among all communication paths over which digital broadcast data is transmitted; sequentially extracting identifiers of channels other than the one currently selected from digital broadcast channel guide information and receiving video data of a program, which is being broadcast on a channel corresponding to a first extracted identifier, through the reserve communication path; processing the received video data to extract image data from the video data, extracting digital broadcast channel guide information corresponding to the image data and displaying the extracted information together with the image data; and receiving video data of a channel subsequent to the channel corresponding to the displayed image data through the reserve communication path and processing the video data.
