BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic program guide (hereinafter referred to as EPG). In particular, the present invention relates to each broadcast channel in addition to text information through EPG information received by an image receiving and output device (eg, a television) in digital broadcasting. An electronic program guide display device and method suitable for further displaying screen information.

In general, in analog television broadcasting, video signals are transmitted through radio waves or cables by AM or FM modulation. However, with the recent development of digital technologies such as digital image compression and digital modulation and demodulation, MPEG (Moving Picture) is also used in conventional terrestrial, satellite, and cable broadcasting. Digitization based on the Experts Group is being performed.

As such, digital broadcasting can provide higher quality services than analog services according to the development of digital video / audio compression technology and digital transmission technology, and can improve interoperability with digital communication media and digital storage media. There is an advantage in that a plurality of broadcast programs can be transmitted in one bandwidth.

Accordingly, in the digital broadcasting system, EPG information is transmitted to easily select a program that a user wants to watch among many programs, and the image receiving and output device receives the EPG information and displays the EPG screen to facilitate the program desired by the viewer. Make a choice.

In the case, the program information table is received and the EPG information is displayed on the screen. The EPG information transmitted in the program information table format includes schedule information such as a program name, a broadcast channel, a program genre, a broadcast start time, a broadcast end time, a program content description, and the like. The information stored in this program information table is useful for constructing the EPG navigation graphical interface.

On the other hand, the program information table for such EPG information is standardized on the data itself, but is not specifically defined on how to display the information. Therefore, even if the same EPG information is received, the EPG screen is displayed in a different format for each manufacturer of the image receiving and output device or for each type of image receiving and output device. However, most of the EPG screens displayed always show the entire broadcast channel list and the time after the current time.

In the conventional EPG display method operating as described above, since program text information for all broadcast channels is always provided, the user has no choice but to select a broadcast channel only through the provided text information.

In addition, even when the EPG information is received while receiving the video screen of the currently selected broadcast channel, only the video screen of the currently selected broadcast channel can be viewed, but the broadcast channel must be selected using only text information for the other broadcast channel list. There was this.
