Description

Program prediction information display control device of television

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for displaying and displaying program prediction information of a television. More particularly, the present invention relates to display information indicating program prediction information based on a time code of the KBPS data upon reception of KBPS data superimposed on a television broadcast signal. To store the information between the channel reservation data for each broadcast program, and to display the display information according to the corresponding program prediction information when executing channel reservation according to a predetermined broadcast program. A program prediction information display control apparatus.

Currently, in the television broadcasting system, for example, 60 channel bands are allocated from each broadcasting station. For example, the number of available channels is rapidly increasing due to cable broadcasting consisting of 30 channels and satellite broadcasting consisting of a plurality of channels. Therefore, when a viewer wants to select a channel where a broadcast program for a specific field is broadcasted among the channels that the viewer can watch, such as 60 channels, in order to accurately tune a specific channel where a broadcast program for a specific field is broadcasted, the broadcast is broadcasted in each channel. This is only possible if you have information about the program.

In consideration of such a trend, channel switching or reservation recording in a video tape recorder can be easily performed by KBPS (Korean broadcasting program system) data superimposed on a video signal of a television broadcast.

At this time, among the channels set by the KBPS data, the channels that can be tuned to on the TV include a plurality of channels that professionally broadcast only programs in a specific field (eg, movies, culture, education, sports), and many viewers It offers convenience to watch programs that suit your taste.

The KBPS signal is transmitted by being included in the 16th line adjacent to the videotext data line in the teletext data line or the like transmitted in the vertical blanking period of the video signal, and the KBPS signal is transmitted on the date / month of the current broadcast program. Data indicating / hours / minutes, country code data on which the broadcast program is broadcasted, and program source code data indicating the type of the broadcast program.

The program source code data is composed of hexadecimal codes indicating the types of broadcast programs. For example, in the case of the code 0g08 'for the classification of the viewer layer, the program source code data represents a broadcast program for a general viewer. Code 0g120h represents a broadcast program for immigrants, and code 0g1A 'represents a broadcast program for adolescents (14 and older).

In addition, as a content of the broadcast program, code 0g430h represents a program related to economy / industry / finance, and code 0g480h represents a program related to science / humanity. Code 0g500h indicates transmission of a broadcast program related to music, code 0g680h indicates a program related to sports, and code 0g700h indicates transmission of a program relating to leisure / hobbies.

Therefore, when the channel search mode is set, a channel searched based on program source code data included in the BPS signal is classified into a plurality of channel groups according to types of broadcast programs, and then a specific channel group is selected. Channel tuning is performed according to the type of broadcast program by enabling channel adjustment within channels classified into channel groups.

However, it is currently possible to make a channel reservation for a predetermined broadcast program through such KBPS data, but it is impossible for a user to later view the program information such as the broadcast date or program time for each channel reserved broadcast program. Therefore, since the time information and the like of the broadcast program can be grasped only after the broadcast program reproduced by the channel reservation ends, there is a disadvantage in that an efficient broadcast viewing cannot be achieved.

Accordingly, the present invention has been made in view of the above circumstances, so that program prediction information for each broadcast program can be stored together as display data during channel reservation of the broadcast program by KBPS data transmitted overlaid on a television broadcast signal. Accordingly, it is an object of the present invention to provide a program predictive information display control apparatus of a television, which enables display information according to program predictive information of a corresponding broadcast program to be displayed on a screen when a scheduled broadcast program is played back.

In order to achieve the above object, according to the program prediction information display control apparatus of a television according to the present invention, an image signal of a predetermined channel selected through a tuner is subjected to an image signal through an intermediate frequency amplifier of an image IF unit and an image signal processing of an image processing unit. In a television which is reproduced and the audio signal of the predetermined channel is reproduced through the intermediate frequency amplification of the audio IF unit and the audio signal processing of the audio processing means, the channel reservation information for a plurality of broadcast programs in the video signal of the tuned channel. KBPS data processing means for receiving and processing KBPS data having data, and storing data for storing channel reservation information for a plurality of broadcast programs set through the KBPS data and program prediction information for each broadcast program reserved for the channel. Means, a plurality of rooms by key setting of a function setting unit based on the received KBPS data Generating channel reservation information for a program, generating program prediction information for each broadcast program, and storing the program prediction information for the broadcast program when the broadcast start time of the reserved channel has elapsed by a timer. Control means for controlling a screen to be displayed on the screen, and display signal processing means for generating display information for screen-displaying program prediction information for a broadcast program of a channel during playback of a reserved channel under display control of the control means. Provided is a program prediction information display control apparatus for a television.

According to the present invention configured as described above, program prediction information for each broadcast program is generated at the time of channel reservation for a plurality of broadcast programs through the KBPS data received from the television, and then reproduced during a predetermined scheduled broadcast program playback. The generated program prediction information can be displayed on the screen in the form of OSD display information.
