Description

Program guide searching device and method of digital satellite broadcasting

The present invention relates to an apparatus and method for retrieving a program guide of digital satellite broadcasting. In particular, in order to easily search for a program guide in a digital satellite broadcasting system, the keypad of the remote controller can be alphabetically searched for text of the program guide. The present invention relates to a program guide search apparatus and method for digital satellite broadcasting. There is a problem that a user may feel bored because it is found again from the beginning.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a program guide search method for digital satellite broadcasting that can be searched by inputting a keyword by providing a character input key or assigning a character to an existing numeric key. The data of the data is output to the encoder section, and the program is watched on a television.

1 is a block diagram showing the configuration of a program guide retrieval apparatus for digital satellite broadcasting according to the present invention.

Hereinafter, the present invention will be described in detail with reference to the drawings. The satellite 21 receives a radio wave transmitted from a terrestrial broadcasting station while transmitting at an altitude of thousands of kilometers without gravity, and transmits it to the satellite reception antenna 22 installed on the ground. Displays program guide consisting of program name, date and time, channel number, and so on. When the user views the program guide displayed on the screen of the television 24 and selects a desired channel and presses a selection key, the controller 50 receives the selected channel through the remote controller input unit 70 or the key input unit 60 and receives the MPEG decoder 30. ) And the data of the video signal and the audio signal of the corresponding channel program are output to the encoder 40 in a plurality of channels output from the demultiplexer 20 to watch the corresponding program on the television 24. By separating the signal, the program guide data matching the keyword is extracted from the program guide data, and the program guide composed of the number, the name of the program, the date and time, the channel number, etc. is displayed on the screen of the television 24 as shown in FIG. do. In operation 308, it is determined whether a channel selection key is input through the remote controller input unit 70 or the key input unit 60. If the channel selection key is not input, repeating step 307. If the channel selection key is input, the channel selected in step 309 is input to control the MPEG decoder 30 to control the multiplexer 20 output from the demultiplexer 20. In the channel, the video signal and the audio signal data of the corresponding channel program are output to the encoder unit 40 to watch the program on the television 24.

As described above, the present invention saves time by searching the entire program by searching the channel by keyword method, and saves time by inputting a keyword that matches the user's taste even if the user does not know the program contents. Since the list of the corresponding programs can be searched, it is impossible to read and pass over the fast-paced text, and the user does not feel bored by searching for the same type of program as the desired program.

Claims (4)

An apparatus for searching for a broadcast program, comprising: a key input unit including character keys and numeric keys to output character data and numeric data; and searching for the keyword in the program guide data received from the key input unit. And a control unit for displaying on the screen. A device for retrieving a program of satellite broadcasting, comprising: tuning a broadcast signal transmitted from a satellite, converting a received high frequency signal into a digital signal, channel correction, and then outputting a transport stream in packet units of MPEG 2 And a demultiplexer for selecting a specific channel according to program designation information included in the transport stream output from the channel unit according to a control signal, and decompressing the video data and the audio data by decompressing the video data output from the demultiplexer. An MPEG decoder for outputting the PDU, an encoder unit for converting and outputting video and audio data output from the MPEG decoder into a video signal and an audio signal, and controlling each unit to read program designation information included in the transport stream. Searches for keyword data entered and sends the text data. Digital remote control comprising a control unit for outputting to the vision, a key input unit for outputting the keyword data to the control unit, and a remote control input unit for receiving the key input data from the remote control unit and outputs the key input data to the control unit. Program guide search device. The program guide of claim 1, wherein the controller receives the keyword data input from the key input unit or the remote controller input unit, separates a text signal from a broadcast signal tuned and output from the channel unit, and matches a keyword from program guide data. And extracting data to display a program guide consisting of a number, a program name, a date and time, a channel number, and the like on a screen. In the program guide search method of satellite broadcasting, when a program search key is input, a guide search screen is displayed, when a text term is selected, a keyword input field is displayed on a television screen, and keyword data is determined by determining whether keyword data is input. If the search key is input, the input keyword is displayed in the keyword field. When the search key is input, the text signal is separated from the broadcast signal. The program guide data corresponding to the keyword is extracted from the program guide data and displayed on the TV screen. And outputting the data of the video signal and the audio signal of the corresponding channel program to the encoder and viewing the program on a television.
