Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital TV receiver, and more particularly to program selection means.

[0002]

2. Description of the Related Art Conventionally, there has been known a digital TV receiver for receiving a signal including additional information regarding a program other than audio / video signals. Additional information relating to programs and the like in such conventional digital TV receivers includes EIG (Electronic Program Guide) and EIT (Event Information Table).

In such a conventional digital TV receiver, when a user searches for a favorite program from multiple channels and multiple programs, a method of using the content descriptor in the EIT to divide the program into "Janul" was there. FIG. 4 shows an example in which each genre is displayed as a group 1, a group 2 ... It is possible to select and display a favorite genre (music, domestic pops, etc.) from the group 1, the group 2, ... Or, I was able to display only the programs I wanted to watch.

[0004]

Since the genres of programs are divided into the predetermined genres on the transmission side (broadcasting station side), the genres of programs are not always divided into the genres actually considered by the viewers. Further, there is a problem that it is difficult to narrow down the programs that one really wants to watch because there are too many candidates only by specifying the genre, and it takes a lot of time to find the program one wants to watch.

The present invention has been made in view of the above points, and an object thereof is to provide a digital TV receiver capable of easily searching for a program desired to be viewed.

Alternatively, the selected program is configured to be reserved.

Also, the digital TV receiver of the present invention is
In a digital TV receiver that receives a signal including additional information in addition to audio / video signals, a keyword input by a user is registered, a program is selected by the registered keyword, and program information is displayed, Alternatively, it is configured to reserve the selected program.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A digital TV receiver which is an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a digital TV receiver which is an embodiment of the present invention. Reference numeral 1 shown in the figure is a tuner, which is controlled by the main controller 5 to select and detect a signal of one broadcasting station from a plurality of broadcasting wave signals received by an antenna, and demodulate the detected signal. Output to.

The main controller 5 is provided with a microcomputer and ROM, controls each device by a command from the input device 4 which is connected to each device and the memory 6 by the system bus and is constituted by a key or a remote controller, and is also required. The information is stored in the memory 6.

The demodulation unit 2 is controlled by the main controller 5 to demodulate the input signal and output it to the demultiplexer 3. The demultiplexer 3 separates the signals (transport stream) of the programs, transmission bases, etc., which are compressed and sent under the control of the main controller 5, into individual programs, and outputs the signals related to the programs to the main controller 5. Then, the respective video and audio signals are output to the video decoder 8 and the audio decoder 9.

In response to a command from the input device 4, the main controller 5 causes the memory 6 including a temporary buffer to store information on programs extracted from the transport stream by the demultiplexer 3, information on transmission bases, still image data, and the like. Further, necessary information is taken out from the memory 6, an OSD (on-screen display) control unit 7 generates an image including characters, and
The adjustment / setting of the screen of the video signal, for example, the position of the screen, the brightness and brightness, the chromaticity adjustment, the contrast and the like are adjusted by the user and output to the mixing unit 10. further,
The main controller 5 can record a received program by controlling a recording device (not shown).

The video decoder 8 demodulates the video signal from the demultiplexer 3 and outputs it to the mixing unit 10. The mixing unit 10 combines the signals from the video decoder 8 and the OSD controller 7 and displays them on the display device 12. The audio decoder 9 outputs the input signal as an audio signal to the audio output device 11 and causes the speaker to generate a sound.

In the above digital TV receiver, the keyword extracted by the viewer from the short format event descriptor (notice, program content, performer, original / script, director / director, music, production, etc.) in the EIT is used. It is possible to register, or to register user keywords arbitrarily input by the viewer, combine these keywords with AND or OR to select a program, display the program, or schedule recording.

The operation of registering a word in the EIT as a keyword will be described with reference to FIGS. 2 and 3.
First, when the keyword registration is instructed by the input device 4, the contents of the EIT are acquired in step S1. next,
In step S3, it is determined whether or not there is a user keyword. If not, the process proceeds to step S8, and if there is, the process proceeds to step S5.

Next, in step S5, it is confirmed whether or not the user keyword is in the EIT. Further, in step S5, if the user keyword is in the EIT, the process proceeds to step S7. Moves to step S8. In step S7, the program content including the user keyword is stored in the memory 6, and the process proceeds to step S8.

In step S8, a word is extracted from the EIT and registered as a keyword. The operation at that time will be described with reference to FIG. First, when "Jeunru selection" is selected with the cursor movement keys on the screen shown in FIG. 3 displayed on the display device 12, music / domestic pops are displayed as Jiyanru, and the word "female extracted from the EIT is displayed below it. Vocal, Ayumi Hamasaki, Ballad ”is displayed.

If the displayed word contains a keyword intended by the viewer, for example, "Ayumi Hamasaki", "Ayumi Hamasaki" is selected as the user keyword by the cursor movement key and executed. be registered.

If there is no keyword intended by the viewer among the displayed words, by pressing the next candidate key,
The channels, programs, and jijiyanru of each broadcast are selected one after another, and the words extracted from the EIT are displayed. User keywords can be registered from among them.

When the user key word "Ayumi Hamasaki" is selected on the screen shown in FIG. 3 and EPG is executed, a program including "Ayumi Hamasaki" is displayed in the EIT. Further, when the reservation is executed, a program including "Ayumi Hamasaki" is reserved in the EIT. Alternatively, sound recording can be reserved in the MD recording device.

This routine can be ended by the end key without executing "EPG" or "reservation" on the screen shown in FIG. In this case, "Ayumi Hamasaki" is registered as the user keyword.

[0021]

According to the digital TV receiver of the present invention, the keyword arbitrarily input by the viewer or the EIT
By selecting keywords from the words extracted from the above, it is possible to easily search for a program desired to be viewed by these keywords or make a reservation.
