Description

Digital broadcasting receiver for reservation recording by detail

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to digital television (DTV) and digital terrestrial television (DTTV), and more particularly, to a digital broadcast receiver capable of making a reservation recording for each item of a desired program.

With the advent of the digital broadcasting era, the development of digital television having various functions is being promoted. Digital televisions have various functions such as a memo function with a memory, a communication modem with a communication modem, and a function of presenting a multi-channel broadcast program on a screen so that a user can easily select it. In addition to such a function, a reservation recording function is provided. In general, when a reservation recording is performed, the user stores broadcasting time information and channel information of a program that the reservation recording is desired. Then, the conventional reserved recording apparatus checks whether the reserved broadcasting time and the current time are the same, and if it is the same, changes the channel to the reserved channel and performs the reserved recording.

However, the conventional method of reserved recording only with broadcasting time information and channel information does not support multi-channel digital broadcasting.

Accordingly, an object of the present invention is a reservation recording apparatus corresponding to multi-channel digital broadcasting, and in selecting a reservation recording data from program guide data, a digital broadcasting receiver which selects and reserves recording by sub-items of the same program in multiple channels. In providing.

In order to achieve the above object, a digital broadcasting receiver for reservation recording according to sub-items according to the present invention outputs a key input unit for applying a key signal for reserving recording, and separates video, audio and data streams from the input TS stream. A signal separation unit, an A / V signal processing unit for receiving and outputting video and audio streams from the signal separation unit, and a display unit, and a storage unit for storing video and audio streams corresponding to a reserved program. The EPG data is extracted from the data stream from the signal separation unit and displayed on the display unit according to the key signal of the key input unit. The reserved recording information is selected on the EPG data, and the reserved recording selected from the TS stream from the signal separation unit is selected. Store video and audio streams with information that matches the information in the storage A control unit for controlling to perform screen.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a digital broadcast receiver for recording reservation by sub-items according to an embodiment of the present invention. 1 includes a key input unit 11 having keys for setting a reservation recording, and a control unit 12 and a storage unit 13 for controlling each configuration to reserve recording according to a key input of the key input unit 11. do. The apparatus also receives an audio signal and a video stream separated from the tuner 14 receiving the broadcast signal, the demultiplexer 15 connected to the tuner 14, and the demultiplexer 15, and processing the MPEG signal to output the screen. A processing unit 16, a speaker 17, and a display unit 18 are provided.

The operation of the apparatus of FIG. 1 configured as described above will be described in detail.

If the user wants to record only the stationary items in the news broadcast on the multi-channel, the user inputs a setting key for the reservation recording using the key input unit 11 in FIG. The tuner 14 detects a transport stream (TS) from the broadcast signal of the channel currently tuned under the control of the control unit 12 and outputs the detected TS stream to the demultiplexer 15. Then, the demultiplexer 15 separates the data stream from the input TS stream and outputs the data stream to the controller 12. The controller 12 extracts the program guide data from the data stream which is separated from the current demultiplexer 15 and outputs the program guide data to the display unit 18. The display unit 18 displays the program item of the program guide data on the screen as shown in FIG. Program guide data has program items (news, movie, cartoon, drama, etc.) for each channel and time zone, and detailed items (political, economic, social, etc.) of each program item (in case of news). The user first selects a program item by using the key input unit 11. When news is selected from the program items of channel 1, the details of channel 1 news are displayed on the screen. The user again selects the program details (politics) by using the key input unit 11. Then, select the news on channel 2 of the program item and select the details (politics). Then, the controller 12 stores the program identification IDs of the political items corresponding to the news of the two channels selected by the user. The control unit 12 checks whether a stream having program recording IDs reserved for recording is input among the video and audio streams separated by the demultiplexer 15. Thus, if there is a stream with the reserved program identification IDs, the corresponding video and audio streams are stored in the storage unit 13. When the reservation recording is completed in this way, when the user presses the reservation recording playback key using the key input unit 11, the control unit 12 reads the video and audio stream stored in the storage unit 13 to the MPEG signal processing unit 16. Output The MPEG signal processor 16 processes the input video and audio streams so that they can be output. Accordingly, the user views the stationary items of the channel 1 news and the stationary items of the channel 2 news through the speaker 17 and the display unit 18.

As described above, according to the present invention, the user can select desired program items and simultaneously view and record detailed items of each item.
