The present invention relates to a digital broadcasting receiver, and in particular, when performing reservation recording in a digital broadcasting receiver equipped with a PVR function, comparing the same programs provided through a plurality of program providers (PPs). The present invention relates to a method of selecting and recording a program meeting a condition set by a user.

A digital broadcasting receiver, commonly called a set top box, is a device configured with a TV receiver to receive various TV image data of multiple channels transmitted through a network or satellite, and transmitted through a network or satellite. Receive the digital broadcasting data compressed by the MPEG-2 method, decompress the compressed data, decode the encoded data, and convert the encoded data into a standard NTSC signal so that it can be displayed on a TV receiver.

That is, the digital broadcast receiver receives a bit-stream type digital broadcast signal transmitted by a broadcasting station and broadcasts a channel selected from the broadcast signals received by transport demux. It is configured to extract the signal, decode the extracted broadcast signal in a moving picture experts group (MPEG) -2 scheme, and display the extracted broadcast signal.

At this time, the MPEG-2 method is an international standard for transmitting video and various data for next generation television broadcasting, satellite broadcasting, and the like. In MPEG-2, various signals for moving picture, sound, and other additional service information are programmed. It is prescribed to packetize into a bit stream such as stream (PS) and a transport stream (TS). In the multimedia communication using MPEG-2, a plurality of pieces of information in the TS stream are loaded on the transmitting side. On the other hand, the receiving side extracts information carried by parsing from a TS stream including a plurality of pieces of information, and decodes it.

Meanwhile, the TS stream includes not only a broadcast program for digital TV broadcasting but also electronic program guide information having program guide information for each channel and time zone for the broadcast program. It is also possible to select a broadcast program through information and make a reservation recording in advance. As the PVR function is recently installed in a digital broadcast receiver, the broadcast program data is recorded in a large capacity HDD such as a PVR.

However, in the conventional digital broadcasting receiver equipped with a PVR, a program provided from a channel designated by a user when recording a reservation recording using the EPG as described above is recorded regardless of the quality of a program received from the channel.

Therefore, there is a problem in that even if a program to be reserved by the user is provided with a different quality by a plurality of program providers, a program received from a channel designated by the user is recorded. That is, for example, when a reserved broadcast program is a specific movie, there may be a plurality of channels providing the same movie content. Even if the same movie is used, the propensity or advertisement time of the advertisement inserted in the middle of the movie may be different depending on program providers. Although it may be different, conventionally, there is no method in which the user can preselect the above items and set the scheduled recording to the desired program.

Accordingly, an object of the present invention is to provide a method of selecting and recording a program meeting a condition set by a user by comparing the same programs provided through a plurality of program providers when performing a scheduled recording in a digital broadcasting receiver equipped with a PVR function. .

The present invention for achieving the above object is a reservation recording method of a broadcast program in a digital broadcast receiver equipped with a PVR function, (a) proceeds to the reservation recording mode in accordance with the reservation recording request input from the user to the reservation recording program information Waiting for an input, (b) searching for channels of program providers providing a corresponding program using PSIP information according to the reserved recording program information input from the user, and (c) the reserved recording requested program Selecting a channel corresponding to the quality condition of the program set by the user from among the channels providing the program; and (d) performing the scheduled recording of the program from the selected channel when the scheduled recording time is reached. Characterized in that it comprises a step.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment according to the present invention.

1 is a schematic block diagram of a digital broadcast receiver equipped with a PVR function to which an embodiment of the present invention is applied.

Referring to FIG. 1, first, the key input unit 118 and the remote controller 126 generate a key data signal according to a user's key operation and apply the generated key data signal to a micom 116. The memory unit 120 stores an operation program for operating the digital television receiver, and stores and outputs various program information output from the tuner unit 100 under the control of the microcomputer 116.

The tuner 100 tunes and receives a bit stream of a channel corresponding to the tuning control signal of the microcomputer 116 among the bit streams received from the terrestrial wave or satellite. The channel decoder 102 decodes the signal selected from the tuner unit 100 in a VSB, QPSK, QAM, or the like manner according to a transmission method, and applies the demultiplexed signal to the demultiplexer 104.

The demultiplexer 104 receives the digital stream decoded by the channel decoder 102, divides the video stream into video, audio, and additional information streams, and applies the decoded video stream to the MPEG-2 decoder 106. Then, the MPEG decoder 106 separates and decodes the broadcast signal provided from the demultiplexer 104 into an audio signal and a video signal, and then performs a predetermined signal processing process through the video / audio processing units 108 and 110 to display the TV receiver display unit ( 112) to be displayed on the screen.

The video processor 108 receives the video signal decoded and outputted from the MPEG-2 decoder 106 and converts the video signal into a displayable image signal on the screen of the display 112 of the TV receiver such as a CRT, PDP, LCD, etc. The audio processor 110 receives the audio signal decoded and output from the MPEG-2 decoder 106 and reproduces the audio signal through the audio output unit such as the speaker 114. The IR receiver 124 receives an operation command of a remote controller operated by a user and applies it to the microcomputer.

The microcomputer 116 controls the overall operation of each part of the digital broadcast receiver according to the operation program stored in the memory unit 120, and the remote controller 126 input from the key data signal from the key input unit 118 and the IR receiver 124. According to the key data from the control signal for generating a corresponding function is generated and applied to the function unit. That is, for example, the tuner 100 provides a tuning control signal for tuning a broadcast channel selected by a user, and generates a decoding control signal for decoding the tuned broadcast signal.

In addition, the microcomputer 116 broadcasts a corresponding program through a broadcast guide function (PSIP: program and system information protocol) provided by a digital broadcast receiver when a reserved recording request program from a user is designated according to an embodiment of the present invention. After searching for the channels, the program provider's channel that meets the channel quality condition set by the user is examined to reserve and record a program provided from the corresponding channel. In this case, the channel quality refers to a program providing form such as advertisement insertion time or type of advertisement for broadcasting the same program in each channel among a plurality of channels that provide a broadcast program that a user wants to reserve. In operation 116, a channel corresponding to a time or type of an advertisement set by the user is checked through the PSIP information and set as a reserved recording channel, and the corresponding program is stored in the hard disk drive (HDD) 122.

FIG. 2 compares the same program of a plurality of channels provided through a plurality of program providers during reservation recording in a digital broadcasting receiver equipped with a PVR function according to an embodiment of the present invention to select and record a program meeting a condition set by a user. The operation control flow is shown. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when a user wants to perform a reserved recording for a specific broadcast program received through a digital broadcast receiver, the user executes the reserved recording menu using the key input unit 118 or the remote controller 126.

Then, the microcomputer 116 of the digital broadcasting receiver receives the key input for the reservation recording from the user in step S200, and proceeds to step S202 to display a menu screen for the reservation recording and the user wants to make a reservation recording. Allows you to set up a broadcast program.

Accordingly, the user sets a reserved recording program of a desired channel in the reserved recording menu screen displayed on the digital broadcasting receiver display unit 112. In this case, the user does not simply select a channel for providing a desired broadcast program, but inputs only a desired broadcast program name, and sets the quality of the corresponding program. As described above, the quality refers to a program providing form such as advertisement insertion time or type of advertisement for broadcasting the same program in each channel among a plurality of channels providing a broadcast program that the user wants to reserve. If the program is a specific movie, for example, each channel that provides the movie inserts an advertisement during a movie broadcast, and the user sets the advertisement time or the type of advertisement inserted during the movie program according to his or her preferred form. .

Then, the microcomputer 116 receives the reserved recording requested program name input by the user and the quality condition for the corresponding program in step S204, and then searches for PSIP information in step S206 and requests the reserved recording by the user. Search for channels of program providers that provide programmed programs.

In operation S208, the microcomputer 116 selects a channel that provides a program that matches the time or type of advertisement set by the user, among channels of program providers that provide the program requested for recording by the user.

Thereafter, the microcomputer 116 checks whether the broadcast time of the program requested by the user in the selected channel has reached the broadcast time in step S210 and proceeds to step S212 when the broadcast time of the corresponding program is reached. Schedule recording for the program is performed and stored in the HDD (Hard Disk Drive) 122.

As described above, in the present invention, when performing a reserved recording in the digital broadcasting receiver, when the user sets a program name and quality condition of the corresponding program, the digital broadcasting receiver provides the program requested by the user for the reserved recording. After searching the channels of program providers, select the channel that provides the program that meets the quality conditions such as the time and type of advertisement set by the user, and reserve the program of the channel that meets the conditions set by the user. This is further enhanced.
