Method for editing stock in digital broadcasting receiver

According to the present invention, in a recording program editing function of a PVR composite device capable of recording and playing a broadcast signal as a digital signal, when a user has two or more different program IDs in one recorded program, the user edits the recording using a program list. The present invention relates to a recording editing method in a digital broadcasting receiver.

Recently, the terrestrial receiver has become more complicated and various products are released according to the trend of widespread and advanced. Recently, the most popular topic is the personal video recorder (PVR).

 PVR is a personal digital video recording device that records and plays back information on a hard disk. Unlike a VCR that stores video signals on a magnetic tape, a PVR is a new concept of digital recording device that records and plays back information on a hard disk.

It is a next-generation recording device that can record a certain amount of broadcast programs depending on the capacity without a VCR through the hard disk drive built into the set-top box or television body.

When the PVR selects a channel, the signal currently broadcasted on the hard drive is digitally stored and played simultaneously. Therefore, if the stop button is pressed and the play button is pressed again, the stored broadcast signal is played again from the point where it was stopped.

You can also watch the program that's currently being broadcast, play it back in slow motion, or skip the boring part, making it easy to find and edit the part you want.

The recording program editing function of the existing PVR composite device mainly performs recording based on the recording time entered by the program guide or the user directly, and the degree to which these recorded programs can be merged together or selected and saved in several sections in the recording is stored. It provides a simple editing function.

1 is a view showing a conventional recording editing method.

Referring to FIG. 1, while playing a program through a progress bar indicating a playback flow of a program, a user sets a desired section while directly viewing a screen, and then stores or deletes it.

In addition, the time shift function saves the TV broadcast signal as a digital signal in real time on the HDD or other storage media, and enables the user to view the previous broadcast again by searching the front and back. You can also select and save a certain interval.

However, in the conventional art as described above, when viewing or storing time shifted broadcast contents, the user has to find a starting point and an ending point while moving the screen directly through a progress bar or a bookmark.

Accordingly, an object of the present invention is to easily identify program contents for a recorded program to be edited by listing and selecting a program list of the corresponding contents without reproducing and checking the program when editing after time-shifting or recording various types of programs. In addition, the present invention provides a method of editing recordings in a digital broadcast receiver that allows a user to easily and simply edit only a desired program.

Another object of the present invention is to select the editing unit as a program unit to play the storage directly, so that the user does not need to set the editing section while watching, easy to set the section to save and can eliminate the error that other programs are inserted before and after The present invention provides a method for editing a recording in a digital broadcast receiver.

According to an aspect of the present invention to achieve the above objects, if a channel change is made during time shift / recording, a program ID is generated according to the channel change, and a program list is generated and output whenever the program ID is changed. When the program selection information is received from the user, a program corresponding to the program selection information is stored.

Whenever the program ID changes, the program information is read from the PSIP to make a program list.

The user selects a program to be saved from the outputted program list.

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

2 is a block diagram schematically illustrating a configuration of a digital broadcast receiver capable of editing a recording using a list of recorded programs according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the digital broadcast receiver includes an IR receiver 200, a controller 210, a memory 220, a tuner 230, a demodulator 240, a demultiplexer 250, a decoder 260, an MPEG. The encoder 270 includes a PVR processor 280, an HDD 290, a video processor 300, and an output unit 310.

The IR receiver 200 receives the remote control code information selected by the user and transmits it to the controller 210.

The controller 210 analyzes a remote control code transmitted from the IR receiver 200 and transmits remote control code analysis information to a corresponding device.

The memory 220 includes a flash ROM for storing software such as an operating system and a DRAM for storing a virtual screen in a bitmap form that can be represented on an output unit.

The tuner 230 transmits the radio signal transmitted through the antenna to the demodulator 240 according to the analysis information of the remote control code selected by the user, and the demodulator 240 IFs the radio signal transmitted from the tuner. The signal is converted into a signal and transmitted to the demultiplexer 250.

The demultiplexer 250 parses various pieces of information such as audio, video, and other data multiplexed on the signal transmitted from the demodulator 240.

The decoder 260 decodes the audio and video signals and data signals obtained by parsing by the demultiplexer 250 and processes them so that the user can view them.

The MPEG encoder 270 encodes the signal transmitted from the decoder 260 and transmits the encoded signal to the PVR processor 280.

The PVR processor 280 stores the broadcast signal encoded by the MPEG encoder 270 in the HDD 290.

In addition, the PVR processor 280 generates a program ID corresponding to the broadcast program if a channel change or various other programs are broadcast while the time shift is performed on the broadcast program.

Then, whenever the generated program ID is changed, the PVR controller 280 reads the program information from the PSIP, creates a program list, and outputs it through the output unit 310 through the video processor 300.

The PVR processor 280 stores a program corresponding to the program selection information selected by the user in the HDD 290.

The HDD 290 stores a broadcast signal transmitted through the PVR processor 280.

Hereinafter, a program editing method based on time shift in the digital broadcast receiver configured as described above will be described with reference to FIG. 3.
