Description

Recording control method of display device {Method for recording of image display device}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display apparatus, and more particularly, to a recording control method of a display apparatus capable of performing an instant recording function efficiently in a display apparatus having a personal video recording (PVR) function.

Recently, with the spread of digital broadcasting, PVR (Personal Video Recording) or DVR (Digital Video Recording) functions are being applied to display devices.

A personal video recorder (PVR) is a personal digital video recording device that records and plays back information on a hard disk. Unlike VCR (Video Cassette Recorder), which stores video signals on magnetic tape, PVR is a new concept of digital recording device that records and plays back information on hard disk.

A personal video recorder can record a certain amount of broadcast programs, depending on its capacity, without a VCR, via a hard disk drive built into the set-top box or TV body.

The basic function of the PVR is not much different from the existing VCR in that the program stored in the broadcasting station is stored and viewed, but the information is recorded on the hard disk and played in a file playback method such as a computer, and the central processing unit (CPU) ) And a memory chip and a large hard disk containing the operating system and playback software.

On the other hand, when the user sets the scheduled recording using the PVR, the recording start time and the recording end time of the program to be recorded are respectively set. Then, recording of a specific program is performed based on the set recording start time and recording end time.

However, in the case of recording (immediate recording) by using the recording button of the PVR, if the user does not input the recording stop key, since the separate recording end time is not set, continuous recording is performed.

Therefore, if the recording is executed immediately as described above, the recording can be terminated when the user directly inputs the recording end key. If the user forgets the recording, the recording is continuously recorded until the recording is not necessary. There is a problem going on.

According to an embodiment of the present invention, if the display apparatus records a broadcast program currently being received by using the instant recording function, an end time of the ongoing instant recording function can be efficiently set based on the end time of the recording program. do.

In addition, according to an embodiment of the present invention, by automatically deleting the recorded part irrespective of the user's intention, it is possible to increase the efficiency of the storage medium embedded in the display device.

The technical problems to be achieved in the proposed embodiment are not limited to the technical problems mentioned above, and other technical problems not mentioned above are clear to those skilled in the art to which the proposed embodiments belong from the following description. Can be understood.

According to an embodiment of the present disclosure, a method for controlling recording of a display apparatus includes: storing a specific broadcast program when an immediate recording function is selected while receiving a specific broadcast program; Displaying a menu screen inquiring whether to terminate the recording function immediately; And terminating the recording function immediately during the execution based on a user request input on the menu screen.

According to the display device and the recording control method according to the present invention, by prompting the user whether or not to continue recording at the time of the end of the broadcast program recording at the time of recording, to remind the user that the current recording is in progress In addition, by automatically deleting the additional recorded portion irrespective of the user's intention on the basis of the end point of the broadcast program, it is possible to efficiently manage the storage medium.

The proposed embodiment will be described.

To provide a storage unit 140 for storing and a menu screen inquiring whether to continue the recording of the video signal and the audio signal being stored. An on screen display (OSD) processor 150 and a controller 160 for receiving a user's input request through the user input unit 130 and performing overall control of the entire display device accordingly.

Hereinafter, a detailed configuration operation of the display apparatus according to an exemplary embodiment of the present invention configured as described above will be described.

The digital broadcast signal is transmitted in the form of a packetized transport stream by time division multiplexing a video signal, an audio signal, and additional data.

The broadcast receiver 100 receives a broadcast signal transmitted from the outside through an antenna, and tunes a tuner for tuning a broadcast signal having a frequency band corresponding thereto according to a tuning control signal of the controller 160 to be described later. It may include a demodulator for outputting a broadcast signal of the channel in the form of a transport stream through a VSB (Vestigial Sideband) demodulation process and error correction process.

In addition, the broadcast signal received through the broadcast receiver 100 is divided into various additional data defined as a video signal, an audio signal, and PSIP (Program and System Information Protocol) information by a separate demultiplexer (not shown). Output in the form of a stream.

The video data and the audio data separated through the demultiplexer are processed by the broadcast processor 110 and output to the broadcast output unit 120.

In this case, the broadcast processor 110 includes a video processor and an audio processor, and the video processor converts the MPEG-2 decoder and the video data so as to fit the vertical frequency, resolution, aspect ratio, etc. according to the output standard of the video output apparatus. It includes a scaler.

The video output device may be applied to various types of display modules, such as digital light processing (DLP), liquid crystal display (LCD), plasma display panel (PDP), and the like.

The audio processor may include an AC-3 decoder, and the audio output device may be implemented as a speaker.

The user input unit 130 is a means for receiving a request signal from the user and transmitting it to the control unit 160, which is a local key input unit provided at one side of the display apparatus, an infrared receiver unit for receiving an infrared signal input through a remote controller. And a touch screen.

In addition, the additional data according to the PSIP standard separated through the demultiplexer is stored in the storage 140 by the controller 160 to be described later. In this case, the storage 140 may be implemented by an electrically erasable programmable read-only memory (EEPROM) and a hard disk drive (HDD) which is a mass storage medium.

The OSD processing unit 150 generates UI data for setting whether to terminate an immediate recording function currently being performed under the control of the controller 160 to be described later, which may be implemented by an OSD (On Screen Display) generating IC.

The controller 160 controls the overall operation of the display apparatus.

That is, if the recording function request is immediately input through the user input unit 130 while the received broadcast signal is being output, the control unit 160 receives the broadcast signal received through the broadcast receiving unit 100. To be stored at 140.

At this time, if the broadcast signal storage according to the instant recording function request is performed as described above, the broadcast signal received through the broadcast receiving unit 100 is continuously stored until the user inputs a separate immediate recording function termination request. Stored at 140.

Therefore, when the immediate recording function is performed, the controller 160 determines an expected end time of the instant recording function and determines whether to terminate the current instant recording function based on the estimated end time.

That is, when the immediate recording function is performed as described above, the purpose is to record a broadcast program that has already started broadcasting.

Therefore, when the immediate recording function is performed, the controller 160 checks the broadcast end time of the currently broadcast program, and identifies the confirmation broadcast end time as an expected end time of the instant recording function. Herein, the controller 160 determines whether to perform a continuous immediate recording function before the broadcast program ends, so that the immediate recording function is performed a specific time before a broadcast end time for the broadcast program arrives. It can also be thought of as the expected end of.

That is, the controller 160 analyzes the program specific information protocol (PSIP) information included in the received broadcast signal to determine the expected end time of the instant recording function. Here, the PSIP is a data protocol transmitted together with a digital broadcast signal, which is a broadcast signal transmitted from a digital broadcast station. The PSIP identifies important information about a broadcast station transmitting a digital broadcast and a program currently being broadcast in a display apparatus according to an embodiment of the present invention. To help.

Accordingly, when the controller 160 detects the expected end time of the instant recording function as described above, the controller 160 waits until the determined expected end time, and accordingly, when the expected end time arrives, the instant recording function is currently performed. And a message asking whether to continue the recording function as soon as it is being performed. In addition, as described above, the controller 160 may display the menu screen before a predetermined time on the basis of the end time of the broadcast program.

In addition, the controller 160 provides a program currently broadcast and program information scheduled for the next broadcast through the menu screen in order to more easily determine whether the immediate recording function is continuously performed.

As the message is displayed, the controller 160 terminates the instant recording function currently being executed or continuously performs the instant recording function according to the request input from the user.

Accordingly, the user can recognize that the immediate recording function is currently performed, and accordingly, the user can easily input the stop command of the immediate recording function.

In this case, after the message is displayed, if the separate request is not input from the user for a predetermined time, the controller 160 performs the following operation.

The first is to continuously display the message at regular intervals.

That is, if there is no user request input according to the displayed message at the present time, the controller 160 checks a certain period, and accordingly, displays the message again after a predetermined time.

Second, if the separate request is not input, it is immediately determined as a request for termination of the recording function.

In other words, the user is likely to immediately set the recording function, to see other tasks, or to go out.

Therefore, if there is no user request input according to the displayed message at this time, the controller 160 terminates the recording function immediately and stops storing the received broadcast signal.

In addition, at this time, the storage unit 140 may have a portion stored regardless of the user intention.

That is, the received broadcast signal is continuously stored from the estimated end time point to the input time point of the user request corresponding to the end of the immediate recording function.

Therefore, when there is a request to end the recording function immediately, the controller 160 checks the additionally stored part irrespective of the user's intention, and accordingly displays a message asking whether to delete the checked part.

The controller 160 deletes or maintains the additionally stored part based on a user request input on the displayed message.

For example, when the end time of the broadcast program being broadcast is PM 08:00 when the user selects the instant recording function and the time when the request for terminating the instant recording function is input is PM 08:05, the storage unit. In 140, a portion of about 5 minutes is recorded regardless of the user's intention.

Accordingly, the controller 160 displays the message as described above, and deletes the additionally recorded five-minute recording portion from the storage unit 140 to efficiently use the capacity of the storage unit 140. Make sure

In addition, the controller 160 provides a list of all the broadcast programs stored through the instant recording function selection, and accordingly deletes only the broadcast program selected by the user or deletes the remaining broadcast programs except the selected broadcast program. do. That is, the time information of each broadcast program is stored in the storage unit 140, and accordingly, the controller 160 deletes the pre-stored broadcast program or maintains continuous storage according to a user request.
