In the broadcast recording of the television and broadcast receiver according to the related art, the reserved recording is performed by inputting the G-code directly to the VCR through the newspaper or the television program guide book for the reservation recording of the broadcast program. However, recently, digital broadcasting has become full-fledged, and it has become very difficult to find broadcasting programs as the multi-channel age has arrived. Therefore, by downloading broadcast programming data called an electronic program guide (EPG) together with a broadcast signal from a broadcast station and displaying electronic program guide information on a television screen through a broadcast receiver (STB: Set Top Box) Can more conveniently search for a broadcast program or perform scheduled recording.

A reservation recording system of a broadcast program according to the related art includes a broadcast receiver capable of receiving a digital broadcast, a television displaying a received digital broadcast on the screen, and a broadcast program recording / A VCR, and a remote controller for controlling the respective devices. The operation of the reservation recording system of the broadcast program according to the related art is as follows. First, the program information is downloaded in a state in which the television and the broadcast receiver are turned on, and temporarily stored in an OSD (On Screen Display) memory of the television. Thereafter, the user can directly search for or select a program by displaying the stored program information on a television screen. At this time, when a reserved recording is performed for a specific broadcast program, when the user presses the reserved recording button of the remote controller, the reserved recording command signal is transmitted to the remote controller receiving module of the recording device (VCR) by the control signal of the remote controller. Therefore, the reserved recording information can be stored in the internal memory of the recording device.

In the information of the electronic program guide displayed on the television screen, broadcast channel information, broadcast time information, and broadcast program names for each channel and time are displayed in the form of a list. Accordingly, the user confirms the electronic program guide information on the television screen, selects the desired broadcast program information according to the broadcast start time, the end time, and the program summary information, and transmits the corresponding broadcast program received through the broadcast channel Or perform reservation recording through the recording device with reference to the broadcast program information. Meanwhile, in order to search for broadcast program information and the like, a user may use an integrated remote controller that simultaneously controls each device (here, a digital broadcast receiver, a television, and a VCR) or a digital broadcast receiver It is possible to perform channel search through the television screen on the electronic program guide information provided by the user. However, in order to perform search and reservation recording of the electronic program guide information, the user must operate the remote controller with the power of the digital broadcasting receiver and the television turned on at all times. That is, when either the broadcast receiver or the television is turned off, it is impossible to search for broadcast program information such as an electronic program guide or to perform scheduled recording or the like. In addition, since the broadcasting receiver and the recording device must be powered on when the reserved recording of the broadcast program is performed, unnecessary power is consumed and the broadcast program must be downloaded again through the broadcast receiver every time the reserved recording is performed There was an inconvenience. Further, in order to retrieve the program information, the user must turn on the power of the broadcast receiver, download the program data, and directly check the downloaded program data on the television screen. Therefore, it is impossible to record a broadcast program through a recording device in a home in a remote place where a broadcast receiver and a television are not provided. Therefore, it is a problem of the related art that the TV and the broadcasting receiver (STB) are operated only when the power is turned on, so that the viewer can not record the broadcasting before the power is turned on, It is necessary to improve the problem of not being able to watch the first half of the already broadcasted broadcast.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flowchart illustrating a retrospective time-shift personal video recorder (PVR) method of a television and a broadcast receiver according to an embodiment of the present invention.

A personal video recorder (PVR) method of a television and a broadcast receiver may include a step 110 of controlling the user to set a desired recording time and a plurality of channels, a step 110 of turning on and off the power of the television and the broadcast receiver (120) receiving and decoding the plurality of channel broadcasts according to a set recording time and a plurality of channels, and storing the decoded broadcast in a PVR storage unit (130).

In the time-based PVR scheme according to the related art, when the television and the broadcast receiver are powered on, recording can be performed on broadcasts currently being received. Therefore, it is impossible to record the previous broadcast. In the present invention, recording is continuously performed for a predetermined time and a plurality of channels designated by the user even when the power of the television and the broadcast receiver is turned off so that the broadcast can be recorded before the viewer turns on the television and the broadcast receiver . Accordingly, the partial power source may be applied to receive a plurality of channel broadcasts regardless of the on-off state of the broadcast receiver power according to the embodiment of the present invention.

In step 110, the user can control to set a desired recording time and a plurality of channels. At this time, when the power of the television and the broadcast receiver is in the off state, the user can control to set a desired recording time and a plurality of channels through the user interface unit. Since the partial power source is applied to receive a plurality of channel broadcasts regardless of the on-off state of the television and the broadcast receiver power source, the television and broadcast receiver according to the embodiment of the present invention is different from the prior art The recording can be performed for a plurality of channels by a specific time before the key is set before the user turns on the power regardless of whether the power is turned on or off.

In step 120, it is possible to receive and decode a plurality of channel broadcasts according to a specific recording time and a plurality of channels before a time point at which the set screen is pressed regardless of whether the power of the television and the broadcast receiver is on- have. The control unit of the proposed invention can provide the recording time and the plurality of channel information set in the broadcast channel tuner by checking the recording time and the plurality of channels set by the user. The broadcast channel tuner can receive a plurality of channel broadcasts designated by the user according to the set recording time and the plurality of channel information received from the control unit. The plurality of channel broadcasts thus received can be transmitted to the audio and video decoders. The audio and video decoders may decode a plurality of channel broadcasts received from the tuner and transmit them to the PVR storage unit.

In step 130, the decoded broadcast may be stored in the PVR storage. The PVR storage unit including the memory and the hard disk may store or permanently store a plurality of channel broadcasts received from the audio and video decoders for a preset time. For example, when the television and the broadcast receiver are turned off during a specific recording time before the user touches the desired screen, a plurality of channel broadcasts can be received and stored during the set recording time until the power of the television and the broadcast receiver is turned on have. Thereafter, when the user selects one of the plurality of channels and the power of the television and broadcast receiver changes from the off state to the on state, the time shift window of the selected channel stops moving and the power of the television and broadcast receiver is turned on the time shift window until the state is changed to the on state can be stored. Then, the time shift window of the selected channel can start a new window from the time when the state is changed to the on state. On the other hand, the time shift window of the remaining channels not selected by the user among the plurality of channels can be continuously stored by moving the time shift window. In this way, the decoded broadcast can be stored or permanently stored for a preset time. If the stored broadcast is deleted in this way, it can be deleted by time unit or program unit. The retrospective time-shift PVR operation proposed with reference to FIGS. 2 and 3 will be described in more detail.

FIG. 2 is a diagram for explaining a retrospective time-shift PVR operation when the power of the television and broadcast receiver is off in accordance with an embodiment of the present invention.

Referring to FIG. 2, it is possible to confirm the movement of the time shift window according to the recording time set by the user and a plurality of channels when the power of the television and the broadcasting receiver is off. At this time, the user can set a desired recording time and a plurality of channels. A plurality of channel broadcasts can be received and decoded according to the set recording time and a plurality of channels, and the decoded broadcast can be stored in the PVR storage unit. For example, the set plurality of channels 220 of FIG. 2 may be Ch6, Ch7, Ch11, ..., ChN. In the embodiment of FIG. 2, the time shift window can be set to four hours (210). The time shift windows 221, 222, 223,..., And 224 of the plurality of channels may move during the recording time set by the user and store a plurality of channel broadcasts. At this time, the non-retroactive time shift window 230 may be broadcast at a time before the time shift window set to 4 hours. When the power of the television and the broadcasting receiver is off, the time shift window 240, which is continuously moved without the screen being turned on, may store a plurality of channel broadcasts during the set recording time. In other words, the television and broadcast receiver according to the embodiment of the present invention can record (or record) a plurality of channels during the set recording time before the user turns on the power of the broadcast receiver, regardless of whether the power is turned on or off .

FIG. 3 is a diagram for explaining a retrospective time-shift PVR operation when the power of the television and broadcast receiver is changed from an off state to an on state according to an embodiment of the present invention.

3, when a user selects one channel among a plurality of channels and the power of the television and broadcast receiver is changed from off to on, The movement of the time shift window can be confirmed. When the power of the television and broadcast receiver changes from off to on during the retrace time shift PVR operation according to the user-set recording time and a plurality of channels, the movement of the time shift window of the selected channel is performed And can store a time shift window until the power of the television and broadcast receiver is turned on. The time shift window of the selected channel can start a new window from the time when the power of the television and the broadcast receiver is turned on. On the other hand, the time shift window of the remaining channels not selected by the user among the plurality of channels can be continuously stored by moving the time shift window. For example, the set plurality of channels 320 may be Ch6, Ch7, Ch11, ..., ChN. In the embodiment of FIG. 3, the time shift window can be set to four hours (310). The time shift windows 321, 322, 323,..., And 324 of the plurality of channels may move during the recording time set by the user and store a plurality of channel broadcasts. At this time, the time-shift window 330 which is not retrospectively stored may be the broadcast of the time shift window previous time set to 4 hours. It is assumed that the viewer turns on the screen and selects Ch N at 22:00 (311) during the movement of the time shift window 340. Then, the time shift window 324 of the selected channel Ch N stops storing and can retrospectively store the timesheet window 325 until the time when the television and the broadcast receiver are turned on (step 311). The time shift window of the selected channel Ch N can start a new window 326 from a point in time when the power of the television and broadcast receiver is turned on (311). On the other hand, among the plurality of channels, the time-shift window 340 in which the user does not select and continues to move moves the time-shift windows 321 and 322 of the remaining channels except for the time-shift window 324 of the selected channel Ch N among the plurality of channels , 323, and can be stored while moving the time shift window continuously.
