PAPR's time-shift playback device and method {APPARATUS AND METHOD FOR PLAYING TIME-SHIFT DECISION TIME OF PERSONAL VIDEO RECORDER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to broadcast playback technology using a personal video recorder (PVR), and more particularly, to an apparatus and method for specifying a time shift time designation for a PVR suitable for outputting a playback screen based on a time designation during broadcast playback using a time shift.

In general, unlike a VCR that stores video signals on magnetic tape, a PVR is a digital broadcasting recording device that records and plays back information on a hard disk. The PVR can be set according to its capacity without a VCR through a hard disk drive built into a set-top box or television body. You can record hours of broadcast programs.

The basic function of the PVR is that it is not different from the existing VCR in that it can store and view a program exported from a broadcasting station. However, the PVR records information on a hard disk and plays it in a file playback method such as a computer. It contains a central processing unit (CPU), a memory chip containing an operating system and playback software, and a large capacity hard disk. In addition, the PVR is composed of a television tuner, storage and playback software, a modem, a hard drive, and the like. The PVR converts a television program into a digital signal and stores and plays the data on the hard disk. Depending on the capacity of the hard disk, more than 30 hours of television programs can be stored and many programs can be recorded at the same time.

Accordingly, when a user selects a broadcast channel through a remote controller, a signal currently broadcasted on the hard drive is automatically stored digitally and played simultaneously. Therefore, the program being broadcasted is recorded. At this time, 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. In addition, the program can be viewed again or played in slow motion, and the boring part can be skipped, so that the function of finding or editing the desired part can be implemented.

In addition, there is a time shift function as a function of the PVR. For example, if you are going out for a while or watching a meal while watching a broadcast, press the Pause button on the remote control and the received broadcast will be saved on the hard disk. There is an advantage that you can watch from the scene after the saved screen.

Referring to FIG. 1, the PVR is a video signal processor for processing a video signal and an audio signal of a tuner 100 for tuning a desired channel from a broadcast signal transmitted from a broadcast station and a broadcast signal selected from the tuner 100 as a digital signal. 102 and the audio signal processor 104, an encoder 106 for converting the video signal and the audio signal passed through the video signal processor 102 and the audio signal processor 104 into a digital stream form, and each component of the PVR. A control unit 108 that controls elements and performs various time shift functions based on a signal input through the input unit 112, a storage unit 110, and a storage unit which stores a digital stream output from the encoder 106. A decoder 114 for reconstructing and outputting a digital stream video signal and an audio signal stored in 110, and a video / audio signal for outputting a digital video / audio signal output from the decoder 114. And a ryeokbu 116.

Here, the input unit 112 directly receives a signal through a button attached to the PVR or a button of a remote controller for controlling the PVR. At this time, the button to be input is a function button + number button, in one embodiment, when the first function button + number button is input, the number button is input as time information, received through the input unit 112 The controller 108 performs a position search by the time of the recorded time point of the time-shifted broadcast program and outputs an image and audio thereof. As another embodiment, when the second function button + number button is input, As the button is input at the reproduction speed, the controller 108 reproduces the reproduction speed of the time shifted broadcast program at the same speed as the input number button.

Specifically, when a user presses a function button attached to a remote controller or PVR, the controller 108 which receives the input through the input unit 112 generates OSD (On screen display) information to receive numeric information for performing the corresponding function. It is provided to the user through the display unit connected to the PVR. When the user inputs a numeric button, the user can check this. The input numeric button is transmitted to the controller 108 to perform a corresponding function using the numeric information input from the controller 108.

2 is a flowchart illustrating a program control procedure using a time shift function in a PVR according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in operation 200, the PVR is loaded while the PVR is turned on, and decoding of a preset broadcast channel is performed to output video and audio to a user. In this case, when the user selects a broadcast channel in step 202, a program of the selected broadcast channel is provided.

Thus, when the user inputs a specific time shift function button as a first function button directly on the remote control button input or the PVR in step 204, the time shift function is performed, and through this, the program currently being watched by the user is Through the time shift function, it is possible to turn broadcasting from the time when the time shift function is started.

Thereafter, in step 206, the user simultaneously inputs the first function button and the number button through the input unit mounted on the PVR or the keypad of the remote controller to transmit a signal to the input unit 112 of the PVR, and in step 208, the PVR after the first function button. Check the storage time by inputting the numeric button 4 digits that are sequentially input into the digits, that is, two digits of the hour and two digits of the minute, and search for the location of the time shifted or stored time of the broadcast program. To output the broadcast program signal of the corresponding position.

For example, the user may leave the room for a while while watching a soccer relay and perform a time shift function. After that, a goal scene occurs while away, so that the user searches for the goal scene in the time-shifted image. However, one day searches are performed in the time-shifted image. If it is 8 o'clock and the soccer game with the goal was 40 minutes in the first half, the user enters "2000" with the number buttons along with the function buttons on the remote control.

Accordingly, the PVR determines that the 2000 input after the function button is 20:00, and outputs the broadcast video recorded at 20:00 among the time shifted images. In addition, when the user returns to the seat for about 45 minutes in the first half, that is, at 8:05 pm, the PVR is broadcasted at 20:00 by inputting "2000" with the number buttons together with the first function button with the remote control. The image will be output.

3 is a flowchart illustrating a program control procedure using a time shift function in a PVR according to another exemplary embodiment of the present invention.

Referring to FIG. 3, in operation 300, the PVR is loaded while the power is turned on, and decoding of a preset broadcast channel is performed to output video and audio to a user. In this case, when the user selects a broadcast channel in step 302, a program of the selected broadcast channel is provided.

Thus, when the user inputs a remote control button input or a function button directly to the PVR in step 304, the time shift function is performed, and the time shift function is performed through a time shift function for a program currently being watched by the user. It is possible to watch the broadcast from the beginning.

In step 306, when the second function button and the number button are simultaneously input through the input unit mounted on the PVR or the keypad of the remote controller, the signal is sent to the input unit 112 of the PVR. The numeric button input as is a single digit or two digit number and plays a time shifted broadcast program at a playback speed corresponding to the numeric button.

At this time, the program currently broadcast through the PIP (Picture in Picture) function is viewed through the main screen, and the time-shifted broadcast program is viewed through the sub-screen at a set playback speed.

For example, if a user performs a time shift while watching a soccer game from 7:50 pm to 8:00 pm while the user is away, the user returns to 8:00 pm to watch the existing soccer broadcast on the main screen. At the same time, you can watch the time-shifted soccer relay on the sub-screen. At this time, the main screen sub-screen can be changed by the user's selection, and if the user presses the number button 2 together with the second function button on the remote control while watching the time-shifted football relay, the playback speed is twice as fast. .

In this case, when the time shifted soccer relay broadcast, which is played at twice the speed, reaches the soccer relay broadcast currently being broadcast, in step 310, if it matches the current received signal in step 310, the process proceeds to step 312. The shifted program is ended, and only the football relay broadcast currently being broadcast is output.

As described above, the time-shifted broadcast can be precisely searched through FIGS. 2 to 3, and the broadcast speed can be easily checked through adjustment of the playback speed. It can also be possible.

As described above, the present invention is to set the time designation and playback speed through the PVR input unit or the remote control to perform the location search and playback of the broadcast program, and to designate the broadcast program playback time during the broadcast playback using the time shift function of the PVR. When the broadcast program screen stored at the corresponding time is searched and outputted, the time shifted broadcast program is played at the speed set by the user, or the broadcast program played by the time shift reaches the reception signal of the currently received broadcast program, Ends the time shifted broadcast program and outputs only the real-time broadcast program.
