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

FIG. 1 is a block diagram showing the configuration of a VRC for performing the automatic screen search method of a VR in accordance with the present invention. The remote controller 10 includes a time setting key having a function of setting a screen search time according to the present invention; A normal function key for controlling the operation of the V-Cal is provided, and is configured to transmit a signal corresponding to the pressed key. The remote control receiver 20 is configured to receive a signal transmitted from the remote controller 10, and the controller 30 connected to the remote controller receiver 20 includes a timer micom 31 and a servo / syscon micom ( Servo / Syscon micom) is configured to operate the deck unit 40 according to the signal output from the receiving unit 20 of the remote control, and to display the operation result of the deck unit 40 on the fluorescent display unit 50.

When the operation mode of the deck unit 40 is operated in the playback mode (play mode: PLAY MODE) in the VR according to the present invention configured as described above, when the user wants to watch a screen before or after a predetermined time on the current playback screen, Perform the following operation.

That is, the user presses the fast reverse key (REW key) or the fast forward key (FF key) of the remote controller 10 when the user wants to see a screen before a predetermined time or a screen after a predetermined time while operating in the play mode.

Next, after pressing the time setting key according to the present invention, press a numeric key for inputting a number corresponding to the search time of the desired screen. For example, if you want to see the screen that is played back 30 minutes before or after the current playback screen, press the fast reverse key or the fast forward key, press the time setting key, and then press the number keys on the remote controller 10, [3] [0]. Is to press.

At this time, the remote control receiving unit 20 receives a signal corresponding to the pressed key of the remote control unit 10 and outputs the signal to the control unit 30, the control unit 30 receiving the signal output from the remote control receiving unit 20 Timer microcomputer 31 applies this signal to servo / ciscon microcomputer 32. At this time, when the signal corresponding to the fast forward key or the fast reverse key is input through the timer micom 31, the servo / syscon micom 32 returns the deck unit 40 to the fast reverse speed regeneration mode or the fast forward speed regeneration mode. The operation time of the fast reverse double speed regeneration all or the fast forward double speed regeneration mode is operated for the time input by the time setting key and the numeric keys.

At this time, the CTL (Control) head (not shown) of the deck unit 40 reads the CTL signal recorded on the CTL track of the tape being driven in the high speed reverse speed mode or the high speed forward speed mode, thereby providing a servo / ciscon micom 32 Send to). Then, the servo / ciscon micom 32 counts the CTL signal provided from the CTL head (not shown) and sends it to the timer micom 31, and the timer micom 31 regenerates the regeneration mode (high speed) according to the CTL signal count value. The time of operation in the reverse mode or the fast forward mode) is displayed on the fluorescent display unit 50.

In addition, the timer microcomputer 31 is a deck unit currently driven in a fast playback mode when a CTL signal corresponding to a predetermined time at which a desired screen pressed by a user is reproduced from the CTL head (not shown) of the deck unit 40 is counted. After converting the 40 to the stop mode, the deck unit 40 is driven to operate in the play mode.

FIG. 2 is a flowchart illustrating a process for performing an automatic screen search method of a video cassette recorder according to the present invention, which will be described in detail with reference to the components of VRC shown in FIG.

In a state in which the deck unit 40 is operating in the play mode in step 100, the controller 30 proceeds to step 101 and determines whether there is a key input from the remote controller 10. As a result of the determination, if there is no input key, the flow returns to step 100, and if there is an input key, the control unit 30 proceeds to step 102 and determines whether the input key is a fast forward key.

As a result of the determination, if it is not the fast forward key, the process proceeds to step 111, and if the fast forward key is input, the controller 30 proceeds to step 103, that is, the signal for the fast forward key is provided in the state of being operated in the play mode. The deck unit 40 proceeds to the fast forward double speed regeneration mode (CUE mode), and the process proceeds to step 104 where it is determined whether there is an input of the time setting key.

As a result of the determination, if there is no input of the time setting key, the controller returns. If there is an input of the time setting key, the control unit 30 proceeds to step 105 and after pressing the time setting key, the numeric key, i. It is determined whether there is an input of a numeric key for setting a search time of a desired screen.

As a result of the determination, if there is no input of the numeric key within t seconds, the controller returns. If there is an input of the numeric key, the control unit 30 proceeds to step 106 and converts the deck unit 40 to the stop mode, and then proceeds to step 107. To advance the deck portion 40 to the fast forward mode (FF mode).

Next, the control unit 30 proceeds to step 108 and counts the CTL signal read and output from the CTL head (not shown) of the deck unit 40 to determine whether the predetermined reproduction time set in the numeric keys has elapsed. do. That is, the timer microcomputer 31 of the controller 30 determines whether the time for counting the CTL signal output from the CTL head (not shown) corresponds to the number key input in step 105.

As a result of the determination, if the time detected from the counted CTL signal corresponds to the numeric key, the process proceeds to step 109 to convert the deck unit 40 to the stop mode, and proceeds to step 110 to operate in the play mode.

On the other hand, if the key input in step 102 is not the fast forward key, the controller 30 proceeds to step 111 and determines whether the input key is the fast reverse key. As a result of the determination, if it is not the fast reverse key, the flow proceeds to step 118 to perform a function corresponding to the input key and ends.

In this case, if the input key is the fast reverse key, the controller 30 proceeds to the step 112, and since the signal for the fast reverse key is provided in the play mode, the control unit 30 replays the deck unit 40 at the high speed backward play. Operation mode and proceed to step 113.

In step 113, the controller 30 determines whether there is an input of the time setting key, and returns if there is no input of the time setting key, and if there is an input of the time setting key, the controller 30 proceeds to step 114.

The control unit 30 proceeds to step 114 determines whether there is an input of a numeric key within t seconds, which is a preset time after the time setting key is input in step 113. If it is determined that there is no input of the numeric key within t seconds, if there is no input of the numeric key within t seconds, the control unit 30 proceeds to step 115 and converts the deck unit 40 to the stop mode, and proceeds to step 116. The deck unit 40 proceeds to operate in the fast reverse playback (REW) mode.

Next, the control unit 30 proceeds to step 117 and the time for the CTL counted by counting the CTL signal provided from the CTL head (not shown) of the deck unit 40 is input to the numeric key input in step 114. Determine if it is time. That is, if the time for the CTL signal counted by the CTL head (not shown) is the same as the time for the numeric key input in step 114, the process proceeds to step 109 to perform the operation as described above.

As described above, the VRL screen searching method according to the present invention performs fast forward double speed playback or fast reverse speed double playback when a signal for a fast forward key or a fast reverse key is input during the play mode. When the time setting key and the numeric key for the screen playback time to be viewed are input, the desired screen can be easily searched by executing the fast forward mode or the fast reverse mode for a time corresponding to the input numeric key.
