Description

How to Play a Recording Program on a Video Cassette Recorder

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video cassette recorder (hereinafter abbreviated as BC), and more particularly to a method of storing and playing back a recorded program.

V-Cal is a device that selectively magnetizes a magnetic video tape with a head to record video and audio signals or to read video and audio signals recorded on the video tape.

In particular, the recording mode of V-CAL is a very useful function of recording a program desired by the user among the broadcast signals flowing through the antenna, or recording or editing the contents of another tape by connecting to an external input terminal.

However, when a plurality of programs are sequentially recorded on one video tape by this recording method, there is a problem that it is not easy to select and play a desired program.

In other words, in order to play and watch one of a plurality of recorded programs, the user has to search for a desired program by operating V-Cal in a fast forward and a fast rewind mode.

Therefore, since this method requires a considerable time for the user to search and start the program, a search method using a Video Index Search System (VISS) signal has been proposed.

In the method of using a vis signal, a vis signal is recorded in a video tape control track of a portion where recording is started, and at the time of vis searching, recording is started by driving in a playback mode for a predetermined time, for example, 5 seconds only in a section where the vis signal is recorded. One section can be easily searched.

However, in the conventional method using the vis signal as described above, when a plurality of reserved recording programs exist on one tape, it takes a long time to search for a desired program.

Accordingly, the present invention has been made to solve the above-described problem, and the present invention provides a method for reproducing a recorded program of V-CAL that enables a user to easily search for a desired program when a plurality of programs are continuously recorded on one video tape. The purpose is to provide.

In order to achieve the above object, the present invention provides a method of reproducing a broadcast program recorded in a video cassette recorder which records a vis signal at the time of recording a broadcast program and increases the value of the vis count coefficient by one. Determining; Displaying recorded reproduction numbers when the reproduction position selection mode is set; If one of the displayed reproduction numbers is selected, comparing the stored vis count coefficient value with the current vis count coefficient value corresponding to the selected reproduction number; Increasing / decreasing the current vis count count value each time a vis signal is detected from the video tape such that the vis count count value is equal to the current vis count count value, and moving the video tape forward and backward; A method of reproducing a recorded program of a video cassette recorder comprising the step of reproducing a signal recorded on a video tape when the stored bit count value is equal to the current bit count value.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings.

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

Fig. 1 is a schematic block diagram of a VRC for carrying out a method of reproducing a recorded program according to the present invention. As shown in Fig. 1, a tuner 10, a recording processing system 20 and a reproduction processing system 30, and a deck 40 are shown. , Microcomputer 50, key matrix 60, and OSD 70.

Here, the tuner 10 receives and outputs a broadcast signal of a predetermined channel according to the control L1 of the microcomputer 50, and the recording processing system 20 controls the tuner 10 under the control L2 of the microcomputer 50. The video and audio signals applied from the recording process are applied to the deck 40, and the deck 40 records the video signal of the recording processing system 20 on the video tape according to the control L4 of the microcomputer 50. And a signal of a video tape is read and applied to the reproduction processing system 30.

That is, the deck 40 is provided with a capstan motor and head drum which are in charge of running the video tape, and a video and audio head for recording and reading out video and audio signals, respectively. In addition, a deck 40 has a control head for recording and reading control signals in a control track of a video tape, and records a predetermined vis signal as a control head under control L4 of the microcomputer 50, This bis signal is configured to be read.

Meanwhile, the reproduction processing system 30 reproduces and outputs the video and audio signals detected by the deck, and the OSD 70 reproduces a predetermined OSD signal under the control L5 of the microcomputer 50. The signal is mixed with the signal and applied to the TV.

In addition, the microcomputer 50 is configured to control the above-described components in response to a key selected by the user, ie, pressed, among various function keys of the key matrix 60.

2 and 3 show flowcharts of programs stored in the microcomputer 50 for carrying out the present invention.

First, in order to disclose the present invention, the microcomputer 50 of the present invention should store recording information even after recording. That is, the conventional microcomputer 50 automatically deletes the recording information recorded, but the microcomputer 50 of the present invention should store the recording information recorded. In this case, the recording information can be erased by the user's selection, and this technique can be easily implemented by those skilled in the art, which is not described herein.

In addition, the microcomputer 50 of the present invention should record the vis signal when the storage key signal is applied in the recording mode of V-Cal as shown in FIG. 2 and store the order in which the vis signal is recorded (step 100). ), (Step 102).

Then, the microcomputer 50 causes the deck 40 to record the broadcast signal of the tuner 10 on the video tape, but records the vis signal on the control track of the video tape and increases the value of the vis count coefficient by one. The bit count value of the recording information is stored (step 104) and (step 106).

At this time, the microcomputer 50 controls the OSD 70 to display the recording information according to the count coefficient value storage described above as a OSD signal for a predetermined time (for example, 2 seconds) as shown in FIG. 4A (step 108). ). That is, by displaying the currently stored recording position and the program sequence number on the TV screen, it is possible to easily select a reproduction number to be described later.

The microcomputer 50 ends the predetermined recording process after recording the broadcast signal of the tuner 10 on the video tape until the stop key signal is applied from the key matrix 60.

That is, as described above, the microcomputer 50 of the present invention records the vis signal on the video tape when recording starts, and increases the value of the vis count by one.

FIG. 3 is a flowchart of the method of the present invention, which enables playback of a program recorded by the process of FIG. 2 according to a user's selection.

As shown, the microcomputer 50 of the present invention determines whether the playback position selection key of the key matrix 60 is pressed in step 200.

When the playback position selection key is pressed, the microcomputer 50 proceeds to step 202 to control the OSD 70 to display the recorded recording information as the OSD signal for a predetermined time as shown in FIG. 4B. After displaying the OSD signal, the microcomputer 50 determines whether a signal for selecting one of the recording information is applied within a predetermined time (for example, 5 seconds) (step 204), and the signal is applied (step 206). When done, step 208 is reached. As such, a method of selecting one of the recording information may be various methods using a number key corresponding to the number added to the recording information, or using a cursor or the like, as shown in FIG. 4B. Those skilled in the art will readily know.

In step 208, the microcomputer 50 compares the current vis count count value with the stored vis count count value of the set recording program. 40 is driven in fast reverse mode (step 212), and when small (step 214), deck 40 is driven in fast forward mode (step 216).

Then, the microcomputer 50 decreases / increases by one the vis count coefficient value each time a vis signal is detected from the video tape.

Then, the microcomputer 50 causes the deck 40 to run in the reproduction mode when the reduced / increased vis count coefficient value is equal to the vis count coefficient value of the recorded program stored in steps 104 and 106, and the reproduction processing system ( 30 is to control to reproduce and output the signal read out from the deck 40 (step 218).

That is, in the present invention, when the programs according to the plurality of recording information are sequentially recorded on one video tape, the video tape is moved forward / backward mode such that the non-count count value and the present non-count count value of the recorded program selected by the user are the same. In this case, the recorded program selected by the user can be played from the recorded position.

As described above, the present invention has the effect that the desired program can be easily searched among the recorded programs.
