Description

How to play the rank of video cassette recorder

The present invention relates to a video cassette recorder (hereinafter referred to as a VCR), and more particularly, to a ranking reproduction method of a VCR that enables to specify a playback order of a plurality of reserved recorded programs.

The VCR is a device that selectively magnetizes a video tape, which is a magnetic material, to a head to record video and audio signals or to read video and audio signals recorded on a video tape to the head.

In particular, such a VCR has a built-in microcomputer for controlling the driving of the VCR therein, and thus, reservation recording using the microcomputer function is possible. That is, when a user inputs reservation information on a recording date, time, recording channel, and the like, the VCR automatically reserves recording of a broadcast signal of a channel at a time corresponding to the reservation information.

On the other hand, there may be a plurality of reserved recording programs as described above, and among these programs, there may be a program that a user wants to play and watch first. In the conventional VCR, in this case, the user has to control the fast forward and the fast rewind of the VCR to search the tape section in which the desired program is recorded.

However, the process of searching for the section of the tape as described above does not only require a considerable time, but also has a problem that the user must continuously perform annoying VCR operation.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to set a playback priority for each program at the time of setting the recording information, and to rank the VCR for automatically recording the recorded program according to the set order. It is to provide a reproduction method.

According to the present invention, a method of reproducing a rank of a VCR is a method of reproducing a pre-recorded program in a video cassette recorder in which information on programs for reserved recording and play order information for a playback order for each program are set. A first step of determining whether or not recording of all programs according to the information is finished; A second step of, after the completion of the first step, if the recording is ended, fast reversing to a section in which the program having the highest playback rank among the programs is recorded, and then playing the program having the highest playback rank; A third step of determining whether a program of the next reproduction rank is recorded after the reproduction terminated program after the reproduction of the program is finished; A fourth step of, if the program of the next play rank is recorded at the rear end of the finished program, playing the program of the next play rank after the fast forward to the program of the next play rank; If a program of the next reproduction rank is recorded in front of the next reproduction finished program, a fifth step of reproducing the program of the next reproduction rank after the fast reverse to the program of the next reproduction rank is provided.

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

1 shows a block diagram of a VCR for performing the rank reproducing method according to the present invention.

As shown, a deck portion 1 for reading out a signal recorded on a VCR tape is connected to the microcomputer 2. Here, the deck part 1 means all mechanisms for reading the signal of the tape in the VCR, such as a video head such as a capstan motor that is in charge of running the tape and a loading motor for rotating the head drum. Here, the video head mounted on the head drum records / reads the video signal to / from the tape, and the audio signal is recorded / read to / from the tape by a separate audio head.

The microcomputer 2 is configured to control the driving of the VCR corresponding to the driving key of the key matrix 3, that is, the driving of the deck unit 1, the image processing unit 4 described later, and the OSD unit 5, It is comprised so that this invention mentioned later may be performed.

The image processor 4 reproduces and outputs an image signal read by the deck unit 1, and the OSD unit 5 controls a predetermined OSD signal to the image signal of the image processor 4 under the control of the microcomputer 2. Are mixed to display on a monitor (not shown).

2 shows a flowchart for the microcomputer 2 to carry out the present invention.

First, in order to carry out the present invention, a user sets information on programs for scheduled recording, that is, information on a scheduled recording start time, a reserved recording end time, a channel, and the like, and in addition to the information, a playback order for each program. The information about should be set together. Further, in the VCR of the present invention, as in the conventional VCR, the vis signal must be recorded at the start of recording of one program.

As described above, the microcomputer 2 executes the flowchart of FIG. 2 in the state in which the playback order for each program is set. First, the microcomputer 2 executes all programs P1-P7 according to the reserved recording information set in step 21. If it is determined that the recording of the recording has ended, the process proceeds to step 22 if the recording has ended.

At this time, as shown in FIG. 3, whenever the recording of one program is finished, the bis signals VS1-VS7 will be recorded respectively, and the reproduction order S1-S7 to be reproduced is set in this program P1-P7. It is in a state.

In step 22, the microcomputer 2 first performs the following Equation 1 to detect the vis signal VS4 indicating the fastest playback order S1, that is, the program P4.

[Equation 1]

N- (PX-1) = A

Where N is the number of all reserved recording programs (7 in the present embodiment), and PX is the program recording order in which the playback order is the first (4 in the present embodiment because it is P4).

The A value detected by Equation 1 becomes the number of VIS signals to be detected while the VCR reverses in step 23 and becomes 4 in this embodiment. Therefore, if the VCR reverses fast until A or four Vis signals are detected in step 24, it will be readily understood that the position becomes the program P4.

The VCR which detects the tape section in which the program P4 of the reproduction rank 1 is recorded in steps 22-24 plays back the program P4 in steps 25 and 26, and when the playback of the program P4 ends, The program P1 of the next reproduction order S2 should be reproduced.

At this time, when the program of the playback rank S2 is to be played after the program of the playback rank S1 is played back, as shown in FIG. 3, the program of the playback rank S2 rather than the program P4 of the playback rank S1 as shown in FIG. P1) may be on the front side and may be behind the program P1 as shown in FIG. In the case of FIG. 3, the VCR needs to be fast reversed in order to detect and play the program P1, and in the case of FIG. 4, the VCR must be advanced in the high speed to detect and play the program P6. .

For this purpose, in the microcomputer 2 of the present invention, the order of the current program P4 is faster than the order of the program P1 (in the case of FIG. 3, P6; in the case of FIG. If it is recorded at the front end of the tape (in the case of Fig. 4), the process proceeds to step 30, otherwise it proceeds to the step 28.

In the case where the process proceeds to step 30, that is, the case of FIG. 4, the microcomputer 2 first calculates Equation 2.

[Equation 2]

A = aging sequence of the current program (PX)-(recording sequence of the next program (PX) -1)

In the case of FIG. 4, A is 4 since the current program is P4 and the next program is P1.

The microcomputer 2 having calculated this expression 2 returns to step 23, so that the program P1, which is the reproduction rank S2, is reproduced.

On the contrary, in the case where the process proceeds to step 28, i.e., in FIG. 4, the difference A of the next program P6 and the current program P4 is obtained, i. The program P6 is reproduced by driving the regeneration mode after advancing fast (step 29) until it is detected.

As described above, the present invention sets a playback order in which a plurality of programs are set in a playback order at the time of scheduled recording, and the VCR plays back the scheduled recording program according to this playback order, thereby enhancing the convenience of using the VCR. There is.
