Description

Daily scheduled recording of the video cassette recorder

The present invention relates to a video cassette recorder (hereinafter referred to as a VCR), and more particularly, to a method for automatically searching for a section to be recorded when daily recording is performed using one video tape.

A VCR is a device that selectively magnetizes a magnetic video tape as a head to record video and audio signals or to read video and audio signals recorded on a video tape.

In particular, such a VCR has a built-in microcomputer for controlling the driving of the VCR therein, and thus a reservation recording method using the microcomputer function is widely used. That is, when a user inputs reservation information about a recording date, a recording start time and a recording end time, and a recording channel, the VCR automatically schedules recording of a broadcast signal of the channel at a time corresponding to the reservation information.

One of the scheduled recording methods of such a VCR is a daily scheduled recording function. The daily schedule recording function records broadcast signals of the same channel every day at a preset recording time set by the user, and is useful for dramas or educational broadcasts that are broadcasted daily.

On the other hand, during the daily scheduled recording, it is preferable that the broadcast signal of the reserved channel is sequentially recorded on one video tape in sequence. Therefore, conventionally, the user has no choice but to search for a section in which a video recording is to be performed while one video tape is loaded.

However, in order for the user to search the recording section as described above, the video tape is searched by fast rewind or fast forward, which wastes time, and in particular, power consumption for the operation of the VCR occurs. there was.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to provide a daily scheduled recording method of a VCR that enables to automatically search for a section to be newly recorded when performing daily scheduled recording.

The present invention includes a first step of storing a recording time of a reserved program to be performed when a daily scheduled recording mode is set in a first buffer; A second step of recording according to the set reserved recording information when the scheduled recording start time according to the daily scheduled recording is reached after the execution of the first step; A third step of adding and storing the time of the first buffer to the second and third buffers after performing the second step; A fourth step of running the tape and calculating the running time of the tape if a command requiring the running of the tape is applied after the execution of the first step before the scheduled recording start time; A fifth step of restoring the time of the third buffer by adding / subtracting the time stored in the third buffer to the tape running time after performing the third or fourth step; And a sixth step of subtracting the time of the second buffer from the time of the third buffer and running the tape corresponding to the subtracted time.

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

Fig. 1 is a schematic block diagram of a VCR for performing a VCR recording method according to the present invention, as shown in the tuner 1, the recording processing system 2 and the reproduction processing system 3, the deck 4, the microcomputer. (5) and key metrics (8), and an OSD section (7).

Here, the tuner 1 receives a broadcast signal of a predetermined channel under the control of the microcomputer 4, and the recording processing system 2 receives an image of the channel received by the tuner 1 under the control of the microcomputer 5. It is configured to record and apply an audio signal to the deck 4.

The deck 4 is configured to record the video signal of the recording processing system 2 on the video tape under the control of the microcomputer 5, or to read the signal of the video tape and apply it to the reproduction processing system 3.

On the other hand, the reproduction processing system 3 reproduces and outputs the video and audio signals detected by the deck 4, and the OSD unit 7 outputs a predetermined OSD signal under the control of the microcomputer 5 to reproduce the processing system 3 The signal is mixed with the signal and applied to the monitor.

In addition, the microcomputer 5 is configured to control the above-described components in response to the key selected, i.e., pressed by the user among the various function keys of the key matrix 8.

In addition, the microcomputer 5 of the present invention includes three buffers, namely, a recording time buffer B1, a tape travel time buffer B2, and a current tape position time buffer B3, for carrying out the present invention as described below. Should be configured.

2 is a flowchart of a program for storing reservation recording information of a foreign currency program in the microcomputer 5 for carrying out the present invention.

First, the microcomputer 5 of the present invention determines whether the current daily reserved recording mode is set in step 21, and proceeds to step 22 if the daily reserved recording mode is set.

In step 22, the microcomputer 5 stores the recording time of the reserved program to be performed, that is, the time obtained by subtracting the reserved recording start time from the reserved recording end time (step 23).

Then, the microcomputer 5 continuously determines whether the current time is the reserved start time (step 24) and proceeds to step 25 if the start time is the reservation start time. In step 25, the microcomputer 5 controls the tuner 1, the recording processing system 2, and the deck 4 together to record the broadcast signal of the set reserved channel until the reserved recording end time (steps 26 and 27). .

Then, the microcomputer 5 adds and stores the time of the buffer B1 to the above-described buffers B2 and B3 (step 28).

On the other hand, if the microcomputer 5 receives a key signal requiring travel of the playback mode and the high-speed driving tape from the key matrix 8 from the key matrix 8 before the reservation recording start time (step 29), the determination result of step 24 (step 29) And proceeds until the stop key signal of the key matrix 8 is applied (steps 31 and 32).

Then, the microcomputer 5 converts the running time of the tape to the running time of the tape at the time of reproducing (that is, when the tape runs at a higher speed than at the time of reproducing and recording at high speed, the driving time is converted into the recording time). The tape run time is calculated (step 33). After performing step 33, the microcomputer 5 resets the time of the buffer B3 by adding / subtracting the time stored in the buffer B3 to this tape running time (step 34), and from the time of the buffer B3. The time of the buffer B2 is subtracted (step 35).

That is, the buffer B2 stores information on the tape travel time when recording is completed, and the buffer B3 stores time information on the current position of the tape. If the tape is moved in response to the time difference (step 36), the tape will be located at the point corresponding to the buffer B2, that is, the point where the recording is completed.

That is, according to the present invention, the tape travel time at the time when recording is completed is stored in the buffer B2, and the tape travel time is stored in the buffer B3 as the tape moves. When the movement of the tape is completed, the tape can be positioned at the point where the recording is completed by removing the tape according to the time difference between the buffers B2 and B3.

Therefore, the present invention has the effect that the tape is always located at the time point at which the recording is completed at the time of performing the scheduled recording every day, so that the program can be continuously recorded.
