Abstract

PURPOSE: A method for controlling a tele recording of a complex television is provided to automatically record on video tape a broadcasting of a non-seeing and hearing channel, not a seeing and hearing channel when two channels or more is reserved and recorded on video tape at the same time band. CONSTITUTION: A method for controlling a tele recording of a complex television includes five steps. A first step is to compare a tele recording reservation time to judge whether the present time is same as one among tele recording beginning times which a tele recording is reserved or not when TVCR is on. A second step is to judge whether a tele recording reservation is duplicated with a tele recording time or not when it is the tele recording beginning time in the first step. A third step is to record on video tape when the tele recording is not duplicated in the second step. A fourth step is to inquire a channel in seeing and hearing at the present time when a tele recording is duplicated at the same time band in the third step. A fifth step is to record on video tape a channel not in seeing and hearing in the fourth step.

Description

Recording Control Method for Composite Television

The present invention relates to a recording control method for a composite television. More specifically, in a two-tuner composite television having a VCR, when two or more recording reservations are made in the same time zone, a non-viewing channel is used instead of a viewing channel. A recording control method for a composite television for recording broadcasts.

A composite television receiver is a so-called TVCR (Video Cassette Recorder) that receives a broadcast signal from a broadcasting station or a signal from a television, records it on a video tape, or reproduces and outputs a signal recorded on a predetermined video tape to a screen. Is mounted on the upper or lower portion of the television.

In Fig. 1, an example of the configuration of a composite television having its VCR and Picture In Picture (PIP) functions is shown in a block diagram.

In FIG. 1, the antenna ANT is a means for receiving an over-the-air broadcast signal, and main / sub-tuners 11 and 21 are connected in parallel to the antenna ANT, and the microcomputer 50 is tuned to tune the received broadcast signal. Is controlled by The selected intermediate frequency (IFm, IFs) signals are separated into composite video signals (CVm, CVs) and audio signals by the main / sub signal processing units 12 and 22, respectively, and signal processed to process the composite video signals ( CVm, CVs) are input to the PIP image generation unit 30, and the audio signal is the speaker via the main / sub audio processing units 13 and 23 and the audio amplifiers 14 and 24 to the wireless transmitter 25, respectively. 15 is output to the headphone 26.

The PIP image generation unit 30 digitizes a video signal by an A / D converter, compresses it through a predetermined signal compression process, and then converts and mixes the D / A to output a composite video signal (CVp) for a PIP screen. The mixed video signal CVp for the PIP screen is output from the OSD unit (not shown) by the microcomputer 50 to the mixing unit 40. It is also inputted and output.

The video signal output in this way is output to the CRT to form an image. The PIP screen is generally divided into two parts, and the main screen is displayed on one side and the sub screen on the other side, or the position of the sub screen is designated. It is also displayed on the main screen.

The above-described operation is controlled by the remote controller 60, and the viewer controls the overall operation of the television remotely by pressing the output sound control, channel switching, and switching to the PIP screen. That is, the infrared receiver 51 receives the infrared signal transmitted from the remote controller 60, converts it into an electrical code, and outputs it to the microcomputer 50 so that the microcomputer 50 performs a predetermined operation according to the code table. Control.

On the other hand, the VCR 16 uses the control signals of the microcomputer 50 in the video recording / reproducing section and the audio recording / reproducing section, so that the main / sub signal processing sections 12 and 22 and the main / sub audio processing sections 13 and 23 are used. Recording and reproducing any one video signal and / or audio signal on a video tape and outputting the same to the main / sub signal processing unit 12, 22 and the main / sub audio processing unit 13, 23 to output the CRT and Outputs to the speakers 15 to the headphone 26.

However, in the conventional composite television which is configured and performed as described above, when recording for two or more channels is superimposed in the same time zone, the priority is recorded according to the reservation order or order, so that the recording is performed differently during recording. In order to watch a channel, it is inconvenient to check a recording channel, and there is a problem in that the channel having the priority is recorded while watching the channel, so that the reserved channel cannot be recorded.

Accordingly, the present invention is to solve this problem, in the case of two-tuner composite television, when two or more channels are scheduled to be overlaid in the same time zone, the broadcast of the non-viewing channel is automatically recorded instead of the channel being watched. It is an object of the present invention to provide a recording control method for a composite television.

In this case, between the recording nesting judging step and the viewing channel inquiry step: a viewing judging step of judging whether the TVCR is currently being watched when the recordings are scheduled to overlap in the recording nesting judging step; And a pre-recording step of recording the channel of the pre-recording start time until the post-recording start time when not in the viewing judging step, and recording according to the priority from the time when the recording start time is reached. In the non-viewing channel recording step, when the recording start time of the non-viewing channel is after the recording start time of the viewing channel, it is also possible to record the viewing channel until the recording start time of the non-viewing channel.

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

2 is a flowchart of a recording control method for a composite television according to an embodiment of the present invention, and FIG. 3 is a block diagram of main parts of the composite television for explaining the recording control method of FIG.

The composite television for implementing the recording control method of the present invention, as shown in FIG. 1, has a VCR and a PIP function, and includes a main / sub tuner (11, 21), a main / sub signal processor (12, 22), PIP image generation unit 30, the main / sub audio processing unit (13, 23), the audio amplifier (14, 24), the mixing unit 40 and the microcomputer 50 and the VCR (16), The functional and interconnect relationships are as described with respect to FIG. 1.

In connection with the present invention, a program for performing the following steps is stored in the internal memory of the microcomputer 50 or a separate memory means.

First, when the TVCR is turned on in step S1 in FIG. 2, a recording reservation time comparison step (step S2) is performed to determine whether the current time coincides with one of recording start times for which recording is reserved. When the recording start time is reached in the recording reservation time comparison step (step S2), it is judged whether or not the recording reservation is made to overlap with the recording time (recording overlap determination step (step S3)). In this recording overlapping judgment step (step S3), it is determined whether other recordings are reserved during the recording reservation time, in other words, whether the recording start time is within the end time of the pre-recording start time. In this case, the present invention may be performed by separately storing the overlapped reservation data and determining the recording start time thereafter.

Thereafter, when the recording is not superimposed in the recording nesting judgment step (step S3), the normal recording step is performed in step S4, and when superimposed in the same time zone, the currently viewed channel is inquired (viewing channel inquiry step (step S6)).

At this time, as a result of the inquiry in the viewing channel inquiry step (step S6), it is determined whether or not to watch, and when the channel is not being watched, the channel not being watched may be directly recorded in the non-viewing channel recording step (step S7). Control the sub-tuner 21 to the channel to be recorded by the microcomputer 50 and the signal processing unit 2 is controlled so that the composite video signal from the sub-signal processing unit 22 to the recording system 16 "of the VCR 16. In addition, the recording system 16 "is controlled by the microcomputer 50 so as to record in the recording system 16" via the recording control unit 16 '.

Meanwhile, as shown in FIG. 2, the viewing channel inquiry step (step S6) may include a viewing judgment step (step S5) and a pre-recording step (step S8).

In this case, when the recording is scheduled to overlap in the recording nesting judging step (step S3), it is judged whether the TVCR is currently being watched in the viewing judging step (step S5), and the viewer is watching at the viewing judging step (step S5). If not, the reservation recording time is judged to be partially overlapped, and then, in the pre-recording step (step S8), the channel of the pre-recording start time is recorded until the post-recording start time, and after that, the recording start time is monitored. Record according to the ranking.

In addition, in the non-viewing channel recording step (step S7), if the recording start time of the non-viewing channel is after the recording start time of the viewing channel, the viewing channel is monitored until the time is reached. You can also record.

In this manner, during the viewing, the non-viewing channel recording step (step S7) is automatically performed when the recording reservation is superimposed to record another channel that is automatically reserved without recording the viewing channel.

In addition, in the above-described embodiment, the PIP function is turned off and can be applied when the single screen unit Sm is being viewed, and the unviewed channel is a sub-tuner in the unviewed channel recording step (step S7) even when the PIP function is turned on. The content of the sub picture section Sp viewed by 21 is automatically pre-recorded. In other words, the main screen unit Mp is watching. In this case, it is preferable to be displayed on the sub-screen section Sp during recording.

In addition, although the unviewed channel is automatically recorded as described above, it may be possible to lock the unviewed channel recording function of the present invention, or to record manually after the lock even after the start of the unviewed channel.

According to the configuration and operation of the recording control method of the two-tuner composite television according to the embodiment of the present invention described above, when the recording is scheduled to overlap in the two-tuner system, a channel which is not being watched can be automatically recorded. There is such an effect.
