Abstract

A simultaneously controlling method of recording and playback in a combo device is provided to check whether broadcasting programs are normally recorded in a disk in real time by buffering the programs in a buffer memory temporarily and playing the buffered broadcasting programs. Broadcasting programs are received for MPEG decoding. Contents of a buffer are deleted when a recording signal is inputted from an input unit(S209). The decoded broadcasting programs are stored in the buffer. The stored broadcasting programs are read and recorded in a storage medium. When a play signal is inputted from the input unit, the buffer is checked and the stored contents are deleted(S215). The broadcasting programs, recorded in the storing medium, are read, stored in the buffer, and played through an output unit(S219). All the broadcasting programs are recorded in the storage medium(S213).

The present invention relates to a method for simultaneously controlling recording and reproducing in a composite product, and more particularly, to a control method capable of simultaneously recording and reproducing a broadcast program using a buffer memory.

As is well known, a composite product is referred to as a combination system, or combo-system, in which two or more different devices are connected into one integrated system. These products include a VCR / TV combo system that integrates the functionality of a video cassette recorder (VCR) and a TV, or a DVD / VCR combo that integrates a VCR deck and a Digital Versatile Disc (DVD) player. System, PVR / DVD combo system that integrates HDD and DVD, and DVD STB combo system that integrates Set-Top Box (STB) and DVD.

When recording and playing back using the composite products as described above, when a recording signal is input from a user, an MPEG program is decoded and recorded on a disc in response to the input recording signal. In addition, when a reproduction signal is input from the user, a broadcast program recorded on the disc is read in response to the input reproduction signal and reproduced by the output means for viewing by the user.

In this way, the existing composite products can not only check the contents of the broadcast program recorded on the disk, but also play back simultaneously with the recording to confirm the recorded contents while recording on the disk corresponding to the recording signal. There is a problem in that it is impossible to check in real time whether the broadcast program is correctly recorded on the disc.

Accordingly, the present invention has been made to solve the above-described problems, the purpose of which is to delete the contents stored in the buffer memory during recording, and then temporarily buffer the broadcast program using this memory and write the buffered contents to disk When the playback signal is input at the same time as the recording, the contents stored in the buffer memory are deleted, then the broadcast program to be played is read from the disc, temporarily buffered in the buffer memory, and then the buffered broadcast program is played and outputted. The present invention provides a method of simultaneously controlling recording and reproducing in a composite product that can simultaneously control recording and reproducing.

In the present invention for achieving the above object, a method for simultaneously controlling recording and reproducing in a composite product includes a first process of receiving and decoding MPEG from a broadcast program, and when a recording signal is input from an input unit, buffering is performed by first checking a buffer. A second process of deleting the recorded contents, a third process of storing the decoded broadcast program in a buffer, a fourth process of reading the stored broadcast program and recording it on a storage medium, and during playback, a reproduction signal from the input means A fifth process of checking the buffer and deleting the contents stored in the recording, a sixth process of reading the broadcast program recorded on the storage medium and reproducing it through the output means while storing the broadcast program in the buffer; Repeating step 6 is characterized in that it comprises a seventh step of recording all the broadcast program on the storage medium.

Hereinafter, a plurality of embodiments of the present invention may exist, and a preferred embodiment will be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate the objects, features and advantages of the present invention through this embodiment.

1 is a block diagram for simultaneously controlling recording and reproduction in a composite product according to the present invention, which includes an input means 101, a composite product 103, and an output means 105. As shown in FIG.

The input means 101 is a means for inputting all of the driving signals for driving the composite product 103, and recording a broadcast program on a disc (DVD or a compact disc (CD) as a storage medium) S2. And a reproduction signal for reproducing the broadcast program recorded on the disc S2 are input to the microcomputer 1037 in the composite product 103.

The composite product 103 includes a tuner section 1031, an amplifier section 1033, a memory section 1035, a microcomputer 1037, a recording section 1039, and a playback section 1041.

The tuner 1031 receives and tunes a specific broadcast program selected by the viewer among broadcast programs received through the antenna, and provides the tuner 1033 to the MPEG unit 1033.

The MPEG unit 1033 MPEG-decodes a specific broadcast program provided through the tuner unit 1031, divides the video signal into an audio signal, and outputs the divided video signal through a monitor in the output unit 105. At the same time, the memory unit (eg, the buffer) 1035 is provided, and the divided audio signal is output through the speaker in the output unit 105 and simultaneously provided to the memory unit 1035.

The memory unit 1035 deletes all the buffered specific broadcast programs during playback according to the delete command of the microcomputer 1037, and then temporarily buffers the video and audio signals corresponding to the specific broadcast programs provided from the MPEG unit 1033. (Buffering), and the buffered video signal and audio signal are supplied to the disc S2 according to the recording command of the recording unit 1039. In addition, the memory unit 1035 deletes all of the specific broadcast programs buffered at the time of recording according to the delete command of the microcomputer 1037, and then temporarily stores the video and audio signals corresponding to the specific broadcast programs provided from the disk S2. It buffers and supplies the buffered video signal and audio signal to the output means 105 in accordance with the playback command of the playback section 1041.

The microcomputer 1035 first checks and controls the memory unit 1035 according to the recording signal input from the input unit 101 to delete the contents buffered during playback to make the recordable capacity. The recording unit 1039 is controlled to record the temporarily buffered video signal and audio signal on the disc S2, and the microcomputer 1035 first gives priority to the memory unit 1035 according to the reproduction signal input from the input unit 101. The playback unit 1041 is controlled to delete the buffered contents during recording to check and control to make the reproducible capacity, and to reproduce the video signals and audio signals recorded on the disc S2.

The recording unit 1039 reads the video signal and the audio signal for the specific broadcast program buffered in the memory unit 1035 according to the recording control of the microcomputer 1037, and records them in the disc S2.

The playback unit 1041 reads the video signal and the audio signal for the specific broadcast program recorded on the disc S2 according to the playback control of the microcomputer 1037 and temporarily buffers the video signal in the memory unit 1035 so that the viewer can watch it. Output through the output means 105.

The output means 105 corresponds to all systems related to output such as monitors, TVs, speakers, LCDs, LEDs, PDPs, etc., which are output for viewers to listen to. The audio signal is output so that it can be listened to, and the video signal processed by the MPEG unit 1033 is output so that the viewer can see it. The output means 105 outputs a video signal and an audio signal for the broadcast program provided from the memory unit 1035 so that the viewer can watch.

Therefore, the system for simultaneously controlling recording and reproducing in the composite product according to the present embodiment simultaneously plays back while recording a broadcast program using a buffer memory, thereby recording on a disc corresponding to a recording signal as in the past. Not only can you record while you are there, you can't check the contents of the program you've recorded on the disc. The problem can be solved.

Next, a description will be given of a recording and reproduction simultaneous control process in the composite product in this embodiment having the above-described configuration.

2 is a flowchart sequentially illustrating a process of simultaneously controlling recording and reproducing in a composite product according to an exemplary embodiment of the present invention.

First, in the composite product, a specific broadcast program selected by the viewer among the broadcast programs received by the antenna-mounted tuner 1031 is tuned and provided to the MPEG unit 1033 (S201).

The MPEG unit 1033 performs MPEG decoding processing of a specific broadcast program tuned and provided by the tuner unit 1031, divides the video program into an audio signal, and then outputs the output video so that a user can see the separated video signal. It outputs through the internal monitor and provides it to the memory unit 1035 (S203), and outputs the divided audio signal through the speaker in the output means 105 and simultaneously provides it to the memory unit 1035 (S205).

At this time, the microcomputer 1037 in the composite product 103 determines whether a recording signal or a reproduction signal is input from the input means 101 (S207).

As a result of the determination (S207), when a recording signal is input from the input means 101, the memory unit 1035 is first checked and controlled in accordance with the input recording signal to delete the contents buffered at the time of reproduction to make a recordable capacity. (S209).

Thereafter, the microcomputer 1037 controls the recording unit 1039 to record the video signal and the audio signal provided by the MPEG unit 1033 and temporarily buffered in the memory unit 1035 on the disc S2 (S211). Then, the recording unit 1039 reads the video signal and the audio signal for the specific broadcast program buffered in the memory unit 1035 according to the recording control of the microcomputer 1037, and records them on the disc S2 (S213).

On the other hand, while recording the video signal and the audio signal for the specific broadcast program on the disc S2, as a result of the determination (S207), the microcomputer 1037 receives the reproduction which is input when the reproduction signal is input from the input means 101. The memory unit 1035 is first checked and controlled in accordance with the signal to delete the buffered contents at the time of writing to make a recordable capacity (S215).

Thereafter, the microcomputer 1035 controls the playback unit 1041 to reproduce the video signal and the audio signal recorded on the disc S2 (S217). Then, the playback unit 1041 reads the video signal and the audio signal for the specific broadcast program recorded on the disc S2 according to the playback control of the microcomputer 1037 and temporarily buffers it in the memory unit 1035 for viewers to watch. Output through the output means 105 so that (S219).

By repeatedly performing the processes from step 207 to step 219, both the video signal and the audio signal for the specific broadcast program are recorded on the disc S2 using the memory unit 1035 (S221), At the same time, the recorded contents are reproduced using the memory unit 1035. That is, referring to FIG. 3, the recording and reproducing is simultaneously performed through the disc S2 shown in FIG. 1, by controlling the reproducing unit 1041 to store an area A to be reproduced in the disc S2. Buffered to the unit 1035, and while picking up the buffered portion through the output means 105, the pick up of the tray S1 shown in Fig. 1 is alternately moved to the B area in the disc S2. The recording unit 1039 is controlled while recording. Then, the process of returning to the area A again is repeated so that recording and reproduction can be performed simultaneously.

Accordingly, by simultaneously playing back the broadcast program using the buffer memory according to the present embodiment, only the recording is possible while recording on the disc in response to the recording signal as in the prior art. Not only can not be confirmed, but also it cannot solve at the same time that the broadcast program is correctly recorded on the disc because it cannot be reproduced at the same time as recording in order to check what is being recorded.

As described above, the present invention uses the buffer memory to simultaneously record and reproduce a broadcast program, so that only recording is possible while recording on the disc corresponding to the recording signal as before. There is an effect that it is possible to solve the fact that the contents of the broadcast program could not be confirmed and that the broadcast program was not correctly recorded on the disc in real time because it could not be reproduced simultaneously with the recording to confirm the recorded contents.
