DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an information device according to the present invention. In the figure, 6 is a recording medium, 5 is a recording control unit that records received information such as image information and audio information on the recording medium 6, 7 is a reproducing unit that reproduces the received information recorded from the recording medium 6, and 21 is a control unit. Section, CPU, RO
M, RAM and the like. In FIG. 1, for convenience of explanation, the positioning unit 20 and the selector
Although only 22 is shown, it operates on various other components of FIG. In FIG. 1, this operation is indicated by a single operation line.
They are connected by a system bus composed of control lines and the like. The telephone 23 includes line connection means including a tone generator and a tone detector, a microphone, a speaker, a transmission / reception circuit, and the like.

Now, a video signal such as a television reception signal is input to a selector 22 as reception information digitized by a unit (not shown), an output is directly selected by a control unit 21, and the image information is output signal processing. The audio information is output directly to the display device 13 through the circuit 19, and the audio information is
Is output directly to At this time, if an incoming call arrives at the telephone via the line, for example, the telephone enters a talking state by going off-hook, the telephone records a telephone reception detection signal such as a signal indicating the off-hook state to the control unit 21. Give it as a start signal. The control unit 21 receives this and the selector 22
To select the recording medium 6 as the output destination of the received information. In this manner, the reception information of the continuation of the television broadcast that has been projected so far is recorded on the recording medium 6 via the recording control unit and the like as described later. Thereafter, this recording is continued until the end of recording is instructed by an operator's key operation or the like.

[0012] When the call is eventually hooked up,
The telephone 23 outputs a call disconnection detection signal such as a signal indicating an on-hook state to the control unit 21 as a recording / playback start signal. The control unit 21 receives this and issues a reproduction request to the positioning unit 20.
Upon receiving a reproduction request from the control unit 21, the positioning unit 20 positions the reproduction head at the reproduction position (recording start position) by, for example, the reproduction positioning unit included in the positioning unit 20, and performs reproduction. Also, since the positioning unit 20 is still instructed by the control unit 21 to be recording, the recording head is positioned at the recording position as before, and continues recording.

When the end of recording and reproduction is instructed by the operator and the control unit 21 receives the instruction, the control unit 21
To switch the output destination from the recording medium 6 directly to the output. At this time, the received information remaining on the recording medium without being reproduced as recorded is ignored. It should be noted that a unit for separately instructing the end of recording and the end of reproduction is provided, and when the operator instructs the end of recording, the control unit 21 receives the instruction and selects a selector.
The control unit 22 controls the recording control unit 5 to stop the recording while performing the reproduction only while the recording medium is selected, and then stops the reproduction when the operator instructs the end of the reproduction, and the selector 22 outputs the direct output. select.

When a telephone call or a recording start signal described later is received again during recording / reproduction, only recording is performed. Also,
During a call, image information received from the other party can be output to the display device 13. This is realized by outputting the image information sent via the line to the display device 13 via the control unit 21, the selector 22, and the output signal processing circuit 19. At this time, for example, the control unit 21 performs a conversion for making the same data format as the television reception information, or the transmission side makes this data format and transfers.
In the above description, the telephone 23 can be an ISDN interface for transmitting and receiving voice and images.

An instruction to enter the recording mode can be given by a visitor detection signal. For example, a television camera and a doorbell are provided at the entrance, and a signal for ringing the doorbell is input to the control unit 21 as a recording start signal instead of the off-hook signal. Further, it is also possible to process image information input from the television camera like image information input via the line and display the processed image information on the display device 13.

Further, it is also possible to receive a recording start signal for entering the recording mode as a signal generated by operating an operation key of a remote controller, for example, and give the signal to the control unit 21.
Similarly, the recording / playback start signal to enter the recording / playback parallel mode can be given by operating the operation keys of the remote controller. The signal generator of the remote controller and the receiving circuit on the information device side such as the television receiver are well known to those skilled in the art, and thus the description thereof is omitted.

Next, a method for simultaneously executing recording and playback with one head will be described. FIG. 2 is a block diagram showing an embodiment of a main part of the information equipment according to the present invention. In the figure,
1 and 2 are reception buffer memories for storing digitized reception information, 3 is a compression unit for compressing the data amount, 4 is a compression information buffer for temporarily storing information compressed by the compression unit 3, and 5a is a compression information buffer. Information is stored in a disk-type recording medium 6
This is a recording control unit for recording on a. In the above,
The disk-type recording medium 6a is a recording medium having concentric or spiral recording tracks, such as a hard disk or a magneto-optical disk. 7a is a recording medium 6a
A reproducing unit for reproducing the information recorded from the recording order
Is a compressed information buffer for temporarily storing the reproduced compressed information, 9 is a decompression section for decompressing the compressed information to the original information, 10 and 11 are reproduction buffer memories for storing decompressed image information, and 12 is a reproduction buffer. It is a frame memory that reads out the frames from 10 or 11 in the order of reproduction in the unit of a frame and holds one frame of output image information in the layout of the output screen.

Normally, recording is performed exclusively by the recording / reproducing unit configured as described above. At this time, the digitized reception information is first stored in the reception buffer memory 1 in a continuous area in the order of reception, and after storing a predetermined number of frames (for a predetermined time), the reception information is stored in the reception buffer memory 2 in the same manner. Is done. On the other hand, when the storage in the reception buffer memory 1 is completed, the control unit (not shown) reads the reception information from the reception buffer memory 1 in the order of reception and inputs the information to the compression unit 3 comprising a dedicated compression circuit. Compressed image information compressed to a degree is obtained. The compression information output from the compression unit 3 is temporarily stored in a compression information buffer 4 and then, together with the audio information given as a pair with the image information by a unit (not shown), is recorded on the recording medium 6a by the recording control unit 5a. Be recorded. This recording is performed on the areas that are continuous in the order of reception. In the above description, the output speed from the reception buffer memory is set to be several times faster than the speed of storing in the reception buffer memory, and the recording speed by the recording control unit 5a is the output speed from the reception buffer memory because the information is compressed. This is performed at a throughput that follows the output throughput of the compression unit 3 which is about 1/30 of the above.

The reading from the reception buffer memory 1 is completed before the reception to the reception buffer memory 2 is completed, and when the storage in the reception buffer memory 2 reaches a predetermined number of frames, the reception information is stored in the reception buffer memory 2. 1 and a process of reading data from the reception buffer memory 2 and recording the data in a continuous area of the recording medium 6a is performed. Hereinafter, this repetition is performed.

If the reproduction is started before the recording is completed, the following operation is performed. First, the head of the recording medium 6a is controlled by the positioning unit 20 and moved to the reading position. This position is the head position of the area recorded at that time. Subsequently, a predetermined amount of reproduction is performed by the reproduction unit 7a. The compressed information read out in the recording order is stored in the compressed information buffer memory 8.
, And is expanded to a state before compression by the expansion unit 9 and stored in the reproduction buffer memory 10. During this time, the subsequent reception information is continuously input, and is stored in the reception buffer memory 1 or 2 as described above.

When the predetermined amount of data is stored in the reproduction buffer memory 10, reading from the reproduction buffer memory 10 is started, and the image is displayed on the display device 13 via the frame memory 12 at a speed of, for example, 30 frames / sec. It is. Also, the recording medium 6
The head on "a" is moved to the recording position again, the subsequent received information is read from the reception buffer memory 1 or 2 as described above, and the compressed information is recorded on the recording medium 6a as described above. When the recording of the predetermined amount of received information is completed, the head on the recording medium 6a is moved to the reproduction position again, and the expanded image information is output from the expansion unit 9 as described above. It is stored in the reproduction buffer memory 12.

In the above description, the time required to output a predetermined amount of information from the reproduction buffer memory is the time required to record the same amount of received information on the recording medium as the time required to reciprocate between the recording and reproduction positions, and the time required to reproduce the information from the recording medium. Is set to be longer than the sum of the times to store the same amount of decompression information in the playback buffer memory, so that the output of the image information that is subsequently output before the output from one of the playback buffer memories is completed. The storage in the other reproduction buffer memory ends. In the same manner, recording (recording) and reproduction are alternately repeated in the same manner. During this time, the operation of storing the received information in the reception buffer memory and the operation of reading it out from the reproduction buffer memory and projecting it are continuously continued.

In the above, the compression / decompression unit is provided for the purpose of reducing the amount of information to be recorded and for the purpose of shortening the recording / reproducing time. It is not always necessary if the sum of the recording / reproducing time and the round-trip time between the recording / reproducing positions can be shorter than the receiving time or the output time by making the output speed higher than the output speed to the display device.

The received information is composed of image information and audio information. Digitized audio information corresponding to an image of a predetermined frame is stored in a specific area in the reception buffer memory 1 or 2, for example. When a fixed amount (predetermined frame) of an image is recorded on a recording medium, the image is recorded in an area continuous with the image information. When the recorded audio information is reproduced by the reproducing unit 7, it is first stored in the reproduction audio buffer memory 14, and when the corresponding image information is output from the reproduction buffer memory, the reproduction audio buffer memory 14 is synchronized therewith. From the decoder 15, the DA converter 16
Are amplified and amplified by the amplifier 17 and output to the speaker 18. In view of the relationship of the required time, it is desirable that the moving time of the head be negligible compared to the recording / reproducing time. There is a need to.

FIG. 3 schematically shows a flow at the time of the above-mentioned parallel recording / reproduction operation. The numbers in circles in FIG. 3 are numbers indicating the order of processing. The block shown in FIG. 3 is a unit of recording / reproduction per recording, that is, a predetermined amount of received information. The target block of the first recording is block 1 and the target block of the n-th recording is block n. It is. That is, the flow of FIG. 3 starts from recording block n. Immediately before this, recording from block 1 to block n-1 was performed without performing reproduction.

As a recording medium, two video tapes which can be independently recorded and reproduced are provided, and the already recorded portion is reproduced and projected as described above while recording a television signal or the like being received. It is possible. In this method, after recording an arbitrary amount of reception information on the video tape, a reproduction operation for reproducing from one video tape in accordance with a recording order and a recording operation for recording the subsequent reception information on the other video tape are performed in parallel. When the reproduction of the received information by the video tape being reproduced is completed, the operation of recording the subsequent received information on the video tape and reproducing the information from the video tape being recorded is repeated.

FIG. 4 is a block diagram showing a main part of this embodiment. When the control unit 25 receives a recording start signal from a unit (not shown), for example, it first controls the selector 26 and passes the received information to the first tape recording control unit 28. At the same time, the control unit 25
Give an instruction by the tape drive unit 28, drive the tape,
The first video tape 31 is recorded. Eventually, when the control unit 25 receives the recording / playback signal, the control unit 25 controls the selector 26 so that the reception information being continuously received is transferred to the second tape recording control unit 30, and at the same time, the second tape drive unit 29 Is driven to record on the second video tape 32. The control unit 25 further instructs the first tape drive unit 27 to cause the first video tape 31
To the recording start position, and the first tape playback unit 33
The received information recorded on the first video tape 31 is reproduced.

The first tape driving section 27 stores the recording end position, and when reaching the position, notifies the control section 25 to that effect. In response to this, the control unit 25 terminates the reproduction of the first tape, controls the selector 26, and transfers the received information to the first tape recording control unit 28. During this time, the first tape drive unit 27 continues to drive the first tape 31. At the same time, the control unit 25
An instruction is issued to the tape drive unit 29 to return the second tape 32 to the recording start position.
The received information recorded in is reproduced. This is repeated below.

In the above case, viewing during the rewind period is interrupted. As described above, this problem can be solved by digitizing the television signal and providing a reception buffer memory or a reproduction buffer memory. For example, when the drive unit during reproduction gives an instruction to the control unit 25 shortly before the reproduction end position, the control unit 25 immediately stops recording on the other tape and starts rewinding. However, it is still too early to pass the received information to the tape being played back at that time, so the received information during that time is stored in the receiving buffer memory, and the first predetermined period when the reproducing side switches to the recording side is the above-mentioned receiving buffer. When the recording speed is made faster than the storage speed in the memory and the reception information in the reception buffer memory becomes empty, the reception speed and the recording speed are made the same. In the above,
The first tape drive unit 27 and the second tape drive unit 29 are positioning units
20a. In the above description, it goes without saying that the reception information to be recorded / reproduced is not limited to the television signal, but is applicable to all video signals transmitted wirelessly or by wire.

By the way, in the recording / reproducing according to the prior art, when a certain program is being watched and a program of another channel being simultaneously broadcast is recorded and reproduced, the program is recorded even when the program being watched ends. If the program is not reproduced after the program ends, the entire program cannot be recorded. On the other hand, if a part of the present invention is implemented, when the program being watched ends, even if the program being recorded does not end, the recording and playback are performed simultaneously, thereby immediately reproducing the program being recorded. You can start and play to the end of the program. A part of the present invention is configured to include a unit that, when a recording / playback start signal is detected during recording, performs reproduction of the recording information during recording and subsequent recording of the video being recorded in parallel. That is. It is apparent from the above description that the above-described function can be achieved by the configuration without needing to be described again.

[0031]

As described above, according to the present invention,
By giving the recording start signal, the recording being displayed is automatically started, and by giving the recording / playback start signal during the recording, the reproduction of the recording information being recorded and the subsequent recording of the video signal being recorded are continued. Because it can be done in parallel, even if various factors such as telephones and visitors that interrupt viewing of TV etc. occur,
Immediately after the termination of the interruption factor, the program being viewed can be viewed without any loss. If the interruption is due to a phone call,
During a call, the face of the other party can be displayed on a display device such as a television, and in the case of a visitor, the face of the visitor can be confirmed on a display device such as a television without opening a door, so that the display device can be effectively used.

By providing a recording / playback start signal, the reproduction of the recording information during the recording and the subsequent recording of the video signal being recorded can be performed in parallel. Even if the program in progress has not ended, the program being recorded can be immediately reproduced and the program can be viewed to the end. Further, since the recording and the reproduction can be performed in parallel by one head, the above effects can be realized at low cost.

Further, by using a video tape to automatically start recording during projection and providing a recording / playback start signal during the recording, reproduction of recording information during recording and reproduction of the video signal during recording are performed. Since the operation of performing the subsequent recording in parallel can be realized, the applicable range of the present invention is expanded. Furthermore, since the information to be recorded on the recording medium is configured as the compressed information, the recording time that can be recorded on the recording medium can be extended, so that it is possible to cope with a long interruption or a frequent interruption.
