DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver incorporating a recording means (for example, a video tape recorder: hereinafter referred to as a VTR) capable of recording a video signal and a VTR alone.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional VT using voice discrimination.
It is a figure which shows the block of a television receiver with a built-in R. Reference numeral 1 denotes a speaker that amplifies and outputs an input audio signal, and 2 denotes a CRT (also called a cathode ray tube) that displays the input video signal. Reference numeral 3 denotes a VTR for recording the input audio signal and video signal.

[0003] Reference numeral 4 denotes an audio multiplexing mode discriminating circuit for discriminating an audio multiplexing mode of an input audio signal. Normally, the audio multiplex mode is determined by stereo broadcast and double audio broadcast,
Difference in pilot signal frequency depending on monaural broadcasting (stereo: 982.5 Hz, dual sound: 92
2.5 Hz) and the presence / absence of a pilot signal (monaural has no pilot signal). In addition, there is a type in which a sub-channel audio signal is used in the above-described determination so as not to malfunction due to noise or the like.

Reference numeral 5 denotes a decoding processing circuit comprising a CPU, which includes a key unit 9, a remote control unit 10, and an external changeover switch 11.
Is decoded, and the selected or current audio multiplex mode of the received broadcast is output to the plurality of LEDs 12 so that the viewer can recognize the mode. Further, the LED 12 may be other means as long as it displays the sound mode, and may be, for example, a fluorescent display tube.

[0005] Reference numeral 6 denotes a case where the audio multiplex mode of the input audio signal is compared with the audio multiplex mode selected by the viewer using any one of the key section 9, the remote control section 10, and the external changeover switch 11, and when they match. Only the VTR 3 performs the recording operation,
An audio multiplex mode comparison circuit that stops the recording operation if they do not match.

Reference numeral 7 denotes a display control circuit for setting a display position of a display screen in a recording setting mode from the decoding processing circuit 5, and the like.
Reference numeral 8 denotes a display matrix circuit that switches a signal from the display control circuit to a video signal and outputs the signal to the CRT 2.

Next, the operation will be described with reference to FIG.

First, there are the following methods for recognizing the currently received voice multiplex mode. As a first method,
The received audio signal is input to the audio multiplexing mode discriminating circuit 4, and its output is decoded. For example, the audio multiplexing mode itself such as "stereo", "double sound", or "monaural" is displayed on the upper right of the CRT by using an on-screen IC. As a second method, when a channel is displayed on the upper right of the CRT by an on-screen IC, the display color of the channel is yellow for stereo, red for dual sound, and monaural. There is a method of setting a color such as green in advance and displaying the color.

As a third method, the output from the audio multiplex mode discriminating circuit 4 is decoded, and for example, a plurality of LEDs 12 arranged in a cabinet holding a CRT are used. By turning on different LEDs or changing the emission color of the LEDs in accordance with the reception state of the audio multiplex mode, the viewer could recognize the audio multiplex broadcast of the broadcast being received by the viewer. .

Next, a method for recording a specific audio multiplex broadcast will be described.

When a viewer operates a recording reservation button on either the key section 9 or the remote control section 10 by a viewer, a recording reservation screen (FIG. 6) is displayed.
"10CH 28th (Fri) 9:00 pm to 10:52 pm
If "double sound triple" is set, the specified channel is set to be recorded at triple speed at this date and time.

At the time of recording, the audio multiplex mode comparison circuit 6 operates so as not to record a broadcast other than the audio due to the designation of the dual audio. That is, when a stereo broadcast or a monaural commercial (hereinafter referred to as a CM) is broadcast between the double audio broadcasts, the broadcast is determined by the comparison circuit 6 and the recording of the VTR is stopped. In addition, when the designated program is delayed due to some influence, the designated program can be recorded by shifting only the recording start time and the recording end time or the recording start time by the delay time when the dual audio broadcasting starts. .

As a second method, there is a method of setting an audio multiplexing mode of a program designated by the external changeover switch 11 and making a recording reservation. In this case, the recording reservation is not made in the audio multiplex mode, and the audio multiplex mode is set by the external switch 11.

At the time of recording, the external switch 11
The video signal of the audio multiplex mode specified by is recorded.

Therefore, according to the above two methods,
The video signal recorded by the VTR is only a program broadcast in double audio, and the user can smoothly watch the program without reproducing unnecessary broadcasts other than the program when the program is reproduced. Further, the recording medium (here, a video tape) used for recording is minimized, and the cost of the recording medium is reduced.

However, the audio multiplex mode is determined,
In order to record, an audio multiplex mode discriminating and displaying means is specially required.

[0017] Even if the program is currently being viewed,
The audio multiplex mode had to be set, and the operability was poor.

[0018]

[0022]

According to the present invention, the audio multiplex mode of the program to be currently viewed and recorded is held, and the held program in the audio multiplex mode alone is recorded.

[0023]

FIG. 1 is a circuit block diagram of an embodiment of the present invention. The same portions as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

The audio multiplexing comparison circuit 13 stores the output from the audio multiplexing mode discriminating circuit 4 and the audio multiplexing mode when the recording operation is performed by the key 9 and the remote controller 10 from the audio multiplexing mode discriminating circuit 4. The output from the circuit 14 is compared.

Next, the operation will be specifically described with reference to the flowchart shown in FIG. First, voice setting recording is performed in step 10
Start with 1. In step 102, it is determined whether the key 9 for storing the currently received audio multiplex mode or the audio selection recording key provided on the remote controller 10 has been operated. And wait until the operation is done,
When an operation is performed, the audio multiplex mode received at the time of the operation is held by the audio mode holding circuit 14 in step 103.

Thus, the setting of the recording condition is completed, and the process proceeds to the recording execution. Then, the audio mode currently being received is extracted by the audio multiplex mode determination circuit 4 and compared with the held audio mode held by the audio mode holding circuit 14 (step 10).
4). If they match, in step 105, the recording operation is executed (or continued if it is being executed). However, if they do not match, the video / audio signal is not desired to be recorded, and the recording operation is stopped or temporarily stopped (step 106).

Then, the audio setting recording is terminated under the condition that the recording cannot be performed (for example, the recording medium (video tape or the like) is extracted from the main body, the capacity of the recording medium is exceeded, or the operation of the key indicating the release) (steps 107 and 108). I do. Unless an operation indicating the cancellation is performed, the process returns to step 104 and this flowchart is repeated.

A supplementary explanation will be given using a specific example. For example, an audio selection recording key is operated while receiving a double audio video / audio signal. Thereby, the audio mode holding circuit 14
And the recording is started. When the mode is changed to the stereo mode at the time of recording, the signals input to the audio multiplex mode comparison circuit 13 are different from each other, so that the recording of the VTR 3 is temporarily stopped. However, when the stereo is released and the sound becomes double sound, the pause state is released again by the sound multiplex mode comparison circuit 13 and the recording is resumed.

Therefore, it is possible to record a broadcast only in the audio multiplex mode at the time when the audio selection recording key is operated, and it is possible to record only a desired audio multiplex broadcast by a simple operation.

FIG. 3 is a circuit block diagram of a second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The difference from the first embodiment is that a display control circuit 15 is provided. This display control circuit 15
Receives a signal indicating that the voice selection recording is being performed, and can display a notice to that effect (for example, "double voice recording") so that the viewer can be clearly notified when the voice selection recording key is operated. Even if the timing of pressing the voice selection recording key is shifted and undesired voice selection recording is performed, the correction can be performed immediately. That is, for example, “stereo recording” is displayed, and it is understood that the recording is not the desired double audio recording.

Next, a third embodiment of the present invention will be described with reference to the flowchart shown in FIG. First, audio setting recording starts in step 201. In step 202, it is determined whether the key 9 for storing the currently received audio multiplex mode or the audio selection recording key provided on the remote controller 10 has been operated. Then, the operation waits until an operation is performed. When the operation is performed, the audio multiplex mode received at the time of the operation is held by the audio mode holding circuit 14 in step 203.

In step 204, the voice selection recording key 2
The number of presses above the number of times is counted, and the recording time is set, for example, every 15 minutes per count number 1. In other words, a recording time of 15 minutes can be set by pressing twice, 30 minutes by 3 times, and 1 hour by 5 times. Further, a recording time setting key may be separately provided, and in this step 204, the recording time is set.

Then, the setting of the recording conditions is completed, and the process proceeds to the recording execution. The audio mode currently being received is extracted by the audio multiplex mode discrimination circuit 4 and compared with the held audio mode held by the audio mode holding circuit 14 (step 205). If they match, in step 206, the recording operation is executed (or continued if it is being executed). However, if they do not match, the video / audio signal is not desired to be recorded, and the recording operation is stopped or temporarily stopped (step 207).

Then, a condition under which recording cannot be performed (for example, a recording medium (video tape or the like) is removed from the main body, the capacity of the recording medium is exceeded, or an operation of a key indicating release) is performed, or an audio setting recording is performed according to the lapse of the time set earlier. Is completed (steps 208 and 209). Unless an operation indicating the cancellation is performed or the recording time has not elapsed, the process returns to step 205 and repeats this flowchart.

Therefore, an arbitrary audio multiplex mode can be recorded by a simple operation and the recording time can be set, so that waste of a recording medium (a video tape or the like) can be reduced.

The fourth embodiment will be described with reference to the circuit block diagram of FIG. At the time of normal recording setting, "10CH 29th (Fri) 9: 00 pm as shown on CRT2 in FIG. 6:
00 to 10:52 double sound tripled "is stored in the decode processing circuit 5. Recording is performed only when the output of the decode processing circuit 5 matches the output of the audio multiplex mode determination.

Next, when the audio selection recording key is selected,
The audio multiplex mode received at that time is held in the audio mode holding circuit 14. When the audio multiplex mode comparison circuit 13 determines that the audio multiplex mode is held by the audio mode holding circuit 14, the audio multiplex mode input from the decoding processing circuit 5 is invalidated, and the audio mode holding circuit 14 The voice multiplexing mode is input as a reference for comparison. That is, the audio multiplex comparison circuit 1
3 operates the audio selection recording key, compares the selected audio multiplexing mode with the currently received audio multiplexing mode, and controls the recording of the VTR 3 based on the selected audio multiplexing mode.

Therefore, it is possible to perform recording by the conventional recording setting, and when the operation means for instantaneous recording such as the audio selection recording key is operated, it is possible to perform recording in the set audio multiplex mode. It becomes possible.

[0039]

According to the present invention, by operating an operation unit such as an audio selection recording key while viewing an arbitrary broadcast to be recorded in the audio multiplex mode, the audio multiplex mode of the broadcast being viewed can be stored. Then, after the storage, the stored audio multiplex mode is compared with the current mode at any time, and the broadcast to be recorded can be recorded.
