Also, when the second bit is 0 and the third bit is 0, the television audio signal is stereo, and when the second bit is 0 and the third bit is 1, the television audio signal is It represents that it is a monaural 2 channel signal (recorded in audio 1 and audio 2 in the format of FIG. 4). When the second bit is 1 and the third bit is 0, it means that the television audio signal is a monaural 1-channel signal (recorded in audio 1). The state where both the second bit and the third bit are 1 is not particularly used.

When the fourth bit is 0 and the fifth bit is 0, it means that the additional voice is stereo, and when the fourth bit is 0 and the fifth bit is 1, the additional voice is added. It indicates that the sound is a monaural 2-channel signal (recorded in the sounds 3 and 4). Further, when the fourth bit is 1 and the fifth bit is 0, it indicates that the additional voice is a monaural 1-channel signal (recorded in the voice 3). When both the 4th bit and the 5th bit are 1, it indicates that a signal other than voice is transmitted.

Further, the 16th bit is set to 1 when the voice output is suppressed and is set to 0 when the suppression is released.

[0030]

[Table 2]

As shown in FIG. 4, in the first 2 × 32 bit range, the next 10 × 32 bit range, and the subsequent 10 × 32 range, voice data of voice 1 to voice 4 are respectively provided. Is recorded. 1
32 samples of audio data are arranged in each range of 0 × 32 bits. That is, the number of bits per sample is 1.
It is set to 0 bit. However, the analog audio signal is converted into 14-bit digital data per sample. Of these, the upper 10 bits of the significant digit are selected and transmitted as one sample of data. That is,
As shown in FIG. 5, the upper 10-bit data of the significant digit of the 14-bit data is selected, and therefore there are five ranges to be selected. The range bits recorded in the first range of 2 × 32 bits indicate which of the five ranges is 10 bits.

In the A mode, the audio data of one channel is arranged in this 10 × 32 bit range, but in the B mode, 20 × 3.

It is possible to display the TV program section as shown in FIG.

The LCD 85 is integrated with the touch panel 8
When No. 1 is attached and a predetermined position on the touch panel 81 is touched with a finger or the like, the coordinate data is supplied to the input processing device 82. In the case of this embodiment, the LCD 85
A scroll key for moving the cursor shown in FIG. 16 vertically and horizontally is displayed. By operating this scroll key via the touch panel 81, the cursor can be moved to a predetermined position.

When the user operates a predetermined position in the cursor on the touch panel 81, the CPU 86 generates the coordinate data on the program section from the coordinate data input by the input processing device 82 at that time.

That is, as shown in FIG. 15, the range displayed on the LCD 85 is a part of the program section. The coordinate data output by the input processing device 82 is the point P (x, x, xy coordinates in FIG. 15 on the touch panel 81.
It is the coordinate data of y). Now the origin Q of this xy coordinate
If the coordinates on the program section (XY coordinates) of are (X, Y),
The coordinates of the point P on the XY coordinates of the program section are (X + x,
Y + y). The CPU 86 divides X + x by the width W of the channel shown in FIG. 15, rounds down the decimal part of the quotient, and adds 1 to the integer part to obtain channel data (for any channel from channel 1 to channel N). Data) indicating whether there is.

Further, the CPU 86 stores the data of the program displayed at the coordinate position Y + y of that channel in the RAM 8
Read from 7. Then, the data corresponding to the read program information is output to the remote control signal generation circuit 89. As a result, the remote control signal generation circuit 89 causes the LED 90 to generate an infrared signal corresponding to the program information selected by operating the touch panel 81. LED9
The infrared signal generated from 0 is transmitted to a remote control receiving circuit of a video tape recorder (not shown). This allows the video tape recorder to reserve recording.

The program column data recorded on the mini disk 72 can be not only a program column for one day but also a program column for one week or January.

In the embodiment of FIG. 18, the touch panel 81 is used for inputting.
It is also possible to input with an input pen, a keyboard, or the like.

Furthermore, the program information data is
It can be transmitted several times at a predetermined time.
