2. Description of the Related Art On the other hand, there is a conventional means of reservation recording. If a time and a channel are designated in a video apparatus, a broadcast program can be recorded automatically. In the means, the transmitting side modulates information such as music and conversation on a carrier wave and transmits it. The receiving side receives the information by an antenna and a receiver, extracts information from the modulated wave, and outputs the information to a magnetic tape of a video device. In this method, the data is stored in a storage medium such as a lamp, amplified when necessary, and reproduced on a cathode ray tube, a speaker, or the like.

(A) In order to make a scheduled recording, a program to be watched by the user must be selected in advance from a program column of a newspaper or a weekly schedule, and must be written for each program in accordance with the operation procedure of the recorder. It is very troublesome for a busy person to perform this frequently, and therefore, the utilization rate of the scheduled recording by the video apparatus is low unless it is particularly necessary. (B) In normal recording, recording is performed on a magnetic tape in the order in which it was broadcast. Therefore, when the program is taken out, it can only be taken out in the recording order. It is troublesome to search for a recording place while sending by fast forward etc. because it cannot be picked up.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below . Numerical values for television broadcasting, radio AM broadcasting, FM broadcasting, short-wave broadcasting, etc.
For analog broadcast programs that do not include digitalization. In transmission of these broadcasts, first, a wave of a fixed width called a carrier wave is modulated on information such as music and conversation, and this is incorporated in a transmission circuit and amplified for broadcasting. However, in the transmission according to the present invention, information relating to broadcasting is classified, a code number corresponding to the classification type is set, the code number is converted into a binary data signal, and an occupied frequency band of a transmission wave of television and radio broadcasting is transmitted. In this method, the binary data signal is modulated and broadcast in a corner area that does not affect normal broadcasting, in a gap between pilot signals of FM broadcasting, or between a sub-channel and an SCA channel. The binary data signal is
The binary signal code of “0” or “1” is inserted and transmitted from the transmitter. The specific method of transmitting the binary signal of “0” or “1” is based on the occupation of the broadcast wave. Shift signals f 1 and f 2 having constant amplitudes are transmitted at two different frequencies within the frequency bandwidth, and f 1 is defined as “0” and f 2 is defined as “1”. At this time, the amplitudes of f 1 and f 2 are at least large enough to be distinguished by a receiving system described later, but f 1 and f 2 may be confused with the frequency components of the information contained in the sidebands. Yes, the following measures are taken to solve it. That is,
The amplitudes of the frequencies f 1 and f 2 are set to the amplitudes and transmission times equal to or greater than the frequency components indicated by the normal information, and the frequencies f 1 and f 2 are used by the frequency components of the normal information in the occupied frequency bandwidth. FIG. 1 shows a spectrum set at a corner area where the frequency is not set and the spectrum of the frequency is displayed. It is desirable that the shift frequencies of f 1 and f 2 are separated from each other, but there is no problem if an interval of 100 Hz or more is maintained. Although the shift signal becomes noise as it is, a trap circuit may be incorporated in a demodulator on the receiving side to be described later and removed. As a specific example of the shift signal, for example, in the first broadcast of NHK, the carrier is 594 kHz and the occupied frequency bandwidth is about 15 k.
Hz, 601 kHz is set to "0" and 600.9 kHz is set to "1" from the surrounding sideband.

Alternatively, the occupied frequency band of a normal AM broadcast has information on the left and right sides of a carrier, but in the present invention, only one of the left and right is used for information, and the shift signals f 1 and f 2 are used for the other.
, A data signal can be sent together with the information.

In setting the binary data signal, FM
In the case of broadcasting, as shown in FIG. 2, since there is a non-audible range between the upper and lower gaps of the pilot signal for stereo broadcasting or the sub-channel and the SCA channel, the shift signals f 1 and f are located in the non-audible range. Insert 2 . Then, on the one hand, the monaural broadcast is played, and on the other hand, the shift signals f 1 , f 2

The start signal causes a receiver described later to start preparation for binary data signal decoding, and the stop signal
Conversely, the end of the transmission of the binary data signal is notified to the receiver. Among them, the stop signal is usually inserted for the purpose of confirmation, although the end can be sensed without this.
As the start signal and the stop signal, for example, as shown in FIG. 3, before and after the data signal, a shift signal corresponding to the above “0” is sent for a predetermined time.

Next, a method and an apparatus for receiving, editing and reproducing a radio wave including the binary data signal will be described with reference to FIGS. First, the same radio wave is received by a receiver through an antenna, a carrier is separated from a modulated wave, and information is extracted and demodulated. This is the same as in the related art. However, in the present invention, a plurality of channels are used for this reception. Since simultaneous reception is required, a receiver capable of simultaneously receiving a plurality of channels is used, or a plurality of receivers corresponding to the number of channels are provided. Then, a plurality of demodulators are set in accordance with the number, and after each demodulation, a binary data signal as a digital signal and a signal of the program content as an analog signal are separated. The binary signal of the digital signal is
The data is sent to the decoder as it is, and the code number is decoded from the binary signal in conjunction with the computer, and the contents of the channel, genre, and subdivision are read.

On the other hand, the analog signal of the program content is sent to a storage device after being converted from an analog signal to a digital signal by an A / D converter and converted into an analog signal.
A plurality of demodulators may be provided in accordance with the number of the demodulators. However, in order to reduce the size of the device, one storage device corresponds to the plurality. Therefore, when converting an analog signal from a demodulator to a digital signal, a multiplexing process of sequentially converting a plurality of channels at a speed faster than the analog signal is performed. For example, the digital signal from the demodulator is time-divided. Once into one signal, and then
The signal is returned to the original signal again based on the signal from the decoder in conjunction with the data, and is sequentially stored in the storage device. As a result, the code number of the binary signal and the program content changed to the digital signal are stored in the storage device in association with each other, and the storage location is determined by the decoder based on the data signal. Classified and managed by computer. This storage medium is desirably a medium that can be randomly accessed, such as an optical disk or a magnetic disk, in the sense that the storage medium can be designated and taken out by a computer during reproduction, which will be described later.

In this storage process, two methods have been proposed. One is to set the capacity of the storage medium as large as possible, and to store the contents of a broadcast program for one day or one day. This is a method of storing the entire range as a week. As described above, this full-range method demodulates all radio waves received from a plurality of channels, separates the signals into digital signals and analog signals, and sends them to a storage device for storage. Since all programs are stored when a genre of a desired program, its subdivision, etc. are designated and taken out, it is excellent in that any search and editing can be performed during reproduction. However, in reality, the storage capacity of a storage device is limited, and the full-range method has a drawback that leads to an increase in the size of the device and a rise in price.Moreover, programs to be stored are limited in advance by genre and sub-classification. Because there are many cases,
As another method, a specification method is adopted in which the contents to be stored are limited by specifying a code number. In this method, the contents of a program to be stored in advance are specified by a computer process before storage, and the specified contents are stored in a storage medium based on the interpretation contents of a decoder. If you want to store only news programs,
A genre code number -00001 is designated, and only the designated news program is stored. According to this,
Although there is a drawback that editing and reproduction cannot be performed later when there is a designation omission, practical advantages such as downsizing of a storage device and provision at a low price are great.

In addition, in order to supplement the storage capacity of the storage device, a method in which a plurality of storage media are stacked or a sub storage device is provided in parallel is also effective. FIG. 5 shows a sub-storage device. When a program of a genre specified in advance is broadcast, one of the two separated signals after demodulation is separated.
The value data signal is sent to a decoder, and the information of the other analog signal is sent to a secondary storage device having a relatively large storage capacity, such as a magnetic tape, and stored therein. Thus, even if the capacity of the storage device is limited, it can be handled by increasing the magnetic tape of the secondary storage device. However, the playback in this case is
Since random access is not possible, it is used only as an auxiliary means.
