ことである。The receiver (not shown) learns the name or frequency of the broadcasting station of the desired program through another means such as a newspaper, and at the desired time selects the frequency using the dial knob 4 provided on the reception frequency selection section 3 of the receiver 2. Select the desired broadcasting station using station button 5. however,
Since it is not always possible to find out the broadcasting station of the desired program by other means such as newspapers, or it is troublesome, the receiver generally operates the dial knob 4 or the channel selection button 5 guesswork while listening to the sound. I try to find a station that broadcasts the type of news, weather forecast, road information, etc. that I want. At that time, it is of little concern to the receiver what station the broadcasting station is.

されている。In a broadcast system in which the broadcast program selection device according to the present invention is used, codes indicating the types of programs such as news, weather forecast, traffic information, music, etc. are predefined as conventions. The code indicating the type of each program is multiplexed into the broadcast wave signal as an identification signal and is constantly transmitted from the broadcast station.
なお、識別信号の多重化方法としては、周波数多重１時
分側条重４位相多重、角度多重等の公知の方法を用いて
よい。Note that as a method for multiplexing the identification signals, known methods such as frequency multiplexing, 1-hour side-line multiplexing, 4-phase multiplexing, angle multiplexing, etc. may be used.

周波数掃引部８は掃引動作を停止する。In FIG. 1, when the recipient presses a selection button 12a for selecting, for example, a news program, in the program type setting section 12, an identification signal 13 having a code N, for example, is applied to the program type collation section 14. On the other hand, broadcast wave signals from each broadcast station received by the antenna 6 are applied to the broadcast wave selection section 7. The broadcast wave selection section 7 is frequency-swept by the received frequency sweep section 8 from the low frequency side to the high frequency side or from the high frequency side to the low frequency side at a constant speed, and the broadcast wave signals whose frequencies are selected sequentially are swept. is added to the output display section 9 and sequentially displayed as audio and video. At the same time, the selected broadcast wave signal is applied to the identification signal detection section 10, and the identification signal 11 is detected. This identification signal 11 is compared with the above-mentioned identification signal 13 having the code N in the program type collating section 14. When the code of the detected identification signal 11 becomes N and matches the code N of the identification signal 13, a stop signal 15 is output, and the reception frequency sweep section 8 stops the sweeping operation.
従って、放送波選択部７はニュース番組を放送している
放送波信号の周波数に固定され、以障はその放送波信号
の受信が継続して行われることになる。Therefore, the broadcast wave selection section 7 is fixed to the frequency of the broadcast wave signal broadcasting the news program, and the reception of the broadcast wave signal is continued.

効果が得られる。As described above, according to the present invention, a broadcast wave signal in which an identification signal indicating the type of broadcast program is multiplexed is received while sweeping the reception frequency, and the identification signal is detected from the received broadcast wave signal. When the received identification signal matches the preset identification signal, the above reception frequency sweep is stopped, so instead of selecting a broadcasting station by frequency as in the past, it is possible to directly select a broadcasting station by program type. you can choose,
As a result, the receiver can easily and quickly receive the program he or she wishes to receive by simply operating a selection button or the like.
