Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a broadcast communication system capable of receiving one of broadcasts from a plurality of broadcast stations by an unspecified number of receivers.

[0002]

[Prior art]

 Generally, in radio broadcasting and television broadcasting, one frequency or one channel is given to one broadcasting station, and one program is broadcast from one broadcasting station. The viewer selects a frequency from a broadcast program by dialing, or selects a program of one broadcasting station by channel selection and receives the broadcast.

[0003]

[Problems to be solved by the invention]

 In the conventional broadcasting described above, only one program is broadcasted from one broadcasting station, and the programs that the viewer can select are limited. On the other hand, if the number of broadcasting stations in an area where broadcasting can be received increases, the number of keys increases with one key operation corresponding to the broadcasting station, and when selecting by manual dial, the target broadcasting station is easily selected. There was a problem that could not be done.

[0004] The present invention has been made in view of the above problems. Even when a single broadcast station can broadcast a plurality of programs at the same time, and there are many broadcast stations and broadcast programs in a certain area, the purpose and purpose of the invention are as follows. It is an object of the present invention to provide a broadcast communication system capable of easily receiving a broadcast.

[0005]

[Means for Solving the Problems]

 The broadcast communication system according to the present invention is a broadcast communication system capable of receiving one of the broadcasts from a plurality of broadcast stations by an unspecified number of receivers. Each broadcast station has one or more frequencies, A code number corresponding to the frequency is set, and the unspecified receiver designates the set code number of the broadcasting station by a combination input of a numeric key and / or a character key to receive a desired broadcast. ing.

In this broadcasting communication system, one or more frequencies and a code number corresponding to the frequency are set in a certain broadcasting station. Therefore, the broadcasting station can simultaneously broadcast a plurality of programs in a given frequency range. The viewer inputs the code number of the broadcast station that he / she wants to watch by operating the numeric keys or character keys, and the receiver automatically tunes to the frequency of the program of the code number and performs the broadcast. Receive.

The mobile phone with a broadcast receiving function according to the second invention has a receiving function as an unspecified receiver according to the first invention, and includes a means for switching between broadcast reception and a telephone call. By switching to the broadcast reception mode, radio broadcasts, television broadcasts, etc. can be received.

[0008]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in more detail with reference to embodiments. FIG. 1 is a schematic diagram illustrating a broadcast communication system according to an embodiment of the present invention. Multiple stations 1_-1, ......, 1_-3The transmitting unit 2 has a plurality of frequencies assigned and set in advance, and transmits a broadcast wave using the assigned frequencies._-1, ..., 2_-11, ..., 2 _-2n It has. In addition, these broadcasting stations 1_-1, 1_-2, 1_-3A code number is assigned to each frequency set with. The code number may be, for example, a three digit number, or a letter, or a mixture of numbers and letters. Broadcasting station 1_-1Transmission section 2_-1Code number is 125, broadcasting station 1_-2Transmission part 2_-11The code number is 361, broadcasting station 1_-3Transmission part 2_{-twenty two}Is like 915. In the case of letters, it is Ao, Eike, Sasina, etc.

[0009] Each broadcasting station 1 _-1, 1 _-2, 1 _-3 each transmission unit 2 _-1, ..., broadcast from 2 _-2n, each antenna 3 _-1, ..., from 3 _-2n Output by radio waves. Ultra high frequency is used for the broadcast frequency, but other frequency bands may be used. The receivers 4 ₋₁ ,..., 4 _−m possessed by an unspecified number of viewers select a desired broadcast from among many radio waves received from the antennas 5 _{−1 ,.} It has an auto tuning function. Input of program selection in the receivers 4 _-1 , 4 _-2 ,..., 4- _m is performed by inputting numbers or characters.

[0010] In the broadcast communication system, the broadcasting station 1 _-1, 1 _-2, 1 _-3, each lot of programs on a plurality of different frequencies are broadcast. Viewer, if you want to watch a program from the transmission unit 2 _-1 of the broadcasting station 1 _-1 therein, the numeric keys, for example "1", "2", by operating the "5", the the receiver 125 of the code number of the program, that is, automatic tuning to the frequency of the broadcast program from the transmission unit 2 _-1 of the broadcast station 1 _-1. Of course, simultaneous viewing on other receivers is naturally possible.

The receiver used in the above embodiment is a dedicated device having a numeric key or a character key for inputting a code program. As shown in FIG. 2, an antenna 11 and a speaker (microphone) are used. A) In addition to the display 12 and the display 13, a portable telephone 15 having a numeric keypad 14 for inputting a telephone number may be provided with a receiving function of the above-described broadcast communication system. In this case, switching to the radio reception mode is performed by operating the radio key 16. The input of the code number of the program at the time of the radio reception is also performed by using the ten keys 14.

[0012] Such a mobile phone can be used for ordinary calls and can receive traffic information, weather forecasts, and other broadcasts at any time, which is convenient. As another form of the receiver, a personal computer may be provided with a broadcast receiving function as shown in FIG. In this case, the input of the code number may be performed by using the numeric keys or the character keys of the keyboard 17. The received broadcast message and the receiving screen may be displayed on the display 18.

[0013]

[Effect of the invention]

 According to the invention of claim 1, each broadcasting station is set with one or more frequencies and a code number corresponding to the frequency, and an unspecified receiver is set with the code number of the broadcasting station. Is specified by a combination of numeric keys and / or character keys to receive the desired broadcast, so that each broadcast station can broadcast multiple programs simultaneously, and the receiver can A desired program can be easily extracted.

According to the second aspect of the present invention, a call function and a broadcast receiving function are provided, and a code number of a broadcast program can also be used as a key for inputting a telephone number, so that an increase in cost can be reduced. This is very convenient because the user can also watch the broadcast when desired.
