Abstract

With the operation of character select keys, alphanumeric data stored in a ROM are successively read out and latched in a latch circuit under the control of a CPU. The call sign data of a received channel assembled in the latch circuit are stored together with the frequency data of that received channel in a RAM. The call sign data preset in this way is read out from the RAM by taking out the frequency data from the tuner and using it as address means and is visually displayed on a display unit while being informed of as voice by a voice synthesizer.

Claims

1. A broadcast wave receiving system comprising:

a tuner device;

means for storing a plurality of alphanumeric characters;

means for sequentially reading said characters from said storing means;

means for specifying a received channel call sign presetting mode;

means for producing a desired call sign data by successively selecting desired ones of said characters read out by said reading means;

call sign data storage means for successively storing call sign data from said call sign data producing means and received broadcast wave frequency data corresponding to said call sign data when said presetting mode is specified;

means for comparing data corresponding to received broadcast wave frequencies obtained from said tuner device and frequency data stored in said call sign storage means at a time of reception after said successive data storing;

means for reading out a call sign data from said call sign data storage means in response to a frequency data coincidence output of the comparing means; and

means for informing the user of said call sign data.

3. The broadcast wave receiving system according to claim 1 or 2 wherein said means for informing the user of call sign data includes call sign data display means and means for synthesizing voice corresponding to displayed call sign data.

4. The broadcast wave receiving system according to claim 3, wherein said call sign data storage means further stores tuning error data in combination with the received frequency data.

6. The broadcast wave receiving system according to claim 1, which further includes means for generating confirmation data about time, temperature, etc. other than the received broadcast program contents, and at least one data confirming key for causing said informing means to inform of the confirmed data.

2. A broadcast wave receiving system comprising:

a tuner device;

a plurality of character select keys;

a read only memory in which a plurality of alphanumeric data are stored;

means for reading a given alphanumeric data from said read only memory according to the operation of said character select keys;

a key for reducing the speed of reading out data from said read only memory;

means for specifying a received channel call sign presetting mode;

means for producing a desired call sign data by successively taking out a plurality of alphanumeric data from said reading means;

call sign data storage means for successively storing call sign data from said call sign data producing means and received broadcast wave frequency data corresponding to said call sign data when said presetting mode is specified;

means for comparing data corresponding to received broadcast wave frequencies obtained from said tuner device and frequency data stored in said call sign storage means at a time of reception after said successive data storing;

means for reading out a call sign data from said call sign data storage means in response to a frequency data coincidence output of the comparing means; and

means for informing the user of said call sign data.

5. The broadcast wave receiving system according to claim 2 further comprising forward and reverse feed keys for respectively forwardly and reversely reading out the alphanumeric data from said read only memory for one character after another.
