The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An HD radio receiver that uses an existing analog broadcast frequency and receives a hybrid terrestrial digital radio broadcast which transmits a digital signal simultaneously with an analog broadcast, the HD radio receiver comprising:
a storage unit for carrying out tuning at a time when autostore is activated, and for storing broadcasting station data about a terrestrial digital radio broadcast received by the tuning;
a reception quality detecting unit for detecting reception quality of the radio broadcast received; and
a control unit for deciding a number of broadcast programs of multicasting that broadcasts a plurality of programs on a single frequency from the terrestrial digital radio broadcast received, and for registering in the storage unit broadcasting station data with a greater number of decided broadcast programs in preference to broadcasting station data with better reception quality detected by the reception quality detecting unit.
2. The HD radio receiver according to claim 1, wherein
the control unit registers in the storage unit the broadcasting station data with the greater number of broadcast programs of the multicasting in descending order of the reception quality detected by the reception quality detecting unit, and when the number of the registered broadcasting station data is less than a maximum number of registration in the storage unit, the broadcasting station data including the analog broadcast is registered in descending order of the reception quality as the remainder of the registration.
3. An autostore control method in an HD radio receiver that includes at least an operation unit, a control unit, and a storage unit, that monitors reception quality under control of the control unit, that has an autostore function of automatically registers receivable broadcasting station data in the storage unit by carrying out tuning, and that receives a hybrid terrestrial digital radio broadcast which transmits a digital signal simultaneously with an analog broadcast using an existing analog broadcast frequency, the autostore control method of the HD radio receiver comprising:
a step of carrying out tuning while the control unit alters the receiving frequency successively at a time when autostore is activated through the operation unit;
a step of registering, when a radio broadcast received at each tuning has prescribed reception quality, the reception quality in the storage unit by the control unit;
a step of making, when the control unit makes a decision as to whether the radio broadcast received by the tuning includes a digital broadcast and when the digital broadcast is included, a further decision of a number of broadcast programs of multicasting that broadcasts a plurality of programs on a single frequency; and
a step of registering in the storage unit the broadcasting station data with a greater number of broadcast programs decided by the control unit in preference to the broadcasting station data with better reception quality.
