Abstract
A radio broadcast receiver comprising: a memory; and a processor that is coupled to the memory, and, when executing a program stored in the memory, performs operations. The operations include: receiving analog quality information indicating a reception quality of an analog radio based on a broadcast radio including a digital radio and the analog radio; and determining switching of a radio source from one of the broadcast radio and an IP radio to the other of the broadcast radio and the IP radio based on the analog quality information indicating the reception quality of the analog radio.

A radio broadcast receiver comprising:
- a memory;
- a processor that is coupled to the memory, and, when executing a program stored in the memory, performs operations comprising:
- receiving analog quality information indicating a reception quality of an analog radio based on a broadcast radio including a digital radio and the analog radio;
- determining switching of a radio source from a first one of the broadcast radio and an Internet Protocol (IP) radio to a second one of the broadcast radio and the IP radio based on the analog quality information indicating the reception quality of the analog radio;
- switching the radio source from the IP radio to the broadcast radio in a case in which a reception condition of the analog radio is determined to be good based on the analog quality information;
- switching the radio source from the IP radio to the digital radio in a case in which the reception condition of the analog radio is determined to be good based on the analog quality information while the IP radio is selected as the radio source;
- and
- switching the radio source from the digital radio to the IP radio in a case in which the reception condition of the analog radio is determined not to be good based on the analog quality information while the digital radio of the broadcast radio is selected as the radio source;
- and
- a speaker that, in operation, outputs a broadcast radio sound or an IP radio sound according to the switching,
- wherein the processor, in operation, determines the reception condition of the analog radio is good when a numerical value of a signal level of the analog radio continues to exceed a first threshold value for a first period of time, and
- wherein the processor, in operation, determines the reception condition of the analog radio is not good when the numerical value of the signal level of the analog radio continues to fall below a second threshold value for a second period of time, the second threshold value being lower than the first threshold value.

A radio source switching method comprising:
- receiving analog quality information indicating a reception quality of an analog radio based on a broadcast radio including a digital radio and the analog radio;
- determining switching of a radio source from a first one of the broadcast radio and an Internet Protocol (IP) radio to a second one of the broadcast radio and the IP radio based on the analog quality information indicating the reception quality of the analog radio;
- switching the radio source from the IP radio to the broadcast radio in a case in which a reception condition of the analog radio is determined to be good based on the analog quality information;
- switching the radio source from the IP radio to the digital radio in a case in which the reception condition of the analog radio is determined to be good based on the analog quality information while the IP radio is selected as the radio source;
- and
- switching the radio source from the digital radio to the IP radio in a case in which the reception condition of the analog radio is determined not to be good based on the analog quality information while the digital radio of the broadcast radio is selected as the radio source;
- and
- outputting a broadcast radio sound or an IP radio sound from a speaker according to the switching
- wherein the reception condition of the analog radio is determined to be good when a numerical value of a signal level of the analog radio continues to exceed a first threshold value for a first period of time, and
- wherein the reception condition of the analog radio is determined not to be good when the numerical value of the signal level of the analog radio continues to fall below a second threshold value for a second period of time, the second threshold value being lower than the first threshold value.
