Abstract
Selection of a program in a DAB receiver is facilitated. There are provided a data table 31 containing sets of a service ID and a time data indicating a broadcast time of that program in order of the time as well as a data table 32 containing the service ID in order of receiving frequency of that program. When an operation for selecting a program is performed, it is checked whether or not a data coincident with a service ID of a program of the latest broadcast time among data of the data table 31 is found in the data table 32. As a result of this check, if it is found, a program of that service ID is selected. As a result of the check, if it is not found, the same processing is thereafter repeated to select a program, with a service ID of a program of the next latest broadcast time among data of the data table 31.
Claims3
A receiver comprising:
- a first data table containing sets of a service ID and a time data indicating a broadcast time of a program in order of the time;
- and
- a second data table containing said service ID in order of a receiving frequency of its program, wherein
- when an operation for selecting a program is performed, it is checked whether a data coincident with a service ID of a program of the latest broadcast time among data of said first data table is found in said second data table,
- as a result of this check, if it is not found, the same processing is thereafter repeated to select a program, with a service ID of a program of the next latest broadcast time among data of said first data table,
- a third data table containing sets of said service ID and a program type, wherein
- when an operation for selecting a program is performed, it is checked whether a data coincident with a program type of a program of the highest receiving frequency among data of said second data table is found in said third data table,
- as a result of this check, if it is found, a program of a service ID forming a set with a program type is selected, and
- as a result of said check, if it is not found, the same processing is thereafter repeated to select a program, with a program type of a program of the next highest receiving frequency among data of said second data table.

- and
- a second data table containing said service ID in order of a receiving frequency of its program, wherein
- when an operation for selecting a program is performed, it is checked whether a data coincident with a service ID of a program of the latest broadcast time among data of said first data table is found in said second data table,
- as a result of this check, if it is found, a program of that service ID is selected, and
- as a result of said check, if it is not found, the same processing is thereafter repeated to select a program. with a service ID of a program of the next latest broadcast time among data of said first data table, a third data table containing sets of said service ID and a program type, wherein
- as a result of this check, if it is found, a program of a service ID forming a set with that program type is selected, and
- as a result of a said check, if it is not found, the same processing is thereafter repeated to select a program, with a program type of a program of the next highest receiving frequency among data of said second data table, and wherein
- it is checked whether or not a data coincident with a service ID of the closest time to the present time among data of said first data table is found in said third data table,
- as a result of this check, if it is found, a program of the service ID is selected, and
- as a result of said check, if it is not found, the same processing is thereafter repeated to select a program, with a service ID of a program of the next closest time among data of said first data table.
