Abstract

The present invention relates to a reception device, a reception method, a transmission device and a transmission method for a digital signal including tuning assistant information capable of rapidly presenting one segment broadcasting which can be received, and a program.

Station information acquisition units 111 to 113 acquire station information regarding a station, at least including broadcasting area information which is information of a broadcasting area capable of receiving a broadcast wave from the station which transmits the broadcast wave of arbitrary one segment broadcasting at an arbitrary segment. A station selection unit 117 selects a station of the one segment broadcasting which can be received at a predetermined position as a tunable station which can be tuned using the broadcasting area information, and a tuning control unit 118 performs tuning control in which the one segment broadcasting of the tunable station is tuned. The present invention may be applied to, for example, a portable reception terminal or the like of one seg broadcasting.

Claims

1. A reception device for one segment broadcasting, comprising:

station information acquisition means for acquiring station information regarding a station, the station information at least including broadcasting area information which is information of a broadcasting area capable of receiving a broadcast wave from the station which transmits the broadcast wave of the one segment broadcasting at an arbitrary segment;

storage means for storing the station information;

station selection means for selecting a station of the one segment broadcasting which can be received at a predetermined position as a tunable station which can be tuned using the broadcasting area information; and

tuning control means for performing tuning control in which the one segment broadcasting of the tunable station is tuned.

2. The reception device according to claim 1, wherein the tuning control means displays information of the tunable station, and tunes the one segment broadcasting of a station selected by a user from the display of the information of the tunable station.

3. The reception device according to claim 2, wherein the station selection means selects a station of the one segment broadcasting which can be received in an area selected by a user as a tunable station using the broadcasting area information.

4. The reception device according to claim 2, wherein the tuning control means performs a reception check for checking whether or not one segment broadcasting by the tunable station can be received, and displays information of only the tunable station for which reception of the one segment broadcasting has been checked.

5. The reception device according to claim 1, wherein the tuning control means sequentially tunes the one segment broadcasting of the tunable station.

6. The reception device according to claim 1, wherein the station information further includes an effective period during which the station performs the one segment broadcasting, and

wherein the reception device further includes update means for deleting the station information of which the effective period has elapsed, from among pieces of the station information stored in the storage means and for updating the station information.

7. The reception device according to claim 1, wherein the broadcasting area information is information indicating a position of the station and information indicating a transmission output of the broadcast wave by the station.

8. The reception device according to claim 1, wherein the station information further includes a frequency of one segment broadcasting by the station corresponding to the station information, and

wherein the tuning control means tunes the one segment broadcasting using the frequency included in the station information.

9. A reception method for a reception device of one segment broadcasting, comprising the steps of:

acquiring station information regarding a station, the station information at least including broadcasting area information which is information of a broadcasting area capable of receiving a broadcast wave from the station which transmits the broadcast wave of the one segment broadcasting at an arbitrary segment;

storing the station information;

selecting a station of the one segment broadcasting which can be received at a predetermined position as a tunable station which can be tuned using the broadcasting area information; and

performing tuning control in which the one segment broadcasting of the tunable station is tuned.

10. A program for causing a computer to function as:

station information acquisition means for acquiring station information regarding a station, the station information at least including broadcasting area information which is information of a broadcasting area capable of receiving a broadcast wave from the station which transmits the broadcast wave of the one segment broadcasting at an arbitrary segment;

storage means for storing the station information;

station selection means for selecting a station of the one segment broadcasting which can be received at a predetermined position as a tunable station which can be tuned using the broadcasting area information; and

tuning control means for performing tuning control in which the one segment broadcasting of the tunable station is tuned.

11. A transmission device which is a station, comprising:

station information acquisition means for acquiring station information regarding a station, the station information at least including broadcasting area information which is information of a broadcasting area capable of receiving a broadcast wave from the station which transmits the broadcast wave of the one segment broadcasting at each of one or more arbitrary segments; and

transmission means for transmitting the station information of the station with a representative segment which is one segment of the one or more segments used for one segment broadcasting by the station.

12. The transmission device according to claim 11, wherein the transmission means also transmits the station information of other stations with the representative segment.

13. A transmission method of a transmission device, which is a station for transmitting a broadcast wave of one segment broadcasting at each of one or more arbitrary segments, comprising the steps of:

acquiring station information regarding the station, the station information at least including broadcasting area information which is information of a broadcasting area capable of receiving the broadcast wave from the station; and

transmitting the station information of the station with a representative segment which is one segment of the one or more segments used for one segment broadcasting by the station.

14. A program for causing a computer to function as a transmission device which is a station comprising:

station information acquisition means for acquiring station information regarding a station, the station information at least including broadcasting area information which is information of a broadcasting area capable of receiving a broadcast wave from the station which transmits the broadcast wave of the one segment broadcasting at each of one or more arbitrary segments; and

transmission means for transmitting the station information of the station with a representative segment which is one segment of the one or more segments used for one segment broadcasting by the station.
