Abstract

The present technology relates to a reception device, data processing method, and a program which make it possible to smoothly switch the output of data in a case where data transmitted via different transmission paths is received to be output.

A reception device includes: a reception unit that receives a plurality of pieces of data separately transmitted via different transmission paths and given time stamps corresponding to each other; an output control unit that selects data to be output from among the plurality of pieces of data and controls a timing of outputting the selected data on the basis of the time stamp of a piece of data having a latest time stamp among the plurality of pieces of data; and an accumulation unit that accumulates at least the plurality of pieces of data given the time stamps later than the time stamp of the data that has been output from among the received plurality of pieces of data. The present technology can be applied to, for example, a reception device of a broadcasting system using MMT.

Claims

1. A reception device comprising:

a reception unit that is electronically connectable to a broadcast station in a manner that permits the reception unit to;

receive packets of data from the broadcast station via a first transmission path,

receive the packets from the broadcast station via a second transmission path that differs from the first transmission path;

wherein the reception device is configured to;

determine a time difference between receipt, by the reception unit, of one of the packets via the first transmission path and via the second transmission path,

inhibit a switching of processing to the packets received via the second transmission path when the reception device determines that the time difference exceeds a threshold value.

2. The reception device according to claim 1, wherein:

the first transmission path is an electronic communication pathway between the broadcast station and the reception unit.

3. The reception device according to claim 2, wherein:

the second transmission path is another electronic communication pathway between the broadcast station and the reception unit.

4. The reception device according to claim 1, wherein:

the device is configured to;

permit the switching of processing to the packets received via the second transmission path when the reception device determines that receipt of the packets by the reception unit is via the first transmission path.

5. The reception device according to claim 4, wherein:

the reception device is configured to;

determine whether or not the reception unit receives the packets via the first transmission path.

6. The reception device according to claim 1, further comprising:

an accumulation unit configured to;

restrict an accumulation amount of the data from the broadcast station via the first transmission path when the time difference exceeds another threshold value.

7. A data processing method comprising:

receiving, by a reception unit that is electronically connectable to a broadcast station, packets of data from the broadcast station via a first transmission path;

receiving, by the reception unit, the packets from the broadcast station via a second transmission path that differs from the first transmission path;

determining, by a reception device that comprises the reception unit, a time difference between the reception unit receiving one of the packets via the first transmission path and the reception unit receiving the one of the packets via the second transmission path; and

inhibiting, by the reception device, a switching of processing to the packets received via the second transmission path when the reception device determines that the time difference exceeds a threshold value.

8. The data processing method according to claim 7, wherein:

the first transmission path is an electronic communication pathway between the broadcast station and the reception unit.

9. The data processing method according to claim 8, wherein:

the second transmission path is another electronic communication pathway between the broadcast station and the reception unit.

10. The data processing method according to claim 7, further comprising:

determining, by the reception device, whether or not the reception unit receives the packets via the first transmission path.

11. The data processing method according to claim 10 wherein:

permitting, by the reception device, the switching of processing to the packets received via the second transmission path when the reception device determines that receipt of the packets by the reception unit is via the first transmission path.

12. The data processing method according to claim 7, further comprising:

restricting, by an accumulation unit, an accumulation amount of the data from the broadcast station via the first transmission path when the time difference exceeds another threshold value.

13. A tangible non-transitory computer-readable storage medium, the computer-readable storage medium is configured to store a program executable by a reception device, the reception device upon execution of the program is configured to perform the data processing method according to claim 7.
