Abstract

Determining and hiding a replaceable period of a MP (Media Presentation). A method for determining includes receiving a first MPD (Media Presentation Description) that identifies a predetermined period and at least one media segment of the MP to be presented during the predetermined period. A determination is made as to whether the first MPD includes additional data to be resolved by an application. The additional data is provided to the application when the first MPD is determined to include the additional data. Additional period information is received from the application. A second MPD is generated based on the received additional period information. The MP is output for display to a user based on the second MPD. Each of a subset of the at least one media segment for a replaceable sub-period of the MP is replaceable with an alternate media segment.

5. The method according to claim 1, wherein at least one parameter included in the additional period information is encrypted in the additional data.

6. The method according to claim 1, wherein the additional data is tagged by an XLink for the predetermined period of the first MPD.

7. The method according to claim 1, further comprising:

receiving a digital television signal that includes the first MPD and the at least one media segment of the first MPD, and

downloading the application from the received digital television signal or based on information included in the received digital television signal.

8. A reception apparatus, comprising:

circuitry configured to

receive a first MPD (Media Presentation Description), the first MPD identifying a predetermined period and at least one media segment of a MP (Media Presentation) to be presented during the predetermined period;

determine whether the first MPD includes additional data to be resolved by an application;

provide the additional data to the application when the first MPD is determined to include the additional data;

receive additional period information from the application, the additional period information being determined by the application based on the additional data included in the first MPD and identifying a replaceable sub-period within the predetermined period identified by the first MPD;

generate a second MPD based on the additional period information received from the application; and

output the MP for display to a user based on the second MPD, each of a subset of the at least one media segment for the replaceable sub-period of the MP being replaceable with an alternate media segment,

wherein the second MPD identifies at least one media segment that is not included in the first MPD.

9. The reception apparatus according to claim 8, wherein the replaceable sub-period represents one or more advertisement slots in the MP that are replaceable.

10. The reception apparatus according to claim 8, wherein the second MPD identifies the alternate media segment that replaces one of the at least one media segment identified in the received first MPD.

11. The reception apparatus according to claim 8, wherein

the additional period information includes a period start time and/or a segment start number for the replaceable sub-period, and

the replaceable sub-period replaces a portion of the predetermined period.

12. The reception apparatus according to claim 8, wherein at least one parameter included in the additional period information is encrypted in the private data.

13. The reception apparatus according to claim 8, wherein the additional data is tagged by an XLink for the predetermined period of the first MPD.

14. The reception apparatus according to claim 8, wherein the circuitry is further configured to:

receive a digital television signal that includes the first MPD and the at least one media segment of the first MPD, and
