Abstract

Methods and apparatuses for selectively displaying a video program are disclosed. A system for selectively displaying a video program in accordance with the present invention comprises a transmission station, including a server for attaching information to the video program, a plurality of satellites receiving at least an uplink signal which includes the information and the video program from the transmission station and producing a downlink signal based on the uplink signal, an antenna, the antenna receiving the downlink signal, and at least one receiver, coupled to the antenna, for receiving the downlink signal and interpreting the information in the downlink signal, wherein the at least one receiver selectively displays the video program based on at least the interpreted information.

Claims

1. A method for selectively executing an interactive application associated with a stream of a program comprising at least one of a video stream and an audio stream transmitted on at least one of a plurality of channels, comprising:

receiving a tuning command at a receiver to tune to the at least one of the plurality of channels;

intercepting the tuning command with an Application Programming Interface (API);

determining an interactive application type of the interactive application, the interactive application type including a first interactive application type and a second interactive application type;

if the determined interactive application type is the first interactive application type;

providing the program of the stream to an output of the receiver before executing the interactive application and without inhibition by the interactive application; and

executing the interactive application;

if the determined interactive application is the second interactive application type;

executing the interactive application;

querying the API with the executing interactive application, the query comprising at least an authorization status query related to the executing interactive application;

determining the authorization status of the stream based at least in part on a result of the query; and

selectively providing the program of the stream to the output of the receiver based at least in part on the authorization status.

2. The method of claim 1, wherein the stream further comprises a flag indicating that the program of the stream is to be provided to the output of the receiver only after the authorization status is determined.

3. The method of claim 1, wherein the program comprises a mosaic of a plurality of video feeds, and the interactive application is the second interactive application type.

4. The method of claim 3, wherein each video feed in the plurality of video feeds has an authorization status separate from the other of the video feeds and each video feed in the plurality of video feeds is selectively provided for display based on the separate authorization status according to the interactive application.

5. The method of claim 4, wherein the separate authorization status is based on a geographical location of the receiver.

6. The method of claim 4, wherein the separate authorization status is based on a service authorization of the receiver.

7. The method of claim 4, further comprising determining at least one interactive function of the video feeds based on the authorization status of the video feeds.

15. The method of claim 1, wherein:

the interactive application type is flagged according to the selected channel.

8. An apparatus for selectively executing an interactive application associated with a stream of a program comprising at least one of a video stream and an audio stream transmitted on at least one of a plurality of channels, comprising:

a receiver, comprising;

a tuner, for receiving a tuning command to tune the at least one of the plurality of channels; and

an application programming interface (API) for intercepting the tuning command, for determining an interactive application type of the interactive application and for providing the stream according to the interactive application type, the API permitting provision the program of the stream to an output of the receiver before execution of the interactive application and without inhibition by the interactive application if the interactive application type is the first application type and executing the interactive application before provision of the program of the stream to the output of the receiver if the interactive application is the second application type;

wherein the executed interactive application queries the API for an authorization result related to the executing interactive application, determines the authorization status of the stream based at least in part on the authorization result, and selectively provides the stream based at least in part on the authorization result.

9. The system of claim 8, wherein the stream comprises information indicating that the stream is authorized to be provided only after the authorization status of the stream is determined.

10. The system of claim 9, wherein the program comprises a mosaic of a plurality of video feeds, and the interactive application is the second interactive application type.

11. The system of claim 10, wherein each video feed in the plurality of video feeds has an authorization status separate from the other of the video feeds and each video feed in the plurality of video feeds is selectively provided for display based on the separate authorization status according to the executing interactive application.

12. The system of claim 11, wherein the separate authorization status is based on a geographical location of the receiver.

13. The system of claim 11, wherein the separate authorization status is based on a service authorization of the receiver.

14. The system of claim 13, wherein the receiver determines at least one interactive function of the at least one video program based on the authorization status of the video feed.

16. The apparatus of claim 8, wherein:

the interactive application type is flagged according to the selected channel.
