Abstract

Claims (74)

1. A method comprising:

via a channel change controller:

detecting a channel identifier indicating a channel for a program content;

responsive to an indication of a high bandwidth permission, said high bandwidth permission indicated in a state identifier, said high bandwidth permission assigned for a terminal equipment by a permission controller, determining a high bandwidth IP address for said detected channel identifier, said high bandwidth IP address joined via a network layer joining protocol and adapted to receive a high bandwidth content of said channel via said network layer joining protocol;

responsive to no indication of said high bandwidth permission, via a permission requester, requesting said high bandwidth permission from said permission controller; and

joining a standard bandwidth IP address to receive standard bandwidth content of said channel wherein said requesting is started a predetermined time after said joining.

2. The method of claim 1 , wherein:

said requesting is started after a predetermined time.

3. The method of claim 1 , further comprising:

checking metadata linked to said standard bandwidth content;

responsive to an indication that said metadata does not refer to high bandwidth content, stopping said requesting.

4. The method of claim 1 , further comprising:

checking whether said high bandwidth IP address is available for said detected channel identifier;

responsive to an indication that no high bandwidth IP address is available, stopping said requesting.

5. The method of claim 1 , further comprising:

checking whether said high bandwidth permission is available in a subscriber account including said terminal equipment;

responsive to an indication that said high bandwidth permission is not available, stopping said requesting.

6. The method of claim 1 , wherein:

responsive to a request for high bandwidth permission from said terminal equipment, said permission controller decrements a counter, said counter counting a number of high bandwidth permissions predetermined for each subscriber account.

7. The method of claim 1 , further comprising:

responsive to a request for high bandwidth permission from said terminal equipment, performing a user confirmation, wherein, responsive to said user confirmation, said state identifier is changed to a high bandwidth allowed state.

8. The method of claim 1 , wherein:

responsive to a user confirmation, said joining of said high bandwidth IP address is directly performed.

9. The method of claim 1 , wherein:

responsive to a change in said state identifier to a high bandwidth allowed state, proceeding to said detecting.

10. The method of claim 1 , wherein:

said program content is provided by multicast data streams.

11. The method of claim 1 , wherein:

said program content is provided by unicast data streams.

12. The method of claim 1 , wherein:

said requesting constitutes a permission reservation for reservation of a high bandwidth permission for a predetermined time.

13. The method of claim 1 , wherein:

said requesting includes priority information related to said terminal equipment, wherein, responsive to a determination that a second priority is higher than a first priority, said permission controller is adapted to revoke a first high bandwidth permission from a first terminal equipment with a first priority and enable a second high bandwidth permission for a second terminal equipment with a second priority.

14. The method of claim 1 , wherein:

responsive to an indication that said terminal equipment is in sleep mode, said high bandwidth permission is revoked.

15. The method of claim 1 , wherein:

responsive to an indication that said terminal equipment has been in standard bandwidth mode for a predetermined time, said high bandwidth permission is revoked.

16. A computer program product comprising a non-transitory computer-readable medium storing computer readable program portions adapted for causing a processor to execute the method steps according to claim 1 .

17. An apparatus comprising:

a channel change controller adapted to detect a channel identifier indicating a channel for a program content;

a state manager adapted to check a state identifier indicating a high bandwidth permission assigned for a terminal equipment by a permission controller;

a permission requester adapted to make a permission request for said high bandwidth permission from said permission controller;

an IP-database adapted to map a plurality of available high and standard bandwidth IP addresses with said channel identifier;

a network layer joining protocol adapted for joining an IP address, wherein responsive to an indication of said high bandwidth permission, said channel change controller determines a high bandwidth IP address for said detected channel identifier and said network layer joining protocol joins to said determined high bandwidth IP address, and responsive to an indication of no high bandwidth permission, said permission requester requests said high bandwidth permission from said permission controller; and

a timer adapted to generate a trigger signal for initiating a request of said permission requester after said network layer joining protocol joins a standard bandwidth IP address for a predetermined time.

18. The apparatus of claim 17 , wherein

said network layer joining protocol joins a standard bandwidth IP address to receive a standard bandwidth content of said channel.

19. The apparatus of claim 17 , wherein:

said network layer joining protocol joins a standard bandwidth IP address to receive a standard bandwidth content of said channel;

responsive to an indication that metadata delivered by said standard bandwidth IP address do not refer to high bandwidth content, said permission requester does not make said permission request.

20. The apparatus of claim 17 , wherein:

said permission requester checks whether said high bandwidth IP address is available for said detected channel identifier;

responsive to an indication that said high bandwidth IP address is not available, said permission requester does not make said permission request.

21. The apparatus of claim 17 , wherein:

said permission requester checks whether said high bandwidth permission is available in a subscriber account including said terminal equipment;

responsive to an indication that said high bandwidth permission is not available, said permission requester does not make said permission request.

22. The apparatus of claim 17 , wherein:

responsive to a receipt of said high bandwidth permission for said terminal equipment, said permission requester asks for a user confirmation, and wherein, responsive to said user confirmation, said state manager changes said state identifier to a high bandwidth allowed state.

23. The apparatus of claim 17 , wherein:

responsive to a user confirmation said network layer joining protocol joins said high bandwidth IP address directly.

24. The apparatus of claim 17 , wherein:

said program content is provided by multicast data streams.

25. The apparatus of claim 17 , wherein:

said program content is provided by unicast data streams.

26. The apparatus of claim 17 , wherein:

said permission requester performs a permission reservation for reservation of a high bandwidth permission for a predetermined time.

27. The apparatus of claim 17 , wherein

said permission request comprises priority information related to said terminal equipment, wherein, responsive to a determination that a second priority is higher than a first priority, and wherein said permission controller is adapted to revoke a first high bandwidth permission from a first terminal equipment with a first priority and enable a second high bandwidth permission for a second terminal equipment with a second priority.

28. The apparatus of claim 17 , wherein:

responsive to an indication that said terminal equipment is in sleep mode, said high bandwidth permission is revoked.

29. The apparatus of claim 17 , wherein:

responsive to an indication that said terminal equipment has been in standard bandwidth mode for a predetermined time, said high bandwidth permission is revoked.

30. The apparatus of claim 17 , wherein:

said apparatus is a set top box.
