Access to content

1. A method of establishing access to content at a user device, the method comprising the steps, at the user device, of:

providing an identifier, the identifier linked to a future condition;

accessing a catalogue of available content based on the identifier;

receiving a list of content identifiers from the catalogue, wherein the list comprises content identifiers of content which meet the future condition;

selecting at least one content identifier from the catalogue;

downloading content associated with the at least one selected content identifier to the user device;

preventing access to the downloaded content at the user device, prior to the occurrence of the future condition:

responsive to detecting a condition corresponding to the future condition, and an indication that the user device is located in a controlled environment, triggering access at the user device to the downloaded content associated with the at least one content identifier, wherein:

the controlled environment limits communications with the user device;

the future condition comprises at least one of an association with a time window, a condition of the state of the user device, and a condition for the rights to access the downloaded content; and

the triggering further comprises matching the future condition as indicated by the identifier to a current condition as recognized by the user device; and

maintaining access at the user device to the downloaded content in dependence on the condition being maintained, wherein if the condition corresponding to the future condition is no longer met at the user device, access to the downloaded content is prevented at the user device.

2. The method of claim 1 , further comprising:

triggering access to the content in dependence on a time window.

3. The method of claim 2 , wherein the time window is associated with a further condition being a rights condition, and the step of triggering access to the content is dependent on matching a current time to a time window of the rights condition.

4. The method of claim 1 , wherein detecting the condition corresponding to the future condition comprises one or more of: detecting the altitude of the user device; detecting the speed of the user device; and detecting connection of the user device to a specific network.

5. The method of claim 1 , wherein the step of triggering access at the user device to the downloaded content comprises one of triggering access at the user device to the downloaded content and triggering access at a further user device to the downloaded content.

6. The method of claim 1 , wherein the condition is a rights condition for the content, wherein the step of triggering further comprises matching the rights condition to a current condition to allow rights permitted access to the content.

7. The method of claim 1 , wherein a current condition is determined from one of a state of the user device and a state of a further user device.

8. The method of claim 1 in which the controlled environment is defined by a controlled journey.

9. The method of claim 1 , wherein the content is video content, and the step of triggering access further comprises selectively allowing access to playout the video content.

10. A user device for establishing access to content, comprising: a user interface configured to:

receive an identifier from a user of the user device, the identifier being linked to a future condition;

access a catalogue of available content based on the identifier;

receive a list of content identifiers from the catalogue, wherein the list comprises content identifiers of content which meet the future condition;

select at least one content identifier from the catalogue; and

download content associated with the at least one selected content identifier to the user device; and

a processor configured to:

prevent access to the downloaded content at the user device, prior to the occurrence of the future condition:

detect a condition corresponding to the future condition and an indication that the user device is located in a controlled environment, and trigger access at the user device to the downloaded content associated with the at least one selected content identifier, wherein:

the controlled environment limits communications with the user device;

the future condition comprises at least one of an association with a time window, a condition of the state of the user device, and a condition for the rights to access the downloaded content; and

the triggering further comprises matching the future condition as indicated by the identifier to a current condition as recognized by the user device; and

maintain access at the user device to the downloaded content in dependence on the condition being maintained, wherein if the condition corresponding to the future condition is no longer met at the user device, the processor is configured to prevent access to the downloaded content at the user device.

11. The user device of claim 10 , wherein the processor is further configured to detect one or more of: the altitude of the user device; the speed of the user device; and connection of the user device to a specific network.

12. The user device of claim 10 , wherein the condition is a rights condition for the content, the user device further being configured to trigger access in dependence on matching the rights condition to a current condition to allow rights permitted access to the content.

13. The user device of claim 10 , further configured to trigger access to the content in dependence on a time window, wherein the time window is associated with a further condition being a rights condition, and the user device is configured to selectively enable the content in dependence on matching a current time to a time window of the rights condition.

14. The user device of claim 10 in which the controlled environment is defined by a controlled journey.
