Abstract

Media distribution systems may include methods and apparatus to perform memory management on a wireless devices configured to receive non-real time portions of media services. Such methods and apparatus may be based upon an allowable capacity of presentations storable in device memory, as well as on a required memory associated with each presentation in a media service. Such methods and apparatus allow a device to subscribe to a media service based upon sufficient available memory in the device to support the service.

Claims

1. A method more managing a plurality of subscription on a media presentation device, the method comprising:

determining a capacity of memory in a media presentation device for storage of presentations;

determining a service memory requirement for each current subscription on the media presentation device, the service memory requirement being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription;

determining an amount of available memory on the media presentation device based on the capacity of memory and a sum of the service memory requirements for each current subscription on the media presentation device;

determining a service memory requirement for an additional subscription, the service memory requirement for an additional subscription being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription; and

subscribing the media presentation device to receive the additional subscription when the service memory requirement for an additional subscription is less than or equal to the amount of available memory.

2. A method, as set forth in claim 1, wherein the service memory requirement of a subscription is determined using a contact window start time associated with each scheduled presentation in the subscription, a viewing time associated with each scheduled presentation in the subscription, and a size of the presentations in the subscription.

3. A method, as set forth in claim 1, wherein the service memory requirement of a subscription is determined based on a preset number of concurrently storable presentations for a subscription.

4. A method, as set forth in claim 1, wherein the step of determining an of amount of available memory is performed by the media presentation device.

5. A method, as set forth in claim 4, further comprising:

transmitting, from the media presentation device to a server, a request to subscribe to the proposed subscription along with an indication of the amount of available memory.

6. A method, as set forth in claim 5, wherein the step of determining a service memory requirement for an additional subscription is performed by the server.

7. A method, as set forth in claim 1, further comprising:

transmitting an indication of the service memory requirement for an additional subscription to the media presentation device.

8. A system for managing a plurality of subscription on a media presentation device, the system comprising:

means for determining a capacity of memory in a media presentation device for storage of presentations;

means for determining a service memory requirement for each current subscription on the media presentation device, the service memory requirement being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription;

means for determining an amount of available memory on the media presentation device based on based on the capacity of memory and a sum of the service memory requirements for each current subscription on the media presentation device;

means determining a service memory requirement for an additional subscription, the service memory requirement for an additional subscription being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription; and

means for subscribing the media presentation device to receive the additional subscription when the service memory requirement for an additional subscription is less than or equal to the amount of available memory.

9. A system, as set forth in claim 8, wherein the service memory requirement of a subscription is determined using a contact window start time associated with each scheduled presentation in the subscription, a viewing time associated with each scheduled presentation in the subscription, and a size of the presentations in the subscription.

10. A system, as set forth in claim 8, wherein the service memory requirement of a subscription is determined based on a preset number of concurrently storable presentations for a subscription.

11. A system, as set forth in claim 8, wherein the step of determining an of amount of available memory is performed by the device.

12. A system, as set forth in claim 11, further comprising:

means for transmitting to a server, a request to subscribe to the proposed subscription along with an indication of the amount of available memory.

13. A system, as set forth in claim 12, wherein the means for determining a service memory requirement for an additional subscription comprises a server.

14. A system, as set forth in claim 8, further comprising:

means for transmitting an indication of the service memory requirement for an additional subscription to the media presentation device.

15. A media presentation device comprising:

memory;

a processor; and

a subscription manager that;

determines a capacity of the memory for storage of presentations;

identifies a service memory requirement for each current subscription on the media presentation device, the service memory requirement being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription;

identifies an amount of available memory on the media presentation device based on the capacity of the memory and a sum of the service memory requirements for each current subscription on the media presentation device;

identifies a service memory requirement for an additional subscription, the service memory requirement for an additional subscription being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription; and

generates a subscription request for the additional subscription when the service memory requirement for an additional subscription is less than or equal to the amount of available memory.

16. A media presentation device, as set forth in claim 15, wherein the service memory requirement of a subscription is determined using a contact window start time associated with each scheduled presentation in the subscription, a viewing time associated with each scheduled presentation in the subscription, and a size of the presentations in the subscription.

17. A media presentation device, as set forth in claim 15, wherein the service memory requirement of a subscription is determined based on a preset number of concurrently storable presentations for a subscription.

18. A computer program product comprising:

a computer-readable medium comprising;

at least one instruction for causing a computer to determine a capacity of memory of a media presentation device for storage of presentations;

at least one instruction for causing a computer to identify a service memory requirement for each current subscription on the media presentation device, the service memory requirement being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription;

at least one instruction for causing a computer to identify an amount of available memory on the media presentation device based on the capacity of the memory and a sum of the service memory requirements for each current subscription on the media presentation device;

at least one instruction for causing a computer to identify a service memory requirement for an additional subscription, the service memory requirement for an additional subscription being based on a maximum amount of memory that will be required over the course of a subscription taking into account any overlap in the storage of presentations associated with the subscription; and
