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 for managing a plurality of subscriptions on a wireless media presentation device, the method comprising:

receiving an indication of a service memory requirement for each current subscription on the wireless media presentation device, the service memory requirement being based on an 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 a capacity of memory in the wireless media presentation device for storage of presentations;

determining a service memory requirement for each current subscription on the wireless media presentation device;

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

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

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

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

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

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

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

6. The method as set forth in claim 5, wherein the determining the service memory requirement for the additional subscription is performed by the server.

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

receiving an indication of the service memory requirement for the additional subscription at the wireless media presentation device.
