  • Patent number: 8495698
    Abstract: A method of intelligently degrading the quality of content, such as video clips and music, stored on a mobile device over time. The method takes into account the probability of a user watching each item of content and either encodes the content at a lower bit-rate, or under certain circumstances, restores the content to its original quality by side-loading the content from a network content store. The bit-rate at which the content is to be encoded is linked to the probability of a piece of content being watched. If the probability of an item of content being watched is high, then the item is stored at a high bit-rate, and conversely, for low probabilities of watching, a low bit-rate is used. If required, in order to restore an item to a higher bit rate, the original high bit rate item can be requested from a network content store. The aim being to store as much content as possible in a given finite memory, but to ensure that content which is likely to be watched is not degraded.

  • Publication number: 20120284367
    Abstract: A method relates to side-loading content onto a mobile device, preferably using a WiFi connection, from a network content store and storing it on the device for viewing later. The method automatically determines when to delete stored content, and more importantly, what content should be transferred over the network in the first instance. The system comprises a content manager which takes into account various parameters to determine what should be transferred and, if required, what should be deleted from the device. The parameters used include user profiles, size of a potential download, as well as available storage space on the device and the predicted duration the device will be in range of a wireless hotspot or broadcast network.

  • Publication number: 20090116443
    Abstract: This invention relates to maintaining or re-establishing a communications session in a wireless communications system. The present invention provides a method of re-routing a call between a user device and a third party device, the method comprising: setting up a call with the third party device using a first wireless connection between the user device and an access point; monitoring a quality parameter of the first wireless connection at the access point; automatically re-routing the call from the third party device to the user via a second wireless connection between the user device and a base station in response to determining that the quality parameter of the first wireless connection has fallen below a predetermined threshold.
