Abstract:
1. A method of data management on a mobile device, said mobile device having a plurality of media files stored therein, said method comprising for each stored media file: estimating a probability of a user watching said stored media file; calculating a bit-rate at which to encode said stored media file in dependence on the determined probability; determining whether the calculated bit-rate is less than or greater than the current bit-rate of the stored media file, and if the calculated bit-rate is less than the current bit-rate, then transrating the stored media file to the calculated bit-rate and storing the transrated file on the mobile device, otherwise if the calculated bit-rate is greater than the current bit-rate, then requesting the download of a media file having a higher bit-rate then the current bit-rate of the stored media file from a network content store.
