摘要： There is disclosed a technique of associating device activity to a broadcast programme, comprising: receiving a model for a broadcast programme identifying portions of content and portions of breaks in the content; monitoring, via a client software module running on users' mobile devices, said device's active or inactive states; receiving an activity stream of a user device; comparing the activity stream to the model of the broadcast programme to identify a correlation between them; inferring a user of the user device as watching the broadcast programme based on a level of the correlation.

摘要： There is disclosed a technique for providing multimedia content comprising: compressing a multimedia stream; and generating an error correction model for providing an alternative version of the compressed multimedia stream by: decompressing the compressed multimedia stream; determining errors in the decompressed version by comparing to the input multimedia stream; and correcting the errors to minimise the difference between the decompressed version and the input multimedia stream.
