Abstract: There is disclosed a method of processing a video stream, comprising: performing a content analysis of the video stream; identifying a transition from one segment to another segment in the video stream based on the content analysis; and marking a segment boundary corresponding to the identified transition.

Abstract: 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.

Abstract: 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.

Abstract: A method for resolving ambiguities in natural language by organizing the task into multiple iterations of analysis done in successive levels of depth. The processing is adaptive to the users' need for accuracy and efficiency. At each level of processing the most accurate disambiguation is made based on the available information. As more analysis is done, additional knowledge is incorporated in a systematic manner to improve disambiguation accuracy. Associated with each level of processing is a measure of confidence, used to gauge the confidence of a process in its disambiguation accuracy. An overall confidence measure is also used to reflect the level of the analysis done.
