摘要： A method and apparatus is described to achieve a fast service change. The method includes: receiving a plurality of transport streams at a client device, each transport stream including a plurality of encrypted services; decrypting an encrypted service from the plurality of encrypted services thereby forming a decrypted service; playing out the decrypted service; storing a portion of at least one encrypted service from the plurality of encrypted services in a storage device; receiving a request for displaying a different encrypted service; identifying a stored portion of the different encrypted service; decrypting the stored portion of the different encrypted service thereby forming a decrypted stored portion; playing out the decrypted stored portion of the different encrypted service at a faster than real time speed; storing a subsequent portion of the different encrypted service in the storage device, the subsequent portion corresponding to a subsequent portion of the different encrypted service received during the decrypting of the stored portion and the playing out the decrypted stored portion of the different encrypted service; decrypting the subsequent stored portion of the different encrypted service thereby forming a decrypted subsequent portion; and playing out the decrypted subsequent portion of the different encrypted service for display upon completion of the playing out of the decrypted stored portion.

摘要： A method of detecting periodic activity patterns associated with the viewing of audio video content is described. The method includes: recording activity data in an activity log; suppressing the activity log one or more times to suppress non-relevant activity data thereby producing one or more sets of suppressed activity data; passing the one or more sets of suppressed activity data through a signal processing function to convert the one or more sets of suppressed activity data to one or more frequency responses; and analysing the one or more frequency responses to detect the periodic activity patterns. Related apparatus and methods are also described.
