Abstract: To avoid discontinuities when resuming play of a digital stream that was paused while being viewed live and being simultaneously recorded, the timestamp and digital stream time base discontinuity count associated with the last-viewed frame are used to access the frame in storage that has the same discontinuity count (indicating that it is in the same segment as the last-viewed frame) and a timestamp one greater than the timestamp of the last-viewed frame.

Abstract: To avoid discontinuities when resuming play of a video stream that was paused while being viewed live and being simultaneously recorded, the timestamp and video stream time base discontinuity count associated with the last-viewed frame are used to access the frame in storage that has the same discontinuity count (indicating that it is in the same segment as the last-viewed frame) and a timestamp one greater than the timestamp of the last-viewed frame.

Abstract: According to one embodiment of the invention, feeder logic is implemented as a software program stored in a machine readable medium and executed by a processor. The feeder logic is adapted to access indexing data associated with a pre-stored data unit. The pre-stored data unit including content in a scrambled format. The feeder logic is further adapted to generate a trigger data sequence and to insert the trigger data sequence into a data stream processed by a descrambler in response to detection that the content in the scrambled format cannot be descrambled by the descrambler using a currently valid descrambling key. The trigger data sequence is inserted prior to scrambled content of the pre-stored data unit to be processed.
