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.
Claims20
A television systems comprising:
- at least one processor associating at least one timestamp of at least one digital data element with at least one discontinuity count;
- wherein
- the timestamp and discontinuity count are used by the processor for resuming play, using data in a storage accessible to the processor, of a digital data stream that was paused and/or bookmarked during live play of the stream.
A method for providing for smooth resumption of play of a digital stream, comprising:
- detecting a “resume play” command;
- using a timestamp and discontinuity count of a paused and/or bookmarked frame, retrieving a frame at least partially based on the frame having a discontinuity count matching the discontinuity count of the paused and/or bookmarked frame;
- and
- synchronizing a discontinuity count in a recording path with a discontinuity count in a decoding path.
(canceled)
A television system, comprising:
- at least one TV display;
- at least one decoder driving the display;
- means for sending a received digital stream having time base discontinuities through the decoder for presentation thereof on the display;
- means for pausing and/or bookmarking the display;
- means for sending a recorded version of the received digital stream through the decoder for presentation thereof on the display upon resumption of play, the means for sending a recorded version accounting for time base discontinuities in the stream.
