Abstract:
1. A method for splicing digitally encoded data streams, including an old data stream and a new data stream, comprising: (a) without the use of a clock reference signal, modifying a current timing reference of the new data stream to correspond with a splice-out point of the old data stream and a splice-in point of the new data stream, thereby forming a modified new data stream timing reference, wherein said modified new data stream timing reference further corresponds with a timing gap between a first decoding time for decoding a last frame of the old data stream and a second decoding time for decoding a first frame of the new data stream; and (b) aligning a portion of the new data stream with a portion of the old data stream according to said modified new data stream timing reference, such that a transition from the old data stream to the new data stream, during playback, will be substantially imperceptible.
