Abstract:
1. A method of reproducing at least two digital video sequences each comprising a plurality of coded pictures, the method comprising: multiplexing a first digital video sequence with a second digital video sequence, wherein pictures of the second digital video sequence are included in advance in a video stream and are associated with timing information such that a receiver will not decode and reproduce the pictures of the second digital video sequence; composing the at least two digital video sequences into the video stream in correspondence with a result of the multiplexing; subsequently including a sequence of dummy timing pictures into the video stream; wherein the dummy timing pictures are inter-predicted from at least one picture of the second video sequence coded in advance in the video stream, wherein the dummy timing pictures are coded by omitting any prediction error data; and wherein decoding the dummy timing pictures results in copies of decoded pictures corresponding to the at least one picture of the second sequence being included in the video stream in advance.
