1. A method performed by a digital home communication terminal (DHCT), comprising:

  • receiving a video stream in a transport stream from a headend by the DHCT, the video stream comprising a first message comprising first information from a splicer; and

    controlling an overlap transition period via the first information from the splicer;

    wherein controlling the overlap transition period includes;

    controlling, via the first information, output of decoded picture buffer (“

    DPB”

    ) pictures at the splice point of non-seamless concatenated bitstreams; and

    controlling, via the first information, DPB space usage for the overlap transition period lasting a number of picture output times defined in the first information.
