Abstract:
A method for generating a multiplexed sequence, the method comprising the steps of:receiving at least one media unit sequence; for each media unit sequence performing the steps of: calculating a sequence time threshold, in response to: (a) timing information embedded within the media unit sequence, (b) an estimated allocated bit rate of the media unit sequence, and (c) aggregate size of at least some media units belonging to the media unit sequence; determining a target size of a media unit group in response to the corresponding sequence time threshold, the media unit group comprising at least some of the media units of the sequence; decreasing the size of the media unit group by modifying at least one media unit of the media unit group, to generate at least one corresponding modified media unit, if the size of the media unit group is greater than the target size; and appending at least one corresponding modified media unit in place of the media units to the multiplexed sequence, if the at least one corresponding modified media unit was generated during the step of decreasing the size of the media unit group.
