Method and system to improve the transport of compressed video data in real time

A system to process a variable bit rate (VBR) representation of an image sequence, the VBR representation comprising a plurality of packets of blocks of information, the system comprising:

• a processor to segment the VBR representation based on a plurality of time intervals, and for each of at least two of the time intervals:
• to determine which of the packets, denoted by Pp, in the VBR representation within a presently-considered time interval has a number of blocks of information per unit time greater than a baseline value;
• to determine which of the packets, denoted by Pn, in the VBR representation within the presently-considered time interval has a number of blocks of information per unit time less than the baseline value;
• and
• to create a second representation of the image sequence in which some blocks of information Bp are removed from at least one Pp packet and interlaced with blocks of information in at least one Pn packet to produce reformatted packets having a reduced variation in a number of blocks of information per unit time.

A computer-readable medium having computer program code to direct a processor to process a variable bit rate (VBR) representation of an image sequence, the VBR representation comprising a plurality of packets of blocks of information, the computer program code directing the processor to:

• segment the VBR representation based on a plurality of time intervals;
• and
• for each of at least two of the time intervals:
• determine which of the packets, denoted by Pp, in the VBR representation within a presently-considered time interval has a number of blocks of information per unit time greater than a baseline value;
• determine which of the packets, denoted by Pn, in the VBR representation within the presently-considered time interval has a number of blocks of information per unit time less than the baseline value;
• and
• create a second representation of the image sequence in which some blocks of information Bp are removed from at least one Pp packet and interlaced with blocks of information in at least one Pn packet to produce reformatted packets having a reduced variation in a number of blocks of information per unit time.
