Method and system to improve the transport of compressed video data

摘要

A method comprises determining a plurality of time intervals Tp and Tn within a variable bit rate (VBR) representation of an image sequence. The time intervals Tp are those in which a number of blocks of information per unit time is greater than a baseline value. The time intervals Tn are those in which a number of blocks of information per unit time is less than the baseline value. A second representation of the image sequence is created in which some blocks of information Bp are removed from the time intervals Tp and interlaced with blocks of information Bn in the time intervals Tn to reduce a variation in a number of blocks of information per unit time between the time intervals Tp and Tn.

1. A method comprising:
determining a first plurality of time intervals within a variable bit rate representation of an image sequence in which information blocks per unit time are greater than in a second plurality of information blocks per unit time; generating interlaced information blocks by interlacing information blocks from the first plurality and information blocks from the second plurality to reduce bit rate variation in the stream to be sent; populating a header in the interlaced information blocks with data identifying information blocks from the first plurality and information blocks from the second plurality; and streaming the interlaced information blocks via a communication network.
