1. A method comprising:
- providing a variable bit rate (VBR) representation of an image sequence, the VBR representation comprising a plurality of blocks of information;
determining a first plurality of blocks of information per unit time that is greater than a second plurality of blocks of information per unit time; and
creating a second representation of the image sequence in which some of the first plurality of blocks of information are interlaced with blocks of information of the second plurality of blocks of information to reduce a variation in a number of blocks of information.

Abstract
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.
