1. A method comprising:
- creating a second representation of a variable bit rate representation of an image sequence comprising a plurality of blocks of information in which some of a first plurality of blocks of information per unit time are interlaced with blocks of information of a second plurality of blocks of information per unit time to reduce a variation in a number of blocks of information per unit time; and
populating a header in the second representation with data indicating which blocks of information of the first plurality of blocks of information are interlaced with blocks of information of the second plurality 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.

-
creating a second representation of a variable bit rate representation of an image sequence comprising a plurality of blocks of information in which some of a first plurality of blocks of information per unit time are interlaced with blocks of information of a second plurality of blocks of information per unit time to reduce a variation in a number of blocks of information per unit time; determining the first plurality of blocks of information per unit time is greater than the second plurality of blocks of information per unit time; and populating a header in the second representation with data indicating which blocks of information of the first plurality of blocks of information are interlaced with blocks of information of the second plurality of blocks of information. - View Dependent Claims (9, 10, 11, 12)

13. A system comprising:
-
a processor configured to create a second representation of a variable bit rate representation of an image sequence comprising a plurality of blocks of information in which some of a first plurality of blocks of information per unit time are interlaced with blocks of information of a second plurality of blocks of information per unit time to reduce a variation in a number of blocks of information per unit time; wherein the number of blocks of information per unit time in the second representation is about equal to a baseline value; and further wherein the processor is further configured to populate a header in the second representation with data indicating which blocks of information of the first plurality of blocks of information are interlaced with blocks of information of the second plurality of blocks of information. - View Dependent Claims (14, 15)
