Method and System to Improve the Transport of Compressed Video Data
First Claim
1. A method of reconstructing an image sequence originally encoded in a variable bit rate (VBR) representation, the VBR representation comprising a first plurality of blocks of information and a second plurality of blocks of information, the first plurality of blocks of information comprising more blocks of information than the second plurality of blocks of information, the method comprising:
- receiving a second representation of the image sequence in which some 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 to reduce a variation in a number of blocks of information per unit time in the image sequence; and
reconstructing frames of the image sequence concurrently with said receiving, said reconstructing comprising;
during a period of time when the received stream comprises blocks of information of the first plurality of blocks of information only, reconstructing frames of the image sequence based on blocks of information of the first plurality of blocks of information stored in a buffer and blocks of information received about in real time.

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.
