Abstract
A method and apparatus for classifying video flows to minimize switching time at a user terminal is described. One aspect of the invention relates to classifying video for distribution. A plurality of classes associated with a respective plurality of network jitter measures is established. A jitter profile for a plurality of video flows is defined by associating each video flow of the plurality of video flows with one of the plurality of classes based on an estimated jitter measure of the video flow. The jitter profile is distributed towards at least one user terminal from a distribution facility. The user terminal may use the jitter profile to set the fill level of its jitter buffer dynamically according to the particular video flow being decoded.
