In a method for admitting a new data file into a channel, a request for admission of the new data file into the channel is received. It is determined as to whether at least a minimum number of bits of at least one current data file has been transferred to the receiver. The rate at which the at least one current data file is transferred is reduced below a minimum constant bit rate in response to a determination that at least a minimum number of bits of the at least one current data file has been transferred to the receiver and the new data file is admitted into the channel.

Admitting a data file into a channel

A method for controlling flow of a video content signal through a communications system, such as a video on-demand system creates a unique message for each individual video content signal and attaches the unique message to each individual video content signal prior to transmitting the video content signal through the communications system to a designed end user system. In one exemplary embodiment, the unique message comprises an in-band signaling message, such as a message inserted in a program map table in an MPEG packetized signal.

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.
