ABSTRACT:
In a video server a transport stream is generated. The transport stream is to be transported over a circuit of a network signalling at a constant bit rate. During generation, timed program content is encoded as a variable bit rate stream. The variable bit rate stream is transported over a constant bit rate circuit of a network. While transporting the variable bit rate stream, an accumulated difference between the number of bits transported in the variable bit rate stream and the number of bits required for the constant bit rate circuit is measured periodically. In response to the measured difference, a secondary untimed content is supplied to the constant bit rate circuit at a rate which minimizes the accumulated difference, and where the secondary content is evenly distributed over the transport stream.
