Patent ID: 7054371

Claim:
A system for real time transmission of variable bit rate MPEG video traffic with consistent quality, comprising: a video encoder for encoding video data; an encoder buffer for storing encoded video data; an encoder rate controller for estimating a number of bits quantized from a target quantization parameter during a frame of said video data corresponding to discrete cosine transform (DCT) coefficients of said frame, and for providing quantization parameters based on slice level to said encoder; a channel rate controller for dynamically generating parameters for smoothing and bandwidth renegotiation corresponding to said number of bits generated from said encoder rate controller, wherein smoothing includes reducing a peak transmission rate to a sustainable transmission rate and smoothing a transmission rate to said sustainable transmission rate; a network for generating negotiated parameters corresponding to said parameters generated from said channel rate controller; and a counter for transmitting said video data stored in said encoder buffer through said network at a smoothed transmission rate, in response to said negotiated parameters.
