Abstract
A method for regulating bandwidth usage in an output data stream transmitted on an analog channel from a cable head end. The output data stream comprises a plurality of input information content signals. For each input information content signal, a series of images are captured, compressed and formed into an input digital data stream. The bandwidth of each input digital data stream is regulated by associating the stream with a current bit allocation total. During each frame time: a bit allocation increment is added to the current bit allocation total for each input digital data stream. When a data packet to be transmitted for an input digital data stream is received by the multiplexer, the data packet is stored. When the number of bits in the stored data packet is not more than the current bit allocation total for the input digital data stream, the multiplexer forwards the stored data packet for transmission in the output data stream on the analog channel and decrements the current bit allocation total for the given input digital data stream by the number of bits in the stored data packet. In this way, no individual input channel takes more than its share of the bandwidth on the output stream on the analog channel.
