Abstract
Variable-rate encoding of a signal by processing the signal to determine the data rate demand over a time period for multiple values of an encoding parameter, such as a quantization parameter which affects the encoded data rate, and selecting a value for the encoding parameter with which to encode a segment of the time period. Determining the data rate demands of a set of image sequences and selecting a subset of the sequences based on the data rate demands, for example, to satisfy a storage volume constraint, and then encoding each of the selected subset of sequences for transmission or storage.
