Abstract: A multimedia data stream is partitioned into two or more parts based on importance, e.g., a first part might represent more significant bits in groups of bits representing pixel colors in a video frame, while a second part might represent the less significant bits in the groups. The more important part of the stream is amplified more than the less important part of the stream.

Abstract: A method of adding hangover frames to a plurality of frames encoded by a vocoder, the method comprising: detecting that a predefined number of successive frames has been encoded at a first rate; determining that a next successive frame should be encoded at a second rate that is less than the first rate; and selecting a number of successive hangover frames beginning with the next successive frame to encode at the first rate, the numbering dependent upon an estimate of a background noise level.

Abstract: An apparatus and method for performing speech signal compression, by variabl e rate coding of frames of digitized speech samples (10). The level of speech activity for each frame of digitized speec h samples is determined and an output data packet rate is selected from a set of rates based upon the determined level of frame speech activity. A lowest rate of the set of rates corresponds to a detected minimum level of speech activity, such as backgrou nd noise or pauses in speech, while a highest rate corresponds to a detected maximum level of speech activity, such as active vocalization. Each frame is then coded according to a predetermined coding format for the selected rate wherein each rate has a corresponding number of bits representative of the coded frame. A data packet is provided for each coded frame with each output data packet of a bit rate corresponding to the selected rate.
