Abstract

A media stream system ( 140 ) processes plural media streams ( 148 ), e.g., speech streams or speech channels. The system comprises plural processors ( 146 ), each of which execute one or more plural types of media stream processing functions ( 147 ). A switch function ( 144 ) routes packets of the plural media streams to a sequence of the plural processors whereby the plural types of media stream processing functions are sequentially performed relative to the packets. A packet size for the packets is chosen to minimize overhead load on at least one of the plural processors without causing undue delay for a packet awaiting processing by the at least one of the plural processors. In an example non-limiting implementation, the packet size for a packet of media information is chosen to be 160 octets, consecutive packets of a same media stream being separated by a packet repetition interval which is 20 milliseconds.
