This invention takes advantage of the potential for a group of data channels, especially if they are carrying a related form of information such as human telephone conversations, to be compressed for transmission as a group to a greater degree than if the channels were compressed individually. A focus of the system and method of this invention is the organization of data from multiple channels, before the data are compressed for transmission, thereby taking advantage of redundant, extraneous or unnecessary information in common among the data. In a preferred embodiment, the invention organizes and processes human speech data from multiple voice-grade telephone channels into a highly compressed representation for transport by a packet switched network, and receives and processes those highly compressed representations to reconstruct, exactly or approximately, the human speech data. This embodiment thus provides for efficient bulk transport of multiple voice-grade telephone channels through a packet switched network. More generally, the present invention provides a system and method for processing data from multiple channels into alternate representations in order to facilitate efficient transmission. The invention more generally also provides a system and method for processing such alternate representations in order to reconstruct, exactly or approximately, data for transmission on multiple channels.
