(EN) SYSTEM AND METHOD FOR PROCESSING DATA FROM AND FOR MULTIPLE CHANNELS
(FR) SYSTEME ET PROCEDE DE TRAITEMENT DE DONNEES ECHANGEES SUR PLUSIEURS CANAUX
Abstract
(EN) 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.
(FR) Cette invention tire parti de la capacité potentielle d'un groupe de canaux donnés, surtout s'ils transportent des formes d'informations apparentées telles que des conversations téléphoniques, à être comprimés en groupe en vue de leur transmission, avec un rapport de compression plus élevé que s'ils étaient comprimés individuellement. Le système et le procédé se focalisent sur l'organisation des données des différents canaux, avant leur compression en vue de la transmission, en tirant parti de la présence des information redondantes, étrangères ou inutiles communes aux données. Dans une exécution préférée, l'invention organise et traite les données de conversations transitant sur des canaux téléphoniques de différentes qualités de voix pour en faire une représentation fortement comprimée transmissible sur un réseau à commutation de paquets, et reçoit et traite ces mêmes représentations pour reconstituer exactement ou approximativement les données des conversations d'origine. Cette exécution peut assurer un transfert massif efficace de canaux téléphoniques de différentes qualités de voix sur un réseau à commutation de paquets. D'une manière plus générale, l'invention porte sur un système et un procédé de traitement de données de plusieurs canaux en représentations alternées pour en faciliter la transmission efficace, et pour reconstituer exactement ou approximativement des données en vue de leur transmission sur plusieurs canaux.
