A data processing system buffers temporarily a portion of a plurality of compressed data streams. Each portion comprises one or more units of an encoded media signal. A switch provides selective connectivity between the buffer and a plurality of processors analyzing the one or more units of the encoded media signal in the buffer and generating statistical data about the encoded media signal. One or many transcoders are configured to decode a second portion of the compressed data streams, which includes units ordered ahead of the one or more units in the buffer, and then encode the second portion of the compressed data streams based on the statistical data. A controller receives the statistical data from the processors and directs the encoding of the second portion of the compressed data streams.
L'invention concerne un système de traitement des données comprenant une mémoire tampon permettant de stocker temporairement une partie d'une pluralité de flux de données compressé ainsi qu'un commutateur. Chaque partie du flux compressé comprend une ou plusieurs unités d'un signal multimédia codé. Le commutateur assure une connectivité sélective entre la mémoire tampon et une pluralité de processeurs. La pluralité de processeurs peut être configurée pour analyser l'unité ou les unités du signal multimédia codé stocké dans la mémoire tampon afin de générer des données statistiques relatives au signal multimédia codé.
