Vorrichtung zur Verarbeitung und Leiten von Daten

摘要

A data emitting unit is designed to transmit to a routing unit and identifier. The routing unit includes a programmable communication table which allows it to determine the data processing receiver from the identifier. The system includes a variable length de-encrypting unit VLD (40). A inverse zigzag sweep and inverted quantification ISIQ unit (43). A discrete cosine transformation unit (44) zigzag quantification and sweep QS unit (48) and variable length encryption unit (47). <??>Data processing and routing unit includes a data bus (10); a routing unit (15) which manages communications on the data bus; a processor unit designed to transmit and receive data, and; a local memory (16). The receiver provides a signal for the routing unit. The routing unit is designed to authorize data emission by the transmitter to the local memory (16) or to the receiver as a function of the value of the available signal.
