ATM ADAPTATION LAYER RX FOR FIXED BIT RATE IMAGE SERVICE

摘要

an input/output signal generator driven by a system clock supplied from a network; a video codec connector for impendence-matching an input/output signal from the input/output signal generator and a video signal upon connection of a video codec; a convergence part layer generator for generating a CS-PDU payload by processing a convergence part layer which receives the input/output signal from the input/output signal generator and data and a clock signal from the video codec connector; an SAR part layer processor for receiving an output signal from the convergence part layer generator to generate an SAR header and for connecting the header to the CS-PDU payload to transmit the connected SAR-PDU payload to an asynchronous transfer mode layer; a clock information generator for receiving the input/output signal from the input/output signal generator and the clock signal from the video codec connector and for generating acknowledging information being synchronous to a network driving clock and required for clock restoration; and a managing/state signal processor for communicating a managing/state signal in a transmitting part to an external controller.
