TRANSMISSION DEVICE FOR DEALING WITH ASYNCHRONOUS COMMUNICATION NETWORK, TRANSMITTER AND RECEIVER

摘要

PROBLEM TO BE SOLVED: To allow a transmitter and a receiver to mutually transmit video signals stipulated by various standards through an ATM network. SOLUTION: A line memory number storage device 13 stores image data of a prescribed of number lines. An EAV/SAV detector 10 detects an EAV/SAV signal and outputs an EAV/SAV detection signal and a time stamp provision device 20 measures the elapsed time and outputs elapsed time information. An SDU generator 21 adds the elapsed time information to synchronous information generated. A data separator 11 separates image data form auxiliary data. A rearrangement processing unit 14 segments entire sets of line data equivalent to a prescribed line number form the image data and rearranges them in accordance with prescribed rules. An error correction code adder 15 adds an error correction code to the auxiliary data.
