Sendung und Empfang von Daten

摘要

A data transmission system (1) can transmit and receive signals of a serial data interface (SDI) system and of a serial digital data interface (SDDI) system mixed on the same transmission path (SDI/SDDI). A serial to parallel conversion circuit (200) receives a transmission signal and converts it to a reception signal of a 10-bit parallel format. A packet classification data detection circuit (202) detects the transmission packet from the reception signal and detects the content of positions of separation codes SAV and EAV of the transmission packet. A FIFO (204) performs buffering so that the beginning of the transmission packet will not be cut off. A selector circuit (206) separates the SDI data and the SDDI data under the control of a control circuit (210) in accordance with the contents of the SAV and EAV of the transmission packet and outputs the separated data. <IMAGE>
