DATA TRANSMITTING DEVICE, DATA TRANSMITTING METHOD AND VIDEO CAMERA SYSTEM USING THEM

摘要

A data transmitting device and a camera system which transmit serial data between, e.g., a CHU(1) and a CCU(2) by adding the serial data to the horizontal blanking section of the video data. On the transmitting side, resampled data are obtained by sampling the serial data using a clock of a frequency higher than the transmission rate and generating data for multiplexing by selecting a fixed number of data from the resampled data obtained during every horizontal period, and then, the multiplexing data are transmitted by adding the multiplexing data on the horizontal blanking section of the video data. On the receiving side, the multiplexing data are separated from the received video data and decoded, definition data constituting the original serial data are extracted, and the serial data are reproduced.
