摘要：
A transmission side apparatus selectively inserts video stream data and MPEG data into a video storage area to store video stream data in a frame structure of an SDI system and generates SDI data of which the identification ID indicating a type of data included therein by an SDI data insertion processing device and transmits the SDI data to a coaxial cable from a transmission interface device. A reception side apparatus receives the SDI data transmitted via the coaxial cable by a reception interface device, extracts data to be transmitted from a video storage area of received SDI data and determines whether the data to be transmitted is the video stream data or the MPEG data by an SDI data extraction processing device to output it. Therefore, a high-speed MPEG data transmission assuring frame/field accuracy becomes possible by using an existing technology and device.
