IN-PLANT SYSTEM DIGITAL VIDEO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To directly exchange a video frame at it is by using address information and to improve communication efficiency with a simple configuration by attaching the address information to the space area of a digital video frame. SOLUTION: Address information storage devices 102 store address information showing a sending end switch connecting device, following a tag showing that the address information is included in the space area of a digital video frame. When switch connecting devices 103 output to a switch 104 according to the address information, the switch 104 recognizes the tag, reads the address information and transfers the video frame to a switch connecting device 105 of a transmission destination. The video frame is sent to an address information releasing device 106 and is reproduced by a video input-output device 107 after the tag and the address information are eliminated. The digital video frame can be transferred between video input and output without adding a header and simplification is carried out without needing packet assembly or frame reproduction.
