A novel system architecture and an automatic monitoring method for remote production

Remote production is an emerging concept concerning the outside-broadcasting workflow enabled by Internet Protocol (IP)-based production systems, and it is expected to be much more efficient than the conventional workflow. However, long-distance transmission of uncompressed video signals and time synchronization of distributed IP-video devices are challenging. A system architecture for remote production using optical transponders (capable of long-distance and large-capacity optical communication) is proposed. A field experiment confirmed that uncompressed video signals can be transmitted successfully by this architecture. The status monitoring of uncompressed video transmission in remote production is also challenging. To address the challenge, a method for automatically monitoring the status of IP-video devices is also proposed. The monitoring system was implemented by using whitebox transponders, and it was confirmed that the system can automatically register IP-video devices, generate an IP-video flow model, and detect traffic anomalies.
