[Paper] Monitoring Tool for IP-based Program-production Systems in Conjunction with NMOS Control Information

抄録

For Internet Protocol (IP)-based program-production systems, a flexible network can be deployed depending on the configuration. However, it is difficult for broadcast engineers to respond to problems because of this flexibility. We introduce an IP-based program-production-system monitoring tool for broadcast engineers. It visualizes transmission routes, throughput, packet loss, and other transmission states of an arbitrary signal from the results of analyzing signals on the network link and running status of network switches. It automatically verifies the transmission status of IP flows in conjunction with Networked Media Open Specifications control information. When verification fails, information related to the problems is presented to the broadcast engineers so that they can troubleshoot the IP-based program-production systems.
