SI transmission device, SI transmission system, SI transmission method, and operation method of SI transmission system

摘要

PROBLEM TO BE SOLVED: To realize stable provision of SI information to a reproduction device in a configuration in which an SI information transmission device can be switched. SOLUTION: This is an SI transmission device that transmits SI information included in a broadcast wave, and receives a frame in which the SI information is stored, and the SI information is divided and stored from the received frame. A TS packet processing unit that generates and outputs a TS packet containing a count value, and an IP packet that stores one or more of the TS packets received from the TS packet processing unit are generated and transmitted. The TS packet processing unit can operate as an active system and an operation as a standby system, and operates between the frame and the count value without discontinuity with the other SI transmission device. Performs switching processing to switch between the system and the standby system. [Selection diagram] Fig. 2
