Title:
TRANSMISSION SYSTEM, TRANSMISSION METHOD, INSERTER, AND DATA CONSTRUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/153486
Kind Code:
A1
Abstract:
A transmission system S according to an embodiment of the present invention comprises an inserter (30) and construction devices (50, 70). The inserter (30) divides a first transmission main signal and generates a plurality of second transmission main signals, then multiplexes the second transmission main signals and configuration information of the first transmission main signal into a first broadcast transport stream (TS) and sends a second broadcast TS. The construction devices (50, 70) receive the second broadcast TS, extract the plurality of second transmission main signals and the configuration information from the second broadcast TS, and construct the first transmission main signal by using the configuration information and the plurality of second transmission main signals.
