Abstract

A receiving device including a receiver and circuitry is provided. The receiver is configured to receive a digital broadcast signal transmitted using an Internet Protocol (IP) transmission method. The digital broadcast signal includes Layered Coding Transport (LCT) packets. The circuitry is configured to extract one of the LCT packets based on filtering information arranged in a header of the one of the LCT packets transmitted in a first layer that is higher than an IP layer of a protocol of the IP transmission method in the digital broadcast signal, and process first signaling data contained in the one of the LCT packets. The LCT packets are transmitted using a session of the first layer. The filtering information includes compression information indicating compression/no-compression of the first signaling data, and type information indicating a type of the first signaling data.
