Receiving device, reception method, transmitting device, and transmission method

A receiving device comprising:

• a receiver configured to receive a digital broadcast signal transmitted using an Internet Protocol (IP) transmission method, the digital broadcast signal including Layered Coding Transport (LCT) packets;
• and
• circuitry 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 stored in the one of the LCT packets, wherein
• the LCT packets are transmitted using a session of the first layer,
• the filtering information includes compression information representing compression/no-compression of the first signaling data, filter information representing a filtering condition of the first signaling data, and version information representing a version of the first signaling data, and
• the filter information indicates which of a plurality of types of the first signaling data is contained in the first signaling data.
