Transmission device, transmission method, reception device, and reception method

A transmission method in which

• a transmission device that
• transmits a first broadcast signal via a first transmission antenna, the first broadcast signal includes a first transmission control signal compatible with a first system and a signal of a first content compatible with the first system and a signal of a second content compatible with a second system, and
• transmits a second broadcast signal via a second transmission antenna, the second broadcast signal includes a second transmission control signal compatible with the second system and the signal of the second content.

A reception device comprising

• a reception unit that receives a first broadcast signal transmitted from a transmission device via a first reception antenna,
• the transmission device including a transmission unit that includes a first transmission control signal compatible with a first system in the first broadcast signal including a signal of a first content compatible with the first system and a signal of a second content compatible with a second system and transmits the first broadcast signal via a first transmission antenna, and includes a second transmission control signal compatible with the second system in a second broadcast signal including a signal of the second content and transmits the second broadcast signal via a second transmission antenna.

A reception method comprising:

• receiving, by a reception device, a broadcast signal transmitted from a transmission device receives a first broadcast signal transmitted from the transmission device via a first reception antenna,
• the transmission device including a transmission unit that includes a first transmission control signal compatible with a first system in the first broadcast signal including a signal of a first content compatible with the first system and a signal of a second content compatible with a second system and transmits the first broadcast signal via a first transmission antenna, and includes a second transmission control signal compatible with the second system in a second broadcast signal including the signal of the second content and transmits the second broadcast signal via a second transmission antenna, and
• performing, by the reception device, processing including demodulation and decoding of the signal of the first content included in the first broadcast signal received, on a basis of the first transmission control signal included in the first broadcast signal received.

A reception method comprising:

• receiving, by a reception device, a broadcast signal transmitted from a transmission device receives a first broadcast signal transmitted from the transmission device via a first reception antenna and receives a second broadcast signal via a second reception antenna,
• the transmission device including a transmission unit that includes a first transmission control signal compatible with a first system in the first broadcast signal including a signal of a first content compatible with the first system and a signal of a second content compatible with a second system and transmits the first broadcast signal via a first transmission antenna, and includes a second transmission control signal compatible with the second system in the second broadcast signal including the signal of the second content and transmits the second broadcast signal via a second transmission antenna, and
• performing, by the reception device, processing including demodulation and decoding of the signal of the second content included in the first broadcast signal and the second broadcast signal received, on a basis of the second transmission control signal included in the second broadcast signal received.
