Reception apparatus and data processing method

A data processing method for a reception apparatus, the data processing method comprising the steps of:

• by the reception apparatus,
• receiving a digital broadcast signal of an IP transmission method including time information and a stream of content, the time information including a seconds field and a nanoseconds field;
• generating a processing clock synchronized with the time information on the basis of the time information included in the digital broadcast signal;
• and
• processing the stream included in the digital broadcast signal on the basis of the processing clock.

A reception apparatus comprising:

• a reception unit that receives a digital broadcast signal of an IP transmission method including time information and a stream of content;
• a demodulation unit that demodulates a frame of a physical layer in a protocol stack of the IP transmission method;
• a clock generation unit that generates a processing clock on the basis of a system clock generated from a physical-layer clock corresponding to a frame period of the frame, the processing clock based on the time information obtained from the frame;
• and
• a processing unit that processes the stream included in the digital broadcast signal on the basis of the processing clock,
• wherein the physical-layer clock and the system clock are synchronized in a transmission apparatus that transmits the digital broadcast signal.
