Data processing apparatus and data processing method

A data processing method, comprising:

• receiving, by first processing circuitry of a data processing apparatus via an antenna, a digital broadcast signal;
• performing a demodulation process on the digital broadcast signal by the first processing circuitry to obtain reception data;
• generating, by the first processing circuitry, notification data to be transmitted to second processing circuitry of the data processing apparatus, the notification data indicating errors or successes of various stages of the demodulation process performed by the first processing circuitry or a setting of the first processing circuitry for performing the demodulation process;
• generating, by the first processing circuitry, a data packet that encapsulates the reception data and the notification data;
• and
• outputting the generated data packet that encapsulates the reception data and the notification data to the second processing circuitry via an interface for further processing of the reception data;
• wherein
• the first processing circuitry and the second processing circuitry are connected by the interface which is a single interface therebetween,
• the digital broadcast signal supports an Internet Protocol (IP) transport scheme using an IP packet including a User Datagram Protocol (UDP) packet, and
• the data packet is generated by adding the notification data to an additional header of a first transport packet for transporting the IP packet, to signaling included in the first transport packet, to a header of the signaling, to an additional header of a second transport packet for transporting the first transport packet, to an extension area outside the first transport packet, or to an extension area outside the second transport packet.

A data processing apparatus comprising:

• first processing circuitry configured to:
• receive a digital broadcast signal via an antenna;
• perform a demodulation process on the digital broadcast signal to obtain reception data;
• generate notification data to be transmitted to second processing circuitry, the notification data indicating errors or successes of various stages of the demodulation process performed by the first processing circuitry or a setting of the first processing circuitry for performing the demodulation process;
• generate a data packet that encapsulates the reception data and the notification data;
• and
• output the generated data packet that encapsulates the reception data and the notification data to the second processing circuitry via an interface for further processing of the reception data,
• wherein
• the data processing apparatus that includes the first processing circuitry corresponds to an information processing apparatus that delivers content acquired from the digital broadcast signal,
• the second processing circuitry corresponds to a terminal apparatus that reproduces the content delivered from the information processing apparatus,
• the information processing apparatus and the terminal apparatus are configured as separate apparatuses and connected via a network as the interface,
• the digital broadcast signal supports an Internet Protocol (IP) transport scheme using an IP packet including a User Datagram Protocol (UDP) packet, and
• the first processing circuitry is further configured to
• convert a packet holding the reception data and a packet holding the notification data into an IP packet as the generated data packet, and
• send the IP packet to the second processing circuitry via the network.
