Receiving device, receiving method, transmitting device, and transmitting method

A receiving method of a receiving device, the method comprising the steps of, by the receiving device:

• receiving, by receiver circuitry of the receiving device, an audio/video content stream;
• decoding audio/video content included in the audio/video content stream for display to a user;
• extracting fingerprint information or watermark information from the audio/video content included in the audio/video content stream,
• acquiring, from a server via broadband communication, a single data structure including location information of a component associated with the audio/video content stream and time information indicating a reference time for performing display control of the component, the location information and the time information being acquired based on the fingerprint information or the watermark information;
• acquiring component information, including the component associated with the audio/video content stream, from a location indicated by the location information in the single data structure including the reference time for performing the display control of the component;
• and
• controlling displaying of the component according to the time information in the single data structure including the location information from which the component was acquired.

A transmitting device comprising:

• processing circuitry configured to transmit an audio/video content stream including fingerprint information or watermark information, wherein
• the fingerprint information or the watermark information is extracted from an audio/video content, included in the audio/video content stream, in a receiving device,
• a single data structure including location information of a component associated with the audio/video content stream and time information indicating a reference time for performing display control of the component are acquired from a server via broadband communication, by the receiving device, the location information and the time information being acquired based on the fingerprint information or the watermark information, component information, including the component associated with the audio/video content stream, is acquired, by the receiving device, from a location indicated by the location information in the single data structure including the reference time for performing the display control of the component, and
• displaying of the component is controlled, in the receiving device, according to the time information in the single data structure including the location information from which the component was acquired.

A transmitting method of a transmitting device, the method comprising:

• transmitting, by processing circuitry of the transmitting device, an audio/video content stream including fingerprint information or watermark information, wherein
• the fingerprint information or the watermark information is extracted from an audio/video content, included in the audio/video content stream, in a receiving device,
• a single data structure including location information of a component associated with the audio/video content stream and time information indicating a reference time for performing display control of the component are acquired from a server via broadband communication, by the receiving device, the location information and the time information being acquired based on the fingerprint information or the watermark information,
• component information, including the component associated with the audio/video content stream, is acquired, by the receiving device, from a location indicated by the location information in the single data structure including the reference time for performing the display control of the component, and
• displaying of the component is controlled, in the receiving device, according to the time information in the single data structure including the location information from which the component was acquired.
