Information processing apparatus, method, and program

An information processing method for reproducing by an information receiving apparatus a second media content in synchronization with reproduction of a first media content, the first media content comprising audio content, the information processing method comprising:

• extracting an audio-derived feature from an audio signal generated via reproduction of the audio content by a second information receiving apparatus;
• obtaining, from an information providing apparatus different from the second information receiving apparatus, the second media content together with a synchronization feature, the synchronization feature being extracted from the audio content of the first media content prior to being transmitted by the information providing apparatus;
• comparing the audio-derived feature with the synchronization feature;
• generating, based on results of the comparing, synchronization information;
• and
• reproducing, using the generated synchronization information and by the information receiving apparatus, the second media content in synchronization with reproduction of the first media content by the second information receiving apparatus.

At least one non-transitory computer readable storage medium storing processor-executable instructions that, when executed by at least one computer, causes the at least one computer to perform an information processing method for reproducing by an information receiving apparatus a second media content in synchronization with reproduction of a first media content, the first media content comprising audio content, the information processing method comprising:

• extracting an audio-derived feature from an audio signal generated via reproduction of the audio content by a second information receiving apparatus;
• obtaining, from an information providing apparatus different from the second information receiving apparatus, the second media content together with a synchronization feature, the synchronization feature being extracted from the audio content prior to the first media content being transmitted by the information providing apparatus;
• comparing the audio-derived feature with the synchronization feature;
• generating, based on results of the comparing, synchronization information;
• and
• reproducing using the generated synchronization information and by the information receiving apparatus the second media content in synchronization with reproduction of the first media content by the second information receiving apparatus.

An information providing apparatus for transmitting a first media content and a second media content to one or more other devices, the first media content comprising audio content, the information providing apparatus comprising:

• circuitry configured to:
• extract a synchronization feature from the audio content of the first media content prior to transmission of the first media content to the one or more other devices;
• associate, in synchronization with the first media content, the synchronization feature with the second media content that has a time-synchronized relationship with the first media content;
• transmit the first media content to a first receiving device;
• and
• transmit the second media content together with the synchronization feature to a second receiving device different from the first receiving device.

An information processing method for transmitting by an information providing apparatus a first media content and a second media content to one or more other devices, the first content comprising audio content, the method comprising:

• extracting a synchronization feature from the audio content of the first media content prior to transmission of the first media content to the one or more other devices;
• associating, in synchronization with the first media content, the synchronization feature with second media content that has a time-synchronized relationship with the first media content;
• transmitting the first media content to a first receiving device;
• and
• transmitting the second media content together with the synchronization feature to a second receiving device different from the first receiving device.
