Data processing device, data processing method, and program

A data processing method comprising the steps of:

• extracting a character string targeted for a search from subtitle data of content data including image data, voice data, and the subtitle data,
• searching the voice data for data of a voice uttering the character string, acquiring timing information indicating time when the character string is uttered, the timing information being included in the image data,
• generating subtitle timing information including identification information provided to identify the subtitle data including the character string and the timing information, where the identification information and the timing information are associated with each other, so that the subtitle timing information is acquired, and
• synchronizing the subtitle data and image data of time indicated by timing information associated with identification information of the subtitle data, and outputting the subtitle data and the image data based on the subtitle timing information through a data processing device.

A data processing device comprising:

• an output control unit configured to extract a character string targeted for a search from subtitle data of content data including image data, voice data, and the subtitle data,
• search the voice data for data of a voice uttering the character string, acquire timing information indicating time when the character string is uttered, the timing information being included in the image data,
• generate subtitle timing information including identification information provided to identify the subtitle data including the character string and the timing information, where the identification information and the timing information are associated with each other, so that the subtitle timing information is acquired, and
• synchronize the subtitle data and image data of time indicated by timing information associated with identification information of the subtitle data, and output the subtitle data and the image data based on the subtitle timing information.
