Metadata preparing device, preparing method therefor and retrieving device
First Claim
1. A metadata production device, comprising:
- a content reproduction portion that reproduces and outputs content;
an voice input portion;
a voice recognition portion that recognizes voice signals that are input from the voice input portion;
a metadata generation portion that converts information recognized by the voice recognition portion into metadata;
an identification information attaching portion that obtains identification information for identifying positions within the content from the content and attaches the identification information to the metadata; and
a dictionary that is limited in accordance with the content;
whereby the generated metadata is associated with positions in the content; and
the recognition is performed in association with the dictionary, when recognizing the voice signals input from the voice input portion with the voice recognition portion.

18. A metadata search device, comprising:
-
a content database that reproduces and outputs content;
an voice input portion that converts voice signals of entered keywords into data with a clock signal that is synchronized with a synchronization signal of the reproduced content;
a voice recognition portion that recognizes the keywords from the voice signal data that has been converted into data by the voice input portion;
a file processing portion that produces a metadata file by combining the keywords that are output from the voice recognition portion with time codes that indicate a time position of an image signal that is included in the content;
a content information file processing portion that generates a control file controlling a relation between the metadata file and recording positions of the content file;
a recording portion that records the content file, the metadata file and the control file; and
a search portion that extracts a recording position corresponding to a keyword in the content file by specifying the metadata files in which an entered search keyword is included, and referencing the control file;
wherein the recording position of the content file is the recording position in the recording portion. - View Dependent Claims (19, 20, 21)
