METHOD AND SYSTEM FOR PROVIDING ADDITIONAL INFORMATION ON BROADCASTING CONTENT
First Claim
1. A method performed by a voice feature extraction server for providing additional information on broadcast content to a viewer terminal connected through a data communication network, the method comprising:
- extracting audio feature data from the broadcast content and grouping it in a predetermined unit to store as voice feature information in a reserved storage space;
receiving voice feature data from the viewer terminal that is extracted by the viewer terminal in accordance with a predetermined method, based on an audio signal inputted through the viewer terminal;
detecting voice feature information corresponding to the voice feature data received from the viewer terminal from among the stored one or more pieces of voice feature information and transmitting the detected feature information to the viewer terminal.

Abstract
The present invention relates to a method and a system for providing additional information on broadcast content, and particularly, to a method and a system for providing additional information corresponding to broadcast content displayed on a television to a separate viewer'"'"'s terminal. The method for providing additional information on the broadcast content is performed by a voice feature extraction server and comprises the steps of: extracting audio feature data of the broadcast content to store voice feature information previously grouped in preset units in a provided storage space; and detecting voice feature information corresponding to the voice feature data received from the viewer'"'"'s terminal among the stored one or more pieces of voice feature information and transmitting the detected feature information to the viewer'"'"'s terminal, wherein the viewer'"'"'s terminal extracts the voice feature data from an input audio signal according to a preset method and transmits the extracted voice feature data to the voice feature extraction server, a temporal position corresponding to the voice feature data is determined from the received voice feature information, and the additional information is displayed at the temporal position.
