Method and system for providing additional information on broadcasting content
First Claim
1. A method performed by a viewer terminal for providing additional information on broadcast content to a viewer, the method comprising:
- extracting n-th voice feature data (where n is a natural number) from an audio signal that is inputted through the viewer terminal in a predetermined method to transmit it to a voice feature extraction server that is connected through a data network;
receiving, from the voice feature extraction server, n-th voice feature information corresponding to the n-th voice feature data from among voice feature information in which audio feature data of the broadcast content is grouped in a predetermined unit;
determining an n-th temporal location relevant to the n-th voice feature data from the received n-th voice feature information that corresponds to the n-th voice feature data;
displaying the additional information related to the n-th temporal location where n is a natural number;
when a predetermined event occurs, extracting (n+1)-th voice feature data;
detecting (n+1)-th voice feature information corresponding to the (n+1)-th voice feature data from among one or more pieces of pre-stored voice feature information;
determining the n-th temporal location related to the (n+1)-th voice feature data from the (n+1)-th voice feature information;
displaying the additional information related to the (n+1)-th temporal location;
when the voice feature information corresponding to the (n+1)-th voice feature data is not detected from among one or more pieces of pre-stored voice feature information, transmitting the (n+1)-th voice feature data to the voice feature extraction server; and
receiving the (n+1)-th voice feature information corresponding to the (n+1)-th voice feature data from the voice feature extraction server.

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.

6. A viewer terminal configured to:
-
extract n-th voice feature data (where n is a natural number) in a predetermined method from an audio signal that is inputted to transmit it to a voice feature extraction server that is connected through a data network; receive, from the voice feature extraction server, n-th voice feature information corresponding to the n-th voice feature data from among voice feature information in which audio feature data of the broadcast content which is received by the voice feature extraction server is grouped in a predetermined unit; and determine an n-th temporal location related to the n-th voice feature data from the received n-th voice feature information that corresponds to the n-th voice feature data, wherein the viewer terminal comprises a display unit configured to display additional information relevant to the n-th temporal location, wherein the viewer terminal is configured to;
when a predetermined event occurs, extract (n+1)-th voice feature data;
detect (n+1)-th voice feature information corresponding to the (n+1)-th voice feature data from among one or more pieces of pre-stored voice feature information; and
determine the n-th temporal location related to the (n+1)-th voice feature data from the (n+1)-th voice feature information,wherein the display unit is configured to display the additional information related to the (n+1)-th temporal location, and wherein the viewer terminal is configured to;
when the voice feature information corresponding to the (n+1)-th voice feature data is not detected from among one or more pieces of pre-stored voice feature information, transmit the (n+1)-th voice feature data to the voice feature extraction server; and
receive the (n+1)-th voice feature information that corresponds to the (n+1)-th voice feature data from the voice feature extraction server. - View Dependent Claims (7, 8, 9)
