Method for providing media-content related information, device, server, and computer-readable storage medium for executing the method

A non-transitory computer-readable storage medium having embodied thereon a computer program for executing a method for providing media content-related information by using a device capable of accessing a server via a network, the method comprising:

• generating identification information of media content being reproduced by the device;
• transmitting the identification information from the device to the server;
• receiving at least one of key information and media content-related information, from the server, in response to the identification information;
• and
• providing a user of the device with the media content-related information regarding the media content based on the at least one of the key information and the media content-related information received from the server.

A method for providing media content-related information using a server that is accessed by at least one device via a server, the method comprising:

• detecting key information based on closed caption information of received media content in the server;
• generating identification information of media content based on which the key information is detected among the received media content in the server;
• synchronizing the identification information and the key information;
• storing the synchronized information in the server;
• searching, when identification information of media content is received from the at least one device, for identification information that matches the received identification information from among the stored identification information in the server;
• and
• transmitting, when the matched identification information is found, key information synchronized with the found identification information, from the server to the device.

• and
• transmitting, when the matched identification information is found, key information synchronized with the found identification information, from the server to the device.

A device, comprising:

• a media content-receiving unit for receiving media content;
• a reproducing unit for reproducing the received media content;
• a network interface unit for interfacing with a network;
• and
• a processor for generating identification information of media content that are currently being reproduced by using the reproducing unit, and transmitting the generated identification information to a server via the network interface unit, and providing, when at least one of key information and media content-related information is received from the server, the user with the media content-related information about the media content based on the received information, by using the reproducing unit.

A server comprising:

• a key information-detecting unit for detecting key information based on closed caption information of received media content;
• an identification information-detecting unit for detecting identification information of the media content based on which the key information is detected;
• a network interface unit for interfacing with a network;
• a processor for synchronizing the detected key information and the detected identification information and storing the synchronized information, and searching, when identification information of media content is received from at least one device via the network interface unit, for identification information that matches the received identification information among the stored identification information, and transmitting key information synchronized with the found identification information to the device via the network interface unit;
• and
• a storage unit for storing the key information and the identification information.
