Abstract: Provided are a method of receiving an enhanced service and a video display device thereof. The method includes: receiving an audio-visual (AV) content; extracting first feature information from the received AV content; receiving a database including at least one of content information, enhanced service information, and an enhanced service, which correspond to the first feature information, from a first server by transmitting the extracted first feature information to the first server; storing the database received from the first server in a memory; extracting second feature information from the received AV content; and searching and obtaining one of content information, enhanced service information, and an enhanced service, which correspond to the extracted feature information, from the database.

Abstract: A video display apparatus pairs with a first terminal device. The video display apparatus receives an audio-visual content, and displays the audio-visual content. The video display apparatus acquires enhanced service information on an available enhanced service for the audio-visual content, and notifies an occurrence of the available enhanced service to the first terminal device.
