Abstract:
A terminal device acquires a part of an audio-visual content regenerated by a video display apparatus. The terminal device acquires contents information of the audio-visual content based on the part of the audio-visual content. The terminal device acquires the available enhanced service based on the contents information and regenerates the available enhanced service.
Abstract:
Provided are a video display device and a method of controlling the same. The method includes: obtaining an uncompressed audio-visual (AV) content; playing the uncompressed AV content through the display unit; obtaining content information of the uncompressed AV content on the basis of a section of the uncompressed AV content; obtaining an enhanced service on the basis of the content information; and playing the enhanced service through the display unit.
Abstract:
Provided are a video display device and a method of operating the same. The video display device request content recognition configuration information to a third party server that is not dependent on any single channel, and receives the content recognition configuration information from the third party server. The video display device extracts a plurality of content recognition configuration information items from the content recognition configuration information and configures the plurality of content recognition configuration information item in the video display device. The video display device obtains contents information of uncompressed content on the basis of the plurality of content recognition configuration information item, obtains an application on the basis of the content information, and executes the application.
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:
Provided is a method for receiving a broadcast service. The method includes: receiving a first packetized stream; extracting presentation time information from a header of the first packetized stream; extracting trigger information comprising a target service identifier and a trigger action from a payload of the first packetized stream; and performing the trigger action to an object corresponding to the target service identifier at a time indicated by presentation time information.
Abstract:
Provided are a video display device and a method of controlling the same. The method includes: obtaining an uncompressed audio-visual (AV) content; playing the uncompressed AV content through the display unit; obtaining content information of the uncompressed AV content on the basis of a content section of the uncompressed AV content; obtaining content change time information and enhanced service information on the basis of the content information; and determining a delay time for obtaining the next content information on the basis of the content change time information.
Abstract:
A method of receiving a broadcast service is provided. The method includes receiving uncompressed audio or video content, obtaining information regarding a channel of the uncompressed audio or video content on the basis of a part of the uncompressed audio or video content, and obtaining content and trigger information for the broadcast service by using the obtained information.

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.
