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 providing information about a service provider by using an electronic device displaying contents is described. Information corresponding to first service providers which are able to provide a service to a specific electronic device regardless of a location of the specific electronic device is displayed. The information corresponding to the first service providers is displayed enabled. Information corresponding to second service providers which are able to provide a service to a specific electronic device in a certain region is displayed. The information corresponding to the second service providers is displayed disabled. Regional information of the electronic device is set based on regional information received through a user interface unit or location information obtained by a location information module. The set regional information is transmitted to a server.
