First Claim
1. A method of operating a video display device including a display unit, the method comprising:
- obtaining an uncompressed audio video (AV) content;
playing the uncompressed AV content through the display unit;
extracting a fingerprint from a part of the uncompressed AV content;
obtaining a first response, from a content recognition server based on the fingerprint,wherein the first response includes a timestamp of the uncompressed AV content, and an address of an enhanced service providing server;
transmitting a query, to the enhanced service providing server using the address of the enhanced service providing server;
receiving a second response from the enhanced service providing server,wherein the second response includes an address of an enhanced service application, a request period for the enhanced service application, and information on an acquisition path of the enhanced service application;
receiving the enhanced service application using the address of the enhanced service application; and
executing the enhanced service application,wherein the enhanced service application comprises a function for a bookmark of the enhanced service application, andwherein the executing the enhanced service application comprises;
storing the bookmark of the enhanced service application, wherein the bookmark includes a time when the bookmark is set, andexecuting the enhanced service application, that is not dependent on any single service, corresponding to the bookmark, when a user input for the bookmark is received.
