METHOD AND APPARATUS ACQUIRING CHANNEL INFORMATION USING A BROADCAST DATA

摘要

PURPOSE: A device for obtaining channel information using broadcast data and a method thereof are provided to minimize additional connections with an existing broadcast system, thereby obtaining broadcast channel information. CONSTITUTION: An audio/video receiving unit extracts audio or video data from collected broadcast data. A sampling unit samples the extracted audio/video data. A preprocessing unit encodes the sampled data. A channel determining unit(160) compares audio or video sampling data for N broadcast channels from a channel identifying server with the encoded audio or video data. The channel determining unit obtains a channel identifier according to the comparison result.
