Abstract: The present invention relates to an apparatus and method for acquiring a viewing channel identifier when a viewer intends to participate in a video of a channel being viewed in a viewer participation broadcast service area. The apparatus of the present invention comprises: an audio/video-receiving unit which collects broadcast data of the channel being viewed by the viewer, and extracts audio or video data from the collected broadcast data; a sampling unit which samples the extracted audio/video data; a preprocessing unit which encodes the sampled data; and a viewing channel determination unit which compares the encoded audio or video data and audio or video sampling data for N broadcast channels, received from a channel identification server, and acquires a viewing channel identifier in accordance with the result of the comparison.

Abstract: PURPOSE: An AP(Access Point) selecting apparatus for optimizing performance in a wireless LAN(Local Area Network) and method thereof are provided to select the best throughput in a wireless network by considering of the throughput justice and time justice in an AP selecting algorithm. CONSTITUTION: A storage unit(110) stores an AP selecting algorithm. When a control unit(120) is connected to an AP which includes the best throughput in an entire WLAN, the control unit selects the AP and satisfies with a minimum demand bandwidth of a WLAN according to the AP selecting algorithm. A communication unit(130) wirelessly communicates with the selected AP.
