APPARATUS FOR RADIO FREQUENCY RESOURCE MANAGEMENT AUTOMATION OF AN INTERNET PROTOCOL (IP) MULTIMEDIA SUBSYSTEM (IMS)-BASED WIRELESS VIDEO SURVEILLANCE SYSTEM AND A METHOD THEREOF, CAPABLE OF MAXIMIZING VIDEO QUALITY AS MINIMIZING THE USAGE OF RADIO RESOURCE

摘要

PURPOSE: An apparatus for radio frequency resource management automation of an internet protocol (IP) multimedia subsystem (IMS)-based wireless video surveillance system and a method thereof are provided to use the resource of the IMS-based wireless video surveillance system efficiently.;CONSTITUTION: A communication part receives target reference of video quality from a server (240). A control part judges whether the video quality complies with the target reference on the basis of Peek Signal to Noise Ratio (PSNR) or frame rate. When the video quality does not comply with the target reference, the control part requests allocation of additional resource to the server. When the video quality does not comply with the target reference, the control part changes compression mode of the video.;COPYRIGHT KIPO 2013
