Provided are an encoding system using motion estimation and an encoding method using motion estimation for achieving high-speed motion estimation according to a multi-processing unit. The encoding system using motion estimation, comprises a multi-processing unit calculating motion estimation on many macroblocks of an input image, a motion estimator estimating motion vectors of the macroblocks of the input image using the motion estimation on the plurality of macroblocks, previously calculated by the multi-processing unit, and an encoder encoding the image based on the motion vectors of the macroblocks, estimated by the motion estimator. According to the present invention, motion estimation to be used for motion estimation can be calculated in advance according to the multi-processing unit capable of processing high-speed parallel processing to reduce an image encoding time and improve an encoding speed.

Disclosed is a system and a method for maintaining broadcasting chip information regardless of device replacement in a USIM unlock environment where broadcast information can be automatically modified in response to device replacement. The method includes: transmitting terminal information on the second terminal and subscriber information corresponding to the first USIM card to a mobile communication information management server; when the terminal information is different from terminal information corresponding to the subscriber information, determining that there has been device replacement, and then providing the terminal information and the subscriber information to a broadcast information management server, by the mobile communication information management server; transmitting a request for modification of broadcasting chip information from the mobile communication information management server to a Conditional Access System (CAS), and extracting, by the CAS, broadcast information on the first broadcasting chip based on the subscriber information in response to the request; generating EMM information based on the broadcast information on the first broadcasting chip, and providing the generated EMM information to the second terminal corresponding to the terminal information; and modifying the information on the second broadcasting chip of the second terminal to information of the first broadcasting chip.
