The purpose of this paper is to reduce the time that the receiver device takes to find the transmission frequency for the initial channel setting of receiving devices such as Digital TV which uses satellite broadcast. We propose two search algorithms based on the frequency allocation information of the transmission frequency of SCRs (Satellite Channel Routers) device. For all frequency combinations that a device can have, we compared the performance of the proposed algorithm and analyze the performance of the algorithm, which can help to reduce the channel setting time noticeably.
