Abstract: A method for transmitting and receiving a synchronization signal in a communication system is disclosed. An operation method of a terminal comprises the steps of: receiving, from a base station, a synchronization signal and an SS block including a PBCH; estimating y bits among x bits for indicating a number of a system frame on which the SS block has been transmitted, on the basis of a sequence used for the scrambling of the PBCH included in the SS block; decoding the PBCH included in the SS block so as to acquire z bits among the x bits for indicating the number of the system frame on which the SS block has been transmitted; and confirming the number of the system frame on the basis of the y bits and the z bits. Therefore, the performance of a communication system can be improved.

Abstract: Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.
