Abstract: Disclosed is a method for encoding and decoding a multi-layer video. The multi-layer video decoding method includes the steps of: decoding a first layer picture and storing the decoded picture in a decoded picture buffer; marking the first layer picture as a temporal reference picture; acquiring the interlayer RPS information of a second layer picture which has a first POC equivalent to that of the first layer picture and is predicted to be inter-layered by referencing the first layer picture; marking the first layer picture marked as a temporal reference picture based on the interlayer RPS information as a long-term reference picture; and making an interlayer prediction for the second layer picture by referencing the first layer picture marked as a long-term reference picture.

Abstract: PURPOSE: An entropy encoding/decoding method for processing an image of a layered structure and a device thereof, and a symbol encoding/decoding method and a device thereof are provided to perform the four symbols encoding at once, thereby increasing the coding gain. CONSTITUTION: A reordering unit reorders the coefficients of an input residual image(601). A low frequency component and a high frequency component are separated for the efficient entropy coding through the reordering. A symbol encoder and a level encoder perform the symbol encoding and the level encoding of the coefficients at least two symbol units at the same time(603).
