METHOD AND APPARATUS FOR ENCODING/DECODING SCALABLE IMAGE AT HIGH SPEED

摘要

Provided is a method and apparatus for encoding/decoding a scalable image at high speed. A scalable image processing method according to embodiments of the present invention comprises: calculating a position of an RL block in an RL picture; up-sampling the calculated RL block; and encoding or decoding a current PU by referring to the up-sampled RL block. Accordingly, the present invention can enhance an encoding/decoding speed through reducing an amount of consumption of a memory by an encoder/decoder and decreasing an amount of calculation, by performing an up-sampling process on only a required block in the PU encoding/decoding process.
