Abstract

The invention provides an adaptive spatial scalable coding method based on HEVC (high efficiency video coding) standard. According to the method, the reasonable lower sampling scheme is designed to realize the space scalability by analyzing the characteristics of video sequence and considering the size of a coding unit CU in the HEVC (high efficiency video coding); different prediction modes are designed aiming at the movement characteristics of the video sequence, the reducing code rate is predicted by the inter-layer motion; the effective inter-layer residual predication is used to reduce the residual information amount and enhance the compression property; the reasonable judgment rule is designed, and the inter-layer or in-layer predication coding is selected adaptively.
