Image decoding and encoding equipment and bit transmission methods

Abstract

This invention relates to a method for decoding and encoding images and a method for transmitting bit streams. Specifically, the image decoding method may include the following steps: dividing the current encoded image block into multiple encoded image blocks such that the encoded image blocks divided from the current encoded image block are within the current frame when the current encoded image block is outside the boundaries of the current frame; The first syntactic element analysis indicates whether the current encoded image block is divided into sub-blocks or whether the current encoded image block meets a predefined condition; and determines the splitting mode of the current encoded image block based on the syntactic element.
