The present invention provides an improved video encoding and decoding method, which maintains the advantages of LCU-based filter parameter signaling as compared to frame-based filter parameter signaling, but considerably reduces signaling overhead. Therefore, signaling syntax is modified by grouping LCUs (Largest Coding Units) together for signaling employing a mapping function. Consequently, filter parameters no longer need to be signaled for each single LCU, but for a group of several LCUs. The syntax structure of the invention avoids redundancies present in the state of the art as far as possible and thus increases the information content of the syntax elements. At the decoder side, the mapping function is applied to infer information about the filter parameters to be applied to a current LCU from information encoded in different syntax structures.

Syntax and semantics for adaptive loop filter and sample adaptive offset

An image encoding method for encoding a multi-view image captured from a plurality of capturing views includes: generating a plurality of view identification information items each for identifying a plurality of display views that are a plurality of views used for display in an image decoding apparatus, by corresponding to each of a plurality of screen sizes used in the image decoding apparatus; and encoding the view identification information items.
