Abstract
Embodiments of the present invention disclose a transformation mode encoding and decoding method and apparatus. A correlation between the prediction mode and the transformation mode is used, and an optimal transformation mode candidate set is simplified, thereby saving resources when an index of an optimal transformation mode is encoded in encoding header information. In addition, encoding efficiency is higher when an encoding end elects a transformation mode.
