Abstract
(EN)
The present invention comprises a video decoding device and method. Said method comprises: reading and decoding control information in a video stream; reading a video stream packet in the video stream according to the control information; at least according to the control information, reading, from a first temporary storage block of a memory module, corresponding pixel data in a first reference picture, storage content in the first temporary storage block being stored in sequence; performing decoding according to the video stream packet and according to the corresponding pixel data in the first reference picture, so as to generate pixel data of a decoded picture; and when performing decoding, transferring the pixel data of the decoded picture to a post-processing circuit for post-processing, and storing the pixel data of the decoded picture into the first temporary storage block according to the control information, so as to replace the storage content in sequence from the forefront storage content in the first temporary storage block.
