Abstract
A method for video decoding in a video decoding/de-interlacing display apparatus that utilizes a storage device having four frame buffers is provided. The method includes following steps: (a) decoding video data of a next picture; (b) if the next picture is a B picture, buffering the decoded video data of the next picture into a frame buffer of the storage device not stored with a reference picture nor a present display picture nor a previous display picture; and (c) if step (b) is not applicable, buffering the decoded video data of the next picture into a frame buffer of the storage device stored with the previous display picture.
