Abstract: A hybrid video decoder has a hardware decoding circuit, a software decoding circuit, and a meta-data access system. The hardware decoding circuit deals with a first portion of a video decoding process for at least a portion of a frame, wherein the first portion of the video decoding process includes entropy decoding. The software decoding circuit deals with a second portion of the video decoding process. The meta-data access system manages meta data transferred between the hardware decoding circuit and the software decoding circuit.

Abstract: A hybrid video decoding apparatus has a hardware entropy decoder and a storage device. The hardware entropy decoder performs hardware entropy decoding to generate an entropy decoding result of a picture. The storage device has a plurality of storage areas allocated to buffer a plurality of entropy-decoded partial data, respectively, and is further arranged to store position information indicative of storage positions of the entropy-decoded partial data in the storage device. The entropy-decoded partial data are derived from the entropy decoding result of the picture, and are associated with a plurality of portions of the picture, respectively.
