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.

Abstract: An image encoder includes a tone mapper, an enhancement layer and an image file generator. The tone mapper is used to generate a base image according to an enhanced image and red green blue (RGB) gains. The RGB gains are set close to or the same as each other. The enhancement layer is used to generate a tone curve and/or a gain map of the base image and the enhanced image according to the tone mapper and/or a group including the base image and the enhanced image. The image file generator is used to generate an image file according to the base image and at least one member of a group including the tone curve and the gain map.
