Abstract:
A video processing apparatus includes a control unit, a storage device, a video decoder and a video processor. The control unit is arranged for generating a color depth control signal. The video decoder is coupled to the storage device, and arranged for decoding an encoded video bitstream and accordingly generating decoded video pictures (sequence) to the storage device. The video processor is coupled to the control unit and the storage device, and arranged for referring to the color depth control signal to enable a target video processing mode selected from a plurality of supported video processing modes respectively corresponding to different output color depths, and processing picture data derived from the data buffered in the storage device under the target video processing mode to generate output video pictures (sequence) to a display apparatus.
