Claim Text:
1. A video processing apparatus, comprising: a control unit, arranged for generating a color depth control signal; a storage device; a video decoder, coupled to the storage device, the video decoder arranged for decoding an encoded video bitstream and accordingly generating decoded video pictures (sequence) to the storage device; and a video processor, coupled to the control unit and the storage device, the video processor 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 decoded video pictures (sequence) buffered in the storage device under the target video processing mode to generate output video pictures (sequence) to a display apparatus, wherein the encoded video bitstream is not fed into the video processor for decoding; when the target video processing mode corresponds to a first output color depth, the output video pictures (sequence) having the first output color depth are generated to the display apparatus; and when the target video processing mode corresponds to a second output color depth different from the first output color depth, the output video pictures (sequence) having the second output color depth are generated to the display apparatus.
