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 and the control unit, the video decoder arranged for referring to the color depth control signal to enable a target video decoding mode selected from a plurality of supported video decoding modes respectively corresponding to different output color depths, and decoding an encoded video bitstream under the target decoding mode to generate decoded video pictures (sequence) to the storage device; and

    a video processor, coupled to at least the storage device, the video processor arranged for processing picture data derived from the decoded video pictures (sequence) buffered in the storage device to generate output video pictures (sequence) to a display apparatus, wherein the encoded video bitstream is not fed into the video processor for decoding.
