VIDEO PROCESSING APPARATUS CAPABLE OF GENERATING OUTPUT VIDEO PICTURES/SEQUENCE WITH COLOR DEPTH DIFFERENT FROM COLOR DEPTH OF ENCODED VIDEO BITSTREAM
First Claim
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 video data buffered in the storage device to generate output video pictures (sequence) to a display apparatus.

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 the control unit, and 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 video decoding mode to generate decoded video pictures (sequence) to the storage device. The video processor is coupled to at least the storage device, and arranged for processing picture data derived from the data buffered in the storage device to generate output video pictures (sequence) to a display apparatus.
