An image processing method and system removes block artifacts in compressed image/video. Block artifacts are detected based on content analysis performed based on knowledge of the contents of the image/video. Then, a set of priority conditions is evaluated to generate a detection decision for each pixel at the block boundary. A higher priority is given to a short-term temporal processing result and a spatial processing result. The long-term temporal processing result and quantization information are treated as auxiliary information to adjust the strength of filtering. Depending on the result of the detection decision, appropriate filtering is applied to the pixel to remove the block artifacts.

A display system that displays a mixture of 2D and 3D video content is provided. A switching mechanism in the display system turns the 2D/3D mode of different portions of the screen on and off independently and automatically. Any type (2D, 3D, mixed) of video content can be displayed on any part of the screen simultaneously. The switching between different modes (2D, 3D, mixed) is performed automatically according to input control signals received from an internal device, or determined by a 2D/3D content detector in a computer, set-top-box, and/or cable/satellite tuner/receiver.

A video processing method and system that obtains, transmits, and processes digital video compression rate information between a video receiver such as a Set-top-box (STB) and a display device such as a TV set. The compression rate information is obtained by the video receiver and delivered to a compression noise reducer in the display device. The compression rate information provides an indication of how much compression noise might be embedded into an incoming compressed video signal and thus allows the compression noise reducer to reduce compression noise from the incoming video signal more effectively and efficiently.
