Abstract: A decoding system, a RGB video color converter and a method for color conversion of at least part of a decoded currently received YUV frame representing an image is provided. The currently received YUV frame includes image blocks and RGB color conversion is performed by storing a previous color conversion RGB image in a RGB buffer, the image being from an immediately preceding received decoded frame. Next, identifying is effected for identifying the image blocks of the decoded currently received YUV frame that are unchanged relative to corresponding previous image blocks in an immediately preceding received decoded frame. Thereafter, selectively performing YUG to RGB color conversion is effected only on the image blocks of the currently received YUV frame that are not unchanged relative to the corresponding previous image blocks.

Abstract: Digital video imagery is deblocked as a function of horizontal and/or vertically oriented pixels that share a common attribute (such as a corresponding pixel value). In particular, a deblocking filter can be selected from amongst a plurality of candidate deblocking filters as a function of the presence of pixels that are both adjacent to one another and that are substantially similar to one another. The selected deblocking filter can be applied as a function, at least in part, of a respective center of the pixels that are both adjacent and similar to one another. In one embodiment, luminance information is deblocked pursuant to a process that is different from a deblocking process that is used with chrominance information.

Abstract: The invention provides a system and a method suitable for adaptive post-processing of media data in an electronic device. The system comprises one or more post-processing modules (102,104,106,108,110) that perform post-processing of the media data. Each post-processing module comprises one or more processing modes having different complexities. The system also comprises an adaptive mode decision module (112) coupled to the post-processing modules (102,104,106,108,110). The adaptive mode decision module (112), in use, decides upon the suitable processing modes on the basis of values of one or more input parameters. The input parameters are representative of the state of the electronic device. Once the decision has been made, the adaptive mode decision module (112) sends control signals to the post-processing modules (102,104,106,108,110) in order perform the post-processing of the media data according to the selected processing modes.

Abstract: A decoding system (100), a RGB video color converter (130) and a method (200) for color conversion of at least part of a decoded currently received YUV frame representing an image is provided. The currently received YUV frame comprises image blocks and RGB color conversion is performed by storing (210) a previous color conversion RGB image in a RGB buffer (145), the image being from an immediately preceding received decoded frame. Next, identifying (250) is effected for identifying the image blocks of the decoded currently received YUV frame that are unchanged relative to corresponding previous image blocks in an immediately preceding received decoded frame. Thereafter, selectively performing (280) YUG to RGB color conversion is effected only on the image blocks of the currently received YUV frame that are not unchanged relative to the corresponding previous image blocks.
