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. This provides selected RGB converted blocks for the current frame and then selectively updating image blocks in the buffer with selected RGB converted blocks for the current frame is performed. The resulting RGB image is then displayed on a display module.

Decoding system, video color converter and method thereof

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.
