The present application relates to an apparatus for programmable video size reduction with dynamic image filtering for use in block-based video decoding system. is intended for use in handheld or mobile applications.The invention improves the image quality within low video memory requirements and allows for efficient decoding of higher resolution video to be displayed on a lower resolution display device. It consists of :a) Motion vector scaler,b) A block data decoder for producing a transformed block data,c) A block downsampler for downsampling the transformed block data,d) A frame memory for storing at least one downsampled frame of video data,e) Means for producing a downsampled frame of video by employing the downscaled motion vectors, the downsampled block data and downsampled frame of video.f) And a programmable dynamic image filter for filtering the downsampled frame of video and storing the filtered image in the frame memory for subsequent processing. |
