Abstract: A video processing system comprises a video processor and an output buffer. When a new frame is to be written to the output buffer, the video processing system determines (12) for at least a portion of the new frame whether the portion of the new frame has a particular property. When it is determined that that the portion of the new frame has the particular property (14), when a block of data representing a particular region of the portion of the new frame is to be written to the output buffer, it is compared to at least one block of data already stored in the output buffer, and a determination is made whether or not to write the block of data to the output buffer on the basis of the comparison. When it is determined that the portion of the new frame does not have the particular property (16), the portion of the new frame is written to the output buffer.

Abstract: A data processing system comprises a video processor (3). The data processing system is configured to, when a new frame (10) is to be encoded by the video processor (3), determine for a sub-region of a set of plural sub-regions that the new frame (10) is divided into, whether the sub-region has changed from a previous frame (11), and to control the encoding operation for the new frame (10) on the basis of the determination, e.g. to avoid performing motion estimation.

Abstract: A video processing system includes a video processing unit (VPU) and one or more display processing units, all having access to external memory. Video data representing frames to be displayed is generated. The VPU generates pixel data representing the frames and stores it in memory. The display processing units then read the pixel data to display the frames. The VPU is configured to generate and store in memory pixel data representing reference frames for the sequence of video frames at the full resolution of the reference frame and also at at least one lower resolution to the full resolution.
