COMBINING MULTI-LAYERED BITMAP FILES USING NETWORK-SPECIFIC HARDWARE

摘要

Images and video can be produced by compositing or alpha blending a group of image layers or video layers. Increasing resolution or the number of (ayers results in increased computational demands. As such, the available computational resources limit the images and videos that can be produced. A computational architecture in which the image layers are packetized and streamed through processors can be easily scaled so to handle many image layers and high resolutions. The image layers are packetized to produce packet streams. The packets in the streams are received, placed in queues, and processed. For alpha blending, ingress queues receive the packetized image layers which are then z sorted and sent to egress queues. The egress queue packets are alpha blended to produce an output image or video.
