Abstract
A rendering device provides improved rendering responsiveness in multi-window display for rendering scenarios in which display sizes of images vary over time, while also reducing required memory bandwidth. The device comprises: a scenario processorfor interpreting a rendering scenario and calculating for each frame period a scale-down ratio for each of a plurality of pictures; a plurality of decodersfor decoding encoded data of a plurality of videos; a plurality of first scalers for scaling-down the decoded pictures using the scale-down ratios calculated by the scenario processor; a memoryfor storing the scaled-down pictures; a plurality of second scalersfor reading the scaled-down pictures from the memory and re-scaling the scaled-down pictures to match the scale-down ratios calculated by the scenario processor for a current frame period; and, a composing unitfor composing the re-scaled pictures.
