摘要： A transmission rate adjustment device for supplying MPEG-TS at a desired transmission rate includes: a buffer; a buffer write unit for both sequentially writing to the buffer transport packets of the transport stream that have been read from an MPEG2-TS file and detecting time stamps in the transport stream; and a buffer read unit for transmitting to the MPEG decoder transport packets that have been sequentially read from the buffer at a transmission rate determined by a clock obtained by frequency-dividing a system clock of the MPEG decoder by a frequency division rate designated by a frequency division rate signal. The buffer read unit not only inserts NULL packets between transport packets, but also rewrites time stamps when adjustment cannot be realized by merely inserting the NULL packets.

摘要： A projector has a plurality of cameras for adjusting the focus of projected images, correcting projected images that are distorted when images are projected from the projector when it swings from side to side and tilts or when images are projected onto a shaped surface of a projection object, and correcting projected images so that to match the outer profile of the screen if the screen is used as a projection object. The projector has a projection device having a projection lens, a focus adjuster for adjusting the focus of the projection lens, a zoom adjuster for adjusting the zooming of the projection lens, an imager having a plurality of cameras for capturing respective images of a projection object, a projection area calculator for calculating a projection area of an image depending on the distance from the projection lens based on the zoomed position from the zoom adjuster, a three-dimensional position detector for detecting the three-dimensional position of a predetermined object point corresponding to identical object points in the respective images captured by the cameras from the images captured by the cameras and the projection area of the image calculated by the projection area calculator, and a distance detector for detecting the distance up to the object point from the three-dimensional position of the predetermined object point.
