Abstract: PURPOSE: A multi-view video system for three-dimensional stereo images and an image forming method are provided to view an object and an image on a three-dimensional display at various angles simultaneously. CONSTITUTION: A multi-view video system includes a pre-processor(30), a video compressor(31), a system multiplexer(32), a system demultiplexer(33), a video decompressor(34), a video intermediate image generator(35), and a three-dimensional display controller(36). The pre-processor corrects parameters due to differences among characteristics of cameras. The video compressor removes temporal and spatial redundancies among images output from the cameras. The system multiplexer makes independent video streams into one multiplexed stream. The demultiplexer restores the multiplexed stream into the independent video streams. The video decompressor decompresses images compressed by the video compressor. The intermediate image generator generates intermediate images of multi-view images. The display controller outputs a two-dimensional image on a three-dimensional display device.

Abstract: PURPOSE: A symbol clock recovery circuit of a multi-level modulation signal and a method thereof are provided to overcome problems in early-late clock recovery and to simplify hardware by enabling a symbol clock recovery of a multi-level signal. CONSTITUTION: A signal input to a late sampler(11), an early sampler(13) and an on-time sampler(21) are output to a timing error detector(22). The output of the timing error detector(22) is input to a voltage control oscillator(17). The output of the voltage control oscillator(17) is input to an early-late-on-time clock generator(23). The output of the early-late-on-time clock generator(23) is input again to the late sampler(11), the early sampler(13) and the on-time sampler(21).
