Provided are a processing device, an electronic device, and a method of outputting a video. The processing device includes a pull-down cadence detector configured to receive an input video stream generated by pulling down raw data from an external device, detect a pull-down cadence format indicating a rate at which the raw data is pulled down based on the input video stream, and output detection result information; and a pull-down cadence controller configured to output an output video stream having a second frame rate that is an integer multiple of a first frame rate of the raw data, based on the input video stream and the detection result information.

A method of motion estimation and motion compensation for a video processor includes steps of: detecting an input frame rate of a series of input frames; calculating a frame counting value, wherein the frame counting value represents the number of output frame periods between a current input frame and a previous input frame among the series of input frames; calculating a phase step, which is configured to generate a phase coefficient for generating an interpolated frame as an output frame of each of the output frame periods, according to the frame counting value; and generating the interpolated frame based on the current input frame and the previous input frame by using the phase coefficient. Wherein, the step of calculating the frame counting value, the step of calculating the phase step and the step of generating the interpolated frame are consistently performed until the input frame rate is successfully detected.

Video signals are received from multiple sources, including remote sources, and are collected at a central location for viewing and/or storage. The signals are transmitted to a central site as compressed, progressively-scanned streaming video signals, employing data rates in the range of 2-4 Mbps. 24 fps or less is used, and the frame rate may be variable or fixed. The source signal frame rate and image size may be different for each source signal, and the frame rate and image size of the source signal in the format stored may be different from the frame rate and image size in the format displayed. In formats utilizing less than 24 fps progressive scan multi-format, direct streaming is made possible from HDTV (16:9) data, enabling applications utilizing these higher levels of resolution. Application of these formats adjusts streams, enabling a video surveillance system to transmit streams to a remote viewing device.

A multi-format digital video production system is capable of maintaining full-bandwidth resolution of subject material while providing professional quality editing and manipulation of images intended for digital television and other applications, including digital HDTV programs and specialized video monitoring applications. This allows emerging broadband video transmission media, including Internet broadcast schemes, to overcome existing technology limitations. The approach facilitates high-quality/large-screen video production and monitoring through the use of conventional broadband channels, including those which currently only exhibit bandwidths on the order of 4 Mbps. In formats utilizing substantially 24 fps progressive scan multi-format system, direct streaming is made possible from HDTV (16:9) high-quality data, thereby expanding market applications which require these higher levels of resolution, bits per pixel, and so forth.

A calibration step is disclosed for use with a system and a method for creating a wide-screen picture-dominance effect in an auditorium located in a motion-picture theater. This is accomplished by an operator viewing a test image or images of horizontal and vertical lines projected onto a deeply-curved screen in said auditorium and adjusting the projection of said test image or images until the horizontal and vertical lines in said image or images appear straight and orthonormal, with the result that viewers watching motion pictures in said auditorium will observe images that appear wider than the physical confines of the auditorium in said theater.
