Abstract: 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.

Abstract: 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.
