Development of Super Hi-Vision Eight-Channel Live Switcher - For production of a variety of ultra-high-definition video content

摘要

The authors will present the development of a new live switcher for Super Hi-Vision (SHV, 7680 × 4320-pixel video with 60 fps), which delivers a realistic viewing experience through live broadcasting with multiple SHV cameras and a live slow-motion system. This equipment has eight SHV inputs and four SHV outputs, capability to output down-converted 4K and HD images for monitoring, wipe/mix, superimposition, and digital video effects. A new signal processing device which divides an SHV image into 16 HD-sized partial images by pixels and simultaneously composites these images to achieve real time SHV video effects was developed. With this equipment, real-time, sophisticated composition of high-resolution large-screen video is possible. This is useful, not only for SHV live events, but also for program production, and it can reduce time and costs for post-production. These developments open up a new world of high-resolution, large-screen video effects.
