Simulation of 4K UHDTV via Satellite Link
Abstract: The prospect of 4K UHDTV grows over the next few years, operators and service providers will need to begin to recognize the importance of delivering the next-generation television experience that consumers demand. In this experiments, only two service scenarios with single band and single codecs with one of AVC and HEVC schemes are applied. With increased screen size resulting in a larger viewed angle, for identically shot content, the angular velocity of motion for UHDTV is greater than for HD. As a result, motion is more perceivable as discrete steps in position. Frame rate increases can reduce this effect, however does increase both baseband and compressed video bit rates. UHDTV operates at 50.0 or 59.94Hz progressive frame rates for video content, and 24.0 or 23.976Hz progressive frame rates for native movie content (e. g. any UHDTV successor to BluRay). Colloquially, the video formats are often known as 4Kp50 or 4Kp59.94. These equate to 4x the 3G-SDI line rates, so approximately 12Gbit/s.
