At the 2016 CES Electronics Show, UHD Alliance proposed a new generation of UHD standard UHD Premium, with 4K resolution, support for BT.2020 standard, HDMI2.0 standard, support for 10bit, support for 60 frames, HDR support, UHD Premium (UHD Premium ) Standards have become a major trend in the consumer electronics industry. The 4K ultra-high definition video service has become the basic business of major carriers. In the commercial process of ultra-high-definition high-end standards, how operators can avoid pipelines has become a hot topic.
UHD Premium has developed rapidly and has driven the rapid development of the entire industry chain. Currently three mainstream chip solutions such as Hass high-end product line, Rockchip, Amlogic crystal morning have launched ultra-high definition standard (UHD Premium) solutions.
Identify the five elements of the 4K high-level standard, indispensable: 4K resolution, BT2020, 10bit, 60 frames, HDR
The Ultra High Definition (UHD Premium) standard must meet the following five elements: It is based on 4K high resolution, supports BT.2020 standard, has 10 bit color depth, satisfies 60P frame refresh rate, and supports HDR. Only the 4K box device that satisfies these five elements at the same time can provide the best contrast and color, and brings 4K high-level standard (UHD Premium) ultra-high-definition images to shock.
4K high-level standard (UHD Premium) important basic indicators: support BT.2020
Earlier, the International Telecommunications Union Radiocommunication Sector (ITU-R) issued the BT.2020 standard for a new generation of ultra-high definition UHD (Ultra-high Definition) video production and display systems, re-defining the ultra-high definition of TV broadcasting and consumer electronics. The display of various parameters of the video indicators, to promote the 4K ultra-high definition home display equipment to further standardization.
4K high-level standard (UHD Premium) two key indicators: support 10bit, support 60P
The BT.2020 standard significantly improves the performance specifications of video signals relative to the BT.709 standard. For example, the depth of color increases from 8bit to 10bit. 10bit effectively improves the noticeable color gradation caused by the 8-bit video dither, further reducing the picture quality noise and making the TV box more clear in use. 10bit is significantly better than 8bit in terms of gradation and noise reduction.
BT.2020 uses a wider color gamut than conventional BT.709, covering 78.5%, while BT.709 covers only 38.5%, and BT.2020 color space has nearly doubled.
The BT.2020 standard specifies that the display resolution of Ultra-high definition ultra-high definition images is 38,402,160 and 76,804,320, and the supported refresh rate should be at least 60 P. This further enhances the exquisiteness and smoothness of Ultra-high definition images. 60P frame rate refresh rate can better display the motion picture.
4K High-Level Standard (UHD Premium) Picture Quality Sensitive Indicator: Supports HDR
HDR (High Dynamic Range Technology) is a major technological innovation in the field of film and television. Compared with the simple resolution enhancement, HDR will greatly enhance the picture quality of the playback content and bring more vivid picture effects. HDR features improved contrast while intelligently adjusting brightness, increasing color gamut, displaying more colors, and achieving better color effects. The 4K screen after HDR support vivid colors.
In the Internet era, operators only need to develop their pipeline business, which will inevitably be eliminated. It will make the pipeline thicker and stronger to carry more services, and it will be an effective transition path for composite digital service providers. Develop security business, provide copyright protection for UHD Premium content, end-user transaction process, and transaction information, provide an efficient security assurance mechanism, and participate in the development of upstream and downstream security standards, extending the 4K high-end standard (UHD Premium ) The industrial chain extends to the field of information services. Creating a quality network and doing a good job of providing intelligent pipelines will inevitably promote the sound and rapid development of the UHD Premium business.
