At the end of 2017, the nation’s first 4K ultra high-definition television test channel was formally launched in Guangdong Radio and TV Station and became a milestone in the history of China’s 4K development. This 4K storm will provide us with more vivid pictures, more special effects, more rich scenes, and performances. More delicate audio-visual feast. In the 4K ultra-high definition channel system of Guangdong Broadcasting and TV Station, Zhong Ke Dayang successively swept the 4K broadcast and the 4K post-production editing system. Among them, the editing-based post-production editing system in the 4K project of Guangdong Taichung won the bid for the programming of the program content in Taiwan's 4K Ultra HD channel. We have released detailed reports on Ocean’s 4K broadcast project. Today, Xiao Bian came to discover why the 4K post-production non-linear editing system in the ocean has a powerful place. 4K means that the video has better clarity and can show more details. The production of 4K TV programs requires the rapid application of various technological processes in the process. The difficulty lies in the large amount of production, high production costs, and the immature stability of technology and equipment, and it is difficult to guarantee the output of the content without delay. To meet the requirements of storage, editing, and bandwidth, it is very difficult to formulate a system-level process that satisfies 4K ultra high definition editing, HDR, color management, and 4K broadcasting for Taiwan. Ocean actively responded to the requirements of the Guangdong Provincial Government to promote the development of 4K ultra-high definition television, content creation and technology development, and cooperated with various departments and agencies in Guangdong Province to bring profound changes to the domestic 4K television production process. The picture shows the field test Perseverance, innovative technology Dayang engineers conducted several discussions with the Taiwan authorities and formulated different business plans. For the product standards and technology reserves that have never existed before, Dayang R&D team has provided efficient solutions for 4K+HDR production around the clock. During several months of technical testing, the Ocean Technology team cooperated with the Provincial Department of Production, the Department of Information, and the Department of Broadcasting to carry out comprehensive index testing and product testing, eventually resulting in software functions, humanization, real-time editing, and monitoring. Looking at the plan and many other aspects exceeded the user's expectations, Ocean's launch of a new generation of color management system has created a new situation for domestic high-quality 4K+HDR production. The picture shows the engineers from the ocean and Guangdong Taiwan technical staff to discuss the process plan Compatible with package, keep improving In addition to the traditional resolution improvement of 4K ultra-high definition television programs, the requirements for the performance of color gamut, high frame rate playback, and high dynamic range of video images have also increased. In order to meet these "new challenges", Ocean's new 4K is not Prepared to give birth ~ > Compatible with SDR and HDR production, meet the highest XAVC 50P frame rate, edit 4 layers of video, subtitles, color rendering in real time. > Satisfy the industry's mainstream PQ and HLG production, compatible with dual-channel editing of SDR and HDR. > The color space Rec.2020 that meets international standards can perform accurate color gamut conversion between UHD/HD/SD without any loss of quality. > With professional custom color palette, you can precisely control the color adjustment parameters and fully demonstrate your artistic creativity. > Support 5.1 & 7.1 surround sound production and Dolby certification technology, with the National Press, Publication, Radio, Film and Television Administration of the loudness control function, to meet the timeliness of audio in 4K program production, so that inspiration to express their feelings. Innovative technology leads the future > At present, HDR, Wide Color Gamut (WCG) and High Frame Rate (HFR) have become the new generation TV keywords. Ocean's latest 4K products follow new industry standards and incorporate new technologies into them. > The color management system co-developed by Ocean and Guangdong Taiwan can be independently, accurately, and freely configured. After rigorous testing and evaluation, it has received unanimous praise from Taiwanese leaders and related technical leaders. > Support the production and export of PQ and HLG standard documents; > Support intelligent color recognition and color conversion; > Original and powerful color conversion process and management system; > Compatible with mainstream HDR monitoring standards and equipment; > The 50/60P production standard meets the smooth production of HFR, captures perfect moments, and supports the Rec.2020 wide color gamut. Ocean has always been the industry's first vendor to implement a full-process 4K complete solution, and has been the industry leader in 4k production and 4K broadcast. In the 4K project of Guangdong Taichung, Ocean 4K post-production products created a high-quality 4K+HDR solution, while 4K broadcast video server, 4K video and audio processing platform, ocean 4K screen consistency, 4K four election one Static IP switching equipment and a series of innovative R&D products with independent intellectual property rights opened the key link of the 4K broadcast control program. In the future, Ocean will continue to strengthen its deep cooperation and cooperation with Guangdong TV in the 4K field to help it deepen the media-side structural reform of the radio and television media and seize the commanding heights of future industrial development.
