With the rapid development of Internet technology, IPTV subscribers continues to grow. 2017 IPTV is among the country's second largest television transmission path, the 2018 has 154 million users. In addition to receiving content mode has changed, users desire for immersive content is also escalating. Personalized interaction and immersive audio experience has become a popular value-added services and content network transmission platform competing to supply customers.
Skyworth cooperation implemented on set-top boxes
This demonstration solution based IPTV STB MPEG-H scheme of the audio system implemented on set-top box SKYWORTH. It can bring through speakers or headphones, to bar users unparalleled immersive audio effects, significantly enhances the authenticity and appealing sound, and allows users to adjust the mix according to their preferences. These functions in order to bring new programming content viewing experience, for example: for the visually impaired has opened a special audio guide service; create a new profit model to customize the content supply and networking platforms, such as: providing additional commentary and sound into paying customers Effect.
Interactive function interface
With FraunhoferCingo, the sound source can be positioned at any audience can perceive the 3D space combined with head movement in the headset also put 3D audio effects. Immersive sound field in any VR experience plays a vital role, and Cingo technical support channels, and audio object ambisonic signal, this feature makes it the ideal user-generated content VR audio rendering technology.
China Unicom IPTV set-top box based on MPEG-H audio system solutions
March 2019, the Ministry of Industry and Information Technology, the State Administration of Radio and Television, the Central Radio and Television jointly issued the "ultra-high definition video industry development action plan (2019-2022 years)" clearly states that the three-dimensional sound codec for the future focus of the work of one. In order to accelerate floor and application of three-dimensional sound technology, Fraunhofer IIS roots in communications and consumer electronics industries. In the international, 3GPP (15th edition) and Virtual Reality Industry Forum (VRIF) are listed as the MPEG-H VR streaming audio only designated audio codec, and MPEG-H was in 2017 in Korea UHD service official business. In the country, Fraunhofer IIS joined the Chinese ultra-high definition video industry alliance, has become China's first technology provider 8K broadcast test vehicle, and participate led by China Electronics Standardization Institute "television receiving three-dimensional sound performance and technical requirements for equipment measurement method "standard drafting work. At the same time, three-dimensional sound as a Chinese television broadcast standard proponents, Fraunhofer IIS presented a draft standard based on MPEG-H audio to the government by the end of 2018.
Fraunhofer IIS business in China on behalf of Mr. Toni Fiedler, said: "The next-generation audio technology for all of the content production platform and transport networks are Fraunhofer IIS consistent endeavors, we are honored to partner China Unicom, the two sides together to achieve this vision. in just two months time will complete the MPEG-H China Unicom IPTV system integration work in, thanks to the research and development capabilities and efficient communication mechanism outstanding partners. I believe this will inevitably accelerate MPEG-H in Chinese mainland the actual landing progress, both sides look forward to have more in-depth cooperation. ", read more
