In recent years, with the rapid development of Internet services and applications, the mobile communication industry faces enormous opportunities and challenges. The communication industry will integrate innovative technologies such as 5G, big data, Internet+, Internet of Things technology, virtual reality, smart city, and smart phones to build a new intelligent industrial structure and bring better mobile Internet experience to users. At the same time, the global VoLTE market has entered an explosive growth phase. Since 2015, China's three major operators have launched this field, and have started the commercialization of VoLTE.
During the PTEXPO period, Fraunhofer IIS demonstrated innovative audio processing technology that not only enables operators to differentiate their products and services, but also significantly enhances the user's calling experience and extends the immersive audio experience to VR devices.
Enhanced Voice Service (EVS) opens the global commercial process
Enhanced Voice Service (EVS) is a new 3GPP VoLTE codec developed jointly by Fraunhofer IIS. In addition, EVS is the designated codec for ultra-wideband services in the GSMA VoLTE standard. EVS delivers full HD voice quality, making voice calls comparable to today's digital media services. Integrating cutting-edge voice and audio coding technology, EVS brings significantly better voice and background sound quality than AMR-WB, and has superior anti-jamming capability under poor network conditions. EVS delivers optimized network capacity at an unbeatable low bit rate.
At the same time, EVS technology has begun to be promoted among global operators. US operator T-Mobile, Japanese operator NTT DoCoMo and Germany Vodafone have applied EVS technology in VoLTE networks and supported a variety of smartphones and chipsets.
Mr. Toni Fiedler, Fraunhofer IIS China representative, said: "In recent years, the burgeoning voice service has been plagued by traditional operators. The root of innovation is to provide users with better services and more competitive products. As audio We are very optimistic about the development prospects of VoLTE and mobile internet in the Chinese market. We are also looking forward to introducing the world's top audio technology to China.
Fraunhofer IIS End-to-End VR Audio Solution
Fraunhofer IIS end-to-end VR audio solutions deliver immersive realism and immersive sound for VR devices and applications. With the headphones, the Fraunhofer Cingo can also play 3D sound effects in any three-dimensional space that can be perceived by any listener.
The MPEG-H audio standard is the best partner for Cingo audio, which delivers immersive sound to mobile devices using 2D surround sound transmission bit rates in virtual environments. In addition, MPEG-H is capable of supporting channels, audio objects, and high-order high-fidelity signals.
Mr. Toni Fiedler, Fraunhofer IIS China representative, said: "VR audio is an exciting challenge for all companies in the ecosystem. We are honored to be at the forefront of technology development and participate in it. Recently, our VR audio Technology has been favored by many Chinese companies. At the IFA exhibition in Berlin in 2016, TCL Communications announced the adoption of Cingo technology on its Alcatel VISION equipment.
