Fraunhoferiis Chinese regions Toni Fiedler has been very excited in recent days, and chatting with business partners who come to consult on the CCBN booth. On the booth, Fraunhofer brought China's first encoder that supports MPEG-H technology, an encoder system that cooperates with digital video. On the booth, there is also a joint display of MPEG-H with a digital audio workstation that supports MPEG-H with a partner Merging Pyramix. At the same time, with two real-time listeners, Junger Audio, support Fraunhofer technology and provide related equipment, hoping to help build an ecotropic circle with powerful power and electricity. In addition, Fraunhofer IIS also set up an audio-visual room, making everyone more intuitively feeling the charm of MPEG-H audio technology.
Of course, his excitement is still not the case, and also on CCBN, the Chinese Academy of Engineering, Ding Wenhua said that China's 3D AUDIO standard will be promulgated, will effectively lead China's super high-definition audio industry development, and drive consumer electron end industry development, specifically On the audio coding, the 16-channel three-dimensional sound transmission system is established. It is complicated with the existing 6-channel surround transmission system; China 3D AUDIO Standard Transmission Coding is accompanied by MPEG-H, so the encoding adaptation of overseas program Internet services does not have obstacles.
This means that China's next-generation audio standard will be brought to audio transmission by Fraunhofer, bringing Fraunhofer IIS unlimited possible. Since 2015, Fraunhofer IIS actively participated in the development of China's three-dimensional sound standards, in response to the demand for radio and television markets with Chinese characteristics, combined with its rich practical experience in international standards, and recommended next-generation radio and TV audio for the Chinese market. Solution: MPEG-H TV audio system.

Who is Fraunhofer IIS?
Some people are still very unfamiliar with Fraunhofer IIS, but mention MP3, mentioning HE-AAC, not knowing, this is behind Fraunhofer IIS.
Fraunhofer Research Institute was established in 1949, a largest application research institution in Europe, with a total of 24,500 employees, an annual budget of 2.2 billion euros. "Fraunhofer is to commemorate the German physicist Fraunhofer. He is not only responsible for the industrialization of research products, so we have been adhering to his spirit, and the R & D is successfully transferred to the market." Toni Fiedler said.
Fraunhofer IIS is full of Fraunhofer Institute of Intergrated Circuits, which looks related to IC but is actually a research institute specializing in audio solutions.
As shown, these standards were born in Fraunhofer IIS.
What is the MPEG-H audio standard?
MPEG-H is a set of standards developed by ISO / IEC Dynamic Image Expert Group (MPEG), including 1 digital container standard, 1 video compression standard, 1 audio compression standard, and 2 consistency test criteria.
MPEG-H is currently used in the ATSC 3.0 and DVB standards.
Toni Fiedler said that MPEG-H standards were adopted in Korea, the United States, Europe, Southeast Asia and Japan.
Especially at the Korean Winter Olympics, the user can choose to explain the channel with MPGE-H audio transmission.
Fiedler introduced that Fraunhofer IIS has maintained three ways in South Korea. The first is to cooperate with equipment manufacturers to provide codec devices; the second is to cooperate with television manufacturers to carry out product design; third is to cooperate with Radio and Television Institutions Training more audio engineers.
Cooperation with China
Mr. Toni Fiedler said: "In order to enable China's consumers to experience the excellent audio experience from MPEG-H technology as soon as possible, the Fraunhofer IIS China team actively promotes the MPEG-H TV audio system and the integration of China's radio and television supporting equipment, participating in China. The three-dimensional standards of the market work and carry out close communication with TV stations across the country. We believe that once the standard is released, we can help TV stations to quickly produce the content of the next generation radio and television technology, and bring support with equipment manufacturers to support China 3D Voice technology consumer electronics and professional equipment. "
At present, MSTAR, REALTEK, Huawei Haisi and other chippers have been laid out in this area. "We provide code to the semiconductor manufacturers, providing packaging solutions, but also provides test certification for TV vendors." Fiedler said: "In addition to the playback, front and transport terminals will also do training work, and we also pay attention to the Internet OTT transmission. "This also explains why Fraunhofer IIS will bring so many partners at the CCBN show.
As shown in the figure, the current cooperation framework, Fraunhofer and Jiecheng centuries jointly provide MPGE-H audio, where rendering work is mainly provided by Jiecheng Century.
About MPEG-H audio experience
The author participated in the audio of the effect, including the sound and headphones, can be said to be very magical. The Merging Pyramix engineer said that since the MPEG-H standard has 16 to 5.1 channels, there are ten channels that can transmit resources, including various sound effects, and speech. By sound, you can easily implement 3D stereo effect without professional configuration and additional asset purchase. Technology area
