Toni Fiedler, representative of FraunhoferIIS China, was very excited in recent days and kept chatting with business partners who came to consult on the CCBN booth. At the booth, Fraunhofer brought China the first encoder to support MPEG-H technology, which is an encoder system in cooperation with digital video. On the booth, together with partner Merging Pyramix, a digital audio workstation supporting MPEG-H was jointly demonstrated. At the same time, it cooperates with two real-time monitoring companies Telos and Junger Audio to support Fraunhofer's technology and provide related equipment, hoping to better help the radio and television to build an ecosystem. In addition, Fraunhofer IIS also set up a special audio-visual room, let everyone feel the charm of MPEG-H audio technology more intuitively.
Of course, his excitement is far from that. Also on CCBN, Ding Wenhua, academician of the Chinese Academy of Engineering, said that China ’s 3D Audio standard will be promulgated soon, which will effectively lead the development of China ’s ultra-high-definition audio industry and drive the development of the consumer electronics terminal industry. In terms of audio coding, a 16-channel three-dimensional sound transmission system is established, coexisting with the existing 6-channel surround sound transmission system; China's 3D Audio standard transmission coding is compatible with MPEG-H, so there is no obstacle to the coding adaptation of overseas program Internet services.
This means that Fraunhofer will undertake the audio transmission work for China's next-generation audio standard, bringing infinite possibilities to Fraunhofer IIS. Since 2015, Fraunhofer IIS has actively participated in the formulation of China ’s three-dimensional sound standard. In response to the needs of the Chinese broadcasting market, combined with its rich practical experience in the field of international standards, it has recommended the next generation of radio and television audio for the Chinese market. Solution: MPEG-H TV audio system.

Who is Fraunhofer IIS?Some people are still unfamiliar with Fraunhofer IIS, but when it comes to MP3 and HE-AAC, there is nothing you do n’t know. It is the credit of Fraunhofer IIS.
Founded in 1949, the Fraunhofer Institute is the largest applied research institution in Europe, with 69 institutes, 24,500 employees, and an annual budget of 2.2 billion euros. "Fraunhofer is to commemorate the German physicist Fraunhofer. He is not only a scientist but also responsible for the industrialization of scientific research products, so we have always adhered to his spirit and continuously transferred R & D success to the market." Toni Fiedler said.
The full name of Fraunhofer IIS is Fraunhofer InsTItute of Intergrated Circuits, which seems to be related to IC but is actually a research institute dedicated to the development of audio solutions.
As shown in the figure, these standards were all born in Fraunhofer IIS.
What is the MPEG-H audio standardMPEG-H is a set of standards developed by the ISO / IEC Motion Picture Experts Group (MPEG) and includes 1 digital container standard, 1 video compression standard, 1 audio compression standard, and 2 conformance test standards.
At present, MPEG-H is adopted in both ATSC 3.0 and DVB standards.
Toni Fiedler said that currently in South Korea, the United States, Europe, Southeast Asia and Japan, have adopted the MPEG-H standard.
Especially at the South Korean Winter Olympics, MPGE-H audio transmission is used, and users can freely select commentary channels.
Fiedler introduced that currently Fraunhofer IIS mainly adopts three cooperation methods in South Korea. The first is to cooperate with equipment manufacturers to provide codec equipment; the second is to cooperate with TV manufacturers for product design; the third is to cooperate with radio and television organizations To train more sound engineers.
Cooperation with ChinaMr. Toni Fiedler said: "In order to enable Chinese consumers to experience the excellent audio experience brought by MPEG-H technology as soon as possible, the Fraunhofer IIS China team actively promotes the integration of MPEG-H TV audio system and China's radio and television supporting equipment, and participates in compliance with China The market's 3D sound standard setting work and close communication with TV stations across the country, we believe that once the standard is released, we can help the TV station to quickly produce content that supports the next generation of broadcast TV technology, and bring support to China 3D together with equipment manufacturers Sound technology in consumer electronics and professional equipment. "
At present, chip manufacturers including MStar, Realtek, Huawei HiSilicon, etc. have all been deployed in this field. "We provide code to semiconductor manufacturers, provide packaged supporting solutions, and also provide testing and certification services for TV manufacturers." Fiedler said: "In addition to the player, the front end and the transmission end will also do training, in addition, we also pay attention to the Internet OTT transmission. "This also explains why at the CCBN exhibition, Fraunhofer IIS should bring so many partners together.
As shown in the figure, in the current cooperation framework, Fraunhofer and Jebsen Century jointly provide MPGE-H audio, of which rendering work is mainly provided by Jebsen Century.
About the experience effect of MPEG-H audioThe author participated in the trial listening to the effects including the sound bar and headphones, which can be said to be very magical. Merging Pyramix engineers said that since the MPEG-H standard has 16 channels, in addition to 5.1 channels, there are ten channels that can transmit resources including various sound effects and voice. Through the sound bar, you can also easily achieve 3D stereo effects without the need for professional configuration and additional asset purchases.
A 3D printer is a device that can "print" real 3D objects. The function is the same as the laser forming technology. It uses layered processing and overlay molding, which means that 3D entities are generated by adding materials layer by layer, which is the same as traditional material removal processing. The technology is completely different. With reference to its technical principles, it is called a "printer" because the layering process is very similar to inkjet printing.
