Dolby Lab was founded in 1965, and has a long-standing reputation for its high-quality audio and surround sound technology. Whether vertically, from the content creation in the recording studio to the production and distribution of media programs to the broadcast of programs, or horizontally-movies, radio and television, games and mobile phones, it is indispensable in all fields involving entertainment experience. In the field of audio technology, Dolby is a powerful and ubiquitous brand. It is said that more than 4 billion consumer products around the world integrate Dolby's technology.
Of course, the solution is not a free lunch, and Dolby will also charge the corresponding licensing fee. The specific rate is related to the quantity of products. "A 5,000-yuan PC (the charge) is about one thousandth." Dolby continues to promote the application of its technology in China and expand the scope of "rent collection" in China. For example, 1 1 in the existing 13 high-definition channel in China adopts Dolby's audio coding and decoding technology, and high-definition pictures inevitably require better sound quality. Operators do not have many choices for relevant mature technologies. Once established as a standard audio technology, manufacturers in the industrial chain such as set-top boxes and televisions need to obtain authorization from Dolby and pay related fees. Dolby is actively promoting its new generation +(Dolby Digital Plus, which can provide 7. 1 channel surround sound [47.70 -0. 1 1%] for HDTV broadcasting, resulting in a richer and more vivid experience, and the bandwidth required for the same sound quality can be greatly reduced. At present, it has become a mandatory audio format of the American Advanced Television Systems Committee. It is also the mandatory standard of digital TV and IPTV in ETSI (European Telecommunications Standardization Association) standard, and IPTV and other applications are also an important part of "triple play" in China.
Dolby is not "big", but a "small and beautiful" technology company. However, although the sparrow is small and complete, its global operation, the layout of the whole industrial chain, standard management and control are beyond the reach of most enterprises, even if its focus is not in the most conspicuous part of the spotlight.
