Multiple international standards have chosen Dolby Digital

The key to why Dolby can be widely used in various consumer electronics, TV stations, movie theaters and other fields is that Dolby Digital The technology has become the standard for various international industry organizations or enterprise alliances.

Dolby Digital technology was first selected as a standard by the Advanced Television Systems Committee (ATSC) in the United States. Dolby Digital has since become an International Telecommunications Union (ITU-R) standard. At the request of broadcasters in Australia and other countries, the European Digital Video Broadcasting Organization (DVB) included Dolby Digital in its standards in 1999. Equipment with built-in Dolby Digital decoders and digital TV broadcasters using Dolby Digital audio All outputs comply with DVB standards. Of course, the World DVD Forum also uses Dolby Digital technology as the audio standard for its DVD products.

Dolby Laboratories has made commitments to ATSC, ITU-R and DVB organizations to provide open and fair certification authorization. Due to the high degree of integration of the decoding chip, the cost of Dolby Digital decoding circuit application is almost negligible. In return for a modest royalty cost, Dolby Laboratories provides patent details and practical expertise (know-how) to consumer device manufacturers.

Working closely with Dolby enables these manufacturers to produce working products as quickly as possible, thereby significantly reducing development costs and shortening the time for new products to enter the market. The Dolby trademark on products is considered a symbol of high quality and reliability by consumers around the world, adding value to DVB products, especially retail set-top boxes that are very price-sensitive.

Dolby Digital has become the strongest driving force for car audio

Dolby ProLogic matrix surround technology can replace Dolby Digital audio (such as video tapes, analog TV broadcasts and Get a surround sound effect from a stereo source such as a music CD). Dolby Pro Logic II and Pro Logic IIx also enable multi-channel surround sound effects from all stereo programs without the need for special encoding. Similarly, after encoding games and broadcast programs, special directional effects can be obtained through the decoding function of Dolby Pro Logic II. And here, Dolby Pro Logic II and Pro Logic Iix technologies are flourishing in the field of car audio.

Through the development of Dolby Surround ProLogicII, Dolby Digital, MLP Lossless compression (MLPLossless?) technology and Dolby Headphone technology, Dolby Laboratories has become the leader in this high-quality automotive entertainment The strongest driving force for equipment innovation.
