Dolby can be widely used in various consumer electronic products, TV stations, cinemas and other fields. The key point is that Dolby digital technology has become the standard of various international industry organizations or enterprise alliances.
Dolby digital technology was first selected as the standard by American Advanced Television Systems Committee (ATSC). Since then, dolby digital has become the standard of the International Telecommunication Union (ITU-R). At the request of Australian and other national broadcasters, the European Digital Video Broadcasting Organization (DVB) included dolby digital in its standard in 1999. The equipment with built-in dolby digital decoder and digital TV broadcasting with dolby digital audio all conform to DVB standard. Of course, the World DVD Forum also takes Dolby digital technology as the audio standard of its DVD products.
Dolby Laboratories has made a commitment to ATSC, ITU-R and DVB organizations to provide open and fair certification authorization. Due to the high integration of decoding chips, the application cost of dolby digital decoding circuit is almost negligible. In return for moderate royalties, Dolby Laboratories provides patent details and practical technology to consumer equipment manufacturers.
Close cooperation with Dolby enables these manufacturers to produce normal products in the fastest time, thus greatly reducing the development cost and shortening the time for new products to enter the market. Dolby trademark on the product is regarded as a symbol of high quality and reliability by consumers all over the world, which adds value to DVB products, especially retail set-top boxes which are very sensitive to price.
Dolby digital has become the strongest driving force of car audio.
Dolby directional logic matrix surround sound technology can obtain surround sound effects from stereo sources that cannot provide dolby digital audio, such as video tapes, analog TV broadcasts and music CDs. Dolby directional logic II and directional logic IIx can also obtain multi-channel surround sound effects from all stereo programs without special coding. Similarly, after encoding games and radio programs, special directional effects can be obtained through the decoding function of Dolby directional logic II. Here, Dolby directional logic II and directional logic Iix technology are developing in the field of car audio.
ProLogicII's natural surround sound is very suitable for car audio system. Whether you are listening to FM radio, cassette, CD or MD, ProLogicII can let you drive your car with five channels of sound. ProLogicII decoder can be added to the existing car audio system (such as FM radio /CD player) or used as a separate processor.
When you have a ProLogicII system in your car, you can enjoy stereo and natural audio-visual effects through its left, middle, right and surround speakers, instead of just hearing speakers like many car audio systems. At the same time, some ProLogicII systems also provide sound field adjustment functions such as central channel width control, spatial control and panoramic control. With these functions, you can make special optimization and adjustment according to your personal hobbies.
Since the popularization of Dolby noise reduction technology in cassette player more than 30 years ago, Dolby Lab has become a part of car audio system. Now, Dolby Laboratories is creating a new era of in-vehicle entertainment equipment. You may have experienced the strong sense of surround sound in movies or at home. Today, you can also feel the same shocking effect in the car entertainment system equipped with Dolby surround ProLogicII, DVD and even Dolby headphones. Some people call it a "flowing melody".
Through Dolby surround ProLogicII, dolby digital, MLP loss compression (MLP lossless? ) technology and the research and development of Dolby headset technology, Dolby Lab has become the strongest driving force for the innovation of high-quality in-vehicle entertainment equipment.
