![]() ![]() For backwards compatibility, DTS-ES Discrete 6.1 back surround channel is ignored by DTS 5.1 equipment. A data flag signals the decoder (usually part of the receiver or pre-amplifier) that the bitstream contains an extra discrete back surround channel. This format offers better stabilization over the surround channels for complete 360-degree sound localization and surround pans (i.e., movement of sound in the surround channels from one side to another). This is a true 6.1-channel format, as the back surround audio channel is discretely encoded into the DTS bitstream. DTS-ES Matrix is completely backwards compatible with DTS 5.1 equipment. DTS-ES Matrix is compatible with THX Surround EX equipment. As such, the back surround channel is not discrete and therefore is not a true '6.1' format. The back surround channel is matrixed in similar fashion as the front center channel is matrixed into the front right and left channels in the Dolby Surround Pro-Logic technology. ![]() This is actually a 5.1-channel format with the back surround audio channel matrixed into those of the right and left surround. The same amount of audio encoded in Dolby Digital technology will use less disc space than if it was encoded in DTS. DTS audio data is not as compressed as Dolby Digital technology. Each of the 5.1 channels of decoded 20 bit DTS audio is superior to the linear 16 bit PCM audio used for conventional compact discs. This is an encode/decode system that delivers 6 discrete channels (5.1) of high quality 20 bit audio. Dolby Digital technology is commonly referred to as 5.1 (five point one) surround sound because it contains 5 full bandwidth (20 - 20,000 Hz) for the front, center and rear speakers, and one low frequency effects (LFE) subwoofer channel that is referred to as. This is a multi-channel surround system that contains 6 discrete channels of audio (left front, right front, center, left rear, right rear and LFE subwoofer). Processes the standard four channel Dolby ProLogic technology signal to reproduce 5.1 channel surround. This matrix multi-channel sound is encoded down to two channels for distribution, and then is decoded back to four channels when played back on a stereo source that decodes Dolby ProLogic technology surround. This consists of four discrete channels of audio (left, right, center and rear). Different surround sound types encode and decode this audio differently. Dolby supplies you with all the deliverables, testing, and technical support you need to make implementation easy.Surround sound consists of multi-channel audio. With universal capabilities, the Dolby MS12 also simplifies product development and testing. The Dolby MS12 includes licenses for the included Dolby technologies at a lower overall cost than separate licenses for existing Dolby Digital Plus, Dolby Digital, and transcoder options. ![]() Other new features of the Dolby MS12 include automatic pass-through of Dolby Digital Plus signals with Dolby Atmos® extensions and speech-gated Dialogue Enhancement, so your customers hear every word. For TV receivers, the Dolby MS12 can improve the sound of the small built-in TV speakers with enhanced bass response, speaker tuning for optimum performance, and virtual surround sound. Intelligent Loudness provides ITU-R relative and speech-gated loudness control and regulatory information for automated loudness management. The Dolby MS12 expands postprocessing capabilities. Netflix partners can find more information on the Netflix Ready Device Platform SDK. With available support for Dolby AC-4, Dolby MS12 also paves the way for next-generation audio experiences, so you'll be ready for future developments like ATSC 3.0 in the United States.Īnother important Dolby MS12 feature is native support for advanced audio use cases from Netflix. The Dolby volume-leveling technology provides a solution that keeps your customers happy. Although Dolby metadata includes dialnorm parameters, many sources don't include it, so loudness levels may vary widely. The Dolby MS12 also provides a consistent volume level across programs and sources to make listening more enjoyable. Comprehensive and cost-effective, it reduces the complexity of integrating multiple audio technologies into your receivers. The Dolby Multistream Decoder MS12 delivers the right solution. Yet consumers expect a seamless experience, whether they're watching traditional broadcast or streaming from the internet and PCs, or getting content from USB keys, game consoles, or mobile devices. Content now comes from a variety of sources - and this results in a variety of audio codecs. As TVs and set-top boxes evolve into multipurpose digital media platforms, you face a manufacturing challenge. ![]()
