Watching movies is an activity that is so normal to us who live in the modern days. With the video technology constantly developing, the movie we watch these days are so much better in every way than the ones we watch ten years ago. Only a few years, the mainstream resolution for videos has evolved from 720P to 1080P, and then to 2K and 4K and even higher. However, when watching a movie or a video, visual resolution is not the only factor that could determine your watching experience and the quality of the video. The sound effect is just as important as visual effects. It does not matter whether you are watching a regular 2D video or a 3D movie or even a VR video, a realistic sound system is a crucial factor of your watching experience. Dolby TrueHD and DTS are two kinds of great sound systems that can boost your watching experience of a movie. Today we are going to talk about the Dolby TrueHD and DTS, and everything you need to know when you want to enjoy a movie with Dolby TrueHD or DTS sound system.
Part 1: What are Dolby TrueHD and DTS?
Dolby Laboratories, Inc. (often shortened to Dolby Labs) is an American company founded by American Ray Dolby (1933-2013) in the United Kingdom in 1965, specializing in audio noise reduction and audio encoding/compression. Dolby licenses its technologies to consumer electronics manufacturers. Dolby Atmos started making its way into home theaters a few years ago. Now it’s pretty much standard in receivers with seven or more channels. This “object-based” format assigns audio “objects” to specific locations in your listening area to correspond to where they’d occur naturally in space. This adds a three-dimensional feel to the two-dimensional images on your screen. The overhead or up-firing speakers used in Atmos setups add a third number to the system configuration shorthand. For example, a five-channel Dolby Atmos system with two overhead speakers is a 5.1.2 system.
DTS (Dedicated to Sound), Inc. is an American company founded by Terry Beard in 1993, specializing in digital surround sound formats used for both commercial/theatrical and consumer grade applications. It was known as The Digital Experience until 1995. DTS licenses its technologies to consumer electronics manufacturers. In December 2016, DTS was acquired by Tessera, now called Xperi. Both of Dolby and DTS have very good sound effects, but which one is better? Let’s take a look closer look:
|Name||Dolby TrueHD||DTS-HD Master Audio|
|Features||lossless multi-channel audio codec||lossless multi-channel audio codec|
|Usage||mostly used in home-entertainment equipment||commonly used for surround-sound movie soundtracks on Blu-ray Disc|
|Channels supported||up to 8 discrete audio channels||up to 8/32 discrete audio channels|
|Highest bit rates||18Mbps||24.5Mbps|
|Range of HDMI||Rev1.3||Rev1.3|
|Range of HDMI||Yes||Yes|
|Diverse 7.1 program||No||Yes|
|Smart dynamic sound||Yes||No|
|Core technology||MLP Lossless||High Resolution Audio and DTS Digital Surround|
From technical facts listed above, it is difficult to separate the two in the sound experience, because both are committed to being mainstream High-definition applications provide lossless master-band audio effects.
But from the usage point of view, both of them are differentiated. Market differentiation will be their future trend. DTS-HD, same as the original DVD era, will be favored by audiophiles; and Dolby TrueHD, with home-based features, is likely to extend its applications, such as high-definition TV signals.
Part 2: Can Dolby and DTS apply to Blu-ray Disc?
Yes. In the Blu-ray Disc specification, Dolby TrueHD is an optional codec. Dolby TrueHD audiotracks may carry up to 8 discrete audio channels (7.1 surround) and 20 objects of 24-bit audio at 96 kHz or up to 6 channels (5.1 surround) at 192 kHz. The maximum encoded bitrate is 18 Mbit/s. Since Dolby TrueHD is an optional codec, a companion Dolby Digital bitstream (2.0 192Kbps or 5.1 448Kbps/640Kbps) must accompany the Dolby TrueHD bitstream on Blu-ray discs. Blu-ray Disc players consider this combination of two audio bitstreams as a single logical audio track, and a Blu-ray Disc player will automatically select the Dolby Digital or Dolby TrueHD bitstream depending on its decoding and/or audio bitstream output capabilities.
Dolby TrueHD sees its most popular usage as a high definition audio codec for Blu-ray Disc. Some early Blu-ray players did not support Dolby TrueHD coding, and in some cases, the player would resample it as standard Dolby Digital. All current Blu-ray players support Dolby TrueHD, along with the ability to upmix the source to a higher resolution format (Bitstream or LPCM), or downmix to a lower channel format depending on the player or equipment’s requirements. However, by late 2009 and early 2010, Dolby TrueHD had been steadily losing the lossless audio market share to rival DTS-HD Master Audio. This trend is inverse in case of 3D audio with Dolby Atmos encoded Dolby TrueHD releases outnumbering competing codecs.
