DTS, Inc. (originalmente Digital Theater Systems ) es una empresa estadounidense que fabrica tecnologías de audio multicanal para películas y videos. Con sede en Calabasas, California , la empresa introdujo su tecnología DTS en 1993 como competidor de Dolby Laboratories , incorporando DTS en la película Jurassic Park (1993). [3] [4] [5] El producto DTS se utiliza en formatos de sonido envolvente para aplicaciones comerciales / teatrales y de consumo. Se conocía como The Digital Experience hasta 1995. DTS otorga licencias de sus tecnologías a la electrónica de consumo. fabricantes.

La marca DTS fue adquirida por Tessera Holding Corporation en diciembre de 2016, luego Tessera pasó a llamarse Xperi Corporation.

Historia [ editar ]

DTS fue fundado por Terry Beard, un ingeniero de audio y graduado de Caltech . Beard, hablando con un amigo de un amigo, pudo ponerse en contacto con Steven Spielberg para audicionar una remasterización de la película Encuentros cercanos del tercer tipo de Spielberg mezclada en DTS. Luego, Spielberg seleccionó el sonido DTS para su próxima película, Jurassic Park (1993) y con el respaldo de Universal y su entonces matriz, Matsushita Electric , más de 1,000 teatros en los Estados Unidos adoptaron el sistema DTS. [6]

El trabajo en el nuevo formato de audio comenzó en 1991, cuatro años después de que Dolby Laboratories comenzara a trabajar en su nuevo códec , Dolby Digital .

La versión básica y más común del formato es un sistema de 5.1 canales, similar a una configuración Dolby Digital, que codifica el audio como cinco canales primarios (rango completo) más un canal LFE ( efectos de baja frecuencia ) especial para el subwoofer. .

Los codificadores y decodificadores admiten numerosas combinaciones de canales, y las bandas sonoras estéreo, de cuatro canales y de cuatro canales + LFE se han lanzado comercialmente en DVD, CD y Laserdisc.

Otras variantes de DTS más nuevas también están disponibles actualmente, incluidas versiones que admiten hasta siete canales de audio principales más un canal LFE (DTS-ES). Estas variantes se basan generalmente en la filosofía de núcleo y extensión de DTS, en la que un flujo de datos DTS central se aumenta con un flujo de extensión que incluye los datos adicionales necesarios para la nueva variante en uso. El flujo central puede ser decodificado por cualquier decodificador DTS, incluso si no comprende la nueva variante. Un decodificador que comprende la nueva variante decodifica el flujo central y luego lo modifica de acuerdo con las instrucciones contenidas en el flujo de extensión. Este método permite la compatibilidad con versiones anteriores.

Los principales competidores de DTS en audio teatral multicanal son Dolby Digital y SDDS , aunque solo Dolby Digital y DTS se utilizan en DVD y se implementan en hardware de cine en casa.

Uno de los inversores iniciales de DTS Inc. fue el director de cine Steven Spielberg , quien sintió que los formatos de sonido teatral hasta la fundación de la compañía ya no eran de vanguardia y, como resultado, ya no eran óptimos para su uso en proyectos donde la calidad del sonido la reproducción era de suma importancia. Spielberg debutó en el formato con su producción de 1993 de Jurassic Park , que se produjo poco menos de un año completo después del debut teatral oficial de Dolby Digital ( Batman Returns ). Además, Jurassic Park también se convirtió en el primer lanzamiento de video casero que contiene sonido DTS cuando se lanzó en LaserDisc en enero de 1997, dos años después del primer lanzamiento de video casero Dolby Digital ( Clear and Present Danger en Laserdisc), que debutó en enero de 1995.

En 2008, la división de cine se desintegró para formar DTS Digital Cinema . En 2009, Beaufort International Group Plc adquirió DTS Digital Cinema. y se hizo conocido como Datasat Digital Entertainment .

SRS Labs [ editar ]

En 2012, DTS adquirió el negocio de SRS Labs (Sound Retrieval System), una tecnología de procesamiento de audio 3D psicoacústico, que incluye más de 1.000 patentes y marcas comerciales de audio.

Manzanita Systems [ editar ]

En 2014, DTS adquirió Manzanita Systems, [7] un proveedor de software MPEG para televisión digital, VOD e inserción de anuncios digitales. [8]

Phorus [ editar ]

Phorus, una subsidiaria de DTS, Inc., es un grupo de tecnología con sede en Los Ángeles dedicado al audio inalámbrico para dispositivos conectados. [9]

HD Radio (iBiquity) [ editar ]

El 2 de septiembre de 2015, iBiquity anunció que estaba siendo comprado por DTS por US $ 172 millones, uniendo la tecnología de transmisión de radio digital HD Radio de iBiquity con los sistemas de sonido envolvente de audio digital de DTS. [10]

Uso teatral [ editar ]

En el uso teatral, se crea una imagen óptica de un código de tiempo patentado de 24 bits en la película. Un lector de LED escanea los datos del código de tiempo de la película y los envía al procesador DTS, utilizando el código de tiempo para sincronizar la imagen proyectada con el audio de la banda sonora DTS. El audio DTS multicanal se graba en formato comprimido en un CD-ROM estándar.medios a una tasa de bits de 882 kbit / s. La compresión de audio utilizada en el sistema DTS teatral (que es muy diferente y no tiene nada que ver con el formato DTS Digital Surround basado en Coherent Acoustics en el hogar) es el sistema APT-X100. A diferencia de la versión doméstica de DTS o cualquier versión de Dolby Digital, el sistema APT-X100 tiene una relación de compresión de 4: 1. La reducción de datos se logra mediante codificación de subbanda con predicción lineal y cuantificación adaptativa. El procesador DTS teatral actúa como un mecanismo de transporte, ya que sostiene y lee los discos de audio. Cuando se lanzó el formato DTS, utilizó uno o dos discos con unidades posteriores que contenían tres discos, lo que permitió que un solo procesador DTS manejara bandas sonoras de películas de dos discos junto con un tercer disco para tráileres teatrales.El código de tiempo DTS en la impresión de 35 mm identifica el título de la película que coincide con los CD-ROM DTS individuales, lo que garantiza que la película no se pueda reproducir con el disco incorrecto. Cada CD-ROM DTS contiene un programa DOS que el procesador usa para reproducir la banda sonora, lo que permite agregar fácilmente mejoras al sistema o correcciones de errores. A diferencia de Dolby Digital y SDDS, o la versión doméstica de DTS, el sistema DTS teatral solo lleva 5 canales discretos en los CD-ROM. La pista del subwoofer .1 LFE se mezcla en los canales envolventes discretos del disco y se recupera mediante filtros de paso bajo en el cine.A diferencia de Dolby Digital y SDDS, o la versión doméstica de DTS, el sistema DTS teatral solo lleva 5 canales discretos en los CD-ROM.

Tecnologías DTS [ editar ]

DTS Digital Surround [ editar ]

A nivel de consumidor, DTS es la abreviatura más utilizada para el códec DTS Coherent Acoustics (DCA) , transportable a través de S / PDIF y parte de las especificaciones de LaserDisc , DVD y Blu-ray . Este sistema es la versión para el consumidor del estándar DTS, que utiliza un códec similar sin necesidad de medios de CD-ROM DTS separados. Al igual que los reproductores de CD estándar, los reproductores de DVD y Blu-ray Disc no pueden decodificar el audio de los CD de audio DTS.

DTS is related to the aptX audio coding format, and it is based on the adaptive differential pulse-code modulation (ADPCM) audio data compression algorithm.[11][12] In contrast, Dolby Digital (AC-3) is based on the modified discrete cosine transform (MDCT) compression algorithm.[13][14]

Both music and movie DVDs allow delivery of DTS audio signal, but DTS was not part of the original DVD specification, so early DVD players do not recognize DTS audio tracks at all. The DVD specification was revised[when?] to allow optional inclusion of DTS audio tracks. The DVD title must carry one or more primary audio tracks in AC-3 or LPCM format (in Europe, MPEG-1 Audio Layer II is also an allowed primary track format). The DTS audio track, if present, can be selected by the user. Subsequent DVD players now decode DTS natively or pass it through to an external decoder. Nearly all standalone receivers and many integrated DVD player/receivers can decode DTS.

A small number of Laserdiscs carry DTS soundtracks. The NTSC Laserdisc format allows for either analog audio only or both analog and digital audio tracks. Laserdiscs encoded with DTS sound[15] replace the LPCM digital audio track with the DTS soundtrack. This soundtrack is output via digital coaxial or optical audio outputs and requires an external decoder to process the bitstream.

For PC playback, many software players support the decoding of DTS. The VideoLAN project has created a decoding module for DTS called libdca (formerly libdts), which is the first open source implementation of DTS.[16]

Sony's PlayStation 3 and Microsoft's Xbox 360 are capable of DTS decoding and output via TOSLINK or HDMI as LPCM. However, HDMI output on the Xbox 360 is only found on the "Elite" model and newer models available since mid-2007, with the release of the Falcon motherboard revision. Also, the Xbox 360 cannot decode DTS from DTS audio CDs. PlayStation 3 consoles can bitstream DTS over HDMI, but cannot decode audio from DTS audio CDs. The newer "slim" models are able to bitstream DTS-HD MA as well, but also cannot decode audio from DTS CDs.

Comparison with Dolby Digital[edit]

DTS and Dolby Digital (AC-3), DTS's chief competitor in the cinema theatre and home theatre markets, are often compared because of their similarity in product goals, though Dolby believed that the surround channels should be diffused[clarification needed] and DTS said they should be directional.[citation needed] In theatrical installations, AC-3 audio is placed between sprocket holes on the 35 mm film itself, leaving the audio content susceptible to physical damage from film wear and mishandling. DTS audio is stored on a separate set of CD-ROM media, with greater storage capacity that affords the potential to deliver better audio fidelity and is not subject to the usual wear and damage suffered by the film print during the normal course of the movie's theatrical screening. Disregarding the separate CD-ROM assembly as a potential point of failure, the DTS audiopath is comparatively impervious to film degradation, unless the film-printed timecode is completely destroyed.

In the consumer (home theater) market, AC-3 and DTS are close in terms of audio performance. When the DTS audio track is encoded at its highest legal bitrate (1509.75 kbit/s), technical experts rank DTS as perceptually transparent for most audio program material (i.e., indistinguishable to the uncoded source in a double blind test).[citation needed] Dolby claims its competing AC-3 codec achieves similar transparency at its highest coded bitrate (640 kbit/s). However, in program material available to home consumers (DVD, broadcast, and subscription digital TV), neither AC-3 nor DTS typically run at their highest allowed bitrate. DVD and broadcast (ATSC) HDTV cap AC-3 bitrate at 448 kbit/s. But even at that rate, consumer audio gear already enjoys better audio performance than theatrical (35 mm movie) installations, which are limited to even lower bitrates. When DTS audio was introduced to the DVD specification, a few studios authored DTS tracks on some DVDs at the full bitrate (1509.75 kbit/s). Most later DVD titles that offered DTS tracks were encoded at 754.5 kbit/s (about half the rate of 1536kbit/s). At this reduced rate, DTS no longer retains audio transparency. This was done to make room for more audio tracks and content to reduce costs of spreading extra material on multiple discs.

AC-3 and DTS are sometimes judged by their encoded bitrates.[citation needed] Dolby Digital 5.1 can compress the same data to less, taking up minimal space. Conversely, DTS proponents claim that the extra bits give higher fidelity and more dynamic range, providing a richer and more lifelike sound. But no conclusion can be drawn from their respective bitrates, as each codec relies on different coding tools and syntax to compress audio.

In addition to the standard 5.1-channel DTS Surround codec, the company has several other technologies in its product range designed to compete with similar systems from Dolby Labs. Those which conceptually extend DTS (to add more channels and/or more accurate sound reproduction) are implemented as extensions to a core DTS Coherent Acoustics data stream.[17] The core stream is compatible with DTS decoders which do not support the extension(s); the extension(s) provide the additional data required to implement the additional functionality.

DTS 70 mm[edit]

This is a process designed specifically for playback in motion picture theaters equipped with 70mm projection and 6-track surround sound. The 70 mm DTS prints do not have 6-track magnetic striping, so there is no analog backup should the digital sound fail. The time code track on the film is many times wider than the 35mm version, since it can occupy the real estate formerly taken up by a magnetic track. Theaters with 70 mm DTS frequently install two time code readers for greater reliability.

The gradual disappearance of 70 mm as a common exhibition format has led to DTS-70 being reserved for niche engagements of 70 mm revivals and restorations. Dolby Digital has not been adapted to the 70 mm format.

DTS-ES[edit]

DTS-ES (DTS Extended Surround) includes two variants, DTS-ES Discrete 6.1, and DTS-ES Matrix 5.1, depending on how the sound was originally mastered and stored.[18] Both variants are implemented in ways which are compatible with DTS decoders which do not include support for DTS-ES.

DTS-ES Matrix provides 5.1 discrete channels, with a matrixed center-surround audio channel. DTS processors that are compatible with the ES codec look for and recognize "flags" built into the audio coding and "unfold" the rear-center sound from data that would otherwise be sent to rear surround speakers. DTS decoders which do not understand ES process the sound as if it were standard 5.1 and the matrixed audio for the center surround channel is output equally from the two surround speakers (very much as a sound intended to be in the center of the sound field in a stereo recording is played equally by the left and right speakers). This is notated as DTS-ES 5.1.

DTS-ES Discrete provides 6.1 discrete channels, with a discretely recorded (non-matrixed) center-surround channel; in home theater systems with a 7.1 configuration, the two rear-center speakers play in mono. To maintain compatibility with DTS decoders which do not support DTS-ES, the center-surround channel is also matrixed into the left and right surround channels, so that the rear center channel's sound is still present when played in 5.1 on a non-ES system; an ES decoder removes the matrixed audio from these two channels when playing back DTS-ES Discrete soundtracks. DTS-ES Discrete is sometimes notated as DTS-ES 6.1. Only a few DVD titles have been released with DTS-ES Discrete.

In contrast, Dolby's competing EX codec, which also boasts a center rear channel, can only handle matrixed data and does not support a discrete sixth channel; it is most directly comparable to DTS-ES Matrix.

Note: The center-rear/surround channel is encoded and decoded in exactly the same way as the center-front. The center-surround channel can be decoded using any surround sound processor by feeding the left and right surround signals to the processor inputs. The left-Center-Right surround is produced. This will work for a "center-surround" reproduction, whether the source material is explicitly encoded, as in DTS-ES, or hidden as the ambience in any 5.1 sources, including DTS-ES 5.1 and Dolby 5.1.

DTS 96/24[edit]

DTS 96/24 allows the delivery of 5.1 channels of 24-bit, 96 kHz audio and high quality video on the DVD-Video format. Prior to the development of DTS 96/24, it was only possible to deliver two channels of 24-bit, 96 kHz audio on DVD Video. DTS 96/24 can also be placed in the video zone on DVD-Audio discs, making these discs playable on all DTS-compatible DVD players. DTS 96/24 is implemented as a core DTS stream plus an extension containing the deltas to enable 96/24 sound reproduction.

DTS-HD High Resolution Audio[edit]

DTS-HD High Resolution Audio, along with DTS-HD Master Audio, comprise the DTS-HD extension to the original DTS audio format. It delivers up to 7.1 channels of sound at a 96 kHz sampling frequency and 24-bit depth resolution. DTS-HD High Resolution Audio is selected as an optional surround sound format for Blu-ray Disc, with constant bit rates up to 6.0 Mbit/s and 3.0 Mbit/s, respectively. It is intended to be an alternative for DTS-HD Master Audio where disc space may not allow it. DTS-HD High Resolution Audio is implemented as a core DTS stream plus an extension containing the two additional channels plus details to enable 96/24 sound reproduction.

DTS-HD Master Audio[edit]

DTS-HD Master Audio, previously known as DTS++,[19] is the second of two DTS-HD audio formats.[20] It supports a virtually unlimited number of surround sound channels, can deliver audio quality at bit rates extending from lossless (24-bit, 192 kHz) down to DTS Digital Surround and, like Neo, downmix to 5.1 or 2.1 systems.

DTS-HD Master Audio is selected as an optional surround sound format for Blu-ray, where it has been limited to a maximum of 8 discrete channels. DTS-HD MA supports variable bit rates up to 24.5 Mbit/s, with up to 6 channels encoded at up to 192 kHz or 8 channels and nine objects encoded at 96 kHz/24 bit. If more than two channels are used, a "channel remapping" function allows for remixing the soundtrack to compensate for a different channel layout in the playback system compared to the original mix.

All Blu-ray players can decode the DTS "core" resolution soundtrack at 1.5 Mbit/s, however, as DTS-HD Master Audio is also implemented as a standard DTS core plus extensions, but cannot decode audio from DTS audio CDs. DTS-HD Master Audio and Dolby TrueHD are the only technologies that deliver compressed lossless surround sound for these new disc formats, ensuring the highest quality audio performance available in the new standards. (DTS Coherent Acoustics' coding system was selected as mandatory audio technology for Blu-ray Discs.[21]

DTS:X[edit]

For each speaker, DTS:X allows the "location" (direction from the listener) of "objects" (audio tracks) to be specified as polar coordinates. The audio processor is then responsible for dynamically rendering sound output depending on the number and position of speakers available. Dolby Atmos uses a similar technique,[22][23] although the speaker layout employed by cinema DTS:X is the sum of Dolby Atmos and Auro-3D. The layout showcased at AMC Burbank theatre number 8 has a standard eight channel base layer, a five channel height layer on top of the base layer (on the front and side walls) and three rows of speakers on the ceiling. The surround arrays are bass managed by woofers suspended from the ceiling.[24]

DTS Neo:6[edit]

DTS Neo:6, like Dolby's Pro Logic IIx system, reconstructs 2.1, 5.1, 6.1, or 7.1 sources to 3.1, 4.1, 5.1, 6.1, and 7.1 channel systems. A 7.1 system's 2 rear speakers are mono. Neo:6 is a multi-band decoder, unlike Dolby Pro Logic II's broadband logic steering, meaning that the decoder can enhance more than one predominant signal at a time — provided each predominant signal lies in a different frequency band than the others. The number of bands steered varies in each Neo:6 implementation, with the first decoders steering in 12 separate bands and later units steering up to 19.

DTS Neo:X[edit]

DTS Neo:X reconstructs 2.1, 5.1, 6.1, or 7.1 sources to 11.1 front height and width channel systems. Dolby's Pro Logic IIz's system adds only front height channels to the 7.1 configuration. Neo:X also matrix downmixes 11.1 sources to 5.1 or 7.1 channel systems.

DTS Neural:X[edit]

DTS Neural:X usually comes on systems that also have DTS:X, and is an upmixing technique for upmixing or remapping legacy bitstreams and PCM content to virtually any speaker layout, in which the sound can come from anywhere around the listener, including above.[25]

DTS Virtual:X[edit]

DTS Virtual:X creates "phantom" surround and/or height speakers using psychoacoustic processing of existing soundtracks (including, if needed, the creation of height channels) to allow systems with a reduced number of physical speakers (such as TV soundbars) to provide a more "immersive" experience.[26]

DTS Surround Sensation[edit]

DTS Surround Sensation: Previously known as DTS Virtual. It allows a virtual 5.1 surround sound to be heard through a standard pair of headphones.[27]

DTS Headphone:X[edit]

DTS Headphone:X is metadata which can be encoded on top of a 2-channel lossy DTS bitstream that reproduces 12 channels of binaural surround sound using any pair of stereo headphones.[28] The head related transfer function is developed by DTS and includes compensation for room cues such as reflection and delay by mapping the acoustic characteristic of the original mixing studio, or other professional audio lab as a reference.[29]

DTS Connect[edit]

DTS Connect is a blanket name for a two-part system used on the computer platform only, in order to convert PC audio into the DTS format, transported via a single S/PDIF cable.[30] The two components of the system are DTS Interactive and DTS Neo:PC. It is found on various CMedia soundcards and onboard audio with Realtek ALC883DTS/ALC889A/ALC888DD-GR/ALC892-DTS-CG and SoundMAX AD1988 chips, as well as several cards based on the X-Fi chipset, such as the SoundBlaster Titanium series and Auzentech's X-Fi Forte, X-Fi Prelude, X-Fi Home Theater HD and X-Fi Bravura cards.

  • DTS Interactive: This is a real-time DTS stream encoder. On the PC, it takes multichannel audio and converts it into a 1.5 Mbit/s DTS stream for output. Because it uses the original DTS codec to transmit audio, fidelity is limited to 5.1 channel at 48 kHz, 24bit. More than 5.1 channels, a higher sampling frequency or data rate are not supported, due to the lack of support for DTS variants such as DTS 96/24. It can also be found on some standalone devices (e.g., Surround Encoder). Nearly a dozen titles on the PlayStation 2 feature the "DTS Interactive" real-time stream encoder, such as Grand Theft Auto: Vice City and Terminator 3: Rise of the Machines.
  • DTS Neo:PC: This is a technology based on the DTS Neo:6 matrix surround technology, which transforms any stereo content (MP3, WMA, CD Audio, or games) into a simulated 7.1-channel surround sound experience. The 7.1-channel surround sound is output as a DTS stream for output via a S/PDIF cable port.

DTS Play-Fi[edit]

Play-Fi is a wireless protocol for multiroom audio based on the existing 802.11 specification (b/g/n). It emerged in late 2012 as an Android streaming protocol, with iOS support added in September 2013, and Windows support later, including audio/video sync.[31] The first Play-Fi speaker was the Phorus PS1, made by DTS subsidiary Phorus.[32]

Unlike competitors such as Sonos or SoundTouch from Bose, Play-Fi is an open standard[citation needed] and has been adopted by a wide range of brands including Anthem, Arcam, Audiolab, Definitive Technology, Hewlett-Packard, Integra, Klipsch, MartinLogan, McIntosh, Onkyo, Paradigm, Pioneer, Polk Audio, Rotel, Sonus Faber, Soundcast and Wren. The Play-Fi app supports streaming from the user's device, DLNA servers,[33] via AirPlay[34] and from online streaming services including Spotify, Pandora Radio, Amazon Prime Music, iHeart Radio, Rhapsody, SiriusXM, Tidal, Qobuz, KKBox, QQ Music, and Juke.[35] DTS Play-Fi also introduced a Play-Fi enabled wireless speaker with Amazon Alexa Voice Services built-in under the Onkyo, Phorus, and Pioneer brands in September 2017.[36]

Other Play-Fi capabilities include:

  • grouping speakers for individual simultaneous playback of the same source and so that their volume can be controlled simultaneously[37]
  • grouping speakers in stereo[38] or surround[39] configurations
  • creating zones for playing different audio streams to different groups of speakers[40]
  • streaming line-in input to a speaker group[41]
  • streaming of arbitrary audio output on computers running Windows[31] or Linux with PulseAudio (albeit with a delay[42] and only to individual speakers, as opposed to groups, zones, or stereo configurations[43])
  • streaming the left and right surround channels of a broadcast or movie to 2 wireless Play-Fi speakers to be used as surround channels with a Play-Fi enabled sound bar.[44]
  • Ability to stream and decode high resolution audio (up to 96 kHz / 24-bit).[45]

Play-Fi doesn't support Google Cast, rebroadcasting Bluetooth input to more than one speaker,[46] or audio streaming in sync with video on non-Windows systems.[47]
