donc le PCMlinear peut ressortir ayant plus ou moins perdu des éléments ou pas du tout. For audio, if you connect your Blu-ray Disc player to your home theater receiver via HDMI, there are two main audio output settings available: Bitstream and PCM (similar to LPCM, but not the same thing). Linear PCM or Bitstream(direct) for my PS4 Pro setup? ok je vais tester , mais pour les fps en ligne , j'vais perdre du temps de reponse ? D’après Dolby, l’Apple TV ne transmet pas les flux Dolby Digital Plus en passthrough HDMI / bitstream (mode de sortie AUTO). If you combine the bitstream and secondary audio settings, the Blu-ray Disc player will down-res surround formats, such as Dolby TrueHD or DTS-HD, to standard Dolby Digital or DTS to squeeze both types of audio signals into the same bitstream bandwidth. In this update, we can certify that for the users, there is practically no noticeable difference in quality between PCM and Bitstream (1) (2). Oui, j'ai mis Bitstream pour voir DTS HD-MSTR en gros. Pour faire simple : The ps4 (or xbox one) should be set to PCM audio in order to get the lowest latency audio from games. La plupart du temps, on privilégie Bitstream (DTS) au PCM car le PCM Multicanal n'est pas toujours pris en charge par les ampli, et également que beaucoup aiment quand le logo "DTS" s'éclaire sur leur ampli (oui oui, juste pour ça x)!). Btw to clarify, on my LG C9 for each HDMI input I have an option to select on LG C9 called “HDMI input audio format” in that option i have two choices, either Bitstream and PCM. It should also be noted that optical/coaxial digital cables cannot transfer Dolby Digital Plus, Dolby TrueHD or DTS-HD Master Audio as a bitstream or PCM – HDMI is required. Select "Audio … Bonjour, Étant newbee sur le sujet j'aurais une petite question à vous poser s'il vous plaît. For Dolby Digital the sampling frequency is 48 kHz, for DVD-Audio 96 kHz. Provided it also supports the sound codec set on the PS4. As a result, the receiver will display Dolby, Dolby TrueHD, DTS, DTS-HD Master Audio, Dolby Atmos, DTS:X, or another format on its front panel display depending on which type of bitstream signal is decoded. In terms of the actual audio quality, whether you have the audio output configured via HDMI to PCM or Bitstream is not important (11).eval(ez_write_tag([[250,250],'planethifi_com-medrectangle-4','ezslot_3',107,'0','0'])); In terms of the actual audio quality, whether you have the audio output configured via HDMI to PCM or Bitstream is not important. The advantage of this is that the audio track can be compressed and stored on your Bluray, but you still get the highest quality in the end. PCM gets the sound directly from your console without having to go through a home theater to get it right. There are a number of factors that should go into your choice, including the quality of your Blu-ray player and audio receiver. This involves access to secondary soundtracks, such as audio commentary, descriptive audio, or other supplementary audio tracks. … [1-son crée en studios]=====>[2-blurayPs3/Ps4]====>[3-ConsolePs3/Ps4]====>[4-AmpliAV]=====>[5-Haut-parleurs] en Bitstream le flux brute contenue sur le disque est envoyé au pré-ampli via le HDMI, et c'est l'ampli qui décode en PCM c'est le lecteur qui décode avant de l'envoyer au pré-ampli dans le fond ça ne change rien, ça reste du numérique dans tout les cas donc pas de différence de qualité, sauf si il y a des limites au HDMI et dans ce cas souvent le lecteur s'adapte, ce qui … Message édité le 28 janvier 2016 à 17:33:36 par, Message édité le 29 janvier 2016 à 14:53:31 par, Message édité le 29 janvier 2016 à 15:31:51 par, Message édité le 29 janvier 2016 à 16:22:50 par, Message édité le 14 novembre 2017 à 01:49:50 par, NieR Replicant Ver 1.22 : Le casting anglais se manifeste. It takes up a lot of space but sounds very good. Does the PS4 give you a choice between DTS and Dolby Digital for in game audio or something? The sound settings menu on PS4 has an option called "sound output (priority)" or something like that. PCM is therefore merely a specification that controls which device is used for decoding. Digital optical and coaxial connections suffer from limited bandwidth and can’t transfer a fully-processed and decoded signal. If you plan to use the secondary audio feature, which provides access to audio commentaries, descriptive audio, and supplementary audio tracks, use PCM. The reason for this is that a digital optical or coaxial digital cable does not have sufficient bandwidth capacity to transfer a decoded, uncompressed, fully surround audio signal as an HDMI connection can. Voilà la différence entre les 2. Here are several similarities to consider when choosing which is the best option for you: However, there is another factor to consider as to which setting may be best for you to decide in this discussion PCM vs Bitstream. PCM transmits a two-channel signal over digital optical or coaxial. me reste plus qu'as tester bf pour voir si je perd pas trop de temps sur mes duels ... et essayer les blue ray 3d etc ... une dernière question , le vendeur m'as conseiller de pousser un peu le son de temps en temps , parce que sinon les membranes des baffles durciraient et que la sonore se degraderai légèrement, qu'est ce que vous en penser ? This means that an additional setting option that may be available on your Blu-ray player is “BD-Secondary Audio”. With this option, your home theater receiver will display “PCM” or “LPCM” on the front panel display. That data file is not very useful unless you know the parameters used by the PCM encoding so we use headers and containers for streaming/storage.eval(ez_write_tag([[250,250],'planethifi_com-leader-4','ezslot_14',122,'0','0'])); Wav, AIFF, FLAC, Ogg, mp3, DD, DTS, etc are all containers, some happen to be more than just that such as FLAC, MPEG, DD, DTS (and others) which are also a compression algorithm(some lossy, some lossless) and/or encoding scheme. Le DTS est meilleur que le Dolby, privilégie donc le DTS. Je demande à mes consoles de traiter le son, alors que Helix je demande à mon ampli de le faire. La version doublée anglaise fait son grand retour, et ré-enregistrée pour notre plus grand plaisir. If access to these audio features is important to you then keep your Blu-ray player configured with the PCM audio output option that would be the best choice for you. Donc pour une branchement en HDMI vers un ampli mieux vaut laisser en PCM plutôt que reencoder avec perte. For audio, if you connect a device (Blu-ray Disc player, Ultra HD Blu-ray disc players or other similar devices) to a home theater receiver via HDMI, there are two main audio output settings available: Bitstream vsPCM (which is similar, but not equal, to LPCM). I don't want the PS4 to decode the audio... thanks in advance . This means that the signal is not additionally source-coded by, for example, DTS or Dolby Digital, and is therefore not converted. From the Settings menu, select "Sound and Screen". If you select Bitstream as the HDMI audio output setting for a Blu-ray player, the player bypasses its internal Dolby and DTS audio decoders and sends the undecoded signal to your HDMI-connected home theater receiver. This is Planet HiFi. However, in this case, whereas the Bitstream output option can send a standard Dolby Digital or DTS 5.1 surround sound signal to your receiver for later decoding, the PCM option will only send a two-channel signal. I … There are also formats such as Dolby Digital or DTS where the signal is (source-)encoded. On my old PS3 I chose "Bitstream", I liked it because it showed in the input and output signal on the UMC-1 (Dolby in and Dolby out for a DVD for example). Avertissement. Since PCM is an algorithm, compressed/noncompressed doesn’t make any sense from a technical standpoint, it takes an input and gives you an output and doesn’t care what the data is. As a result, your home theater receiver will not have to do any additional audio decoding before the audio is sent through the amplifier and speaker section. I work in mastering and arranging bridges in existing songs and the arrangement and orchestration of chorus. Re: BITSTREAM ou PCM pour écoute de qualité ? However, in this case, while the Bitstream output option can send a Dolby Digital or DTS 5.1 surround sound signal to your receiver for later decoding, the PCM option will only send a 2-channel signal.eval(ez_write_tag([[250,250],'planethifi_com-leader-3','ezslot_13',118,'0','0'])); The reason for this is that the optical digital cable or coaxial cable does not have sufficient bandwidth capacity to transfer a decoded, uncompressed, full surround sound signal, as the HDMI connection can. Passe ton son en HDMI et pas en optique tu seras moins réduit, enfin je veux dire par là que le HDMI est au dessus de l'optique niveau possibilité etc. Bitstream sends an encoded 5.1 signal over digital optical or coaxial. This is the question that all owners of a home cinema system with an AV receiver and console like PS4 are asking themselves: PCM vs Bitstream? Linear PCM is the PS4 decoding the audio stream. Alternatively, you can always switch from PCM to Bitstream at any time by going to the appropriate settings menu.eval(ez_write_tag([[250,250],'planethifi_com-mobile-leaderboard-2','ezslot_16',120,'0','0'])); While audio signals are produced differently in both cases, there is no audible difference between Bitstream and PCM files. PCM itself comes in a couple of flavors, regular PCM where quantization levels is a function of amplitude and LPCM where quantization levels are uniformly linear (hence linear pulse code modulation). MP2 is also not the same as MP3 even if they are the “same technology”. For digital optical and coaxial connections, while the bitstream output option can send a standard Dolby Digital or DTS 5.1 surround sound signal to a receiver for decoding, the PCM option sends a two-channel signal. We are not praising and adoring audio and video manufacturers, we do not just paste a bunch of useless statistics and we avoid utilizing nerdy needless technical jargon unless we explain to you what does it mean. There is another factor to consider for this PCM vs Bitstream study: Secondary Audio. Our articles are about televisions, soundbars, projectors, speakers, home theater systems, amplifiers, and headphones.  Writing about audio and video is the most fun activity that we can have. Chez moi, Helix sort en bitstream (digital) HDMI, mais je demande à mon Xbox X et PS4 Pro de sortir en PCM (HDMI). Message par doombledor » 22 janvier 2016, 16:17 Merci à vous 2 de vos conseils c' est ce que je vais faire comme vous dites laisser le PANA en bitstream et l' ampli fera ce qu il faut en décodage audio car les harman kardon dans leur rapport qualité prix sont trés bons musicalement parlant si je ne me trompe pas . PCM is an algorithm for representing an analog wave digitally and has been around since the beginning of the 1900s. This allows 16.77 million different pieces of information to be displayed, which is 256 times the fine resolution of the standard CD. Bitstream and PCM are capable of producing the same audio quality, and the only difference is how your setup decodes the compressed file. during one second, the analog signal is sampled 44,100 times and converted into a digital value. It’s cool you can choose 5.1 or 7.1 on the Switch, and cool that there’s a PS5 option to make it send the right thing too. Could be wrong on ps4 stuff since I don't have my ps4 in media room, I just use a Regular 3D Sony bluray player " which I keep in bitstream to get my lossless uncompressed … This is because their native audio format is PCM and they can mix multichannel PCM with no delay. 16-bit word width is standard for the CD. With this option, the home theater receiver will display the PCM term on its front panel display. The difference between PCM and Bitstream is in regards to the device utilized for decoding the compressed format to retrieve the uncompressed PCM data. Without speakers, the DTS and Dolby option will sound looser than PCM losing quality in the volume and smaller sounds.eval(ez_write_tag([[250,250],'planethifi_com-box-4','ezslot_1',108,'0','0'])); When it comes to setting up an audio system, in the discussion PCM vs Bitstream, people often confuse LPCM and PCM with Bitstream. DOLBY DIGITAL===================plus de pertes PCM is best suited to those who do not have an AV receiver and output the sound via the TV boxes. Because the pure PCM signal can be recovered from the DTS-HD Master Audio track. * LA COMPRESSION PEUT SE FAIRE AVEC PLUS OU MOINS DE PERTES OU SANS AUCUNE. For games PCM is best assuming the Bose supports PCM 5.1 or PCM 7.1 audio which is the highest quality audio source on PS4. Then, it sends the decoded audio signal in an uncompressed form to the home theater receiver. NB: le nombre de canaux (2.1, 5.1, 7.1) n'indique pas nécessairement la qualité du son - PCM Linéaire : la console décode le son et l'envoie à l'ampli, l'ampli s'occupe donc juste de l'amplifier. je laisse le topic ouvert , pour les prochains freres au cas ou ... Perso avec mon ampli Onkyo je suis en PCM Minéaire et tout se passe bien sans pb vu que le son n'est pas compressé. That means you should check the compatibility of your device when choosing between the two. Alors pcm ou bitsream sur PS4 pour netlifx ? If access to these audio programs is important to you, keeping your Blu-ray player set to PCM will provide the best quality result. PCM (pulse code modulation) is the “raw” signal generated by the AD converter. Others still do not know which option to choose or which is best for them. The choices in that menu are: PCM, bitstream (Dolby) and bitstream (DTS). 1 2 S. Stealth21 Audiophyte. A sequence of digital data consisting of a string of bits. - Bitstream (Dolby et/ou DTS) : la console envoie le son de manière brute à l'ampli et c'est l'ampli qui décode le son. After you determine the audio settings you want to use to transfer audio from your Blu-ray player to the rest of your home theater system, you must also decide what type of connections to use. So after you can determine which audio settings you want to use to transfer audio from your Blu-ray Disc player to the rest of your home theater system, you must also decide what type of connections you need to use. Supplemental audio is scaled down, which decreases quality. I just got a PS4, I checked the audio output settings and I have the options of Linear PCM, Bitstream Dolby and Bitstream DTS. In general, however, the AV receiver is usually the better choice. As a result, in this case, the AV receiver will display on its main display the tags Dolby, Dolby TrueHD, DTS, DTS-HD Master Audio, Dolby Atmos, DTS:X, etc… depending on what type of Bitstream signal is being decoded.eval(ez_write_tag([[250,250],'planethifi_com-leader-2','ezslot_12',113,'0','0'])); It should be noted that the Dolby Atmos and DTS:X surround formats are only available from a Blu-Ray player via the Bitstream option. Copyright © 1997-2021 Webedia. You must first configure your PS4 to: Output bitstream audio for games and video playback. Procedure. The receiving system on earth converts the bitstream into viewable TV programs. 46ES7000 - SR7009 - HCS628+S622 - JBL ES250PW - PS3 - PS4 - WiiU - X360 - XONE. If PCM is selected, the PS4 takes over the audio decoding of the sound material and passes it to the AV receiver, which usually outputs it to the speakers unchanged with the specified number of channels. After all, it is designed for such cases. Because this is the standard (for audio), pretty much everything uses it AVR, pre/pro, stereo receiver, sound cards/onboard sound, pretty much everything that deals with converting digital to audio (and audio to digital) uses PCM at the bottom of the chain. j'en avais entendu parler , mais on est en 2016 quand mm. You have the option to choose which type of setting to use (PCM vs Bitstream), and as mentioned above, each setting should produce the same audio quality, taking into account the exceptions of Dolby Atmos and DTS:X. If you have your player connected to the AV receiver via HDMI, there are 2 main audio output settings available: Bitstream and PCM (9). With this option, the home theater receiver displays the term PCM or LPCM on its front panel display. LPCM can be stored in different quantization or resolutions (16 bit, 20 bit or 24 bit) and in different sampling rates or sampling frequencies (48 kHz or 96 kHz).eval(ez_write_tag([[580,400],'planethifi_com-netboard-2','ezslot_22',123,'0','0'])); Normal PCM, as in the audio CD sector, transmits up to two channels. This also calls for PCM: If you want to output HD sound formats such as Dolby True HD or DTS HD, but the AV receiver does not support them.eval(ez_write_tag([[300,250],'planethifi_com-narrow-sky-2','ezslot_19',125,'0','0'])); Save my name, email, and website in this browser for the next time I comment. You can play both Bitstream and PCM files on most DVD and Blu-Ray players. 1. ou celui fournit avec la ps4 est suffisant ? This function provides access to audio comments, descriptive audio or other supplementary audio tracks. Then, if the user decides to use Bitstream as the HDMI audio output setting for their Blu-ray player, the player will bypass its own internal Dolby and DTS audio decoders and send the signal without decoding to their HDMI-connected home theater receiver. Output audio via HDMI, and ensure that the "Audio Format (Priority)" is set to "Bitstream (Dolby)." Pulse Code Modulation, the coded data stream that occurs when analog audio information is converted into digital signals. The quantization (also called resolution) indicates how many different digital values a signal can be converted into. If you use either the coaxial or optical digital connection option of your Blu-ray player to your home theater receiver (very useful if your AV receiver does not have HDMI connections), you can also select the PCM vs Bitstream output options for those connections. Bonjour à toi ! salut je profite de ce topic pour poser une question. Normal que la différence ne soit pas flagrante... : l'HDMI comme l'Optique permet de transiter du DTS, donc pas de différence notable. FS#9112 - Passthrough => PCM ou BITSTREAM Bonjour, Avant tout, voici des explications sur le fonctionnement du “Passtrought HDMI”, se déclinant soit en format PCM soit BITSTREAM : - PCM (Passthrough désactivé sur freeplayer) ⇒ le signal multicanal (dolby digital, dolby digital +, DTS, DTS HD MA ...) est décodé en interne par le freeplayer puis est envoyé à l’ampli par le … (1-linearPCM)=(compression)=(2-pistes de son en bitsteam)==[3- activer(a) ou non(b) le decodage par la console]==(la sortie optique ne supporte pas les formats HD et ne supporte que le PCM linear stereo, pas plus de 2 cannaux; l'HDMI supporte TOUT)===[4- (a)l'ampliAV récupéré du pcmLinear et l'envoie aux baffles vous ne verrez pas le nom d'un format bitstream s'afficher dessus (b)l'ampliAV récupère du bitstream et le décode/décompresse lui même, le format du bitsteam s'affiche sur l'ampliAV -NB: s'ils ont été activé les réglages d'equalizer de l'ampliAV s'appliquent toujours: movie, music, jazz, concert..etc..]===[5-les enceintes reçoivent les signaux venant du LPCM produit par l'ampliAV et les retranscrivent en ondes que vous entendez], autre note importante, depuis la ps3 et aussi sur la ps4 sony incorpore un outils de RE-ENCODAGE AUDIO dans ses consoles, on peut le constater quand on est sur ps3 dans des appli video du psn , sur ps4 par exemple si vous avez un équipement audio pouvant jouer du son surround (dolbydigital, dts, dts-hdma...) et si vous reglez la console sur Bitstream-dolbydigital et que via un support USB ou votre ordinateur en reseau local vous entrez dans le media center et vous lancez une video ayant une piste audio stereo (2canneaux), la ps4 fera sortir en audio 6 canaux (5.1) en dolby digital car l'ampli l'affichera ainsi, donc le son stereo est arrivé et son LPCM 2.0 a été convertit en LPCM 5.1 et ré-encodé en dolbydigital 5.1 puis evoyé à l'équipement audio. When you play any of these formats, they all are converted to PCM data for the DAC to use. PS4 is connected to the TV via HDMI and the 4.1 Samsung Soundbar system is connected directly to the TV via Optical cable. One is decoded at the source(bd player, stb etc), and one is decoded at the AVR. This is my personal view and I do not have actual evidence retrieved. However, if you use either digital or optical coaxial outputs, Bitstream is the clear winner. I work as an audio engineer and audio technician. It requires a high-quality receiver to achieve better results. Compatibility with devices and supported frequencies are bigger factors to consider than sound and transmission when choosing between PCM and bitstream. NB: la différence de qualité à l'écoute entre le son produit après décodage d'un format de compression sans pertes, avec plus ou avec moins de pertes, DEPENDS AUSSI D'AUTRES FACTEURS comme de les hauts-parleurs, la qualité du traitement de l'ampli(equaliseur) et évidement du son source. Please do not lump PCM and LPCM together, even though they are both the same technology. PS4 Audio question regarding Linear PCM vs. Bitstream Dolby/DTS So up until tonight, my launch PS4 Pro's audio setting had been set to Bitstream (Dolby), since it sounded the best to me. format SD: DTS============================moins de pertes Là où tu verras une différence (si ton matos est de très bonne qualité), c'est sur les Blu Ray avec notamment le format DTS HD Master Audio que seul l'HDMI permet de transiter. More often than not, you will want Bitstream. In the PCM data stream of the CD, the sampling rate is 44.1 kHz, i.e. It's exactly the same sound either way. Although the above discussion focuses on PCM vs Bitstream with respect to Blu-ray Disc players, the same information may also apply to Ultra HD Blu-ray Disc players.eval(ez_write_tag([[250,250],'planethifi_com-mobile-leaderboard-1','ezslot_15',119,'0','0'])); While Bitstream and PCM are very different, these two configurations are very similar when applied in audio production. Well, it is just a data file you can call it PCM data file but when it is just referred to as PCM misunderstandings happen (and the thing you have to understand is that going from analog to digital is not 1 to 1, going from digital to analog is though so in a broad general sense PCM is a lossy compression algorithm itself). Ce paramètre n'est disponible que sur certains systèmes PS4™. parce que y'as un peu plus d'1 kw la quand mm ... Bon je viens de passer sur un forum un peu plus spécialisé , et effectivement faut faire peter les watts de temps a autre ,surtout quand on as une grosse config ... perso j'y aurai pas cru .... 3 personne différentes me l'ont confirmer. I did some searching and most people say to use Linear PCM, otherwise the PS4 … For me, PCM is for those who do not use speakers or play with headphones. In this case, your home theater receiver will recognize the signal as Dolby Digital standard and decode it properly.eval(ez_write_tag([[250,250],'planethifi_com-large-mobile-banner-1','ezslot_10',114,'0','0'])); Therefore, using this setting the user combines the primary high-resolution audio signal (Dolby TrueHD or DTS-HD Master Audio) with the secondary audio signal – however, if you use this setting, the Blu-ray player will lower the resolution from Dolby TrueHD or DTS-HD to Dolby Digital standard or DTS in order to be able to input both types of audio signals in the same bitstream. Jan 5, 2020 #2 They’ll sound the same. With this setting, the AV receiver will do all the audio decoding of the incoming signal. Marquer comme nouveau; S'abonner au fil RSS; Surligner; Imprimer; Envoyer à un ami; Signaler un … If you use an encoded format, then the PCM audio must be sent through the encoder. Je peux également te donner quelques liens. In terms of actual audio quality, it does not matter if the HDMI audio output from your Blu-ray Disc player is set to PCM or Bitstream. I personally use Bitstream so I can see on my Receiver it's being processed. If you set your Blu-ray Disc player to output audio as PCM, the player will perform audio decoding of all Dolby/Dolby TrueHD and DTS/DTS-HD Master Audio related soundtracks internally and send the decoded audio signal in uncompressed form to the home theater receiver. FWIW, Atmos only works if bitstreaming. Yes, I know, you see chips that include DD/DTS decoding and they do that, but it is still a conversion to PCM data first before converting to analog. However not sure why but I think Sony ps4 has only a Dolby digital 5.1 bitstream option and Dts 5.1 bitstream option. Now i notice in the settings it gives me option for Linear PCM, and Bitstream (Direct), and Bitstream (Mixed). quelle sont les meilleurs paramètre pour moi ? If you set the player to send Bitstream, you will not hear this secondary audio, but if you set it to send PCM, the secondary audio is mixed with the main soundtrack so you can hear it. Je peux me tromper mais il me semble que le terme bitstream est enfaîte faux concernant les options de la PS4, en gros en PCM c'est bien la console qui décode et sans compression via HDMI ensuite, alors que les options bitstream DTS et Dolby sont enfaîte ce que l'on appelle du DTS Interractive/Connect et du Dolby Digital Live, à savoir une compression à la volée de l'audio dans ces formats pour pouvoir notamment passé du 5.1 par du S/PDIF (optique et coaxial) et donc qui dit compression qui permet de qualité. If PCM is selected, the PS4 takes over the audio decoding of the sound material and passes it to the AV receiver, which usually outputs it to the speakers unchanged with the specified number of channels. 1. PS4- Bitstream DTS Samsung Tv - PCM 3. Surround, Objet 3D, Dolby Atmos, DTS:X, les Dolby Digital, Dolby Prologic et autre DTS-HD Master Audio. The setting is also applicable for the Phantom Silver.eval(ez_write_tag([[300,250],'planethifi_com-large-leaderboard-2','ezslot_9',110,'0','0'])); To continue with this PCM vs Bitstream discussion, let´s see a practical setting in PCM. je viens d'essayer et effectivement sa envoie du paté! Playback the disc and while it's playing, press the However, there are also lossless compression methods such as DTS-HD Master Audio or Dolby TrueHD. NieR Replicant fait peau neuve, et non seulement au niveau des graphismes ou du gameplay. I am Bob. Is there any way to bitstream HD audio from the PS4? There is currently no Blu-ray player that can decode these formats internally for PCM and pass them on to the Home Theater receiver, which in part finishes this PCM vs Bitstream confrontation. Note: If your receiver takes over the decoding, the corresponding logo usually appears on the display. We review all kinds of audio and video gear with complete independence from the manufacturer. In Planet HiFi I test gear during a couple of days and write a review. As PCM, your signal is pure and usually in the highest quality. Linear Pulse Code Modulation = the uncompressed, linear PCM sound contained on the DVD. It s available also in 720p devices. You have entered an incorrect email address! No difference. le son passe en optique pour l'instant .... quelqu'un peut m'expliquer vite fait la différence entre le pcm linéaire et le bitstream ? But like a lot of things, it takes on new meanings though it is not necessarily correct in the strictest sense, in this instance many people also include the digital output as just “PCM” also. The only options on the PS4 Pro are Linear PCM, Bitstream (Dolby), and Bitstream (DTS). rappel: ces format une fois décompressés produisent du linear PCM HDMI is easily the best option for output. The potential for greater audio quality and the flexibility to use coaxial outputs puts it ahead of PCM. - BITSTEAM: divers formats dans lequel est compressé le PCMLINEAR pour le faire tenir le son aisément sur des support (CD, DVD, BRD) ou le faire passer aisément par certains media/cable (optique/spdif). There are several recording modes with different resolutions (8, 12, 16, 20 and 24 bit) and different sampling rates (32kHz, 44.1kHz, 48kHz, 88.2kHz, and 96kHz) for LPCM. This means that if you set the audio output of your Blu-ray player to PCM, the player will decode the audio of all Dolby/Dolby TrueHD and DTS/DTS-HD Master Audio formats – from the internally related soundtracks and send the audio signal in an uncompressed form to the AV receiver in your home theater.eval(ez_write_tag([[300,250],'planethifi_com-leader-1','ezslot_7',111,'0','0'])); As a result, the AV receiver will not have to perform any additional audio decoding before it is sent to the amplifier section and speakers. sa dénature pas le son en dolby ? As a result, the home theater receiver will not perform additional audio decoding before the audio is sent through the amplifier section and the speakers. In this case, the home theater receiver recognizes the signal as standard Dolby Digital and decodes appropriately. For Blu-rays you can choose to output in PCM or bitstream Dolby/DTS TrueHD/DTS-MA passing them to the sound system, there really isn't much of a difference but not all sound systems may support PCM 5.1/7.1 so in that case you would select bitstream. So if the PCM signal is stereo, … LPCM can transmit up to eight channels. So if the PCM signal is stereo, the only stereo will be output. tout ceci est souvent tenu à l'ecart des reglages audio fait pour la lecture des disques bluray. These formats are transmitted in so-called bitstreams. The Bitstream package is where the PCM data was sourced from. If you utilize Bitstream, then the AV receiver is performing the decode. Si tu as un bon Ampli/décodeur met en bistream sinon laisse en PCM. So for my Apple TV 4K, I selected bitstream on my lg c9 as Dolby Atmos is not compatible on PCM. Bitstream is the Receiver decoding the audio steam. Alors pcm ou bitsream sur PS4 pour netlifx ?
