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. A DVD player outputs a bitstream at its audio-digital output. Chez moi, Helix sort en bitstream (digital) HDMI, mais je demande à mon Xbox X et PS4 Pro de sortir en PCM (HDMI). Surround, Objet 3D, Dolby Atmos, DTS:X, les Dolby Digital, Dolby Prologic et autre DTS-HD Master Audio. je viens d'aquerir un ampli yamaha plus un kit enceinte 7 .1 haut de gamme de la mort ...qui prend le son hd toussa toussa ... avec les entrées et sortie HDMI etc , bref. PCM (pulse code modulation) is the “raw” signal generated by the AD converter. 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. … 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. 2. - 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 is another factor to consider for this PCM vs Bitstream study: Secondary Audio. Après renseignement rapide, il y aurait une différence d'environ 3db sur la sortie PCM de PS3 vs un bitstream (voir PCM) sur une autre platine blu-ray pour les format DTS-MA voir aussi pour le Dolby-THD. There are also formats such as Dolby Digital or DTS where the signal is (source-)encoded. 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. You can play both Bitstream and PCM files on most DVD and Blu-Ray players. - 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. You have entered an incorrect email address! Il faut régler la sortie en bitstream pour que l'ampli fasse le boulot du decodage et t'affiche du DTS/DD 5.1 . If you combine the bitstream and secondary audio settings, the Blu-ray Disc player will “downstream” the surround sound formats, such as Dolby TrueHD or DTS-HD, to standard Dolby Digital or DTS so that both types of audio signals can be compressed into the same bitstream bandwidth. 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. 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). Effectivement je te conseille vivement de relier directement ta PS4 en HDMI à l'ampli plutôt que de passer par l'Optique : l'Optique n'a pas un débit suffisamment haut pour transiter le son "HD", l'HDMI le permet lui. Calling one "uncompressed" and the other "compressed" is grossly inaccurate. 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. Bitstream sends an encoded 5.1 signal over digital optical or coaxial. Tous droits réservés. NB: le nombre de canaux (2.1, 5.1, 7.1) n'indique pas nécessairement la qualité du son I personally use Bitstream so I can see on my Receiver it's being processed. 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. Here you can choose whether, for example, your Bluray player or your AV receiver should do the decoding work. 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. I've been reading up on PCM and bitstream and, as usual, you always find conflicting opinions on the Internet. However, if you use either digital or optical coaxial outputs, Bitstream is the clear winner. It's exactly the same sound either way. 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. I work in mastering and arranging bridges in existing songs and the arrangement and orchestration of chorus. D’après Dolby, l’Apple TV ne transmet pas les flux Dolby Digital Plus en passthrough HDMI / bitstream (mode de sortie AUTO). j'en avais entendu parler , mais on est en 2016 quand mm. This is my personal view and I do not have actual evidence retrieved. If you do not plan on doing this, and your receiver is not severely lacking in quality, go for Bitstream.eval(ez_write_tag([[250,250],'planethifi_com-netboard-1','ezslot_20',121,'0','0']));eval(ez_write_tag([[250,250],'planethifi_com-netboard-1','ezslot_21',121,'0','1'])); .netboard-1-multi-121{border:none !important;display:block !important;float:none;line-height:0px;margin-bottom:15px !important;margin-left:0px !important;margin-right:0px !important;margin-top:15px !important;min-height:250px;min-width:250px;text-align:center !important;}. Output audio via HDMI, and ensure that the "Audio Format (Priority)" is set to "Bitstream (Dolby)." PCM means the device itself decodes the sound and sends it. Le 24 novembre 2018 à 20:04:46 V12-biturbo a écrit : On most Blu-rays, there are audio elements in addition to the main soundtrack—specifically, the audio that accompanies PIP (picture-in-picture) commentaries and the sounds that onscreen buttons make when you click on them. during one second, the analog signal is sampled 44,100 times and converted into a digital value. If you use an encoded format, then the PCM audio must be sent through the encoder. 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. However not sure why but I think Sony ps4 has only a Dolby digital 5.1 bitstream option and Dts 5.1 bitstream option. 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. Ps4- Linear PCM Samsung Tv - Bitstream 4. I also write about AV topics, amplifiers, speakers and headphones. 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. 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. L'HDMI fournit avec la PS4 est suffisant ;)! In this update, we can certify that for the users, there is practically no noticeable difference in quality between PCM and Bitstream (1) (2). Linear PCM is the PS4 decoding the audio stream. What that actually is and which setting delivers the better sound is revealed here.

Ensuite pour le "problème des membranes" : tu dois confondre avec la période de rodage ;)! salut, j'ai mis en bitstream (DTS) et c'est mieux qu'avant ou j'avais mis PCM linéaire, pour un petit home cinéma Sony, c'est le bon choix ? Better quality access to additional audio tracks. 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. Compatibility with devices and supported frequencies are bigger factors to consider than sound and transmission when choosing between PCM and bitstream. Pulse Code Modulation, the coded data stream that occurs when analog audio information is converted into digital signals. The potential for greater audio quality and the flexibility to use coaxial outputs puts it ahead of PCM. The quantization (also called resolution) indicates how many different digital values a signal can be converted into. format HD: DOLBY-TRUE-HD, DTS-HDMA========sans pertes PCM is an algorithm for representing an analog wave digitally and has been around since the beginning of the 1900s. The player decodes the audio, without bandwidth concern, which is an issue for bitstream. What's better? And then there are some people that argue it's the other way around. This is not the only algorithm out there, there’s pulse width modulation, pulse position, pulse density, delta-sigma (which is used with DSD), and others but PCM is by far the standard (for audio). The Bitstream package is where the PCM data was sourced from. This is Planet HiFi. La version doublée anglaise fait son grand retour, et ré-enregistrée pour notre plus grand plaisir. 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. After all, it is designed for such cases. Provided it also supports the sound codec set on the PS4. We review all kinds of audio and video gear with complete independence from the manufacturer. * LA COMPRESSION PEUT SE FAIRE AVEC PLUS OU MOINS DE PERTES OU SANS AUCUNE.

Linear Pulse Code Modulation = the uncompressed, linear PCM sound contained on the DVD. Je peux également te donner quelques liens. Now i notice in the settings it gives me option for Linear PCM, and Bitstream (Direct), and Bitstream (Mixed). 1. On the other hand, most audio players only support the PCM format while transmitting sound. It takes up a lot of space but sounds very good. This allows 16.77 million different pieces of information to be displayed, which is 256 times the fine resolution of the standard CD. . FWIW, Atmos only works if bitstreaming. But I’m confused with PS4 Pro. In the PCM data stream of the CD, the sampling rate is 44.1 kHz, i.e. For Dolby Digital the sampling frequency is 48 kHz, for DVD-Audio 96 kHz. 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. Avertissement. So if the PCM signal is stereo, … More often than not, you will want Bitstream. The only options on the PS4 Pro are Linear PCM, Bitstream (Dolby), and Bitstream (DTS). Digital optical and coaxial connections suffer from limited bandwidth and can’t transfer a fully-processed and decoded signal. If you utilize Bitstream, then the AV receiver is performing the decode. LPCM can transmit up to eight channels. The receiving system on earth converts the bitstream into viewable TV programs. HDMI is easily the best option for output. 1 2 S. Stealth21 Audiophyte. PS4 is connected to the TV via HDMI and the 4.1 Samsung Soundbar system is connected directly to the TV via Optical cable.

If you plan to use the secondary audio feature, which provides access to audio commentaries, descriptive audio, and supplementary audio tracks, use PCM. 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. Si un format de sortie de votre système PS4™ n'est pas pris en charge par le périphérique connecté, les haut-parleurs risquent d'être endommagés. 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. Because the pure PCM signal can be recovered from the DTS-HD Master Audio track. My receiver can output most other … The picture above is for the settings of the Devialet Phantom Gold speakers that we reviewed here.
