Donc pour une branchement en HDMI vers un ampli mieux vaut laisser en PCM plutôt que reencoder avec perte. If you use an encoded format, then the PCM audio must be sent through the encoder. 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. This function provides access to audio comments, descriptive audio or other supplementary audio tracks. However, if you use either digital or optical coaxial outputs, Bitstream is the clear winner. For Dolby Digital the sampling frequency is 48 kHz, for DVD-Audio 96 kHz. I don't want the PS4 to decode the audio... thanks in advance . Linear Pulse Code Modulation = the uncompressed, linear PCM sound contained on the DVD. 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. Alors pcm ou bitsream sur PS4 pour netlifx ?

LPCM can transmit up to eight channels. 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. Bitstream is the Receiver decoding the audio steam. 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. For example, a satellite transponder transmits its digital TV programs as a bitstream. William Lemmerhirt Audioholic Warlord. Procedure. Digital optical and coaxial connections suffer from limited bandwidth and can’t transfer a fully-processed and decoded signal. It's exactly the same sound either way. Tv pcm ou bitstream. The choice depends on the quality of the individual devices – in this case on whether AV receivers or PS4s are better at decoding. As PCM, your signal is pure and usually in the highest quality. PS4 is connected to the TV via HDMI and the 4.1 Samsung Soundbar system is connected directly to the TV via Optical cable. 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). 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. 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;}.

In the DVD-Audio standard, the resolution is 24 bit. 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. 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. Bitstream audio means the receiver will decode all the sound, this is generally the easiest option for newer AVRs. 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. 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. 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 … 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. Supplemental audio is scaled down, which decreases quality. 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. ou celui fournit avec la ps4 est suffisant ? The Bitstream package is where the PCM data was sourced from. There is another factor to consider for this PCM vs Bitstream study: Secondary Audio. The player decodes the audio, without bandwidth concern, which is an issue for bitstream.
