In terms of sound quality, whether you set the Blu-ray Disc player's HDMI audio output PCM or bitstream doesn't matter. However, here is what happens when you choose either setting. Although the below discussion focuses on bitstream vs. PCM with regards to Blu-ray Disc players, the same information can also be applied to Ultra HD Blu-ray Disc players Jeg forstår det sånn at PCM kun gjengir lyd i stereo, mens Bitstream gir digital lyd, f.eks. DTS? Grunnen til at jeg spør er fordi jeg har valget mellom PCM og Bitstream på setup til DVD-spilleren. Jeg har LG RH 7500 som DVD-spiller, kombinert med en Denon AV-1804 (kjøpte ny fra HiFi-klubben i fj..

Dette er en bra ting, da det ville være lite hensiktsmessig å komprimere lyden i PS4en for så å dekomprimere den i forsterkeren
PCM = source component decodes the signal Bitstream = AVR decodes the signal The one and only difference is that when using PCM, the pretty lights on your AVR won't light up. The exception to this is Atmos. Atmos must be Bitstreamed as there are no source components (that I know of) that can decode it . I guess my question is what are the better settings? I also have a DVD player hooked up on passthrough to the TV via a soundbar. 0 Likes Reply. All forum topics Bitstream and PCM are industry-standard methods of transferring audio from a transmitter or player to a receiver or speaker. Blu-ray players have various output settings depending on how they connect to the AV receiver. If the connection is HDMI,.
Bitstream is basically the raw undecoded data being sent to the receiver for it to decode. PCM means that the PS3 is converting to PCM and sending it to the receiver which pretty much all receivers understand My speakers say they support DTS and Dolby Digital. I couldn't get consistent sound out of them using my HDMI devices and my TV (so sound coming from the TV through optical) regardless of whether I picked Linear PCM (default) or Auto on the TV so I took the TV out off the equation by connecting the PS4 directly to the speakers, setting it to bitstream so the speakers use the speakers the. The game setting of Bitstream or PCM is independent of blu rays. You can have games using PCM and when you have a blu ray in go to audio options and change that to bitstream. Only have to do it once. User Info: jaygood. jaygood 6 years ago #10. Well linear PCM forces 7.1 on my receiver Pcm is the more pure unencoded and bitstream is encoded. The real issue is getting it through the optical cable. I'm 90% sure linear pcm is too high of bandwidth for a multi channel signal in optical, so you need to use the encoded Dolby/dts bitstream to transmit and then unpack at the sound bar
Bitstream unprocessed. That means the player will send out the audio signal exactly as it is, and leave it up to your receiver to do all of the decoding. PCM will decode the 7.1 or 5.1 core only and bypass the Atmos encoding. Bitstream re-encoded for Dolby/DTS will almost certainly do the same thing and give you just the core My AVR (Marantz 8002) tells me when the source is sending PCM or it's internally decoding a codec and exactly what it's decoding. I guess that might be why sometimes I see sound coming as pcm instead of bitstream from the BD player. I have a little PCM led on the AVR that tells me and sometimes it's activated while navigating discs.. Hi, i have a samsung ks9000 and i have 2 options on the hdmi audi format which is pcm and bitsream and they both play in 5.1. Can someone please tell me which is the recommemed setting for the playbar and my 5.1 set up as i cant tell the difference. The audio format is set to dolby digital. Thank
For eksempel er PCM- og Hi-Res-lyd eksempler på lyd som bruker bitstreams for å overføre digitale lydsignaler. Hvordan Bitstream brukes i hjemmekino I hjemmekinoapplikasjoner er en bitstrøm mer definert som en metode for overføring av kodede lydsignaler fra bestemte surroundlydformater fra en kilde til en kompatibel hjemmekino-mottaker eller AV-forsterker / prosessor. Please excuse my ignorance but could someone explain the following: In the sound menu of my Toshiba TV, these is a setting for Bitstream or PCM. I know what PCM is, but what is the difference between Bitstrem and PCM, and what setting should I be using Thanks for your anticipated repl Bitstream unprocessed. That means the player will send out the audio signal exactly as it is, and leave it up to your receiver to do all of the decoding. PCM will decode the 7.1 or 5.1 core only and bypass the Atmos encoding. Bitstream re-encoded for Dolby/DTS will almost certainly do the same thing and give you just the core That's just a difference between bitstream and multi-ch pcm; bitstream has your avr doing the decoding, and having your xbox do the decoding for export as multi-ch pcm. No real right or wrong and as Pogre says, you could drive yourself insane trying to figure out if one has an advantage You may get more dsp choices in your avr by bitstreaming, tho I've been looking into audio formats used for surround sound and by far, it seems that PCM is a much better format than any bitstream format such as Dolby and DTS. But when looking at different AV amplifiers and receivers, many support Dolby TrueHD and DTS HD and not PCM
In addition to the above method, a DVD Blu-ray or Ultra HD Disc player may also provide the capability to decode the bitstream from a disc internally to the PCM format. Instead of the receiver decoding the bitstream coming from a player, the player may send a decoded signal in PCM form digitally to a home theater receiver via HDMI or in analog form through multichannel analog audio connections Hi, apologies I'm not particularly well versed in regards to stereo uncompressed and bitstream. My setup is Xbox one x > LG 4k TV > Yamaha YAS-207 Soundbar. All via HDMI (with arc). My audio settings are: HDMI bitstream and optical bitstream, then DTS. This works fine when playing games and watching Sky on Sky app
Linear PCM = uncompressed surround sound. Bitstream (Dolby) = compressed surround sound. Bitstream (DTS) = compressed surround sound. basically you want Linear PCM, Dolby/DTS exist for compatibility reasons with certain audio hardware that can't handle the Uncompressed audio. level 2 . From what I understand, if you pick uncompressed, the Xbox decodes the signal into PCM and sends it to your receiver or TV. Bitstream on the other hand, sends the signal untouched to your receiver to process rather than letting the Xbox handle it PCM can only deliver up to 7.1 channels, ergo the 3D audio part will be lost, if you let the Vero transcode the audio stream to PCM before passing it to your AVR. If you want to benefit from 3D audio, you'll probably have to live with the time your AVR needs to detect the passthrough audio stream after every playback initialization or after resuming playbac Bitstream - will send the raw digital audio without processing out of the DVD player so your receiver can process PCM - the player will convert everything to and output as 2 channel PCM So if you want your receiver to process DD and DTS multichannel tracks then you must set the player to Bitstream This PCM/Bitstream option doesn't effect the.
The bitstream setting is used when you want to pass the digital audio bitstream to your reciever for decoding. PCM will use either the decoder in your DVD player (if it has a built in DD/DTS decoder) or will downconvert to 2 channel if that is the output you are using The default setting of Bitstream on my LG TV causes issues with hearing dialogue on my rogers ingite box, so i switched it to PCM and the sound is better but i have been reading that this is a lower quality sound option. is it better to directly connect my devices to the sound bar and disable arc/cec? if i keep it at bitstream, why is the dialogue sound very low PCM Bitstream (Audiophile) Bitstream (Re-encode) PCM output means that the Blu-ray Disc player itself either passes along the uncompressed multichannel PCM stream that is recorded on the disc, or decodes the high-resolution audio tracks, depending on which soundtrack you select in the disc's menu (or the player defaults to), and sends the resulting uncompressed digital audio signal to a.
The sound settings menu on PS4 has an option called sound output (priority) or something like that. The choices in that menu are: PCM, bitstream (Dolby) and bitstream (DTS). My receiver can output most other formats too, but the PS4 only lists Dolby Digital and DTS as options I received an email from nVidia today to state that my graphics card (nVidia GForce GTX 1060 6GB) only outputs sound in PCM. I've asked nVidia and AMD if any of their GPUs allow audio to be output in bitstream. I'd happily move to AMD if the RX 580 / Vega 56 did allow bitstream or look at a sound card that enabled the same PCM Audio vs Bitstream Audio For Blu-ray Disc Player Audio Settings When it comes to setting up an audio system, people often confuse PCM with bitstream. Others don't even know which option to choose or why it's the best for them PCM and Bitstream are the differences Under PCM (pulse code modulation) refers to the raw, from the AD Converter generated Signal. The Signal is coded, in addition, by, for example, DTS or Dolby Digital, the source, and thus converted
For audio, a bitstream can be used to convert sound into digital bits and then that information is transferred from a source device to a receiver, and, eventually, to your ears. PCM and Hi-Res audio are examples of digital audio formats that utilize bitstreams Which is best, PCM or bitstream from a Blu-ray player to the A/V receiver? I have reviewed many posts on various forums, but I have not found a definitive answer. I have an Onkyo TX-SR608 AVR and an LG Blu-ray player capable of decoding DTS-HD Master Audio and Dolby TrueHD lossless audio. I view Blu-ray discs and regular DVDs about 50/50; certainly Blu-ray when available I believe that PCM is when a 2 channel digital audio(i.e. CD type audio stream) is fed through the digital connection to the receiver. Bitstream is multi-channel audio(be it DTS or DD)
The receiver said PCM on the screen and in the check signal area. I reviewed the player again. In the player menu was something odd. The choices under SPDIF were bitstream, PCM, stereo PCM. The choices under HDMI are PCM, and stereo PCM. So it seems I can not bitstream out the HDMI, I need to use an optical cable for bitstream Bitstream or pcm? by seanmwaple Nov 19, 2016 5:47PM PST. I just got a new samsung un65ku6300 4k tv I have my samsung 5.1 j5500 setup with my xbox one. Should i have hdmi audio. DVD & Home Theater Gear - Bitstream vs. linear pcm? - Got PS3. Have an Onkyo 605 receiver that can do DTS-MA and Dolby TrueHD. Which is the route to go? Let the PS3 process the sound and pass it along as pcm or bitstream it and let receiver process it? I don't see any real discernible different in terms of soun
I am a noob at this and recently learned that that to hear Dolby or DTS over HDMI in their raw form your output device (blu ray player)must be set to bitstream. But what ive noticed if settings are on pcm you can get up to a 7.1 channels. Ive listened to both and don't notice much of a difference. So which is better I have a Pioneer VSX-21 receiver with a PS3 and Sony 560 hooked up through HDMI. For the PS3 I use PCM and the 560 Bitstream. The Bitstreamed audio is about 10 db louder than the PCM audio. I also have a Toshiba HD-35 where I can choose to bitstream or send the audio through PCM. Again the bitstreamed audio is louder by about 10db Hi, I have just got into Blu ray and have a question regarding the two audio formats! PCM vs Bitstream, wich does what and wich one is used with what, i am confused about it all and thought id seek some answers on here. the reason i ask is due to my player asking me in the BD setting to pick one,.. I tried to do some research about Bitstream and Linear PCM audio, but after reading some articles my understanding is still pretty vague... I'm also wondering which one is better... I use optical. biTStream. biTStream is a set of C headers allowing a simpler access to binary structures such as specified by MPEG, DVB, IETF, SMPTE, IEEE, SCTE, etc. . biTStream vs. libdvbpsi. libdvbpsi converts binary structures to C structures. Lists are implemented with chained lists of C structures
