Pcm is the more "pure" unencoded and bitstream is encoded. Some of them aren’t aware of what Bitstream and PCM are and why should they choose one over the other. Bitstream is the Receiver decoding the audio steam. The real issue is getting it through the optical cable. I personally use Bitstream so I can see on my Receiver it's being processed. So it depends on your setup and preference. In order for the PS4 to output Dolby Digital Plus and Dolby TrueHD formats we must first configure the PS4 to output audio via HDMI, and ensure that the "Audio Format (Priority)" is set to "Bitstream (Dolby)." Bitstream = PS4 sends encoded audio, receiver does the work. In the interactive title menu of a Blu-Ray disc, ensure a bitstream … PCM will decode the 7.1 or 5.1 core only and bypass the Atmos encoding. 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 … Again, that PCM signal will be downmixed to a 2.0 stereo signal. What's better? 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. When configuring an audio system for the first time, many individuals opt to compare PCM vs Bitstream. Calling one "uncompressed" and the other "compressed" is grossly inaccurate. For audio, if you connect a Blu-ray Disc player to a home theater receiver via HDMI, there are two main audio output settings available: Bitstream and PCM (which is also called LPCM). I stick with PCM for games (only because there's no option to keep the same format as the source) and use bitstream for Blu-Rays. Playback the disc and while it's playing, press the Falls das PCM-Signal also nur ein Stereosignal ist, kommt auch nur Stereo raus. Wer keinen Receiver hat und die PS4 direkt am Fernseher betreibt, fährt mit dieser Einstellung am besten. The PS4 has its own optical out port that you could hook straight to the soundbar. Dolby Digital: Das wohl gängigste Tonformat. Linear PCM: Bedeutet, dass die Konsole das unkomprimierte Signal an den Receiver schickt und der gibt es dann unverändert aus. In terms of sound quality, whether you set the Blu-ray Disc player's HDMI audio output PCM or bitstream doesn't matter. unless the audio track selected on the disc is a linear pcm track. I want my receiver handling lossless Dolby/DTS itself. As far as actual sound quality though, Linear PCM is perfectly fine. Now that the audio output of the PS4 is configured, we also need to make additional settings to ensure we get bitstream audio during video playback. PCM Setting 2. 4. the Digital Output Audio format can be change to Dolby Digital which is really amazing but for PS4 the Digital Output Audio format setting is locked at PCM so the only thing I could change in my Samsung Tv when connected to my ps4 is the HDMI input audio format Setting 1. Now i notice in the settings it gives me option for Linear PCM, and Bitstream (Direct), and Bitstream (Mixed). Dabei schickt die PS4 ein komprimiertes Signal an den AV-Receiver. Wenn das Signal ein 5.1-Signal ist, kommt auch 5.1-Sound raus. Bitstream but on the ps4 itself there's 3 options Linear PCM Interestingly, most of the individuals don’t have a clear idea of making a choice between PCM and Bitstream. Set the "Audio Format (Priority)" to "Bitstream (Dolby)". Linear PCM is the PS4 decoding the audio stream. PCM = PS4 decodes audio before sending it. Set the PS4 audio out port to optical, and then you can experiment with the PS4's PCM, Dolby, and DTS options without worrying about if the TV is causing issues or not. Bitstream re-encoded for Dolby/DTS will almost certainly do the same thing and give you just the core. No difference.
