What Is Better Bitstream or Pcm?
PCM is not of a better quality than bitstreamed audio formats and the bitstreamed package is where the PCM data was sourced from. The only difference is which device is used to decode the compressed format to get the uncompressed PCM data. If you bitstream then it is the AV receiver that is doing this decoding.

In this way, what is difference between Bitstream and PCM?

For digital optical/coaxial connections, while the bitstream output option can send a standard Dolby Digital or DTS 5.1 surround sound signal to your receiver for further decoding, the PCM option will only send a two-channel signal.

Similarly, what is the best HDMI audio format? The highest quality possible for ARC is DTS and DD/DD+. If you are plugging your android box into your tv you should use passthrough for everything up to DTS, then send anything higher (i.e. the lossless) as 7.1 PCM and set your tv Digital Output Audio Format to DTS.

Also Know, what is audio bitstream?

Bitstream encoding is a core technology that is used in home theater audio. It provides a way to transfer data-heavy surround sound information between a source device and a home theater receiver or AV preamp/processor within a narrow bandwidth using a variety of connection options.

Is PCM surround sound?

PCM can carry surround sound, but it cannot do so over an optical cable—the optical cable can only carry stereo PCM (using TOSLINK, the home stereo standard). To send surround PCM, you'd need to use an HDMI cable (or alternatively displayport on a PC), which carries both the video and audio signal.

Should I use PCM or Dolby Digital?

Yes, PCM is uncompressed audio, whereas Dolby Digital is compressed, which compromises quality for space. Dolby TrueHD, on the other hand, is a lossless audio format, like a zip file, which is identical to PCM, in theory (I won't get into that debate). That's like asking if CD's sound better then MP3's.

What is PCM audio setting on TV?

Pulse-code modulation, abbreviated "PCM," is a form of digital signal that is used to represent analog data. Depending on the model of television you watch, switching the audio output to PCM may improve the sound quality of the television's speakers.
