Should i use pcm or dolby digital

Blu-ray reviews: 1. I run 5. X3 and especially Live Free or Die Hard are pretty much demo material on my system. Blu-ray collection: 6. I am just getting my HD setup as well and have a related question. Member since: Nov Trading Score: 8. Originally Posted by skrill. I need to add my ignorance to this thread.

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. While Bitstream and PCM are very different, these two configurations are very similar when applied in audio production.

Here are several similarities to consider when choosing which is the best option for you:. However, there is another factor to consider as to which setting may be best for you to decide in this discussion PCM vs Bitstream.

This involves access to secondary soundtracks, such as audio commentary, descriptive audio, or other supplementary audio tracks. 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. Alternatively, you can always switch from PCM to Bitstream at any time by going to the appropriate settings menu. While audio signals are produced differently in both cases, there is no audible difference between Bitstream and PCM files.

However, the Bitstream files are encoded to give you a surround sound experience when used with a compatible media player. On the other hand, most audio players only support the PCM format while transmitting sound. That means you should check the compatibility of your device when choosing between the two. HDMI is easily the best option for output. However, if you use either digital or optical coaxial outputs, Bitstream is the clear winner.

There are a number of factors that should go into your choice, including the quality of your Blu-ray player and audio receiver. More often than not, you will want Bitstream. The potential for greater audio quality and the flexibility to use coaxial outputs puts it ahead of PCM. The only situation where PCM comes out on top is when using secondary audio streams.

If you do not plan on doing this, and your receiver is not severely lacking in quality, go for Bitstream. PCM is an algorithm for representing an analog wave digitally and has been around since the beginning of the s. PCM itself comes in a couple of flavors, regular PCM where quantization levels is a function of amplitude and LPCM where quantization levels are uniformly linear hence linear pulse code modulation.

Well, it is just a data file you can call it PCM data file but when it is just referred to as PCM misunderstandings happen and the thing you have to understand is that going from analog to digital is not 1 to 1, going from digital to analog is though so in a broad general sense PCM is a lossy compression algorithm itself. Pulse Code Modulation, the coded data stream that occurs when analog audio information is converted into digital signals. The quantization also called resolution indicates how many different digital values a signal can be converted into.

This allows 65, different audio information to be represented. In the DVD-Audio standard, the resolution is 24 bit. This allows LPCM can be stored in different quantization or resolutions 16 bit, 20 bit or 24 bit and in different sampling rates or sampling frequencies 48 kHz or 96 kHz.

Should I use PCM or auto? Does Samsung TV have 3. Where is sound output on Samsung TV? How do I connect an audio jack to my Samsung TV? Can you connect headphones to a Samsung TV?

Do all TVs have an audio out? Why does my Samsung TV say audio out? How do I connect external speakers to my Samsung TV? These items include a cable box, satellite receiver, set box, game console, DVD players, Blu-ray players, or anything else you can connect.

The output is what the devices receive from your television. If you want to hear audio, the signal sends it to the speakers for your listening pleasure. You can also use the output to send audio to soundbars, Surround Sound speakers , or headphones. That means you should select PCM or Dolby Digital in your menu options based on what your setup offers.

The output format you choose when selecting the audio format for your television depends on the equipment you have connected to the television.

You may need to create different settings for a home theater system than you would for high-quality headphones. Are you not connecting anything to your television? You might experience audio loss, volume problems, or additional issues if you choose the alternative environment. You can only choose the options on some televisions that are currently available with your input and output.

As a general rule, you should only use the PCM option for your audio if your sound system experiences higher setting problems.
