Most DVD players only support 48 kHz/16-bit capability. Only more high-end players have built-in 96 kHz/24-bit capabilities. |

== Standard sampling resolutions and rates ==
Common sample resolutions for LPCM are 8, 16, 20 or 24 bits per [[sample (signal)|sample]].
While two channels (stereo) is the most common format, some can support up to 8 audio channels (7.1 surround).
Common sampling frequencies are 48 [[hertz|kHz]] as used with [[DVD|DVD]] format videos, or 44.1 kHz as used in [[Compact disc|compact discs]]. Sampling frequencies of 96 kHz or 192 kHz can be used on some newer equipment, with the higher value equating to 6.144 megabits per second per audio channel.

It seems to me that the 6.144 mbps figure is arrived at by multiplying 192 kHz and 32 bits.
This gets you 6144000 bits per second. It is not clear that 32 bit samples were used in this calculation, especially since it isn't listed in the list of common sample resolutions.
Furthermore, 6144000 bps Is equal to 5.859375 mbps, not 6.144 mbps.
It is unfortunate that the example used here is so similar to the max bitrate for PCM tracks on a DVD - 6144 kbps.
