the basic difference is that there is 1 input line for the demux whereas a decoder has no input lines

You can see them online at various websites.

File format option check boxes are suitably checked, then the operation is run.

Audio or Video can be selectively disabled, or recoded using a different codec, or resampled for a new bits per second rate, or height & width. This way elemental audio or video stream files result. VirtualDub can also demux AVI files. Tmpgenc v2.5x or higher works with mpg-1 and mpg-2 files and can demux those videos to elemental streams as well as combine elemental streams back into mpeg videos. Some digital video editing suites can take a video and demux it into its parts. Google search >demux OR decode OR demultiplex audio video<

The differences between these two circuits is subtle, as far as I can tell. A demux simply selects an output line, nothing more. It's a glorified switch. A decoder takes n inputs, and uses those inputs to determine which of the 2^n output lines is high. This is the difference, I think. A decoder is designed to simply keep one line high. A demux is designed to set one output equal to the input (whether it be high, low, or a changing signal).

Multiplexing is the combination of several signals on one carrier or medium.

Demultiplexing is the extraction of each of the original signals.

You can't have just one or the other, they are both necessary in the communication process.

So the concept of one having an advantage over the other is senseless.
