Audio Symbols/Notations on DVBV Screen?

[mummum69]

Hi,

 

On DVBV screen I saw some different symbols and figures related with audio as in the pic below.

 

 

Would you please explain

 

1-)what it means , the symbols CO ( something like two intersected circles)? and figure 2/0 on item no 1 ?

2-) For the items 2 and 3, I can understand that AC3 2.0 and AC3 5.1( 2 way audio with AC3 format , or 5+1 way audio with AC3 format ??) But why their colours different from each other ( blue/red) ?

3-) Are there any other symbols or figures that i missed? If yes, what is their meanings?

 

Happy new year

two intersected circles = stereo (a very common symbol).

one circle = mono

different ac3 colors because 2.0 <> 5.1 so you have a visual feedback.
