Re: audio.basic schema question

[Ian Lowe]

Well, as the hooligan responsible for that one....

There is a general class of command based devices, where we are asking a
device or app to de something specific. The command= and extended= were
intended to be a general solution to the problem..

Given that a message which contains only an extended command will, by
definition, mean nothing to a device supporting only the basic command set
(or indeed a device using a different set of extended commands) I would
think the most compatible solution is

"command=none"

This is important to get right, as we will be needing something similar on
the OSD schema too: a "clear" command, as well as things like
"blink"...

the other thing to be resolved "once and for all" is whether it's
command=
and extended= or cmd= and ext=

Personally, my vote goes for the long versions.

Ian.

devices should use the "CMD=" tag to indicate a BASIC Command,
and "EXT=3D"
to indicate the Extended Commands for that device.
