Re: TV control API multiple module use case clarification

Hi Chris and Alex,
  Thanks for replying.

In our scenario
module A plays live content locally.
module B streams out live content over home network to other IP client
devices.
module C does recording.
There could be a second instance of module A that does PIP.
There could be multiple instances of module B depending on the number of IP
client devices that wants to play live content.

When a module requests for a tuner, TVManager should be able to grant or
deny depending on availability of tuners.

As Chris mentioned we would come up with possible API that can handle these
scenarios and update it in https://www.w3.org/2016/tvcontrol/

Thanks and regards,
Aginesh
