Hi, so far we were talking of the simpler routing scenarios. So let's shift to the next gear and discuss the more challenging setup's. In some cases we might have multiple zones, e.g a desktop PC were in one room and a stereo amplifier would be in another connected via S/PDIF. Say you want to do the usual stuff and see youtube videos in one room, while playing out music to the other room. Let's forget for a moment about that there is no profile with dual sink and focus on the possible routing issues. How would our media role based routing work? Both streams media role would be 'music' so it could not be used to select the sink. One option would be to add a property to the streams what would tell the 'zone'. The lack of property would default to a certain zone. That would be a natural thing from the application perspective but would break the currently proposed routing infrastructure. The other option would be to follow the bad example of profiles and have media roles like 'music' , 'music-in-zone2' etc. This thing would work with the proposed routing infrastructure but ... So any thoughts on this? We might need this for IVI scenarios, when different movies watched on the backseat of a car. -janos-
