I think we do have to take into account that scanning means different things in different circumstances. For non-mobile devices, channel scanning is something that typically happens once when the device is initially set up, and then happens very infrequently after that - usually only when the network operator changes the channel lineup. For mobile devices, this happens more frequently but I'm not sure how frequently. In my mind, I see the channel scanning operation as something that is initiated by the end user or automatically by the platform, rather than by a web app. The result of a channel scanning operation is that: 1. The list of available channels may change 2. The attributes of an individual channel (related to tuning information) may change A web app may care about (1) but I'm not sure that will really care about (2). The only case where that would make a difference to the app is when the tuning parameters change for a channel that is currently being presented, and I would expect the device to automatically handle that situation. In that case, it may be enough for the TVManager or TVSource to dispatch an event indicating that a channel list has been updated and for all other aspects of the scanning functionality to be handled by the user agent. -- GitHub Notification of comment by stevem-tw Please view or discuss this issue at https://github.com/w3c/tvcontrol-api/issues/7#issuecomment-259371872 using your GitHub account
