Samsung SmartTV ovelray (news ticker) application

问题:

Is there any way the application can run as an overlay (ticker) over the DVB program (i.e. live broadcast)?

Currently the only working solution to display application as an overlay over part of the screen, we are aware of, is to start the application from TV SmartHub menu and display the overlay over the IP (usually HLS) stream.

See for example here (http://en.wikipedia.org/wiki/File:CNBC_Closing_Bell.jpg) the CNBS ticker. We would like to develop the application like this... to display additional info over the DVB (or other) broadcast.

Regards,

If you want to run application in a SmartHub and use TV source as a background of application this should help you:

For the method: http://www.samsungdforum.com/Guide/View/Developer_Documentation/Samsung_SmartTV_Developer_Documentation_2.5/API_Reference/JavaScript_APIs/Device_API/Window/SetSource

And for enumeration of sources: http://www.samsungdforum.com/Guide/View/Developer_Documentation/Samsung_SmartTV_Developer_Documentation_2.5/API_Reference/JavaScript_APIs/Device_API/Window/SetSource

It is only my guess because I have never needed to play TV in background - always used the PL_WINDOW_SOURCE_MEDIA as I'm working on Internet video streaming.

Remember that you need to have transparent background in your application CSS, because video in Samsung plays always under the background.

Hope It help!
