For those of you who don't know what HbbTV is:

Providers can provide HTML content tailored for TV by transmitting the according URL inside the AIT of the DVB stream.

The TV (several models of Sony, etc) or DVB receiver (eg Vantage VT1) then displays the URL on screen upon pressing the red button on the remote control.
It is possible to include video content in such pages or display the live TV picture (either in the background or resized in a window).

So the providers may provide stuff like EPG, enhanced Videotext, VoD offers, etc. 

>From a technical point of view the following steps would be necessary to have this functionality in MythTV:

* read the AIT from the DVB stream and check for URLs
* upon red-button key-event, display the URL (with Live TV picture either in background or resized in the HTML-page. Maybe no live pic at all, only audio. Resized display should be comparable to PIP or Live-View in EPG???).
* Key-Events should then be handled by the displayed HTML-page instead of Fullscreen-TV (eg cursor keys, OK, numbers, ...)

Is anybody already working on this?

How complicated do you estimate the development to be? Is MythTV's modularity sophisticated enough to make it possible right now or will changes to the architecture be necessary?

Thanks for your answers in advance!
