Hello,
i see your setup, it's fairly standard.
you just need a proper AIT section, did you update the PSI table sending the execution command for the python file hbbtv-http.py
can you send us the PSI binary section (ait.sec) or TS (ait.TS) so we can check?
then i don't know if your test page is good for a red button splash.. BUT at least you should see the access from the TV set to you web server logs at
http://activeproduction.com/test/do you have web server logs? do you see the access from the HbbTv stack of the tv set?
the Tv set should be connected to the IP network, of course.. but i suppose you have already checked it..
bests
