Difference in DVB tuning between Tizen 4 and Tizen 6

is there a fundamental difference in tuning a DVB stream between a Tizen 4.0 (EJ690) and Tizen 6.0 (AU800).

Procedure for Tizen 6:

  1. create tvwindow globally once
  2. Set tuneOptions parameter
  3. call “broadcast.tuneDirect(tuneOptions, this.callbackSuccess, this.callbackError);”.
  4. how to stop the tuned channel again?

Under Tizen 4:
Using the same procedure as for Tizen 6, the channel is only played when I leave the channel again.

There seems to be a difference in tuning.
Thank you.
