Subject: DAB Receivers compatibility vs MOT

Dear Radio-L listeners,

I am working on program association data (PAD) synchronization for our
future  DAB Eureka-147 radio service (to be put "on air" sometimes next
spring) and the same question is always rising:

Why does none of the actual receiver displays PAD and DLS in the same
way?

Wait, I think that I will reformulate my question:

Is there any receivers and PAD inserters that fully support MOT 2.4? As
the Canadian national broadcaster, we are presently creating our firsts
DAB studios, and trying to anticipate the performance of the receivers
is very difficult. We still have no clue about how we will be able to
synchronize audio and data during our news bulletins, when each news
reports can be as different as a speech from the Prime Minister vs a
news flash about sheep cloning (imagine the problem we will face if the
synchronization is delayed by one image, and I haven't took the worst
comparison!).

Right now, none of the PAD inserter softwares in combination with any
of the DAB receivers that I was able to see, were giving may any
confidence that second-based synchronization will be possible in a near
future. I think that this issue will become crucial when the firsts
full-DAB services are going to be broadcasted. If any one of you have
some experience with synchronization of PAD (successful or not), it
will be great to share it with everybody.

Kind regards.
