[mythtv] DVB Features (Subtitles & Interactive)

[Paul Wheeler]

Hello all,

I have two questions about the state of DVB in Myth, I am based in the UK.

Subtitles
=====

I have a deaf housemate and would *really* like to get these working.
>From what I gather(please correct me if wrong) you cannot get these
currently with the DVB setup. Is anyone actively working on these at
the moment or are they at the bottom of some list (I understand for
most people they are not used). If they are at the bottom of the list
why is this? Is it because developers have better things to work on
but the solution is not too tricky its more a time thing they dont
work yet. OR is it that they are very difficult to implement so dont
work yet.

If it is more the first I would like to start looking into these, as I
understand it there are two methods of subtitles with DVB, teletext
and a PID. Which would be easier and what have people looked at?

Interactive
======

I dont know if this is a uk only thing as havent heard it mentioned at
all on the mailing lists. Can  Myth handle 'going interactive' an
example is the BBCi service. From what i can tell from scan etc this
has its own PID with the information. Again what is the state with
this, have people looked at it in the past and turned it away for some
reason (what was that reason). In interactive you get a menu and can
select different streams to watch. Does anyone know if this is a
hardware issue?




I do a lot of programming but havent touched the Myth source code at
all so would like to know if it is worth me spending a lot of time
investigating the code and trying to write some patches or that it
will be too much effort or ideally someone else is already doing it
and almost there.

Cheers
Paul
