UK Digital Interactive - Red Button (MHEGPlugin)

McGoober · 2006-11-14, 16:54

I have started work on an Interactive Digital (Red Button) plugin for the UK.

Here is an example of the UK interactive services available on some channels.
http://www.bbc.co.uk/digital/tv/tv_interactive.shtml

The plugin will consist of two parts ...
The first will plug in to the new TVServer and provide DVB Object Carousel data probably in the form of a HTTP server.
The other will be a visual plugin for MediaPortal to operate in a similar way to analog teletext.

The heart of this MediaPortal plugin is a standard called MHEG.

Any thoughts, suggestions and comments are very welcome.

My current progress...

I have been porting the FreeMHEG library included in MythTV 0.20 to C#. It's hard going but I'm about 60% of the way there and I'm seeing some results.

Here is an MHEG example I found.
Attached is the image I got from my MHEG engine

You will notice that the buttons don't show, this is because buttons are not part of the UK MHEG profile, which is what I'm working towards.

Cool !

I've seen many a post over the years across various HTPC forums -- like Sage, MCE and more recently [for me

] MP to see an MHEG plugin to keep those UK "red button" users happy.

Looks like MP will get there first -- way to go !

Thanks McGoober

McGoober

All the best mate, have seen lots of requests for this one across various forum's, and your the first person i've seen to take up the challenge.

Big Regards.

Major cudos to you McGoober for tackling this one!

Respect !

I started looking at creating structs and methods to parse the PSI tables, DSM-CC messages into object and data carsousels and then sort the DII DSI modules... that's about as far as I got... do have the DSM-CC structs though... I was using the ETSI TR 101 202 and 'theredbutton' project as a guide.

ETSI is a good detailed guide of the Object and Data Carousels but not of MHEG.

Never got round to looking at the front end, but I was hopeing that the object wouldn't be to disimilar from the the GUIfactory items to allow for overlay.

Nice to see somebody else having a crack...

Hope you get there.

Oh forgot to add...

BBC1 etc just broadcast a DSI, the DSI points to a carousel on the BBCi elementary_pid. To access the carousel for BBC1 you'll have to read from the BBCi PID but ignore the BBCi DSI

Just to make things more complicated... still utmost respect...

Hey Flipit, looks like we started from opposite ends. Interesting... Maybe we could pull some resources and figure this out together. Best I get in contact directly.
