Hello,

I am interested in build a dsmcc decoder beginning from libdsmcc. First I
created an object carousel with dsmcc-mhp-tools [1] and using libdsmcc [2] I
could process some sections. Until now I could decode simple DSMCC TS files
with a few files encoded. Anyone is interested in a dsmcc decoder to work
together or has any documentation to help me?

I think some people will be happy to have a DSMCC client reference
implementation, thats sure :)
Where do you want to start a project for that?

You can find some documentation inside the MHP specification which you
can download from
http://www.mhp.org/documents/Ts102812.V1.2.1.zip
Look into Annex B, there's nearly all required information about
Object Carousels and references to other documents.

This is the encoder I wrote for MHP application broadcast.
The generator is not very configurable, but just good enough to start
with and good for testing ;)

This URL is broken... I don't know how suitable it is for your
project, I don't know what functionality (TS and message parsing
would be sufficient) it does provide though.

I can help you with your project but have little time right now.
Cheers, Marek

I think dvbsnoop has code to parse individual dsmcc packets, but
doesn't do anything useful with them.

Hi,

I've written a DSM-CC client that will download object
carousels onto your local hard disc, get it here:

http://www.redbutton.dsl.pipex.com/

I've been trying to feed the data into this MHEG engine:

http://www.prz.tu-berlin.de/~joe/mheg/mheg_intro.html

with little success - it wont parse the scripts that get
broadcast here in the UK - anyone know of any other open source MHEG
engines?

This implementation is ancient and AFAIK predates the
UK-MHEG profile (i.e. it tries to implement the "raw"
ETSI MHEP spec). It also has only a parser for the
textual MHEG representaton, not for the ASN.1 encoded
applications which are used in broadcast.
