Re: DSM-CC Synchronized Download Protocol

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



DSM-CC is used a lot in ISDB-T / ISDB-S for data broadcasting and
firmware download.
Have a poke around http://www.dibeg.org/aribstd/ARIBSTD.htm
One of B-xx standards should cover DSM-CC related stuff. I know it
does because I wrote a parser for DDI and DDB messages a few months
ago. By the way, the stuff follows standard section table format.

thanks, that explains at least why there's nothing to find in the
original specification. But it seems the paper is not available for
free. Before i spend money on this (though its not much) id like to know
a bit more about it. Also most of the iso standard papers do not include
much info about the practical use.
So maybe anyone who worked with this can explain me some details:
- does this method require flow-control (kommunication with the server)?
- what are the requirements for a receiver to manage dsm-cc download
sections ?
- is there support of this method in DVB? (since i only know of the
DSM-CC caraousel being used in DVB)


regards,
Thomas
