Re: Fw: [linux-dvb] DSM-CC question
Hi, I need help to understand stream and stream event messages. Stream Message: I can read upto message length. But after that what is the use of taps and if i process those taps, what information do i need to store on filesystem and how that information can be used. Also, In what cases in DVB-S DSMCC we can get stream message and what is the use of it. As far as I understand all the useful data is in file messages.(dir and srg are required to get proper structure but actual contents which can be used are in file). Stream Event Message: Similarly, with stream event message what is the use of taps and how to process them. Also, what is the use of event ids in this message and why do we need to store it or use it? Thanks for help. - Original Message From: Peter Evertz To: Simon Liddicott Cc: Suchita Gupta ; linux-media@vger.kernel.org Sent: Wed, 15 September, 2010 19:05:43 Subject: Re: Fw: [linux-dvb] DSM-CC question Or take a look at "mhp" or "dsmcc" plugins for vdr.

Re: Fw: [linux-dvb] DSM-CC question
Hi All, Thanks to everyone for their help. I am able to build a tree from DSMCC carousel. I have done only file, dir and srg messages at the time being as I don't understand the usage of stream and stream event messages at the moment. Can anyone please explain these to me and how can they be assembled.

Or take a look at "mhp" or "dsmcc" plugins for vdr. Both not activ projects, but both have a dsmcc implementation. Are you working on a "hbbtv" solution ?
