[linux-dvb] DVB user-defined descriptors

[Dave Chapman <dave@dchapman.com>]

Hello,

I've been examining the various descriptors broadcast in the service 
information by various networks on various satellites.  My only references 
are ISO-13818-1 (the MPEG standard) and EN 300 468 (the DVB-SI standard).  
According to those references, a lot of the descriptors I am finding are 
listed as "user defined".  

Is there any documentation available on these?  Are there any other standards 
that define descriptors apart from the two I mention?

An example is descriptor 0xc5 - this is easily interpreted and contains an id 
number and channel name for Canal Satellite radio stations on (e.g.) Astra 
19E.  These differ to normal Radio Stations because they are all transmitted 
as part of the same service - in effect multiple audio channels.  This 
descriptor is listed as "user-defined" in EN 300 468 - is it defined in any 
public standards document?

Thanks,

Dave.
