My most recent ts captures of KPBS-DT show stream_type 11/0x0b mandated by 
A/97.  I'd assert that they have been providing this service for some time; I 
know from personal discussions with the station and bdc that the agreement has 
been in place for at least a year.  

The details I can glean with the (still in development but to be finished in a 
week or so implementation of EtherGuide Ferret): the packet stream is on pid 
97/0x0061, the pmt on pid 48/0x30.  I'm currently using file input only at 
better than 2x bit rate, but the bit rate for pid 97 is around 240kb/sec.

The spec was only published by the ATSC on Nov 16, 2004; the ATSC has not "been 
working on it for some time" but it hasn't been around for long enough to get 
into tv sets or stbs, and I was told by BDC at last year's nab that they didn't 
expect any consumer-side implementations to come to market until later this 
year at the earliest.

Of course, the good reason for using a San Diego dtv station for transmission 
tests is that development of most of the world's dtv sets is done here.  
Indeed, Mike Dolan, the chairman of the ATSC subcommittee is a local resident.

Is this another one of your dual posts to opendtv and the san diego dtv list?  
Seems an odd way to communicate, since there's a wider audience on this list,  
and there is little overlap between the lists.

You could have discovered this yourself with approprate equipment to demux the 
transport stream, and Leon Messenie, CE of KPBS, is apparently a local call for

"KPBS-DT in San Diego announced that they will broadcast fol. Automated 
Software Update for DTV Equipment service:
I was aware that ATSC had been working on defining the Software Data Download 
Service in ATSC Document A/97:

Does anyone know which HDTVs or OTA STBs that actually implement this software 
update service???
I can't recall ever seeing this mentioned in any manufacturer's website....

This would provide an automatic software update service roughly equivalent to 
what we take for granted for CATV and DVB."
