[opendtv] Re: News: Those licenses will soon be worthless...

I'd like to see the interface document.  I suspect, however, that I might
not need it; my PSIP system was tested there last fall, and I only lacked
proper CRC-32.  Caveat: we didn't test against, and I hadn't written, the
real-time part to deal with program preemptions and table changes at the
three hour mark.  I've since written this part, but have yet to test it; and
won't until I finish EtherGuide Ferret in the next week or two.

Just last night, I wrote the function needed to do 32-bit unsigned integer
addition in visual basic.  The first use will be in the crc-32 algorithm (as
I just posted to my PSIP list) on the t&m side.  Then, I will be able to
finish the EtherGuide Ferret PSIP generator, with full Directed Channel
Change support.

You can UNSUBSCRIBE from the OpenDTV list in two ways:

- Using the UNSUBSCRIBE command in your user configuration settings at 
FreeLists.org 

- By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word 
unsubscribe in the subject line.
