I'm looking for an expert in OTA EPG for North America. I want to pull the EPG data from the linear stream before I hand it off to the transcoder. Right now, the signal hits my antenna and then goes through my Silicon Dust tuner which outputs the channels in IP multicast. Surely, someone out there has technical info on how to pull the guide data or even code that does it. The ATSC 1 standard has been out there for a while. Thanks for any help.
