(If this is the fourth copy of this I apologize up front. Webmail interface is screwy tonight.) We feed our boob tube Directv so getting the PBS time signal to the VCR requires some thought. I could stick up an antenna to catch the local stations and feed that to the VCR but that wouldn't require a PIC. http://www.robson.org/gary/writing/nv-line21.html# I was thinking of feeding a GPS or NTP time signal to a PIC and have it generate VBI line 21 data. Anyone looked at decoding or generating XDS packets with a PIC? -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
