LTC is what the customer needs as an input for his equipment, so whatever encording used on DVD I need to produce LTC as an output. It really does not matter, my problem is how to capture the timestamp data. -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu]On Behalf Of Dave Tweed Sent: Saturday, October 19, 2013 3:00 AM To: piclist@mit.edu Subject: Re: [EE]: LTC signal from DVD player: how? You keep saying LTC (linear time code), which is normally recorded in an audio track, but it's much more likely that video equipment would produce VITC (vertical interval time code), which carries the same information in the veritcal blanking interval of an analog video signal. It is encoded in a manner similar to (but distinct from) closed-captioning. -- Dave Tweed -- http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
