To: multimedia@freebsd.org Date: Mon, 17 Feb 1997 18:40:59 +0100 (MET) X-Mailer: ELM [version 2.4 PL23] Content-Type: text Sender: owner-multimedia@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi, I was wondering if any of you has used a video grabber to acquire and decode Teletext data. I just checked with the meteor, and the data lines are reasonably clean to store them on disk and attempt a decoding in software at a later time. The Hauppauge board might actually use this method. The (net) data rate is about 36 KB/s, although saving data to disk using Y only might require 8 times as much storage.
