Though the list is entitled the SCTE mailing list, it is not affiliated with The Society of Cable Telecommunications Engineers. The list is operated by David Devereaux-Weber at the University of Wisconsin. Postings to the list are bundled into a daily digest so that subscribers are not subject to many individual pieces of e-mail.
Discussions cover all aspects of the industry.
However, most posts are technical in nature. Since the list is not moderated, there are a lot of inappropriate postings. The digested form minimizes the annoyance of these posts and has saved the list from death by over-population. If you have a question that is CATV related, this is the most effective place to ask it. Posts to the list are sent out once a week in a digest form or when applicable.
