With the success of podcasting — a recent technology that lets anyone subscribe to and play back audio feeds on an iPod — the natural next step is technology that can do the same with video.

First a podcasting primer: It works much the same way as syndication of content through RSS or Atom, except that instead of text from blogs or news sites, podcasting sends songs directly to iPods or other MP3 players.

Now comes video. Already, there are rudimentary applications like Vogbrowser, which offers video feeds to which people can subscribe, much like they do with RSS feeds. There are more products like this on the way.

“We think of it internally as TiVocasting,” said Scott Rafer, president and chief executive of the blog search engine Feedster, which has begun offering video feeds through a dedicated site, FeedsterTV. “Video stuff is now coming into play. It’s one thing to have a bunch of video files dumped into a folder on your desktop. The interesting future is when it is put into a TiVo-style mechanism.”

Right now, there isn’t much video content to view this way: It’s mostly lectures, tutorials and clips cribbed from the Jon Stewart show. And it takes some technical know-how to hack a Linux box to play back the feeds in applications like Vogbrowser. Unlike podcasting, which uses a consumer-friendly device for playback, there is no easy method for automatically transferring video files onto a TV.

For now, the early grunt work is being done by people like Kenyatta Cheese, Vogbrowser’s developer, and Jay Dedman, a New York television production teacher.
