The multicast protocol for adding broadcast-like functionality to the Internet has been around for nearly two decades. Various technical limitations, however, have impeded its widespread adoption. Could it be making a comeback?
Yes, if for no other reason than the advent of IPv6, which activates IP multicast by default. It may also gain traction by way of secure multicast for advanced repeating of television (SMART), a technology developed by Ventura CA-based startup Worldcast.
An early investor in Worldcast was Ray Miller, a Cable Television Pioneer, past chairman of the NCTC, a director of the Outdoor Channel and current chairman of Country Cablevision. Miller said he believes that multicast has the possibility of turning the traditional cable television programming distribution model on its head.
