Methods, systems, devices, and computer-readable media for delivering additional content using a multicast streaming

摘要

A system and method for improving media delivery and display. By utilizing a memory buffer in a DVR or similar device, and broadcasting linear content at a rate other than 1×, services like video on demand or regular broadcasters can be more versatile. For example viewers can start over without launching a separate VOD session. If part of the linear content requested is not in the buffer, a switched multicast stream can be sent to with the proper section of content. Other receivers on the network may also receive the stream and buffer the content if the content is related to what a viewer is viewing.
