Abstract

Presented are methods for converting a multicast media stream to unicast segments, for delivery over generic IP networks such the Internet. The unicast segments can be converted back again to a multicast stream that is identical to the original multicast stream closer to the consuming client device. Information required to regenerate a multicast stream from the generated unicast segments that is identical to the original multicast stream is also encoded into the file name of the generated unicast segments. Additionally, RTP header information from the multicast stream that is not required when the unicast segments are generated are stored in files linked to the generated unicast segments, enabling the multicast stream that is regenerated to be identical to the original multicast stream even at the RTP level.
