Abstract

Mechanisms are provided for generating and modifying live media streams. A device establishes a session and requests a media stream from a content server. The content server provides the media stream to the device. The content server also obtains an insertion stream for inclusion in the media stream. Packets are removed from the media stream to allow inclusion of the insertion stream. Timestamp information and sequence number information is maintained to allow uninterrupted delivery of the modified media stream.
