Abstract
A system and method for facilitating fast channel change in a streaming media network comprises receiving media content assets packaged in a common mezzanine distribution format (CMZF) container structure, wherein the media content asset is provided as CMZF-formatted media content in a CMZF stream scheme. Upon receipt, the CMZF-packaged media content assets are transformatted into corresponding CMZF segments stored in a local cache corresponding to a plurality of media channels. Responsive to a channel change request from a user equipment (UE) device, a unicast or multicast burst is sent comprising Reliable User Datagram Protocol (R-UDP) packets or Real-time Transport Protocol (RTP)-encapsulated partial or full virtual segments (R-SEG) generated from the CMZF segments corresponding to the requested channel.
