Abstract

A system receives one or more content streams for a program including a Hypertext Transfer Protocol (HTTP) Live Streaming (HLS) master manifest file for the program, HLS media segments having different bitrate variants, and HLS media manifest files for each of the different bitrate variants. The system encapsulates the HLS master manifest file, the HLS media segments, and the HLS media manifest files into Internet Protocol/User Datagram Protocol (IP/UDP) packets and sends the IP/UDP packets via multicast to video serving offices. Network devices in the video serving offices extract from the IP/UDP packets the HLS master manifest file, the HLS media segments, and the HLS media manifest files. The network devices send to a cache device the HLS media segments and the HLS media manifest files; and forward the IP/UDP packets via multicast to devices in customer premises.
