Abstract
A method, a system, and a non-transitory storage medium provides to receive a program including audio and video data; generate Moving Picture Experts Group (MPEG) Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (MPEG-DASH) segments that have multiple bit rates; transmit first packets that include the MPEG-DASH segments; divide each of the MPEG-DASH segments into first multiple slices of program data; generate a first header for each first slice of the first multiple slices, wherein the first header includes sequence information; multicast second packets that include first headers and the first multiple slices of each of the MPEG-DASH segments; assemble the MPEG-DASH segments; divide each of the MPEG-DASH segments into second multiple slices of the program data; encapsulate the second multiple slices into third packets; generate forward error correction packets; and multicast to a user device of a multicast, the third packets and the forward error correction packets.
