A system can include one or more content distribution sites to provide content to one or more content satellite offices for delivery toward a set of destination devices for display. A content distribution site, of the one or more content distribution sites, can include one or more streamer devices. The one or more streamer devices can be associated with a single spoofed Internet protocol (IP) address. The spoofed IP address can facilitate failover among the one or more streamer devices. The one or more streamer devices can be configured to provide the content toward the set of destination devices using multicast with forward error correction (FEC). A content satellite office, of the one or more content satellite offices, can be configured to subscribe to a multicast group associated with the one or more streamer devices. The multicast group can be associated with the spoofed IP address to facilitate the failover among the one or more streamer devices.

Content stream integrity and redundancy system

A method, a system, and a non-transitory storage medium provides to receive Moving Picture Experts Group Dynamic Adaptive Streaming over Hypertext Transfer Protocol (MPEG-DASH) segments that have multiple bit rates of a program; divide each of the MPEG-DASH segments into first multiple slices of program data of the program; generate first header slices for the first multiple slices, wherein each of the first header slices includes sequence information and an identifier of one of the MPEG-DASH segments; and multicast second packets that include the first headers and the first multiple slices.

MPEG-DASH delivery over multicast

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.

A method, a system, and a non-transitory storage medium provides to receive multicast protocol packets, wherein each of the multicast protocol packets includes one of a slice of program data of a Moving Picture Experts Group (MPEG) Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (MPEG-DASH) segment and a header of the slice that indicates sequence information of the slice relative to other slices, or forward error correction data; order, in response to the receipt of the multicast protocol packets, each slice received based on the sequence information; determine whether any slice is missing that is a part of the MPEG-DASH segment; determine, in response to a determination that there are missing slices, whether the missing slices can be recovered; and use, in response to a determination that the missing slices can be recovered, the forward error correction data to recover the missing slices.
