Backhauls are used to get audio and video material to a main distribution point. Broadcasters such as Fox, ESPN, ABC, NBC, CNN, and CBS rely on SCS for backhauls from sports and news events to supplement their programming and newscasts. Using satellite, portable microwave, or TV1 fiber, SCS provides a direct path -- SD or HD -- back to the networks' head-end where the content is finalized and then distributed through the broadcast channels.
