backhaul




- Backhaul, a term probably derived from the trucking industry, has several usages in information technology.
1) In satellite communication, backhaul is used to mean getting data to a point from which it can be distributed over a network. For example, to deliver a live television program from Chicago to authorized DirecPC satellite terminals around the country, the video signals would have to be backhauled by some means (by optical fiber cable or by another satellite system) to the Hughes DirecPC facility in Germantown, Maryland. From there, it would be uplinked to the Galaxy IV satellite from which DirecPC users could view the broadcast (receive it in a downlink from the satellite at their individual terminals). Backhauling is also used to get non-live audio and video material to distribution points at the major broadcast news organizations for broadcast in the evening or ongoing news.
