The transmission of the raw video feed from the remote location to the studio or master control is called backhaul. There are several ways of transmitting the backhaul:
The 23-centimeter band (1.24-1.3 GHz) is the third-lowest frequency band available for ATV. Analog big-dish satellite television receivers may be re-purposed for inexpensively receiving ATV in this band. Such receivers can decode FM television when an outdoor antenna is connected to the LNB input. Due to the low cost and ease of repurposing old ...
In a shared system, a receive antenna is usually located at the top of the antenna tower. Putting the receive antenna at the top helps to capture weaker received signals than if the receive antenna were lower of the two. By splitting the received signal from the antenna, many receivers can work satisfactorily from a single antenna.
The HR10-250 DirecTiVo units can also record HDTV to a 250 GB hard drive, both from the DirecTV stream and over-the-air via a standard UHF- or VHF-capable antenna.
