1.2 Location of AERO.mobile
Mobile DTV operates slightly differently than standard DTV. It uses different video and
audio coding, but it also connects to the multiplexer via an IP connection over Ethernet.
Theoretically, this means that Mobile DTV encoding can be located just about anywhere,
but likely will be at the station for connection to baseband audio and video sources. Since
AERO.mobile accepts baseband audio and outputs a signal for encoding, a good installa-
tion point would be very close to the Mobile DTV encoder as shown below in Figure 1-2.
