1.3.4 Over-air Software Download
(TANDBERG Director Systems)
The TT1260 Satellite Receiver is shipped with the appropriate software
installed, but it is designed to allow replacement of this code by new
versions of software transmitted over-air. The new code is downloaded as
a background task in the same transport stream as used for the normal
transmission of services.
Figure 1.5 shows the system required for this function. The existing
software continues to function during the download process. Once all the
new code has been received, installed and validated, it is loaded into the
active memory and becomes the operating software for the Receiver.
