1.3.4 Over-air Software Download(TANDBERG Director Systems)The TT1260 Satellite Receiver is shippe d with the appropriate software
installed, but it is designed t o allow replacement of this code by new
versions of software transmitted over-air. The new code is downlo aded 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 rece ived, installed and validated, it is loaded int o the
active memory and becomes the operating software for the Receiver.
