Resources: Baseband settings

It’s useful to have these settings to hand in case they get corrupted by stray STB remote button presses, while you’re using a different set-top box, or when working in a crowded office environment.

OpenTV baseband STB settings

Don’t forget that the network id has to match the value used in an SI information you’re going to send to the STB to kick start it. For SI information used by developers at Sky the correct value may well be 00002.

network id00001
symbol rate27.500
fec inner2/3
lnb freq10.000

When you subsequently ‘start’ your baseband STB, you should then see debug similar to the following:

Finding a network with network id of 1

The settings that you applied earlier will be reflected here. When you then play out a PSI file, in preparation for playing out your mux of development content, you should see something like this:

New version of handle
