Hi again,
Thanks for the comments and feedback!
In this post I wanted to share some tips about the Samsung LED 3DTV used with the dual T90....
1. Configuring the Samsung TV for a DiSEqC 1.2 switch
The built-in DVB S2 tuner supports DiSEqC 1.0 and 1.2 - as well as USALS. To have access to the maximum number of LNBs I use it with a 16 port EMP-Centauri switch in DiSEqC 1.2 mode. Getting the TV to work with DiSEqC 1.2 switches is very easy:
In the satellite setup menu set
"Positioner Type" = DiSEqC 1.2
then under "User Mode" set
"Moving Mode" = discrete
"Step Size" = 10
You can now select LNB input on the switch by "moving" the dish a step East or West.
There is no need to do anything at all in "Installer Mode".
The rest of the procedure is the same as for any motorized system.... If you are unsure if you have selected the right input on the switch when configuring i.e. Astra 19.2, then just give it a try. Do a channel search and if it does not look right, just step East or West until you find another candidate. Do another channel search and so on....
There is no extra delay when using DiSEqC 1.2 on this TV. Intersatellite channel hopping is pretty instant.
2. Editing the Samsung TV channel lists on a PC
A nice standard feature on the Samsung TV is that can export/import the channel list to/from a USB stick. There a many free tools available to edit these lists - sort and delete channels, mark favourites and so on...
The maximum number of channels (TV or Radio) on the Samsung C series TVs is 5000.
3. Editing the Samsung TV transponder (and satellite) lists on a PC
This is my small contribution in terms of tools...
When you export the channel list from the TV you also export
the transponder list (TransponderDataBase.dat)
and satellite list (SatDataBase.dat)
(at least on my TV model/firmware version).
The file exported has a .scm extension. Rename it to .zip. Open it.
Inside you should find TransponderDataBase.dat and SatDataBase.dat.
These files are binary files, so I have attached a couple of Perl scripts I made which converts them into comma separated text (.csv).
Then these files can be edited and updated just as easy as satellites.xml on the Enigma-based receivers.
I have to give credit to the guys over at a German forum who posted the file format details.
There are at least two or three reasons why you want to edit TransponderDataBase.dat:
A. The transponder lists are outdated - at least for the less popular satellites
B. The first transponder on a satellite is important in DiSEqC 1.2 mode
When you switch satellite the TV apparently detects that is has found the correct satellite by "listening" on the first transponder in the satellite's transponderlist. If the parameters for this transponder are outdated, or if you can not receive it at your location, or can not receive it for any other reason ....the tuner goes into deadlock looking for the satellite.
During setup you can choose which transponder the TV uses when it searches for a satellite, but during normal operation it apparently only uses the first transponder in the list.
C. The LNB settings are the same for all LNBs in DiSEqC 1.2 mode
This is probably not a problem since most LNBs used today are of the "Universal" type.
However - when using a circular LNB or another LNB with i.e. a different local oscillator frequency, in combination with Universal LNBs (like I do), it can be nice to adjust the frequencies in the transponders lists accordingly.
I have played around with the attached scripts a lot, and made all kinds of mistakes, so I do not think there is any way you can brick the TV. Just have the original backup at hand, and import it back if required. There are however no guarantees - use any of the scripts at your own risk.
Cheers!
