half nim
I am developing a digital multimedia platform and I have to insert two TV tuners in it. Actually, I have three possibilities to implement each TV tuner module: 1) to use of a daughterboard with enclosed tuner and demod (NIM); 2) to use a daughterboard with only the tuner (half NIM), whereas the demod is on the motherboard; 3) to insert both tuner and demod on the motherboard.
I am using a 4-layer motherboard and also I probably will insert a re-modulator in order to spread to other TVs (through the same antenna cable) a descrambled and decoded transport stream.
I really have a lot difficulties in gathering enough information to be in a position to do an engineering evaluation about each of the above-mentioned three possibilities. Does anyone have some suggestions for me?
I need to know pros & cons, and finally I have to do an expense's evaluation.
Thank you for helping me.
