Do you know if the NVP2440H dsp give better result than 2421 ?
I'm using CCTV HD-SDI camera modules plugged on a blackmagic ATEM for a theater set for a show (sorry for my english, I'm french) and I'm very happy with a board I bought on a china website with 1/3" Panasonic CMOS 34227 image sensor + NVP2421 (DSP)+ Divimath DM8600 (SDI converter).
The S/N ratio is >50dB witch is quite good. Very good image quality (with a 3MP varifocal 5-50 f/1.4
But... I need 4 more units and I found, on the same website, the same config except the DSP, witch is a NVP2040H instead of NVP2421... And the S/N ratio is given for >60dB
But before I buy the 4 units (more than 1 month delivery...) I want to be sure it will be not worse than the first I have...
I found 2421 and 2440H product description, but datasheet only for 2421...
Is someone have some experience with that ? Thank you in advance
