What MCU or processor is suitable for operating it? Where can I find information for operating this? I couldn’t find any datasheet.
I would get an extra remote control for the receiver, and mount it in such a way that it sits on top of receiver, and shines down on the IR window of the receiver perhaps using a mirror. Then hack into the remote control, and wire into the buttons that you need to operate the receiver. The easiest way to do this, without trying to figure out the input circuit of the remote, is to wire reed relays across the contacts note that the buttons probably don’t actually have contacts in themselves, but may operate dome switches or some other type of switch contact located on the PCB of the remote controller.

If you want to get fancier, and use less satasheet, you will probably find that the conact switches are arranged in some sort of array for example, 6×6 would use 12 wires, but would allow for 36 buttons. So then you just have to control the appropriate two wires for each button. In either case, I dayasheet attach a couple of wires to a single button first m3329d as Muteand try connecting them manually and observing the result. Beside reed relays, it would probably be possible to go all solid state using FETs, but you would need to reverse engineer more of the circuit.
Here is the last place you would look for such information: You won’t find the datasheet, but you will find the source code of a driver for a DVB card with the same tuner.
You just have to adapt the code. The code I will provide is adapted from m3329e The following pseudo-code is just an adaptation of the original code Copyright C Igor M. I only removed specific kernel routines and rewrote the I2C communication routines. Thank you for your interest in this question.

How do I operate a tuner of digital satellite receiver using a microcontroller? I want to operate this tuner of my digital satellite receiver. This is the tuner: They wrote some numbers and words around of the tuner: I think that’s probably just the analog front-end to the tuner; the large “ALi” IC will contain vital parts of the tuning and decoding process.
What do you mean by “operate”, anyway? From the look of the two orange capacitors above and on the right the power transformer, you had better finish your project soon.
No, please datasheeet take more photos. A bulging electrolytic capacitor indicates a higher probability of failure.
Your board appears to be 5 or 6 years old so that’s not unusual, but those capacitors may fail sooner rather than later.
While tcrosley answer is a good avenue to look into, it’s way more complicated than needed. You don’t even need a second control, or relays or anything. Most standard remote controls can be emulated in software.
Arduino, msp launchpads, any modern microcontroller can do it quite easily. But that said, it seems like OP might be looking into directly accessing the tuner, not the entire receiver.
OP hasn’t really clarified. Replace with your code. Cornelius 4, 2 18
