Relaunching subject about Video streaming using 433mhz module (like chromecast)

Sorry for my bad english !

I have the feeling that most of the members who responded on this topic did so too quickly. This is why I would like to relaunch the subject, so that we think about it more seriously. Because it could be a fantastic and extremely affordable project.

It is clear that if we make only one link connection, that the speed could not meet the demand. However, what about when using all 4 channels (on a small module such as the FS1000A), for example. I would even like to take the idea even further.

Imagine that using an fpga or a microcontroller, we operate the RF module with a dynamic approach. For example, instead of defining a module with a static configuration of its addressing, we instead define channels, say 16 channels. Each channel represents a unique address on the module to send / receive a data packet (4 bits x Clock of the RF module) X our 16 channels defined in the micros. Finally, you kinda get the idea. And with registry chipset to created sufficient buffer memory. We would, hypothetically, be able to generate a stream that would probably transmit 4K video quality. Using 2 RF modules, to separate the sound and the image, with 2 micros to reconstruct the packets and a 3rd micro to recombine and synchronize the sound and the image. With few components, the project becomes, in my opinion, something possible.

Of course, it is only hypotheses that I launch like that, because for my part, it is a project that I would like to happen. If the project comes to fruition, imagine the possibilities that this approach would offer. To open up new horizons on how to optimize a data flow by harnessing the potential of modules with a completely different, but innovative approach!

Before you get too far with your thought experiment, spend some time researching the legal requirements for using the 433 ISM frequencies in your country.

Very unlikley to be legal or nice to attempt that at 433Mhz.

Use 2.4Ghz, World wide band and normally with no duty cycle restrictions.

Doubtful.
I really don't think the processors in the Arduino family are fast enough.
You may also run into interference with multiple transmitters.

You might have better luck with the ESP32 boards. The ESP32 chip has 2 CPU cores and a clock frequency of 240 MHz.

You write of synchronizing stuff, but provide no detain on what you would use for the synchronization, not how you would accomplish it. You might think of including a time stamp with each sample of each type of data and then attempt to combine them into what?
