1 - pot transmite video alb/negru prin intermediul unui emitator/receptor IR, la o distanta de aproximativ 100 ml, fara obstacole sau alte interferente?
2 - se poate realiza o comanda IR cu 10 canale ful proportionale?
Daca raspunsul este pozitiv ma intereseaza sa realizez aceste doua proiecte, pe bani!!!
Astept cu interes raspunsurile voastre.
Multumesc!

Uite o sursa de inspiratie si de unde am luat afirmatia de mai sus (pe la minutul 4:53).

Parerea mea de ne-electronist expert, daca in 35MHz poti transmite 8 canale proportionale, apoi in IR am curajul sa spun ca merg si 100 canale. Gandeste-te la transmisia de date intre telefoanele de generatie veche cu infrarosu.

Se pare ca a continuat dezvoltarea IR (Giga-IR).
Mai jos mai multe link-uri cu ce am mai gasit.

Installation and Usage - Computer infrared network adapters both transmit and receive data through ports on the rear or side of a device. Infrared adapters are installed in many laptops and handheld personal devices. In Microsoft Windows, infrared connections can be created through the same method as other local area network connections. Infrared networks were designed to suppport direct two-computer connections only, created temporarily as the need arises. However, extensions to infrared technology also support more than two computers and semi-permanent networks.
Range - Infrared communications span very short distances. Place two infrared devices within a few feet (no more than 5 meters) of each other when networking them. Unlike Wi-Fi and Bluetooth technologies, infrared network signals cannot penetrate walls or other obstructions and work only in the direct "line of sight."
Performance - Infrared technology used in local networks exists in three different forms:
IrDA-SIR (slow speed) infrared supporting data rates up to 115 Kbps
IrDA-MIR (medium speed) infrared supporting data rates up to 1.15 Mbps
IrDA-FIR (fast speed) infrared supporting data rates up to 4 Mbps

EDIT : acum am citit mai bine :

ce am eu nu este proportional din pacate. Este doar ON/OFF.

Doar ca cele doua parti trebuie sa aiba vizibilitate permanenta, au lentile concentratoare si sunt asezate in pozitie fixa, colineara, ceeace e greu de asigurat daca va ganditi la controlul unui model.
De video nici nu imi pun problema.
