1) irp_classes [Link: github.com]
This php classe implements the core algorithms required for working with IR remote controls, i.e. encode and decode RAW IR commands, using informations about the IR protocol in 'IRP notation'. The irp_classes is an 'execution process' for IRPs, extended to encode and decode processes of IR raw streams.

2) remotesDB [Link: github.com]
This is my attempt to define a 'good' database for IRPs and to use with irp_classes. It must be a starting point for building home automation applications. As demo of remotesDB capabilities, an application to perform a simple replica of all IR remote controls (with static and dynamic keys, like aircon).
You can see it as an example of using remotesDB and the included php libraries you can use in your IR applications.
