Abstract: Embodiments for controlling one or more external audio-visual devices are provided. In one example, a method comprises receiving a device command and determining an intent of the device command. The intent includes an action and an external device to perform the action. The method further comprises selecting a selected protocol for communicating the device command to the external device, where the selected protocol is selected from a plurality of supported protocols, and communicating the device command to the external device according to the selected protocol.

Abstract: Different target functions at a target computing platform having limited resources are invoked by a single generic function call from a calling computing platform having substantial resources. A target function can be called in a consistent and efficient manner, so that custom code can be avoided at the target computing platform for each target function. The generic function call can have parameters which identify a memory location at which a target function is stored, and one or more parameters to be passed to the target function in a format (e.g., length, endianness, enumerated data type, structured record type, float or integer type) which the target function uses, so that further conversion at the target computing platform is avoided. Parameters can also identify a thread and processor on which the function should run. The target computing platform loads and executes the target function using the registers in a deterministic way.
