ABSTRACT:
A communication system includes a HAVi-based in-home network140and a remote device110operative to communicate with an intermediate device130of the in-home network via Internet. The remote device loads a HAVi applet (Havlet)238for controlling at least one of the in-home devices using HAVi. The remote device also loads an HAVi API (HJA) emulator310which emulates HJA. The HJA emulator provides an interface for the Havlet and communicates with a module330in the intermediate device. The intermediate device includes the actual HJA236which provides the actual interface functionality for the HAVi functions used by the Havlet. The interface functionality is provided by controlling the intermediate device and/or communicating with other in-home device(s) according to application messages of the in-home application protocol. The intermediate device loads the module for enabling communication between the HJA emulator in the remote device and HJA loaded in the intermediate device, giving a substantially transparent communication path between the portable application program in the remote device and the HJA in the intermediate device.
