Patent ID: 8380242

Claim:
A method for audio and video communication for use in an electronic device comprising a digital signal processor (DSP) coupled to a microphone, a radio frequency (RF) transceiver and a transport unit, the method comprising: repeatedly generating a plurality of first acoustic objects corresponding to sound signals detected by the microphone and a plurality of second acoustic objects corresponding to sound signals from a remote mobile electronic device of a cellular network via the RF transceiver, when the electronic device operates as intermediate device between a cellular network and a Internet Protocol (IP) network; mixing the first and second acoustic objects to generate a first mixed acoustic object, receiving a plurality of third acoustic objects from a remote electronic apparatus of the IP network via the transport device coupling to a computer host of the IP network, and mixing the first and third acoustic objects to generate a second mixed acoustic objects, wherein the generated first mixed acoustic objects are repeatedly transmitted to the remote electronic apparatus of the IP network, and the generated second mixed acoustic objects are repeatedly transmitted to the remote mobile electronic device of the cellular network, so that a three-party call among the electronic device, the remote electronic apparatus of the IP network and the remote mobile electronic device of the cellular network is established.
