1. A system for audio and video communication used in an electronic device, comprising:

  • a digital signal processor (DSP) coupling to a microphone, a radio frequency (RF) transceiver and a transport unit, and when the electronic device operates as intermediate device between a cellular network and a Internet Protocol (IP) network, 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, mixing the first and mixed acoustic objects, 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.
