Abstract:
1. A system for managing Internet Protocol of at least one of unicast and multicast communications over a network, the system comprising: network interface means for interfacing between the network and other parts of the system; signal processing means connected to the network interface means having at least one audio channel for decompressing and de-packetising audio signals received from a plurality of remote systems through the network interface means and for outputting the audio signals to audio mixer means for mixing the received audio signals at different respective audio levels relative to the respective remote systems such that a resultant audio mix has no component resulting from local mixing of the system's own audio input, nor any component resulting from mixing at the respective remote systems so that the audio mix is a full mix of audio signals from the remote systems mixed by the system with no local source audio and having at least one audio channel for compressing and packetising audio signals received from the audio mixer means mixed at different respective audio levels for transmission through the network interface means over the network; audio channel manager means connected to the signal processing means for dynamically allocating the audio channels in the signal processing means and connected to the audio mixing means for signalling an allocated channel to the audio mixing means; and message manager means connected to the network interface means and to the audio channel manager means for managing the at least one of unicast and multicast communication of the audio signals.
