A communication system is provided that is preferably a peer-to-peer (p2p) system. One or both of audio and video can be transferred among a number of user terminals in the p2p system. The user terminals can include at least one master terminal, which could be an unhosted master terminal that does not communicate its own audio and/or video. In one embodiment, a first master terminal is included that controls video or audio, or both, transfers among user terminals and an unhosted second master terminal is provided that communicates with at least two user terminals to provide desired connectivity involving such user terminals in order to ensure proper audio and/or video communications between or among them. In another embodiment, an unhosted master terminal is provided with the communication system when the user terminals include mobile terminals in order to avoid power usage by mobile terminals. This communication system can be utilized with online game playing in which a game server is included, as well as having other communication applications.

1. At least one non-transitory computer readable medium for storing at least one computer program related to whether to include a master terminal in a network, said at least one computer program comprising instructions for: obtaining information using each of a number of mobile terminals in a network being established, said number of mobile terminals being greater than one, said information related to each of said number of mobile terminals being identified as a mobile terminal; andusing said information to determine, after said obtaining, to include said master terminal in said network, with said number of mobile terminals also being greater than a predetermined number wherein, when said number of mobile terminals is not greater than said predetermined number, said master terminal is not included in said network, and in which said number of mobile terminals in said network after said master terminal is included remains the same as said number of mobile terminals before said master terminal is included in said network. 2. At least one non-transitory computer readable medium of claim 1, wherein said master terminal, after being included in said network, receives audio data associated with at least each of said number of said mobile terminals and with said number of said mobile terminals not being fully interconnected such that each of said number of mobile terminals does not receive audio data directly from each other of said number of mobile terminals, and in which said network is subsequently changed wherein said number of said mobile terminal are fully interconnected such that each of said number of mobile terminals does receive audio data directly from each other of said number of mobile terminals. 3. At least one non-transitory computer readable medium of claim 1, wherein said network includes a plurality of user terminals and said plurality of user terminals includes said number of mobile terminals and in which all said plurality of user terminals are mobile terminals. 4. At least one non-transitory computer readable medium of claim 3, wherein said predetermined number is four and said plurality of user terminals is five. 5. At least one non-transitory computer readable medium having at least one computer program related to whether to include a master terminal in communication with a plurality of user terminals including at least two user terminals involved with communicating one or both of audio and video, said at least one computer program comprising instructions for use in: sending data between at least first and second user terminals of said plurality of user terminals; andafter said sending data, adding a first master terminal in a network that includes said plurality of user terminals including said first and second user terminals;wherein data is sent between said first and second user terminals before said adding said first master terminal, and data is also sent between said first and second user terminals using said first master terminal after said adding said first master terminal, and in which said number of said plurality of user terminals in said network after said adding said first master terminal remains the same as said number of said plurality of user terminals before said adding said first master terminal. 6. At least one non-transitory computer readable medium of claim 5, wherein said second user terminal is a second master terminal and said first user terminal is a first slave that communicates audio data associated therewith to said first master terminal and in which said first master terminal communicates said audio data associated with said first slave to said second master terminal. 7. At least one non-transitory computer readable medium of claim 6, wherein said first master terminal is an unhosted master terminal and said second master terminal is not an unhosted master terminal with said second master terminal communicating its own audio data to said first slave using said first master terminal. 8. At least one computer readable medium of claim 5, further including a second slave and said first user terminal is a first slave and said second user terminal is a second master terminal, and in which said first slave communicates its own audio data to said first master terminal and said first master terminal communicates said first slave audio data to said second master terminal and said second slave communicates its own audio data to said second master terminal and said second slave does not communicate its own audio data to said first master terminal. 9. At least one non-transitory computer readable medium of claim 5, wherein a determination is made utilizing at least one data bit controlled using at least one of said first and second user terminals, before said first master terminal is added, that at least one of said at least first and second user terminals is a mobile terminal. 10. At least one computer readable medium of claim 5, wherein said plurality of user terminals are used in establishing a particular peer-to-peer network, with at least each of said first and second user terminals for outputting audio data associated with said first and second user terminals, respectively.
