Abstract:
1. A method of videoconferencing service utilizing fourth generation wireless technology to provide full duplex exchange of digital streaming video and sound comprising: two terminals, each selected from a group containing television receivers and cellular telephones and wireless terminals and laptops, wherein each terminal equipped with a display screen, a fourth generation wireless cellular network interface, a digital video camera, a microphone, a loudspeaker and a logic device employing subscriber routing tables wherein selection of a terminating video subscriber routing table address causes a 4G terminal originating a video call to instruct a 4G network to set up a 4G communication channel with the bandwidth necessary to support streaming video and sound on a full duplex basis; to configure an originating terminal to carry full duplex video and sound and to be parametrically compatible with the terminating terminal; to provide routing information to the fourth generation wireless cellular network, wherein each user's wireless terminal will contain a list of his contacts who have a video option wherein all entities in the individual user's video calling group will be displayed on a viewable table and each video option table entry will be associated with a routing table which contains the terminal type and selection number of the terminating subscriber, a Class of Service code which identifies the terminal type and options; and to send the Class of Service code to the 4G network which is forwarded to the terminating terminal in an “alternate caller ID” which tells the terminating terminal to set up terminal parameters matching those of the originating terminal, to support streaming video and audio on the full duplex basis and to enable an alternate ring tone, wherein the alternate ring tone is unique to the video service and message displayed on fixed terminal screens; and to answer the video call either in a mode which allows the terminating terminal to send video and sound or alternately in another mode in which the terminating terminal sends sound along with a “canned” video frame which informs that the called subscriber has opted out of the video send mode.
