<P>PROBLEM TO BE SOLVED: To provide an adaptor for video-audio transmission/reception which transmits and receives large-capacity video data and audio signal data in real time between two portable terminals. <P>SOLUTION: A first video-audio transmission/reception adaptor analog-digital converts large-capacity video data signal and audio data signal received from a transmission mobile terminal, compresses them and so on and transmits them to a first wireless communication module. The first wireless communication module encodes, modulates and packetizes the received large-capacity video data signal and audio data signal, and then transmits the packet signal to a second wireless communication module in real time via a next generation high-speed wireless communication line and a network. The second wireless communication module demodulates and decodes the received large-capacity video data signal and audio data signal, and transmits them to a second video-audio transmission/reception adaptor. The second video-audio transmission/reception adaptor decodes and expands the received large-capacity video data signal and audio data signal and then transmits them to a destination mobile terminal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
