A WIRELESS MULTI TRANSMITTING AND RECEIVING APPARATUS FOR MULTIMEDIA EDUCATION

机译:一种用于无线多媒体教学的无线收发装置

摘要

PURPOSE: A wireless multiple transmitting/receiving device for a multi-media education is provided to execute different education to each education object simultaneously by simultaneously transmitting education programs of a plurality of multi media education devices to a plurality of education objects by wireless. CONSTITUTION: An input unit(38) is connected to a plurality of education devices and is inputted wanted education programs. A plurality of channel exchangers(11) perform a mapping of video and voice data of the education programs to wanted channel. A plurality of voice synthesizers(13) synthesize a voice inputted from the education devices and a lecturer's voice inputted from the exterior. An UHF signal converter(15) converts a plurality of image signals and voice signals inputted from the channel exchangers(11) and the voice synthesizers(13) into UHF signals having different frequencies. A plurality of amplifiers(17) amplifier the plurality of UHF signals converted in the UHF signal converter(15), respectively. A plurality of antennas(19) transmit the signal amplified in the amplifiers(17), respectively. A plurality of receivers(20) receive the signal transmitted from the antennas(19) and execute a program of wanted channel according to a class or a group.
