Abstract
<B>APARELHO DE VIDEOFONE, PROCESSO E SISTEMA PARA TELEFONIA E CONFERêNCIA POR áUDIO E VìDEO COM LINHA DE FIOS<D>. Um aparelho (110, 150) de acesso de vídeo proporciona teleconferência de áudio e vídeo e telefonia através de um primeiro canal (103) de comunicação tendo comunicação com uma rede (140), tal como a rede telefónica pública comutada ou uma rede ISDN. O aparelho (110) de acesso de vídeo inclui uma interface (210) de rede de linha de fios; um modulador/desmodulador (205) de freq³ência de rádio; uma interface de usuário (215); e um arranjo de processador (190). Um aparelho de videofone (700, 800) é acoplável a um aparelho de acesso de vídeo através de um segundo canal de comunicação para recepção e transmissão de vídeo, e através de um terceiro canal de comunicação para recepção e transmissão de áudio. O aparelho de videofone inclui um monitor de vídeo (715), uma interface de câmera (235), uma câmera de vídeo (720), e um módulo telefónico (710). Múltiplos aparelhos de videofone (700, 800) podem ser usados simultaneamente, e múltiplos sinais de vídeo a partir dos aparelhos de videofone (700, 800) podem ser multiplexados e combinados em um sinal de vídeo composto para transmissão para a rede (140).<B> VIDEOPHONE APPLIANCE, PROCESS AND SYSTEM FOR TELEPHONY AND CONFERENCE BY AUDIO AND VIDEO WITH WIRELESS LINE <D>. A video access apparatus (110, 150) provides audio and video teleconferencing and telephony via a first communication channel (103) having communication with a network (140), such as the public switched telephone network or an ISDN network. The video access apparatus (110) includes a wired network interface (210); a radio frequency modulator / demodulator (205); a user interface (215); and a processor arrangement (190). A videophone device (700, 800) is coupled to a video access device via a second communication channel for receiving and transmitting video, and through a third communication channel for receiving and transmitting audio. The videophone apparatus includes a video monitor (715), a camera interface (235), a video camera (720), and a telephone module (710). Multiple videophone devices (700, 800) can be used simultaneously, and multiple video signals from the videophone devices (700, 800) can be multiplexed and combined into a composite video signal for transmission to the network (140).
