Abstract

"APARELHO, MéTODO E SISTEMA PARA CONFERêNCIA DE áUDIO E VìDEO E TELEFONIA SEM FIO". Um aparelho de acesso ao vídeo sem fio (101, 201, 301) e um vídeo-fone sem fio (120) prepara-se para teleconferência de áudio e vídeo e telefonia através de um primeiro canal de comunicações (103) possuindo comunicação com uma rede (140), tal como rede telefónica comutada pública ou uma rede ISDN. Uma configuração do aparelho de acesso ao vídeo sem fio (301) inclui uma interface de rede (210) acoplável a um primeiro canal de comunicação para recepção de um primeiro sinal de protocolo para formar um sinal de protocolo recebido e para transmissão de um segundo sinal de protocolo para formar um segundo sinal de protocolo transmitido; em modulador de freq³ência de rádio (270) para converter um sinal de vídeo de saída de faixa base em um sinal de vídeo de saída de freq³ência de rádio; um transmissor de freq³ência de rádio (273) acoplado a um modulador de freq³ência de rádio para transmitir um sinal de vídeo de saída de freq³ência de rádio; um receptor de freq³ência de rádio (277) para receber um sinal de vídeo de entrada de freq³ência de rádio; um desmodulador de freq³ência de rádio (275) acoplado ao receptor de freq³ência de rádio para converter o sinal de vídeo de entrada de freq³ência de rádio em um sinal de vídeo de entrada de faixa base; uma interface do usuário (215, 255) para recepção de um primeiro sinal de controle de uma pluralidade de sinais de controle; e um arranjo processador (190) sensível, através de um conjunto de instruções de programa, e em resposta ao primeiro sinal de controle, para converter o sinal de protocolo recebido ao sinal de vídeo de saída de faixa base e a um sinal de áudio de saída, o arranjo processador também sensível a converter o sinal de vídeo de entrada de faixa base e o sinal de áudio de entrada ao sequndo sinal de protocolo."AUDIO AND VIDEO CONFERENCE AND WIRELESS CONFERENCE SYSTEM, METHOD AND SYSTEM". A wireless video access apparatus (101, 201, 301) and a wireless video handset (120) prepare for audio and video teleconferencing and telephony over a first communications channel (103) having communication with a network 140 such as a public switched telephone network or an ISDN network. A configuration of the wireless video access device (301) includes a network interface (210) coupled to a first communication channel for receiving a first protocol signal to form a received protocol signal and for transmitting a second signal. protocol to form a second transmitted protocol signal; a radio frequency modulator (270) for converting a baseband output video signal to a radio frequency output video signal; a radio frequency transmitter (273) coupled to a radio frequency modulator for transmitting a radio frequency output video signal; a radio frequency receiver (277) for receiving a radio frequency input video signal; a radio frequency demodulator (275) coupled to the radio frequency receiver for converting the radio frequency input video signal to a baseband input video signal; a user interface (215, 255) for receiving a first control signal from a plurality of control signals; and a sensitive processor arrangement (190), by means of a program instruction set, and in response to the first control signal, for converting the received protocol signal to the baseband output video signal and an audio signal of output, the processor arrangement is also responsive to converting the baseband input video signal and the input audio signal to the protocol signal sequence.
