Abstract

"TRANSMISSãO DE VìDEO/áUDIO DIGITAL EM SISTEMAS CELULARES". Um método para proporcionar informação a uma pluralidade de dispositivos de comunicação móveis sem fio. O método inclui dedicar pelo menos um canal (306~ 1~) de uma pluralidade de canais (306) de dados de espectro difuso como um canal de difusão. A freq³ência e fase de um sinal de portadora e de um relógio (206) de taxa de circuito integrado do pelo menos um canal são sincronizadas para cada um de uma pluralidade de transmissores celulares (204) de uma pluralidade respectiva de estações de base (134). A informação e então transmitida através do pelo menos um canal dedicado a partir de cada estação de base.
