Abstract

QUE COMPRENDE: a) MULTIPLES UNIDADES RECEPTORAS QUE RECIBEN SENAL DE DIFUSION DIGITAL TERRESTRES DE MULTIPLES CANALES, Y SELECCIONA UN CANAL DE LOS MULTIPLES CANALES PARA GENERAR UNA SENAL DE TS; b) UNA PRIMERA UNIDAD DE MULTIPLEXION Y TRANSMISION QUE INGRESA CADA SENAL DE TS GENERADA POR (a), MULTIPLEXA CADA SENAL DE TS, Y GENERA UNA SENAL DE FLUJO MULTIPLEXADA PARA SER TRANSFERIDA; c) UNA SEGUNDA UNIDAD DE MULTIPLEXION Y TRANSMISION QUE INGRESA LA SENAL DE FLUJO MULTIPLEXADA TRANSFERIDA POR (b), Y QUE SEPARA CADA SENAL DE TS ORIGINAL; Y, d) UNA UNIDAD TRANSMISORA QUE ASIGNA DE MANERA INDEPENDIENTE CADA SENAL DE TS SEPARADA POR (c) PARA CADA SEGMENTO CONFIGURANDO UNA SENAL PARA SER RETRANSMITIDA RESPECTIVAMENTE, DETERMINANDO UN PATRON DE MARCO DE MULTIPLEXION CON UN PARAMETRO DE SENAL DE TRANSFERENCIA OBTENIDO AL UNIFICAR LAS SENALES DE TS ASIGNADAS, RE-MULTIPLEXANDO USANDO EL PATRON DE MARCO DE MULTIPLEXION PARA COMBINAR TODAS LAS SENALES DE TS, Y TRANSMITIENDO LAS SENALES COMBINADAS COMO LA SENAL QUE VA A SER RETRANSMITIDA. (b) ENCAPSULA EN IP LA SENAL DE FLUJO MULTIPLEXADA GENERADA, Y TRANSMITE UN PAQUETE DE IP A TRAVES DE UNA RED DE IP A (c); Y (c) RECIBE EL PAQUETE DE IP DESDE (b) Y DESENCAPSULA DE IP EL PAQUETE DE IP PARA SEPARAR CADA SENAL DE TS ORIGINAL. LA SENAL DE DIFUSION DIGITAL INCLUYE UNA SENAL DE DIFUSION DE TELEVISION DIGITAL TERRESTRE Y UNA SENAL DE DIFUSION DE VOZ DIGITAL TERRESTREWHICH INCLUDES: a) MULTIPLE RECEIVING UNITS THAT RECEIVE TERRESTRIAL DIGITAL BROADCAST SIGNAL FROM MULTIPLE CHANNELS, AND SELECT ONE CHANNEL FROM THE MULTIPLE CHANNELS TO GENERATE A SIGNAL FROM TS; b) A FIRST MULTIPLEXING AND TRANSMISSION UNIT THAT ENTERS EACH SIGNAL OF TS GENERATED BY (a), MULTIPLEXES EACH SIGNAL OF TS, AND GENERATES A MULTIPLEXED FLOW SIGNAL TO BE TRANSFERRED; c) A SECOND MULTIPLEXING AND TRANSMISSION UNIT THAT ENTERS THE MULTIPLEXED FLOW SIGNAL TRANSFERRED BY (b), AND THAT SEPARATES EACH SIGNAL FROM THE ORIGINAL TS; AND, d) A TRANSMITTER UNIT THAT INDEPENDENTLY ASSIGNES EACH SIGNAL OF TS SEPARATED BY (c) FOR EACH SEGMENT CONFIGURING A SIGNAL TO BE RETRANSMITTED RESPECTIVELY, DETERMINING A MULTIPLEXION FRAME PATTERN WITH A PARAMETER OF THE TRANSMITTING OBJECTS OF SENAL. ASSIGNED TS SIGNALS, RE-MULTIPLEXING USING THE MULTIPLEXING FRAME PATTERN TO COMBINE ALL TS SIGNALS, AND TRANSMITTING THE COMBINED SIGNALS AS THE SIGNAL TO BE RETRANSMITTED. (b) ENCAPSULATES THE GENERATED MULTIPLEXED FLOW SIGNAL IN IP, AND TRANSMITS AN IP PACKET THROUGH AN IP NETWORK A (c); AND (c) RECEIVES THE IP PACKET FROM (b) AND DEENCAPSULES THE IP PACKAGE TO SEPARATE EACH ORIGINAL TS SIGNAL. THE DIGITAL BROADCAST SIGNAL INCLUDES A DIGITAL TERRESTRIAL TELEVISION BROADCAST SIGNAL AND A DIGITAL LAND VOICE BROADCAST SIGNAL
