Abstract

"SISTEMA, TRANSMISSOR E RECEPTOR DE RADIODIFUSãO DIGITAL, E, MéTODO DE RADIODIFUSãO DIGITAL PARA TRANSMITIR UMA CORRENTE DE TRANSPORTE COMO RADIODIFUSãO DIGITAL TERRESTRE". Um programa constituido de uma série de eventos é transmitido como uma corrente de transporte de uma estação de radiodifusão (10) e recebido por um receptor (100). A estação de radiodifusão (10) transmite a informação de enlace que representa a relação de enlace entre a corrente de transporte, o programa ou os eventos a serem transmitidos para uma área de serviço (10a) da mesma e o programa a ser transmitido para uma area de serviço adjacente (20a) após a soma do mesmo à corrente de transporte. Como resultado disso, o receptor (100) pode, mesmo quando se moveu da área de serviço (10a) para a área de serviço adjacente (20a), receber o programa transmitido para a área de serviço adjacente (20a) de forma contínua com referência à informação de enlace.
