Abstract

"SISTEMA E MéTODO PARA A DIFUSãO DE SINAIS CODIFICADOS INDEPENDENTEMENTE EM CANAIS ATSC". O padrão ATSC para difusão de televisão digital especifica um Canal de Dados em adição aos canais normais de áudio e vídeo. uma metodologia é fornecida para utilizar o Canal de dados ATSC para difundir correntes de vídeo MPEG-4, para as quais um novo serviço de vídeo é criado. As correntes MPEG-4 podem ser encapsuladas em pacotes MPEG-2PES (Correntes Elementares Empacotadas) ou diretamente em pacotes de transporte MPEG-2. Esse mecanismo permite a difusão sincronizada de correntes MPEG-4 para um sistema de TV digital ATSC sem uma mudança no padrão ATSC quando da difusão de dados. Em um sistema de transmissão de informação de vídeo e áudio, no qual o sistema é restrito a operar de acordo com um padrão determinado, incluindo a aplicação de uma determinada metodologia de codificação, a transmissão de informação utilizando uma metodologia de codificação que é independente da metodologia de codificação é fornecida através da codificação da informação em uma pluralidade de incrementos (310) codificados de acordo com a metodologia de codificação independente; e encapsulando os incrementos de informação codificados em uma parte de carga útil (324) dos pacotes de transmissão estabelecidos de acordo com o padrão determinado."SYSTEM AND METHOD FOR DIFFUSION OF INDEPENDENTLY CODED SIGNALS IN ATSC CHANNELS". The ATSC standard for digital television broadcasting specifies a Data Channel in addition to normal audio and video channels. A methodology is provided to use the ATSC Data Channel to broadcast MPEG-4 video streams, for which a new video service is created. MPEG-4 chains can be encapsulated in MPEG-2PES (Packaged Elementary Chains) packets or directly in MPEG-2 transport packets. This mechanism allows synchronized broadcasting of MPEG-4 streams to an ATSC digital TV system without a change in the ATSC standard when broadcasting data. In a video and audio information transmission system, where the system is restricted to operate according to a given standard, including the application of a particular coding methodology, the transmission of information using a coding methodology that is independent of the coding methodology is provided by coding the information in a plurality of coded increments (310) according to the independent coding methodology; and encapsulating the encoded information increments in a payload portion (324) of the transmission packets established according to the given standard.
