Abstract

"INTERFACE DE PROGRAMAçãO DE APLICAçãO PARA HABILITAR O ACESSO DE INFORMAçõES DE SISTEMA DE UM FORMATO ABSTRATO POR UM RECEPTOR DE TELEVISãO DIGITAL" Uma interface de programação de aplicação (API) permite que aplicações (por exemplo, códigos applets) de um terminal de televisão digital recuperem as Informações de Sistema (SI) de um fluxo de transporte digital sem considerar o formato específico das SI. A API abstrai as porções relevantes da SI a fim de prover a mesma em um formato genérico, utilizável. O sistema é adequado para uso, por exemplo, com os formatos SI que incluem as Informações Específicas de Programa MPEG (PSI), DVB, SI, o Protocolo de Programa AISC e de Informações de Sistema (PSIP), SI a cabo, como, por exemplo, o Padrão de Vídeo Digital 234, e as SI privadas. Em uma modalidade opcional, a emissão assíncrona das SI é provida para as SI não imediatamente disponíveis na memória do terminal. Além disso, a API pode ainda abstrair as SI de modo a torná-las independentes do formato de fluxo de transporte específico (por exemplo, MPEG-2). Além disso, a recuperação incremental dos dados de SI é provida ao permitir uma aplicação de modo a se obter um subconjunto pequeno das SI disponíveis no terminal, analisar as mesmas, e recuperar as SI adicionais se necessário com base na análise. A API inclui uma embalagem de navegação (110), uma embalagem de guia de programa (120), uma embalagem de seleção / sintonia de programa (130), uma embalagem de descritor (140), uma embalagem de utilidade (150), uma embalagem de dados (160), e uma embalagem de pipeline (170)."APPLICATION PROGRAMMING INTERFACE TO ENABLE THE ACCESS OF SYSTEM INFORMATION FROM AN ABSTRACT FORMAT BY A DIGITAL TELEVISION RECEIVER" An application programming interface (API) allows applications (for example, applet codes) from a digital television terminal retrieve the System Information (SI) from a digital transport stream without regard to the specific format of the SI. The API abstracts the relevant portions of the SI in order to provide it in a generic, usable format. The system is suitable for use, for example, with SI formats that include MPEG Program Specific Information (PSI), DVB, SI, the AISC Program and System Information Protocol (PSIP), Cable SI, such as, for example, the Digital Video Standard 234, and private IS. In an optional mode, the asynchronous transmission of the SI is provided for the SI not immediately available in the terminal's memory. In addition, the API can also abstract the SIs to make them independent of the specific transport flow format (for example, MPEG-2). In addition, incremental recovery of SI data is provided by allowing an application to obtain a small subset of the SI available at the terminal, analyze them, and recover additional SI if necessary based on the analysis. The API includes a navigation package (110), a program guide package (120), a program selection / tuning package (130), a descriptor package (140), a utility package (150), a data pack (160), and a pipeline pack (170).
