AI 中文摘要
巴西的DTV系统标准近期已修订，以应对与广播服务和宽带服务深度融合相关的新用例。这种演进不能扰乱当前的DTV服务，因为巴西及许多ISDB-T国家仍处于从模拟向数字转换的过程中。中间件层是这种渐进（但强大）演进的最佳候选。对于作为基于接收机配置文件的开放平台的巴西DTV中间件Ginga而言，成果令人印象深刻。本文聚焦于由巴西DTV论坛在学术界主导的合作下完成的Ginga DTV接收机D-Profile规范所解决的进展及新用例。
英文摘要
The Brazilian DTV system standards have been recently revised in order to address new use cases related to deeper integration be- tween broadcast services and broadband services. Such an evolution could not disrupt the current DTV services since Brazil and many ISDB-T countries are still under the switch-off process from ana- log to digital. The middleware layer is the best candidate for such an incremental (yet powerful) evolution. In the case of Ginga, the Brazilian DTV middleware, as an open platform based on receiver profiles, the results were impressive. In this paper, we focus on the advances and new use cases addressed by the D-profile Ginga DTV receiver specification carried out in the Brazilian DTV Forum under a collaborative effort led by the Academia
