| 摘 要： | 电子节目指南(EPG)作为数字多媒体广播的一种数据业务,在DAB中被广泛使用。而随着DAB节目的丰富,EPG内容增加。受传输速率的限制,传统EPG结构使其内容的解码显示影响到了用户的体验。针对DAB电子节目指南的内容、结构及其作用,提出一种可以快速获取EPG必要内容的业务说明信息(PI)结构方案,并论证了方案的可行性。

| Abstract: | As a data service in digital multimedia broadcasting,Electronic Program Guide(EPG) is widely used in DAB.With the DAB program becoming richer,EPG content is increased.Limited by the transmission rate,the structure of traditional EPG decoder make its decoding display of the content affect the user's experience.Aiming at the DAB electronic program guide content,structure and function,a Program Information(PI) structure scheme is put forward which can quickly obtain the necessary content of EPG,and the feasibi... |
