摘要:
Frames comprise odd fields and even fields. The frame sync segments of the odd fields contains a current map specifying the location of data in frames, a next map specifying the location of data in a future frame, and a frame count designating the future frame. The frame sync segments of the even field may contain the same information. Alternatively, the frame sync segments of the odd fields contain the current map and part of the frame count, and the frame sync segments of the corresponding even fields contain the next map and the rest of the frame count. A receiver uses the map and frame count information to find data in the fields of received frames.
摘要(中):
帧包括奇数场和偶数场。 奇数场的帧同步段包含指定数据在帧中的位置的当前映射,指定未来帧中的数据的位置的下一个映射以及指定未来帧的帧计数。 偶数场的帧同步段可以包含相同的信息。 或者,奇数场的帧同步段包含当前映射和帧计数的一部分,并且相应偶数场的帧同步段包含下一个映射,并且剩余的帧计数。 接收机使用地图和帧计数信息来查找接收帧的字段中的数据。
