Mapping layout for digital communication system

接收机接收数字信号，该信号包含一帧稳健VSB数据和ATSC数据的帧，还包含映射。该映射含有指示稳健VSB数据与ATSC数据在帧中位置的信息。接收机的译码器译码该数字信号。接收机的处理器根据该映射包含的位置信息，处理稳健VSB数据与ATSC数据中的至少一个。 A receiver receives a digital signal. The digital signal contains a frame of robust VSB data and ATSC data, and the digital signal further contains a map. The map contains information indicating a location of the robust VSB data and ATSC data in the frame. A decoder of the receiver decodes the digital signal. A processor of the receiver processes at least one of the robust VSB data and the ATSC data according to the location information contained in the map.
