The forth part introduces the serial to parallel and parallel to serial converse circuit. The byte synchronization is also fabricated in the chip. 第四部分介绍了系统的串并及并串转换电路。最后,串并转换电路完成串行-并行转换和字节同步。
The new point of this method is using automatic synchronization byte to implement automatic synchronization in watermark extraction. Use beginning-flags to present the begin place of the watermark, and ending-flags to present the end place and to validate the integrity of the watermark information. 该方法的创新点为:采用自同步字节实现水印提取的自动同步,采用前标识标志水印信息的起始位置,采用后标识标志水印信息的结束并验证水印信息的完整性。
