说明：  Owing to the broad application value of audio watermarking in remote transmission and mobile extraction, it is very important to study watermarking approaches against A/D and D/A conversion. Based on wavelet decomposition and cepstrum technology, an audio watermarking algorithm is proposed where the low-frequency wavelet coefficients are chosen for cepstrum transforming. Then, the obtained cepstrum data shows stable for watermark hiding by the methods of edging data cutting and statistical mean modification. The synchronization is not required in the algorithm. Experimental results show that the proposed algorithm can resist on the attack of A/D and D/A successfully with features of large capacity and zero bit error. It will be helpful for the mobile audio in secure broadcast and management in the

In the TCP/IP protocol suite, TCP is the intermediate layer between IP below it, and an application above it. Using TCP, applications on networked hosts can establish reliable connections to one another. The protocol guarantees in-order delivery of data from the sender to the receiver Streams of data called segments are used by TCP peers to speak to each other. The segments can be quite large, so TCP breaks up the segments into smaller units of data. These units are encapsulated in the TCP packet that is passed to the IP protocol. Each unit of data is assigned a sequence number, which becomes part of the TCP packet. At the receiving end, the TCP module uses the sequence numbers in the packet to reconstruct the user data in the correct order.
