A generation method of a circular training sequence containing two training symbols includes: randomly growing a first information clock with the length of N, copying the last L data before the first information block as the circulation prefix of the first training symbol, forming the first information block to the information block of the second training symbol in the same length with the first information block in terms of the circulation mode, namely, the second information block, in which, the circulation mode is to shift the last d data of the first block to the start position and copy the last L data of the second block before the second block as the training prefix of the second training symbol, so that the two symbols form a circulation training sequence.

The embodiment of the present invention provides a method and device for synchronizing video network resources to Internet terminals, which relate to the technical field of video networking. At the decompression transfer terminal, receive the Internet-of-Vision resource synchronization request sent by the Internet terminal based on the Internet protocol; the synchronization request includes: the identification of the co-translation server; the co-translation server stores a video-network resource compression package; The target co-conversion server corresponding to the co-translation server identifier forwards the Internet of Vision resource synchronization request; receives the resource compression package of each Internet of Vision corresponding to the Internet of Vision resource synchronization request returned by the target co-translation server; After receiving the resource compression package, decompress each video network resource compression package and synchronize it to the database. Synchronization failures due to long reception times can be avoided.

The invention discloses a processing method and a system of synchronization failure in dynamic content distributing (DCD) service. A series of error status codes defined in advance are stored in a terminal. When the synchronization between the terminal and a DCD server fails, the terminal reports a corresponding error status code to the DCD server according to a failure reason; then the DCD server carries out processing according to the failure reason expressed by the error status code, and when the failure reason is an temporary error, the DCD server informs the terminal to immediately attempt synchronization so as to avoid that a synchronous process of a normal retry mechanism delays the time of data synchronization, and thereby, user experience can be influenced. Correspondingly, when the failure reason is a fatal error, the DCD server sends a fatal error message to inform the terminal to let a user terminate synchronization so as to avoid that the synchronization triggered by the retry mechanism continuously fails, and thereby, an information interactive condition between the server and a client side can be improved. Meanwhile, the invention also discloses a processing system of synchronization failure in DCD service.
