A data synchronization method for more than three networked devices including at least one client and one server for efficiently synchronizing data among multiple devices supporting a Synchronization Markup Language (SyncML) protocol is provided. The data synchronization method includes determining whether a data item indicated by synchronization information contained in a synchronization request message exists in a change log table of the server, when a server receives the synchronization request message sent by a first client, and updating the change log table by adding the data item indicated by the synchronization information and transmitting a synchronization request message containing a data identifier and the change log of the data item to a second client, if a data item indicated by the synchronization information does not exist, otherwise, ending data synchronization by transmitting a synchronization response message containing status information to the first client.

Pixels extracted from each of an input video signal are thinned out in units of predetermined samples, and the thinned out samples are fetched in equal order frame by frame and mapped into active periods of first, second, third, and fourth sub-images conformable to the HD-SDI format. The mapped first, second, third, and fourth sub-images are each separated into a first-link transmission channel and a second-link transmission channel, and are thus mapped into eight channels. The mapped first, second, third, and fourth sub-images are converted in parallel. Parallel digital data items into which the sub-images are converted in parallel are then outputted.

The embodiment of the invention discloses a data synchronization method, a data synchronization terminal and a data synchronization system. The method comprises the following steps of: acquiring synchronous data selected by a user; encapsulating the synchronous data into a specified data format, wherein the specified data format is the data format used for encapsulating and decapsulating the synchronous data between equipment which perform the data synchronization; and transmitting the encapsulated synchronous data to target equipment, wherein the target equipment is the equipment serving as a synchronous data receiving end in the equipment which perform the data synchronization. By the adoption of the method, the terminal and the system, the data synchronization among pieces of user equipment can be realized conveniently and quickly.

The invention discloses a method and system for fast synchronization of table items. The method for fast synchronization of table items includes: first step, the user sends the table item to the CPU of the main control board; second step, the CPU of the main control board passes through the The out-of-band channel between the boards sends the entry to the service board CPU; the third step, the main control board CPU sends the table item to the service board NP processor through the inter-board in-band channel; the fourth step, the service board CPU passes the inter-board The out-of-band channel asynchronously receives entries to the local database of the service board, and at the same time, the NP processor of the service board synchronously receives the entries through the off-board channel. The present invention introduces the mode of asynchronously receiving entries by the CPU of the service board, so that the CPU of the service board releases the current receiving and processing task in a shorter time to perform the next receiving and processing. In addition, after receiving the table items, they only need to be synchronized to the database of the board, and do not need to be sent to the NP processor of the board through the PCIe channel on the board, which simplifies the processing process and releases more CPU resources.

An audio processing apparatus and a control method thereof are provided. The method includes receiving an audio signal including audio data corresponding to each of a plurality of channels, generating a strobe signal for the audio data corresponding to each of the plurality of channels, converting a clock for the strobe signal corresponding to each of the plurality of channels to a master clock having preset multiple speeds, and outputting the audio signal based on the master clock. The simplification of the system configuration is accomplished by synchronizing an input and an output of the audio signal using hardware.

The invention relates to the technical field of communication, in particular to a synchronous frame capturing method and a synchronous frame capturing device. The synchronous frame capturing method includes: starting from the first codon, separating a preset amount of codons into a plurality of assumed single frames by a preset single-frame codon length; sequentially extracting the codons at the ith bit from the assumed single frames, wherein the i is not smaller than zero and not larger than the value obtained by subtracting one from the single-frame codon length; ranking the extracted codons according to a sequential extraction order so as to obtain assumed synchronous frames; comparing the assumed synchronous frames with a target sequence in a step-by-step dislocation manner; if one section of continuous codon fields in the assumed synchronous frames is identical to the target sequence, determining the current ith bit as a synchronization bit for the single frames, determining the continuous codon fields as codons of a synchronous sequence of the synchronous frames, and determining the first one of the single frames and the starting frame of multiframes according to the first one in the continuous codon fields. The synchronous frame capturing method and the synchronous frame capturing device have the advantages that synchronization of the multiframes is finished in one step, a process for synchronization of the multiframes is simplified, and the time for synchronization of the multiframes is shortened.
