40results about How to "Reduce data flow" patented technology

A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and / or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

A storage server for efficiently retrieving data from a plurality of disks in response to user access requests. The server comprises a plurality of processors coupled to disjoint subsets of disks, and a custom non-blocking packet switch for routing data from the processors to users. By tightly coupling the processors to disks and employing an application-specific switch, congestion and disk scheduling bottlenecks are minimized. By making efficient use of bandwidth, the architecture is also capable of receiving real-time data streams from a remote source and distributing these data streams to requesting users. The architecture is particularly well suited to video-on-demand systems in which a video server stores a library of movies and users submit requests to view particular movies.

The invention discloses a method of using multicast PIM protocol message to obtain device port information, including the steps: 1) as IP protocol module of a route device supporting PIM multicast protocol receives the PIM protocol message, it directly adds physical port information for receiving the message to the message and reports the message with the port information to a PIM protocol processing module for processing; 2) the PIM protocol processing module receives the message, and then takes the port information out of it; 3) the PIM protocol processing module uses the port information to build a corresponding relationship between port and neighbor; and 4) the PIM protocol realizes the transmission of multicast data according to the corresponding relationship. It is simple to implement, good in extensibility and compatibility, and unnecessary to modify the interface between original modules, thus making the software easy to implement on a platform and it reduces the coupling factor between different modules and then enhances the robustness and maintainability of the software.

The invention relates to the field of ultrasonic medical images, in particular to an ultrasonic elastic imaging system implemented through an FPGA and a working method of the ultrasonic elastic imaging system. The system comprises a front end ultrasonic digital signal obtaining module, a middle end ultrasonic elastic imaging real-time processing module and a rear end elastic image display module. The system has the advantages that nuclear elastic imaging signal processing is completed through the FPGA, elastic images are displayed in real time, front end ultrasonic data do not need to be transmitted to an upper computer, and therefore the system is simplified, and the cost performance of the product is improved.

The invention discloses a data communication method and equipment capable of relieving transmission burden. The data communication method of the equipment comprises the following steps: identifying anequipment type; identifying and screening the communication data according to the equipment type; and sending the processed communication data to a third party. The communication data can be effectively identified and screened, thereby relieving the transmission burden and avoiding the subsequent data obesity.

The automatic synchronization method for data of intelligent business system comprises: building data chain between SMAP and SMP; acquiring SCP information list for business control; determining the source and target node lists by SMAP; acquiring information list from SMP; and synchronizing every target node. This invention can reduce maintenance workload.

The invention discloses a method and system for remote on-board troubleshooting and repair. When a vehicle malfunction alarms, it is confirmed whether to enter the troubleshooting mode; after entering the troubleshooting mode, when the vehicle is in a safe environment, it enters the set troubleshooting work At the same time, according to the current fault information, the working condition data of the corresponding system on the vehicle is collected; after the fault troubleshooting is completed, combined with the working condition data, fault maintenance suggestions are given remotely, and on-site fault repairs are carried out according to the maintenance suggestions. The remote fault diagnosis method of the present invention is more direct and efficient. The corresponding acquisition module is awakened according to the fault code information, which greatly reduces the data flow, and prompts the driver to enter a specific fault reproduction working condition, which can quickly find problems, reduce the amount of data, and effectively avoid data redundancy. Residual and data loss risks, to achieve the purpose of rapid troubleshooting and analysis of faults.

The invention discloses a method for implementing an HTTP message caching mechanism based on keywords. The method comprises the following steps: matching an HTTP request message of a client with a corresponding configuration item; and searching the request message of the client according to the keywords in the configuration item, and determining whether to give an HTTP response to the user from a cache or to acquire a complete HTTP response from a server or to acquire a partial HTTP response from the server and modify the cached message according to the configuration so as to compose a complete HTTP response. By using the method provided by the invention, data traffic between a proxy server and a WEB server is effectively reduced; latency for the client to access a WEB page is effectively shortened; the WEB page requested by the client each time can be ensured to be the updated page; the effects of reducing the data traffic and shortening the latency of the WEB page related to the user status and browser type at the client can also be achieved; and the cache of the WEB page can be optimized according to configuration files.
