Description
Technical field
The present invention relates to the control that display screen shows, be specifically related to synchronous flickering method of a kind of multiwindow frame and device.
Background technology
A lot of IP cameras is all supported the function that intrusion detection is reported to the police now, and in based on multicomputer multi-screen splicing processor system, relates to a lot of IP video displaying.IP video displaying, great majority all are the methods of the IP video window frame flicker of employing.But in based on multicomputer multi-screen splicing processor system, not being what same computing machine accomplished because multi-screen processor shows to play up, how this lets a plurality of computing machines accomplish the prompting process of flicker synchronously if just relating to.
Traditional method for synchronous is based on synchronization server; Need synchronous multicomputer multi-screen splicing processor node (node is exactly a computing machine); Transmit a request to synchronization server; Synchronization server is collected the request of all interdependent nodes, and synchronization server issues the respective synchronization signal then to processor node when the request of all nodes all arrives.Its core point is synchronization server.When window (processor node corresponding a plurality of windows) frame need show or hides; Node sends synchronization request to synchronization server; Synchronization server is collected the request of all window interdependent nodes; Ask to respond when all arriving the synchronization request of all nodes when all, node is accomplished the operation to window border.
The traditional scheme problem need to be extra synchronous service to come supporting frame to glimmer synchronously; When synchronization server is inoperable, cause all processor nodes all can not work normally; The advantage that can't represent distributed system influences the availability of total system; In addition because traditional scheme is based on the consideration of load aspect; Synchronous service needs the synchronization request of the uninterrupted processing multinode of handling (for example 100 nodes), a plurality of window (for example 16 windows), high-frequency (for example 25 times/second); The data interaction amount is very big (if 40 computing machines are arranged; Every computing machine has 16 windows, and the flicker frequency of each window is 25 times/S, then need carry out 40*16*2*25=32000 time information interaction); Stable new demand to the processing speed network of synchronous service is too high, and network jitter a little all has very big influence to synchronous effect.
