Step D, by matrix, view data is decoded, image is outputed on large-size screen monitors to tiled display view picture picture.
In steps A as above, the quantity of picture segmentation depends on the quantity of large-size screen monitors, when user terminal order video, judges that there are several large-size screen monitors in this hall, terminal place.
In step B as above, video data after cutting apart is defined as to a synchrodata group, in group, comprises a plurality of packets, in synchronization group, establish a master data bag, the video packets of data of cutting apart the rear first via of take is master data bag, and each packet is used the common time to stab as data time.
Step C as above comprises the steps:
Step C1, the packet matrix device in route transfers to hall, the corresponding large-size screen monitors of matrix device, route prioritised transmission master data bag wherein, matrix device corresponding to master data bag is as principal matrix equipment, and remaining matrix device is from matrix device;
Packet outside step C2, master data bag is to principal matrix device registration, and under principal matrix equipment records, the packet of all master data bags association is as from packet;
Step C3, principal matrix are received from the registration of packet, upgrade cogradient matrix list.
Step D as above comprises the steps:
Step D1, principal matrix equipment carry out decode operation to master data bag, stab according to the playback rate of master data bag to send the current frame time that is about to output display from packet place from matrix device simultaneously;
Step D2, from packet place from matrix device to carrying out decode operation from packet, simultaneously according to the packet timestamp of receiving, in conjunction with self current video output situation, accelerate or abandon frame data, to reach the effect of simultaneous display output.
Compared with prior art, tool has the following advantages and effect in the present invention:
1, can pass through the same video pictures of multihead display, image is more displayed greatly more clearly, better meet the application scenario that needs high definition to show;
2, by precise synchronization, the output of the picture synchronization of all large-size screen monitors, has solved the latency issue causing because of various processing such as coding, transmission, decodings, and the image that large-size screen monitors are shown is coherent.
