Abstract

The utility model discloses an image splicing device possessing the video recording and playing function. The image splicing device includes a video input module, a splicing processing module, and a video output module. The image splicing device also includes a data exchange module arranged between the video input module and the splicing processing module and a data storage module which is in mapping connection with the data exchange module. The beneficial effects are that the video splicing, recording and playing are integrated into one device, so the device cost is greatly reduced, and the signal attenuation and distortion caused by signal interconnection are reduced; at the same time, the integration enhances the system stability and reduces the device maintenance cost.

Description

A kind of image mosaic device with video recorded broadcast function

Technical field

The utility model relates to a kind of image mosaic device with video recorded broadcast function, belongs to technical field of video processing.

Background technology

In the demonstration fields such as image display splicing wall, video wall, requirement can be carried out real-time recording, playback to view data more and more.Traditional realization often needs the equipment (splicer+video recorded broadcast equipment) of two platform independent in conjunction with finishing this function, its flow chart of data processing is such, at first video source is exported to video record equipment and video montaging device simultaneously, recording arrangement is finished the compression storage of video, and splicer is realized splicing, the stack special effect processing of video; Secondly, when system needs playback video, need to access the video of wanting playback from recording arrangement, be transferred to splicer, output to video wall by splicer again.

Obviously, so process and increased system cost, the video reception module that recording arrangement and splicer have function to approach, data-signal is processed through different receiver modules simultaneously, can reduce picture quality, and the interconnection of distinct device has also increased system complexity, bring risk for whole system stability, complicated apparatus interconnection reaches the functional redundancy between distinct device simultaneously, all brings unsteadiness and the maintenance cost of unnecessary cost output, increase system to whole system.

Summary of the invention

The purpose of this utility model is to provide a kind of image mosaic device with video recorded broadcast function, can be implemented in to carry out video-splicing and video recorded broadcast in the same equipment, reduces equipment cost.

The purpose of this utility model is achieved through the following technical solutions: a kind of image mosaic device with video recorded broadcast function, comprise video input module, splicing processing module and video output module, it also comprises video input module and the data memory module that splices the data exchange module between the processing module and dock with the data exchange module mapping.

Described data exchange module is matrix switcher.

Connect by high-speed bus between described video input module, data exchange module, data memory module, splicing processing module and the video output module.

The beneficial effect of the utility model method is: video-splicing and recorded broadcast are integrated in the equipment, greatly saved equipment cost, the signal attenuation that signal interconnection brings, distortion have been reduced, the integrated stability of a system that strengthened simultaneously, the cost of equipment maintenance that has reduced.

Description of drawings

Fig. 1 is system schematic of the present utility model.

Wherein, the 1-video input module, the 2-data exchange module, the 3-data memory module, 4-splices processing module, 5-video output module.

Embodiment

Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.

Such as Fig. 1, a kind of image mosaic device with video recorded broadcast function, comprise video input module 1, splicing processing module 4 and video output module 5, it also comprises video input module 1 and the data memory module 3 that splices the data exchange module 2 between the processing module 4 and dock with data exchange module 2 mappings.

Described data exchange module 2 is matrix switcher.

Connect by high-speed bus between described video input module 1, data exchange module 2, data memory module 3, splicing processing module 4 and the video output module 5.

Wherein, video input module 1 is mainly finished video signal collective, and the unlike signal source signals such as VGA, DVI, CVBS, YCbCr, HDMI are gathered, and converts the high-speed serial data of 3G to, gives data exchange module;

Data exchange module 2 can shine upon the multipath high-speed serial data to different data reception modules (data memory module, splicing processing module etc.);

Data memory module 3 is mainly finished reception, compression, the storage of vision signal, simultaneously the reading of supported data, decompress(ion), transmission;

Splice processing module 4 and mainly finish the special video effects processing such as the splicing of vision signal, stack, and the signal after will processing sends to the video output module;

Video output module 5 is mainly finished reception and the conversion of vision signal, the vision signal that receives is converted to the video format outputs such as VGA, DVI, CVBS, YCbCr, HDMI.

Flow chart of data processing of the present utility model is as follows:

A, video data send to splicing processing module 4 and data memory module 3 from video input module 1 through data exchange module 2;

B, splicing processing module 4 are processed the concatenation of video, give video output module 5 with the result, finally are presented on the combination to show;

The video data of c, data memory module 3 Real Time Compression storage input is finished the video record process;

D, when needing playback video in system, access the video data that will check from data memory module 3, give splicing processing module 4 through data exchange module 2 with video data transmitting, splicing processing module 4 handling processes are with step b.
