The basic characteristic of the video matrix

Video matrix is one of the most important feature is the video image from any one input channel switch to display any one output channel. In general, a M * N matrix: said it can support both M image input and N road image output. There needs to be emphasized is must to do any, or any one input and any one output.

A matrix systems usually should also include the following basic functions: character signal superposition; Yuntai decoder interface to control and camera; Alarm interface; Control the host, as well as audio control box, alarm interface box, control the keyboard, etc.

Now often say the video matrix, its implementation, video switch in the analog signal layer video signal switching control analog switch by the controller, we call this the analog video matrix.

Digital video matrix

Digital video matrix, first of all, should have the basic features of the above video matrix, has the basic function of the video matrix. But it is different from analog video matrix, first is digital, analog video signal switching in the digital video signal layer is completed, this is the essence of the difference between digital video matrix and analog video matrix.

Digital video matrix, there are two typical types: one is based on bus digital video switching, we referred to as the main line video matrix. Is a kind of digital video switching based on IP packet, we called packet switching type digital video matrix.

Any of the DVR on the market at present, it is a special case of general linear digital video matrix: there is only one video output. The DVR for multi-channel video input, also has the function of image segmentation.

Introduction to digital video matrix

The core of the digital video matrix is introduced hikvision DS4002MD card, namely matrix decoding card, the card in the realization of digital video matrix at the same time, also has the function of hardware decoding.

Based on the MD card digital video matrix form

Digital video matrix of the video input source

Through video compression card (HC) input analog video signal;

Through the real-time video streaming network access;

Stored in the local video files.

After the two cases is the use of MD card hardware decoding functions, the compressed video decoding, and as a source of video input into matrix.

The video output of digital video matrix

Analog video output each DS4002MD support 2 road, at the same time each video output supports multiple Windows image segmentation, image to switch the video matrix is an unit with the window.

Application, for example,

By MD 64 DVR card and audio compression card system and 64 x 4 real-time video matrix, in this system, can use hikvision HC card 64 PC - DVR system, at the same time use 2 pieces of MD four-way analog output card is complete, realize real-time video of 64 x 4 matrix function.

Digital video matrix of 64 * 4 + real-time video system

Composed of MD network matrix, the scenario consists of 16 pieces of DS4002MD 64 road decoding system, support 32 channel analog video output at the same time, through the different image segmentation, can form a variety of flexible video output.

Network remote can use hikvision H - DVR card, HC card of PC, also can use the embedded DVR, DVS hikvision.

The advantages and features of digital video matrix solution

Cost advantage

Just a PC card and MD can form a small video matrix system. Equipment of low cost, convenient installation, commissioning, integration, strong stability, high maintenance cost is low.

Performance advantage

Powerful, flexible configuration, all functions are based on PC platform, can by the user through the application of arbitrary configuration. Using MD card and cooperate with the audio compression card, you can at the same time realize the DVR, video matrix, image segmentation, hardware decoding four big functions.

Rich image processing functions

The matrix of the output resolution of 4 cif, image quality can be guaranteed;

Each channel video output can be custom image segmentation methods, have picture in picture function, and can output the user custom image; \

Several common ways of image segmentation

Image switch speed is quick, the picture is fluent, strictly synchronous switching process, no frame, no dislocation;

What you see is what you get, the content of the matrix of output and video content of DVR system.

Analog video matrix system development is already very mature at present, the structure and function of its products in recent years, no big changes, can excavate potential is limited. The digital matrix is completely different, with the rapid increase of the level of software and hardware, there is reason to believe that the digital matrix have a broad space for development, whether in the overall performance or will inevitably on the function more than analog matrix
