系统架构 1.2.1 System Architecture
u FPGA + architecture
Based on the high-stability and high-bandwidth FPGA pure hardware architecture, the hardware design of the functional modular board is used to realize the infinitely expanding FPGA + architecture.
u Modular card design
The main modules such as input board, output board, switch board, matrix board, fan, power supply, and dust filter are all card-type design, which brings great convenience to daily use and maintenance.
u Expansion slot supports random mixing of input and output boards
u Supports group management of up to 4 groups of display walls, and supports multiple groups of display layouts with different resolutions and stitching modes; signal sharing between each group of screens is convenient for user management.
u Output mapping
The construction site is more flexible, and there is no need for one-to-one correspondence between the connection wires between the equipment and the display unit, which can be adjusted at any time in the software.
视频图像处理 1.2.2 Video image processing
u Intelligent scaling technology, image scaling uses intelligent multi-phase filtering algorithm, automatically selects the optimal filter coefficient according to the characteristics of the image, the image is close to the magnitude of the zoom effect, ensuring more details, no jagged edges and good sharpness.
u Supports multiple ultra-high resolution basemaps
u Supports multiple vector-level subtitles, as well as dynamic rolling subtitles and static subtitles. You can arbitrarily edit the display content, font, color and other parameters.
u Supports AI-level image one-click processing engine, adopts artificial intelligence-level image processing technology, can realize one-click fill light, one-click defog and other intelligent image processing.
u Supports seamless switching. The processor integrates a high-definition signal processing mechanism to ensure that there is no delay, no blue screen, no black screen and other intermediate transition states when the signal is switched.
u Support intelligent real-time processing functions such as intelligent black removal (arbitrary cropping of the input image), edge blending, and area enlargement.
u Supports any cross-screen, window opening, roaming, overlay, and zoom functions of the picture; supports single-layer four-screen separate cascade and layout at most.
u Supports the character overlay function of the input signal. You can change the font type, size, background color, foreground color, display position and other parameters through the control software.
u Supports automatic detection of input signals, real-time detection of whether each input port has signal access, input board and client software have status indicators.
u Support matrix switching, integrated matrix function inside the processor, support all input signals to switch to all output ports at will.
网络及多媒体处理技术 1.2.3 Network and Multimedia Processing Technology
u IP stream real-time decoding, support H.265
u Supports ONVIF, RTSP and other network streaming media protocols, compatible with mainstream IPCs, NVRs, video streaming media servers, etc .; a single network port supports up to 64 D1, 32 720P, 16 1080P, 4 4K decoding .
u Support information release on screen
u Video, picture, digital title, scroll banner release, electronic clock, real-time weather and other controls are displayed, and graphic information is edited independently to meet the information release on screen of various display devices.
u Built-in playback system, supporting various media formats (optional)
u Supports almost all videos (rmvb, avi, mpeg, dat, mov, mkv, wmv, etc.), audio (mp3, wma, wav, etc.), pictures (jpg, gif, png, etc.); supports streaming TV, video capture , Support PDF, office documents, dynamic web pages, weather, time, rolling captions, etc.
u Other value-added features
u Supports redundant power supplies, one for normal use and one for backup. When normal power fails, it will automatically switch to standby power.
u Support BS control / Support cross-platform control (optional)
No need to install any client software, support web login control; support various operating systems such as windows, IOS, MAC OS, Android, Linux and cross-platform control.
u Support intelligent temperature control, the processor detects its internal temperature in real time, and automatically controls the fan switch.
Supports pre-operation mode. After enabling this function, all window operations will not take effect immediately. You need to click confirm to make all operations effective at once.
It is suitable for multi-signal input of display equipment, multiple outputs with splicing windows (single screen 4 windows) and playback, and splicing applications for multimedia information distribution. It is used in the fields of security monitoring, broadcast television, video conference, command center, media multifunctional hall Ideal for multi-screen display.
