The video system (Television-Video-System) and the graphics system (PC-Graphic-System) are originally divided into two different application areas, with their own collection devices, storage devices, display devices and transmission devices, but with the Internet in consumption With the popularity of the market and industry, video and graphics systems are beginning to merge. Computer monitors and flat-panel TVs are equipped with components, HDMI and VGA interfaces, and can support TV and VESA formats; flash, hard drives and HD DVDs have also become Mainstream storage devices; short-range HDMI cables, VGA cables and DVI cables, long-haul Ethernet has also become the mainstream standard for transmission and interconnection of video and graphics signals. Another significant trend is that video and graphics devices are moving toward higher resolutions, higher frame rates, higher bit depth per pixel and higher dimensionality.

The following figure shows the ratio and type of resolution of the video system and graphics system:

In order to record and transmit high-resolution video information and computer graphics information, a video encoding device is required to collect, compress, transmit and store video signals and computer graphics signals, thereby completing the source to the file, the source to the network. The basic functions, which require the acquisition, compression, storage and transmission of the video encoding device, must meet the requirements of high-definition video applications.

Ovid's AuroraTM product line supports both TV and VESA standards. It is a high-performance integrated system that integrates acquisition, compression, storage and transmission in a 1/2 standard chassis width and 1U height. Embedded audio and video equipment. It is worth mentioning that the overall power consumption of the product is only 4-8W, and all materials are in compliance with RoHS standards. It is a real energy-saving and environmentally friendly product.

The acquisition module uses the industry's highest performance video-specific analog-to-digital conversion chip and color format decoding chip. With powerful software system, it can fully intelligently and automatically recognize and support all including 1080P, 1080I, 720P, 576P, 480P, 576I and 480I. TV system and most VESA systems including UXGA, WXGA, SXGA, XGA and VGA, in order to get better compression, the module also supports De-Interlace for 576i/480i/1080i format. Processing such as De-Noise and Down-Scale provides high quality images for subsequent compression engines.

The following table provides a list of video and graphics input formats supported by the AuroraTM product line:

The compression engine uses a system-on-a-chip architecture with a programmable digital signal processor core and a hardware accelerator macrocell to achieve H.264 with 1600×1200@30Hz and 1920×1080@30fps with both power consumption and flexibility. HP real-time video compression performance, the compression algorithm uses the most advanced video compression standard H.264-HP (High-Profile), which is better than H.264-BP (Baseline-Profile) and H.264-MP (Main-Profile) The higher-grade compression standard supports more coding toolsets, which can achieve higher compression efficiency and fundamentally solve the transmission and storage bottleneck of high-definition video massive data. The engine also supports 8-channel AAC audio encoding with 8-96K sampling, allowing users to choose a lower complexity AAC-LC encoder or a higher performance AAC-HE encoder.

The storage system fully supports the 2.5-inch hard disk and electronic disk of the high-speed SATA-II interface. The advantage of adding the hard disk is that the terminal can independently record the collected high-definition video information without network connection or remote viewing requirements, and the storage software can Audio and video files are recorded in the standard .mp4 file format container, and user-defined file naming and automatic volume sharing functions are supported.


Transmission system, support Gigabit Ethernet interface (GigE-Interface), can work in 1000/100/10Mbps adaptive mode, media stream supports standard RTSP protocol with H.264 and AAC payload, which can be convenient and more than PC RTSP player interconnection, for the built-in hard disk products, users can even use the browser to access the list of video files recorded in the hard disk, and directly watch the video files in the browser, and also download the files of interest through Ftp.

Ovid's AuroraTM product line has broad market applications and can be used in applications where real-time recording and network transmission of information on a computer screen is required, such as financial systems, web conferencing, digital trials, distance learning, medical monitoring, radar System, etc.

The following image shows a typical application model for AuroraTM products:

AVST's new generation AuroraTM product line transmission products AUR8200AC, AUR4200AC, AUR2200AC are currently sampling to qualified customers, using a compact 1U high 1/4 rack wide industrial design, using external adapter 12VDC power supply, power consumption is only 4-8W .

Industrial Gigabit Ethernet Switch is an Industrial Fast Ethernet Switch with 6 ports, supporting six 10/100BASE-T ports.
industrial Gigabit Ethernet Switch series is packaged in a compact IP40 case that allows either DIN rail or panel mounting for efficient usage of cabinet space.
Without power and wires, can power supply for HD IP Camera, wireless AP, IP phone and so on.
