Ovideo releases UXGA HD video coding terminal based on H.264 standard
Committed to high performance digital media experience, providing leading embedded audio and video solutions Suppliers AVST companies (BEIJING AVSOLUTION TECHNOLOGY Co., Ltd. launched the latest product of the first Aurora product line, new full HD AURORA HD video coding terminal AUR8200AC and Recording terminal AUR8210AC.
Video System (PC-graphic-system) and graphics system (PC-graphic-system), which belonged to two different applications, with their own acquisition equipment, storage devices, display devices, and transmission devices, but with the Internet in consumption The popularity of the market and the industry, the video and graphics systems begin to fuse, and the computer's display and flat-screen TV are equipped with components, HDMI and VGA interfaces. They can also support TV system and VESA formats; flash memory, hard drives and HD DVDs have also become Mainstream storage device; short-range HDMI cable, VGA cable and DVI cable, long-distance Ethernet also become the transmission and interconnection standards of mainstream video and graphics signals. Another significant trend is that video and graphics devices are in higher resolution, higher frame rate, higher per pixel depth and higher dimensional development.
The figure below shows the proportion and type of video system and graphics system resolution:
In order to record and transmit high-resolution video information and computer graphics information, there is a need for a video encoding device to collect, compress, transmit, and store video signals and computer graphics signals, thereby completing the source to file, source to the network. Basic functions, which requires the collection, compression, storage, and transmission of video encoding devices. The performance of the four modules must meet the needs of HD video applications.
Aurora product line of Ovideo can simultaneously support TV system and VESA formats. It is a high-performance, including acquisition, compression, storage, and transmission of four core modules including collection, compression, storage, and transfer in the 1/2 standard chassis width and 1U height. Embedded audio and video device. It is worth mentioning that the overall power consumption of the product is only 4-8W, all materials are in line with RoHS standards, which is a true energy-saving and environmentally friendly product.
The acquisition module has adopted the industry's highest performance video-specific analog-to-digital conversion chip and color format decoding chip, and the powerful software system can fully intelligently identify support including 1080p, 1080i, 720p, 576p, 480p, 576i, and 480i. Most VESA systems, including UXGA, WXGA, SXGA, XGA, and VGA, in order to get a better compression effect, the module also supports de-interlace for 576i / 480i / 1080i format, go Noise (DE-NOISE) and Down-Scale), provide a high quality image for subsequent compression engines.
The following table shows the video and graphic input format list supported by the Aurora product line:
The compression engine, using the on-board system architecture of the programmable digital signal processor core and the hardware accelerator macro unit, can achieve 1600 × 1200 @ 30 Hz and 1920 × 1080 @ 30fps H.264 under the premise of power consumption and flexibility HP real-time video compression performance, compression algorithm adopts the current most advanced video compression standard H.264-HP (High-profile), which is higher than H.264-BP (Baseline-Profile) and H.264-MP (Main-Profile) Higher grade compression criteria supports more encoding tool sets, allowing higher compression efficiency, fundamentally solving the transmission of high-definition video mass data and storage bottlenecks. The engine also supports 8-96K sampling two-channel AAC audio encoding, and users can choose a lower complexity AAC-LC encoder or 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, and the advantage of adding the hard disk is that the terminal can record the high-definition video information collected independently without the network connection or remote viewing requirements, and the storage software can put The audio and video file is recorded to the standard .mp4 file format container and supports the user-set file naming and auto-distribution.
The transmission system supports Gigabit Ethernet interface (Gig-Interface), which can work in 1000/100 / 10Mbps adaptive mode, media stream supports standard RTSP protocols with H.264 and AAC payload, convenient and PC The RTSP player is interconnected, for the built-in hard disk product, the user can even directly access the video file list recorded in the hard disk, and watch the video file directly in the browser, and can download the files interested in FTP.
The Aurora product line of Ovitish has a wide market application prospect, which can be applied to the information on the computer screen to do real-time records and network transmission, such as financial systems, online conferences, digital trials, distance teaching, medical care, radar. System, etc.
