The product was developed using embedded systems network video encoder.It adopted a functional super sound, video encoding chips, to be collected from the cameras, microphones and other equipment in the analog video.Audio Signalusers can set up the export of high-quality compression served as a high compression ratio of MPEG1/2/4 video format video and digital audio stream.multicast transmission through the Internet and technology to achieve high-quality long-distance radio-level sound and video transmission.The products provide transparent data access can be achieved for remote control operation of various equipment.It also provides a multi-channel alarm input and built-in alarm function campaign.The products are high resolution images, colored, low-latency and synchronization of audio and video outstanding advantages, such as good.to include distance learning, tele-medicine and other high-quality radio and television monitoring requirements of digital video applications.Main features -- using embedded systems.high stability supports Ethernet interface

-- Interface -- oil/E1 high resolution 720X576 image.adjusted downward -- better real-time MPEG2 codec total delay time of less than 300ms.the total delay time of 200ms

-- MPEG4 video codec.Audio support transparent synchronous data transmission

-- good (422/485 adjustable) -- both alarm signal input and output

-- both switch or remote network equipment through the serial port for configuration support -- Unicast,

-- Broadcast and Multicast broadcast transmission quality, FULL D1

-- high-performance real-time coding.cost

-- easy to install, simple to use

-- to provide complete,Since the definition of a convenient development tool

-- OSD function

--9 different regional campaign

-- audio alarm installed options,saving bandwidth

-- to support a fixed rate and variable bit rate

-- two-way audio codec

-- built four pictures switching device 475, one video input feature

-- the way video loop can be shown then choose coding of video

-- optional MPEG1/2/4 video encoder format one of the encoded output

-- with the condition of the network to choose the most explicit video format

-- the condition of the network adaptive rate guarantee high-quality image quality indicators video characteristics -- Video bitrate 256k-10M bps

-- Video output modes :fixed rate / variable rate system /NTSC PAL switching system -- Video resolution PAL :720*576,480*576,352*576 NTSC : 720*480.

-- 480*480,352*480 --GOP Adjustable brightness, contrast, saturation,

-- Adjustable input color format : MPEG1/2/4 served as a flow of the TS.
