1.2 Features and Benefits
The Video server is a cutting-edge digital video transmission device. It can
compress and transmit two channels of real time images with outstanding
images quality (D1, 720x480) at reasonable bandwidth through a standard
TCP/IP network. This video server also provide two-way audio streams
along with each video channel. That’s because it is Ethernet ready and has
the powerful ARM9 SoC and the MPEG-4 compression ASIC inside. In
addition, with these powerful hardware platform, excellent SDK support
and powerful respective apparatuses (eg. the transcoder), this Video server
is your best choice building up either conventional IP surveillance system or
intelligent IP surveillance system.

Real-time MPEG-4 Compression
With hardware MPEG-4 compression chip inside, the composite video
inputs can be efficiently compressed into MPEG-4 bit stream without
any delay. The ASIC base compression engine can support not only
CIF, but also FULL D1 image resolution.
z
QoS Enabled Video Streaming
For real-time video streaming requirements, the Video server
implemented the 802.1pQ features inside the SoC as the streaming
engine to make sure the video streaming package is forwarded faster
than normal TCP/UDP packet.
z
Automatic Frame Rate Control
The Video server supports automatic/manual streaming frame rate
control, especially for multiple clients concurrent access the same
video stream in different network bandwidth.
z
Digital Time Code Embedded
The “Digital Time Code Embedded” function is to embed the
recording time in the MPEG bit stream. Therefore, each image frame
has its respective time when it was recorded. It is very useful when
users want to find the video at an exact time or between a certain time
intervals.
z
Build-in Low Latency PPPoE Supported
The Ethernet port is equipped with a low latency PPPoE
(Point-to-Point over Ethernet) which has excellent transmission speed
and enables the Video server to connect to an ADSL or a cable
