1.2 Features and benefits
The video transcoder is a high resolution, Ethernet (LAN and WAN) ready
digital video transcoder. Via an Ethernet network such as LAN or WAN,
the video transcoder takes a MPEG-4 stream from our IP camera or video
server, and converts it in real-time with high quality analog video signals.
This allows analog video devices such as TV system, analog monitors or
existing analog video switches to be connected to our IP-base surveillance
video system.
z
Up to full D1 MPEG-4 video decoding
The video transcoder can convert network MPEG-4 stream into analog
video signals. It also can automatically detect the remote stream format,
resolution and video standards. With ASIC based hardware decoder
inside, this video transcoder is capable of decoding video at full frame
rate (30/25 fps). The analog video resolution of more than 500 TV
lines (depends on quality of video source)
z
Supports regular TV sysytem and analog monitors
The video transcoder does not support composite video only, it also
supports Y/C video output. This feature allows analog video devices
such as regular TV sets, analog monitors and existing analog video
switches to be connected to our IP surveillance video system.
z
QoS Enabled (L2,L3) Video Streaming (Unicast/Multicast)
For real-time video streaming requirements, the video transcoder
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
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 LAN and WAN (Low Latency PPPoE Supported) Ports
The video transcoder provides two RJ-45 connectors. One is WAN and
the other is LAN. The WAN port connects to the internet and LAN
port connects to the local network. Since the internet’s bandwidth is
