Network Video Decoder
NVD-20
Composite (Analogue)
When analogue is selected the UI will change and you can only select
between PAL and NTSC resolution with a 4:3 or 16:9 aspect ratio.
Settings > Network Setup
By default the NVD-20 will obtain its IP address automatically from a
DHCP server.
If you intend to use the NVD-20 directly connected to a PC or network
without a DCHP server then you should assign a manually set IP
address by selecting 'Static Configuration'.
We recommend that only advanced users who are aware of IP
addressing set the manual 'Static Configuration' IP address. Your local
network administrator or I.T. support may be able to help you with this.
