How to find the NVD-35 MARK II on an IP network

By default, once the physical connections have been made, the NVD-35
MARK II will try to obtain an IP Address from a DHCP network server. As

we will see this can be changed later to a Static IP address if required.

How to use the NVD-35 MARK II IP Finder Utility Software

Datavideo supply a free, Windows based utility, called NVD & NVP IP Finder.
The utility is also available for download on the product page of the official
website.

The first time this software is used on the computer you may need to allow it
permission through your computers firewall / anti-virus software in order for it
to be able to scan or search the local network.

When the utility scans the LAN that the computer is connected to, it displays
the current IP address for any NVD-35 MARK II units found on this local IP
network. Double clicking on the device listed will automatically open your
computers default web browser and navigate to the login page of the NVD-35
MARK II. If you are using an Apple computer then you can use an alternative
utility app such as Fing or Network Analyzer Lite.

NVD-35 MARK II

Settings > Display Setup

By default the NVD-35 MARK II will output video over the digital SDI port at a
resolution of 720P 50 fps and YUV colourspace.

Please note: The set resolution is only applied when the stream is decoding,
the device will output your monitors preferred resolution as it boots.

Output To

Here you can select to output video digitally over SDI or over the SD analogue
composite connection.

SDI (Digital)

When digital is selected you can select a screen resolution from SD
PAL/NTSC right up to HD 1080P60/50. The NVD-35 MARK II will scale your
source video to match the output resolution however the aspect ratio (4:3 or
16:9) should be matched to avoid black space on the output, for optimal
performance match the output resolution to the source video. The colour
space can be switched between YUV (YCbCr) and RGB, most video
equipment will use the YUV colour space however if the colors appear wrong
on your display please try RGB.

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.

15

Network Video Decoder

NVD-35 MARK II

Rotate / Flip

Provides the option to rotate or flip (mirror) the video output, default is off.

Settings > Network Setup

By default the NVD-35 MARK II will obtain its IP address automatically from a
DHCP server.

If you intend to use the NVD-35 MARK II 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.

Proxy

Here you can set the NVD-35 MARK II to connect to the internet via a proxy
server. Proxy server is also a way to bypass a firewall if there is one. Simply
enter the proxy IP and the port number as depicted below.

16

Network Video Decoder

Time

By default, the NVD-35 MARK II will synchronize its internal clock with public
NTP servers, if your network does not allow connections to external server
you can specify your internal NTP servers here. It is important the internal
clock is correct for secure HTTPS:// stream sources to work.

NVD-35 MARK II

Security

Here you can enable the internal telnet server, this is used so that the NVD-35
MARK II can be controlled by third party applications using socket commands.
Please see the socket commands section of this manual for more information.

17

Network Video Decoder

NVD-35 MARK II

Settings > Live Stream Setup

From this page you can configure the source stream for the decoder. The
NVD-35 MARK II supports the following stream types:

 RTSP over UDP (Unicast / Multicast)
 RTSP over TCP
 RTSP over HTTP
 SRT (Secure Reliable Transport) caller
 MPEG-TS over UDP
 RTMP Pull
 RTMP Push (Internal Server)
 UDP raw (Unicast/Multicast)
 HLS over HTTP
 MPEG-TS over TCP Pull

Decoder Mode
Default mode should be used for decoding standard streams from encoders

such as SRT, RTSP, RTMP, HTTP etc.
Selecting the RTMP Server (Internal) mode automatically generates an

RTMP URL and a stream key which should be entered into the corresponding
fields on Datavideo NVS devices or any other video streaming encoders.

The RTMP playback URL can be used to distribute the stream to multiple
other decoders, the number of concurrent RTMP clients is limited only by the
100Mbps ethernet port.

Video Sharing & HLS mode should be used for decoding from supported

18

Network Video Decoder

video sharing websites, such as:

NVD-35 MARK II

 Dailymotion
 Livestream
 Twitch
 UStream
 YouTube Live


Please see the check the product page on the datavideo.info website for a full
list of supported video sharing websites.

This mode also supports HLS streams, unlike Default mode you can select
the resolution of the stream you wish to decode if the HLS stream contains
multiple variants.

Input Stream

Enter the URL for the source stream here
Example for Default mode:

rtsp://192.168.1.50/stream1
rtmp://192.168.1.50/live/stream1
srt://192.168.1.50:9000

Example for Video Sharing & HLS mode:

https://www.youtube.com/watch?v=y60wDzZt8yg

Example for RTMP server mode:
rtmp://192.168.2.16:1935/stream/stream

Buffer Size

This determines how much video is buffered before playback starts, the
default 0.3 seconds should be suitable for streaming over Ethernet but a
larger buffer may be required in environments with poor network stability to
achieve smooth video when streaming over the internet or WiFi. If you notice
the video stuttering or the audio breaking up you should increase the buffer
size.

Note: You might experience long delay if the buffer size is too big.
RTSP protocol

Only displayed if a RTSP stream is being used, the transport protocol can be
manually specified.

SRT Latency

Only displayed if a SRT stream is being used. Secure Reliable Transport (SRT)

19

Network Video Decoder

achieves high-quality, low latency streaming across unreliable Internet
connections via UDP packets. If packets are lost in transit to the NVD-35
MARK II, a request to retransmit the lost packets is sent back to encoder. You
can adjust the latency to improve the Quality of Service (QoS) of the stream
and reduce the number of dropped packets. You can add from 20 ms to 8000
ms of latency to the SRT stream. Increasing latency gives more time to buffer
packets and resend any that got lost in transit to the destination. If the latency
value set for the stream is too low and there is packet loss over the network,
retransmission of lost packets will not be possible, and the stream quality will
suffer.

SRT Passphrase

If the SRT stream is encrypted, you must enter the passphrase here to
decode the stream.

Decoding video from the NVS-33/35/40 encoder

To decode video from the NVS the NVD-35 MARK II must be on the same
local network (Ethernet/WiFi) or be able to access the NVS stream over the
internet.

When the NVS is in RTSP TCP/UDP mode

Simply copy the RTSP URL from the ‘Live’ tab of the NVS and enter it into the
‘Input Stream’ field on the NVD-35 MARK II. When streaming over LAN it is

recommended to set the NVS in RTSP (TCP/UDP) mode.

When the NVS is in RTMP mode Local server mode

Simply copy the RTMP URL from the ‘Live’ tab of the NVS and enter it into the
‘Input Stream’ field on the NVD-35 MARK II

When the NVS-33/35/40 is in HLS mode

Simply copy the HLS URL from the ‘Live’ tab of the NVS and enter it into the
‘Input Stream’ field on the NVD-35 MARK II

Please Note: When in HLS mode, the buffer size should be set to 1.0
seconds or higher, if you notice audio artifacts you should increase the buffer
size.

Decoding a RTMP push stream

NVD-35 MARK II

To decode a RTMP push stream, first set the decoder mode to RTMP Server
(Internal) which should automatically generate an RTMP URL and a stream
key. Simply enter the RTMP URL and stream key into the corresponding fields

20

Network Video Decoder

NVD-35 MARK II

on Datavideo NVS devices or any other video streaming encoders.

Decoding other stream types

To decode other stream types such as UDP multicast or TCP, simply enter the
stream URL into the ‘Input Stream’ field of the NVD-35 MARK II.

Port Forwarding on your firewall / router

So that an NVS-33/35/40 video stream can be seen on the internet (beyond

the default gateway) certain network related ‘ports’ should be opened on your

router or firewall. Your local network administrator or I.T. support should be
able to help you with this.

Enable the “port forwarding” function or open below ports within the router
settings.
