4) NIP Tools

4.0) SES DVB-NIP Analyzer

The SES DVB-NIP Analyzer provides a full Analysis Suite for the entire DVB-NIP Specification in the latest Revision: r4. It can work as both a live and offline Analyzer.

It includes a tree explorer that allows analyzing all DVB-NIP defined metadata documents and all AV content provided. It provides detailed bitrate analysis of the various elements in a DVB-NIP Stream 

It also features a test suite with Excel export:

and an XML Validator.

The SES DVB-NIP Analyzer accepts as input: PCAP files, TS files and allows interfacing with the Inverto Q-Stream receivers for live stream analysis.

A quick start guide is available under the following link:

https://dvb-vandv.s3.eu-west-2.amazonaws.com/dvb-nip/DVB-NIP-analyzer/dvb-nip-analyzer-guide.pdf

The SES DVB-NIP Analyzer is available as a docker image:

sessystems/dvb-nip-analyzer - Docker Image | Docker Hub

or as a MS Windows executable (statically compiled: no need to install it, simply run the file):

SES DVB NIP Analyzer for MS Windows Version 1.1.28

(Versions above 1.0.21 of the Analyzer are aligned with NIP schema version 4.1)

4.6) Offline testing procedure using a local DEKTEC modulator

With the help of a Dektec modulator, it is possible to generate DVB-NIP compliant RF streams in the lab without access to a live satellite signal

4.6.1 Compatible Modulators from Dektec

• DTU-315 USB-3 General-Purpose Modulator
• DTA-2115(B) PCIExpress All-Standard Modulator

4.6.2 Setup

Description:

A firmware update of the above devices is not necessary only the latest version of the StreamXpress application.

After selecting the S2X-GSE-Lite HEM modulation and Normal FEC Frame in StreamXpress, one can specify the symbol rate, modulation parameters and select a PCAP input file.

The modulated output will be a DVB-NIP compliant stream.

4.7) Playing back captured pcap files for re-creating live NIP streams

With the help of tcpreplay it is possible to playback pcap files to re-create IP-layer live NIP streams

4.7.1 tcpreplay

Included in most package repositories for Linux

sudo apt-get install -y tcpreplay

if not available, here is the link to the download site:

https://tcpreplay.appneta.com/

4.7.2 Setup

Description:

tcpreplay -i lo /live_capture_1_231016.pcap
