1) Introduction

 

This wiki page lists the V&V Test Bitstreams, Source Material and Tools created and/or used by TM-NIP.

V&V stream definition: TM-NIP0125r10 V&V WP4 Test Stream Description

 

2) Live On-Air Test Streams 

SES ASTRA DVB-NIP Test Streams are broadcast using DVB-S2X GSE-Lite (Generic Stream Encapsulation) HEM (High Efficiency Mode)

Eutelsat NIP Test Streams are broadcast using MPE (Multi-Protocol Encapsulation) inside MPEG-2 Transport Stream Services.

2.1) SES ASTRA

 

The following DVB-NIP Test Streams are currently on air on SES ASTRA 19.2E:

2.1.1 Transponder Parameters

 

Please note that Transponder 1.037 was switched off at 18h00 on the 9th November and was replaced by Transponder 1.102. Content remained identical.

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/quick_start_guide_dvb_nip_analyzer-01.00.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):

 

https://dvb-vandv.s3.eu-west-2.amazonaws.com/dvb-nip/DVB-NIP-analyzer/dvb-nip-analyzer-1.0.32.zip

 

(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

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
