Overview

Purpose

As part of its strategy to measure audience viewing of content on consumer devices,
Nielsen supports or endorses a variety of products that generate Nielsen ID3 tags and
insert them into segmented MPEG-2 transport streams or into MPEG-DASH containers.
The Nielsen Validator application (referred to as "Validator") is a diagnostic tool that
analyzes Nielsen ID3 tags and helps in troubleshooting problems with applications that
generate such tags.
These are six principal ways to use Validator:
•
Process a transport stream (TS) with embedded Nielsen ID3 tags (option –t)
•
Process an HLS stream with the m3u8 index and transport segments zipped into a
file (option –m)
•
Process a file of encrypted ID3 tags such as the output of the PCM-to-ID3 SDK
sample application or the log file of a mobile device that processes Nielsen ID3 tags
(option –r)
•
Process specific MPEG-DASH segments in a folder, guided by the user's command-
line instructions, to guarantee that the segments are processed in the proper order
(-dr option – this is the preferred method of processing MPEG-DASH content)
•
Process a set of MPEG-DASH segments that have been merged into a single file
(option –d)
•
Process all MPEG-DASH segments in a specific folder that end with a user-defined
extension (option–df)
This manual explains how to use Validator as a diagnostic tool. It focuses on the testing
and debugging of applications that use the PCM-to-ID3 SDK to generate Nielsen ID3
tags. It describes issues that commonly arise during the integration process and how to
resolve them.
In addition, developers who create applications based on the Nielsen ID3 Tag Validator
SDK can use Validator prior to sending their test files for transcoder certification.
