DCR Static VHL

Engineering Portal / Digital / DCR & DTVR / DCR Static VHL

Prerequisites

To get started, an App ID is needed. The App ID is a unique ID assigned to the player/site/app. This will be provided upon starting the integration.

'PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'

Implementation Steps

Add Tracking Code

Tracking Code Components

The tracking code includes

• Adobe VHL Library JS
• Create SDK Instance
• Setup Global Parameters
• SDK Initialization
• Content Metadata
• staticstart Event

The Adobe DCR Tracking Code must be added to each page.

<script src="script/lib/VideoHeartbeat.min.js"></script>

 // A second SDK instance must be created specifically for static, if video measurement is also enabled on the same page.
 var i = NOLSDK.getInstance('mynewinstance');

 //The Required Nielsen Global Parameters Must Be Established
 var _nolggGlobalParams = {
     apid: "PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX",
     sfcode: "dcr",
     nsdkv: "511",
     apn: "Static-VHL",
     nol_sdkDebug: "DEBUG"
 };
  
 //You Can Now Initialize The SDK While Passing The Global Parameters
 i.ggInitialize(_nolggGlobalParams);

  // Create Content Metadata Object
  var nielsenMetadata = {
    type: 'static', 
    assetid: '', // *DYNAMIC METADATA*: unique ID for each article **REQUIRED**
    section: '', // *DYNAMIC METADATA*: section of site **REQUIRED**
    segA: '', // *DYNAMIC METADATA*: custom segment
    segB: '', // *DYNAMIC METADATA*: custom segment
    segC: ''  // *DYNAMIC METADATA*: custom segment
    }; 
    
  // Event 'staticstart' Call
  i.ggPM("staticstart", nielsenMetadata);

Pass App ID in Initialization Call

Pass the unique App ID in the first parameter of the initialization call, <apid>.

Example SDK Initialization

var i = NOLSDK.getInstance('mynewinstance');
var _nolggGlobalParams = {
     apid: "PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX",
     sfcode: "dcr",
     nsdkv: "511",
     apn: "Static-VHL",
     nol_sdkDebug: "DEBUG"
 };
i.ggInitialize(_nolggGlobalParams);

The initialization call has five parameters:

Parameter	Description	Values
apid	Unique ID assigned to player/site.	PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX
sfcode	Nielsen Server Designation	'dcr'
nsdkv	Nielsen SDK version	'511'
apn	Name of App	Any string value
nol_sdkDebug: "debug"	Enables Nielsen console logging. Only required for testing	nol_sdkDebug: "debug"

Update <apid> with the AppID provided. Refer to the Going Live section to know about updating the AppID to production after testing is completed.

Configure Metadata

Map the Nielsen keys to variables so that the content metadata is dynamically updated.

The Nielsen reserved keys are:

Key	Description	Data Type	Value	Required?
type	asset type	fixed	'static'	Yes
assetid	Unique ID for each article	dynamic	custom (no Special Characters)	Yes
section	section of each site (e.g. section value should be first level in page URL: website.com/section). Limit to 25 unique values	dynamic	custom	Yes
segA	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No
segB	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No
segC	custom segment for reporting: Limit to 25 unique values across custom segments (segA + segB + segC)	dynamic	custom	No

The values passed through the Nielsen keys will determine the breakouts that are seen in reporting. The custom segments (A, B & C) will roll into the sub-brand. To not use custom segments A, B and C, do not pass any value in these keys.

Aggregation Limits There are limits on the number of unique values that can be aggregated on in reporting. The specific limitations by key are:

Key	Aggregation Limit
section	maximum of 25 unique values (section <= 25)
segA	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segB	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)
segC	Maximum number of unique values allowed across segA, segB, and segC is 25 (segA + segB + segC<= 25)

Opt-Out

The site must provide a means for the user to opt-out of, or opt back into, Nielsen Measurement. A user can opt-out if they would prefer not to participate in any Nielsen online measurement research. To implement the opt-out option, include the following two items in your privacy policy

• A notice that the player includes proprietary measurement software that allows users to contribute to market research (such as Nielsen TV Ratings)
• A link to the Nielsen Digital Measurement Privacy Policy at https://www.nielsen.com/digitalprivacy

On the Nielsen Digital Measurement Privacy Policy page, users can click Choices to read more detailed information about the measurement software, learn about their options with regard to Nielsen measurement, and, if they do not want to participate in Nielsen online measurement, click a link to receive an opt-out cookie.

The following paragraph is a template for an opt-out statement, the properties may feature Nielsen proprietary measurement software, which will allow users to contribute to market research, such as Nielsen TV Ratings. To learn more about the information that Nielsen software may collect and your choices with regard to it, please see the Nielsen Digital Measurement Privacy Policy at https://www.nielsen.com/digitalprivacy.

Opt Back In

Once users have opted-out, they can choose to opt back into Nielsen Measurement at anytime by selecting the opt back in link on the Nielsen Digital Privacy Policy page. When a user selects the link, their opt-out cookie will be deleted and they will be able to be measured.

Infinite Scrolling

onPaginate will refire the view ping with the existing/original metadata.

i.ggPM("onPaginate", scrolloffset);

Parameter	Description
event	onPaginate
scrolloffset	The scrolloffset value should be the y-scroll position:

onPaginate

onPageinate is a slightly modified version of staticstart to enable tracking of user’s focus in pages with continuous scrolling. onPaginate event provides the same behavior as staticstart keeping it local to only clients who wish to implement continuous scrolling. (Note: This event onPaginate will not reset the page duration timer.)

• The maximum number of static View pings allowed per session is ‘1’. This is enforced via the nol_maxPingCount parameter in the tag and the cadence of impression.
• When an onPaginate event is called at the end of section / a focus shift (within the same page), this filter will reset the current ping count to ‘0’ for the static View ping. This change of value will cause a new View ping when the Browser SDK receives the next staticPosition event (at the section end). This sequence continues through the end of scrolling or till the close of static page session.

Going Live

Once the DCR Tracking Code is added to the site, Nielsen will validate the implementation. Following Nielsen testing, users need to make a couple of updates to the initialization call to ensure that the site is being measured properly.

1. App ID: Ensure that correct <apid> is used during initialization

   'PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'
   

1. Debug Logging: Disable logging by deleting {nol_sdkDebug: 'DEBUG'} from initialization call.
   • Example Production Initialization Call - Refer to the production initialization call below:

var i = NOLSDK.getInstance('mynewinstance');
var _nolggGlobalParams = {
     apid: "PXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX",
     sfcode: "dcr",
     nsdkv: "511",
     apn: "Static-VHL"
 };
i.ggInitialize(_nolggGlobalParams);
