DCR & DTVR Browser Adobe Launch Extension
From Engineering Client Portal
Adobe Launch Extensions
Adobe Launch Extensions are building blocks for mobile application development that reside on Adobe Servers for client utilization.
Nielsen provides three Adobe Launch Extensions that can be integrated to an html page containing any number of video players. It allows clients to add the reporting functionality to their site by putting several lines of JavaScript code into the page.
- BDSK Adobe Launch Extension
- IMA Adobe Launch Extension
- VJS Adobe Launch Extension
Extension Installation and Configuration
Nielsen has developed Extensions to simplify adding Nielsen measurement into your video stream. The first step is to create and publish a property which is outlined in the Getting Started Guide.
Install the Extension
Nielsen provides three Adobe Launch Extensions that can be integrated to an html page containing any number of video players. It allows clients to add the reporting functionality to their site by putting several lines of JavaScript code into the page.
BSDK extension
BSDK extension integrates the Nielsen BSDK, initializes BSDK instances that can be used by any other extension or from the client’s page directly.
VJS (VideoJS) extension
VJS extension subscribes to standard media events fired by VideoJS player, processes data provided by the user and taken from player, and calls BSDK API (trackevent).
IMA extension
IMA extension subscribes to events fired by the IMA plugin, processes data provided by the user and taken from IMA, and calls BSDK API (trackEvent).
Build the Extension
After the Extension is configured, it can be “built” under the “library” on the Publishing page with other “libraries”.
Add a New library
Select to add a new library
Set the name, chose Environment (Production, Staging, Development):
Save and Build
Add all changed resources. When you get the Extension configured, it will appear in the list of changed resources. Select the Latest revision and press “Select & Create a New Revision” button:
Confirm
Once built, it will appear in the list of Development libraries:
Multi-instance support
The user’s page can contain several players. The user creates BSDK, VJS and IMA extension instances for each player. They should be bound by any string identifier, e.g. a player name. This value must be set in "sdk_instance_name" field of “ext_opt” object for all extensions to bind them.
Prerequisites
Before you begin, ensure that you have an Appid. This is a Unique ID assigned to the player/site and configured by product. If you do not have an AppID , please review the OnBoarding Guide.
BDSK Adobe Launch Extension
BSDK extension integrates the Nielsen BSDK, initializes BSDK instances that can be used by any other extension or from the client’s page directly. Users can communicate with the extension in two ways – either by calling functions exposed by the extension or by using events.
The following events and API calls are supported:
| Event | API Function | Description | |
|---|---|---|---|
| "nls-sdk-get-info" | window.NSDKAPI.getInfo | requests BSDK extension to provide the extension version information | |
| "nls-sdk-init-instance" | window.NSDKAPI.initInstance | requests BSDK extension to initialize a new SDK instance | |
| "nls-sdk-trackevent" | window.NSDKAPI.trackEvent | sends data for trackEvent function of the SDK |
Event based API
The extension listens to the following custom events:
"nls-sdk-get-info"
Format of input object is the following:
{ detail:
{
callback: function(obj) { /* Do something */}
}
}
All parameters and supported values are described below.
| Parameter | Description | Required | Values | |
|---|---|---|---|---|
callback |
Function that is called by the extension to provide output data | Yes | Function |
"nls-sdk-init-instance"
Format of input object is the following:
{ detail:
{
sdk_instance_name: <name>,
// other parameters,
callback: function(obj) { /* Do something */}
}
}
All parameters and supported values are described below.
| Parameter | Description | Required | Values | Example | |
|---|---|---|---|---|---|
| sdk_instance_name | Name of the BSDK instance. It's used to bind BSDK and other extensions. If it's not provided, the extension generates the name. It can be obtained in the callback function. |
No | string | "sdk_instance_name": "myPlayer1"
|
|
| debug | Debug flag. If set to "DEBUG", the extension prints debug messages to the browser console. |
No | string | "debug": "DEBUG"
|
|
| apid | APID that is used in Browser SDK | Yes | string | "apid": "PXXXXXXXX-XXXX-"

Tracking the SDK Event
Event Types
The following event types are supported:
| Key | Description |
|---|---|
| playhead |
It is used to pass content, ad or static metadata, the current playhead value, Unix timestamp or id3 payload, OTT information to the SDK. |
| pause |
This event should be used to in the following cases: application enters background, any application interruptions, content playback is paused. (Pause is detected by SDK automatically only if the time gap between commands exceeds 30 minutes.) |
| complete |
It is called when session is completed or ends. |
| adStop |
This event should be called at the end of each ad and is required when advertisements have the same assetId. |
Handling JSON Metadata
Parameter “data” is a JSON object with many key-value pairs that holds all information required by SDK.
Format of input object is the following:
{
"event": <event identifier>,
"type": <type of metadata>,
"metadata":{
"content": <content metadata object>,
"ad": <ad metadata object>,
"static": <static metadata object>
},
"playheadPosition":<playhead value | Unix Timestamp>,

Implementation Methods
There are two ways to communicate with extensions. Users can use events or call the extension methods directly.
Event Implementation Method
The first step is to include the following Inside the <head> tag:
<script src="//assets.adobedtm.com/launch-XXXXXX-development.min.js"></script>
Initialize Instance
- Create Video Player (Don't init at this stage yet)
- Request VJS extension information
# Initialize BSDK Instance
<syntaxhighlight lang="javascript">
// create player with id specified in video tag
// ….
// Add listener. You can use the following code as a template.
document.addEventListener("nls-vjs-get-data", function (event) {
var customData = {};
var detail = event.detail;
var plId = detail.playerId;
// We must provide playerId field back to the event originator in "nls-vjs-set-data"
var currentSrc = detail.currentSrc;
if (currentSrc === “/path/file.mp4”)
customData.assetid = "SeaHorseID";
var ev = new CustomEvent("nls-vjs-set-data", {"detail": {
playerId: plId, custom_fields: customData }
});
document.dispatchEvent(ev);
});
//
// Initialize BSDK and VJS extensions. You can use the following code as a template.
var ev = new CustomEvent("nls-sdk-init-instance", {"detail":
{
"sdk_instance_name": "inst_" + playerId,
"apid": APID,
"opt_params":
{
"apn": APN,
"sfcode": SFCODE,
"nol_sdkDebug": "DEBUG"
},
callback: function (ret) {
var sdk_instance_name = ret. sdk_instance_name;
var ev = new CustomEvent("nls-vjs-init-instance", {"detail":
{
"playerId": playerId,
"sdk_instance_name": sdk_instance_name,
"callback": function (ret) {
console.log("USER: VJS is ready");
// initialize player (set playlist, ads);
}
}
});
console.log("USER: Sending nls-vjs-init-instance");
document.dispatchEvent(ev);
}
}
});
console.log("USER: Sending nls-sdk-init-instance");
document.dispatchEvent(ev);
// Add the following before </body
<script>_satellite.pageBottom();</script>
},
Event Description
The extensions use the following events to communicate with the user’s page and between each other:
| Event | Sender | Receiver | Description | |
|---|---|---|---|---|
| nls-sdk-get-info | Client-defined | No | "Nielsen Sample App" | |
| nls-sdk-init-instance | Client-defined | No | "1.0.2" | |
| nls-sdk-trackevent | ||||
| sfcode | Nielsen collection facility to which the SDK should connect. |
Inside <body> tag:
// create player with id specified in video tag
// ....
// Add listener. You can use the following code as a template.
document.addEventListener("nls-vjs-get-data", function (event) {
var customData = {};
var detail = event.detail;
var plId = detail.playerId;
// We must provide playerId field back to the event originator in "nls-vjs-set-data"
var currentSrc = detail.currentSrc;
if (currentSrc === “/path/file.mp4”) customData.assetid = "SeaHorseID";
var ev = new CustomEvent("nls-vjs-set-data", {"detail": { playerId: plId, custom_fields: customData } });
document.dispatchEvent(ev);
