Digital Measurement Video TizenTv
From Engineering Client Portal
Introduction
The following document will highlight the steps needed to run Browser SDK (BSDK) on Samsung Smart TV using TIzen Studio for app development. The tutorial should be used in conjunction with the documentation at Create Your First Samsung Smart TV Web Application to build an app with BSDK integration for content measurement. In this tutorial we will create a native app and highlight the different permissions required to run the BSDK.
Step 1: Install Tizen Studio
Navigate here and install Tizen Studio. During installation make sure to install the TV Extensions package from the Package Manager.
Step 2: Generate Security Profile
Navigate here and generate the security profile in order to run applications.
Step 3: Create Basic Project
Follow the step-by-step guide and create the Basic Project template.
Replace the code in the
index.htmlfile with the code snippet below and update the App ID with a Nielsen provided App ID during SDK initialization.

Step 4: Run Project
Right click on the project > Run As > Tizen Web Simulator Application (Samsung TV)
Extra configurations must be done to run and debug the application on a Target Device, please reference the following guide for more information
Step 5: Debug App
Right click anywhere in the Simulator to open the Web Inspector > navigate to the Console tab > check for BSDK initialization and content measurement.
Debug Logging: Disable logging by deleting
{nol_sdkDebug: 'debug'}
from initialization call
Remote control events
Build out the app further by including remote control events and attaching the player events to corresponding
keyCode
or using Tizen registered keys:
var media = document.querySelector('video');
window.addEventListener("keydown", function (e) {
switch (e.keyCode) {
case 10252: // MediaPlayPause
if(!media.paused) {
media.pause(); // pause video
nSdkInstance.ggPM("pause", playheadPosition); // SDK call
break;
}
media.play(); // play video
nSdkInstance.ggPM("play", contentMetadata); // SDK call
break;
case 10009: // Back
nSdkInstance.ggPM("stop", playheadPosition); // SDK call
break;
...
default:
break;
}
});
