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.html

file 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)


Tizen 1 Step4.png


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;
    }
});
