API Usage

Initializing a TV Application

Your TV app is created in HTML5. When your TV app loads, the first thing you'll want to do is initialize the Smart View SDK, so that your TV app can receive messages from a mobile application.

Unlike a mobile application, you don't need to "discover" TVs from your TV application. You "are" the TV application, so all you need to do is get a reference to the current or "local" device.

The basic workflow is:

  • Get a reference to the "local" service
  • Connect to a communication "channel"
  • Add Event Listeners
// Get a reference to the local "service"

window.msf.local(function(err, service) {
    if (err) {
        console.log('msf.local error: ' + err);
        return;
    }

    // Create a reference to a communication "channel"
    var channel = service.channel('com.yourcompany.yourapp');

    // Connect to the channel
    channel.connect(function (err) {
         if(err) return console.error(err);
         console.log('You are connected');
     });

    // Add a message listener. This is where you will receive messages from mobile devices
    channel.on('fireMissile', function(msg, from){
         console.log(from.attributes.name + ' says, ' + msg);
     });

    // Add a listener for when another client connects, such as a mobile device
    channel.on('clientConnect', function(client){
        // Send the new client a message
         channel.publish('say', 'Hello '+client.attributes.name, client.id);
     });
});

Enhanced Features

TLS (make secure connection)

2) Sample Code

Tizen Web APP(Receiver app)

    if(err) {
    return console.log(err);
    }
    log('channel.connect');
});
