• Google Cast Extension: https://chrome.google.com/webstore/detail/google-cast/boadgeojelhgndaghljhdicfkmllpafd

Setup Instructions

• Get a Chromecast device and get it set up for development: https://developers.google.com/cast/docs/developers#Get_started
• Register an application on the Developers Console (http://cast.google.com/publish). Select the Custom Receiver option and specify the URL to where you are hosting the closedcaptioningreceiver.html file (You can use Google Drive to host your files: https://googledrive.com/host/0B716ywBKT84AMXBENXlnYmJISlE/GoogleDriveHosting.html). You will get an App ID when you finish registering your application.
