live-worshipYou might not be aware but there are numerous parts and pieces that make live streaming church technology work. Amid these parts of your church’s streaming system, the 3 major ones are the internet connection (from your internet service provider, ISP), the media encoder (hardware or software) and the global Content Delivery Network (CDN, also referred to as a hosting web server). There is no doubt that all the key elements have their role to play in successfully streaming video online.

So, let’s first discuss the route, in reverse, of the audio/video signal that you intend to webcast.  Starting from the viewers end; first a viewer goes to a webpage and clicks on a file they want to view. After that click, the request is sent to the CDN (hosting web server) that is storing the video file (or live stream Url) and the file to begins to play.

Secondly, it is important for the CDN that is hosting (aka storing) the video or audio file to be globally accessible and on a robust and responsive network. The requested files & other content are processed and then sent to the online user via protocols that recognize how best to transfer the dta from the hosting server (CDN) to the user’ device (PC or mobile).  The most frequently used protocol is an HTTP-based media streaming communications protocol implemented by Apple Inc.  The protocol is called HLS, which stands for http live streaming.  HLS is the most widely accepted standard for global live streaming.  In the opinion of this writer, it is also the most reliable and covers 90% of all browsers, screens and mobile devices.

The third step is for the webcaster to properly format the video and audio signal.  For effective HLS encoding, you will set your video format (via your encoder hardware or software) to H.264 and set your audio to AAC/Stereo.

Finally, please consider consulting a professional live streaming provider, such as Worship Channels, to ensure all your equipment, settings and systems set up for optimal performance.
