Our video technology uses HTTP Live Streaming (HLS), which is a common video streaming feature that all major video providers use in one way or another. It works by providing a lower video bitrate (lower possible quality) while the available data stream is established for your web browser. Videos start at a lower bitrate and then improve based on the data stream available, so videos the video will always play and there should be no buffering.
If the available data stream reduces or improves during playback, the bitrate (and perceived quality) will also adjust up to the maximum available HD stream provided by the HLS service. The value provided by HLS is that available videos - even lower-quality videos - is better for viewers than an unavailable video that needs to buffer with other technologies.
