The video streams provided allow for a variety of bitrates (i.e. levels of quality) to ensure that your device receives the best quality signal. The video player also dynamically adjusts your stream upwards or downwards based on a number of factors, including network capacity, CPU and memory utilization, graphics card capabilities, etc., so that you're getting the 'optimal' video quality based on your computer's specific capabilities.
