Set Flash Player to auto update in the Adobe Flash Player preference pane.   You have to allow Flash Player on the site as Safari users are sent an acient video player (I found that it reads macOS 10.13 and higher as 10.1 (reported that to Comcast about 3 years ago).   Other browser get a sitghtly broken HTML5 video player (Chroiumum DRM spikes as much as the website tab playing the content)   Should note that Comcast has less than a few months before browsers remove Adobe Flash Player support and Adobe has a EOL date for Flash Player near end of the year.   I can stream 1080 HD and 4k on other sites with no CPU spike but I can't even stream 360 resoution without a 80%+ CPU spike on the site due to broken old code.  The code on the xfinity site runs like it was last updated for IE6 in about 2004. ...

The protocol used for the streams is RTMPE and for some devices RTMPTE.  both encrypt the TCP traffic from one end to the other preventing any man-in-the-middle decrypted stream. That is the current security component while others are not being tested as possible replacements. 1080p (1K) and higher are requiring more and more security to prevent theft of the video by pirates, etc. ...
