CBS will be the host of a number of NCAA Tournament contests and that may be a problem if you live in a place that does not have good antenna reception. But there is great news. If you happen to live too far away to watch the games over the air you can instead watch the games broadcast on CBS via the CBS website. They are streaming live directly through the CBS Sports Website.
There is not a free TV-based app to watch the games. CBS has limited streaming to TV-connected devices like Roku or Fire TV to the CBS All-Access app. Users are able to use the March Madness live app on mobile devices in order to watch the action on the go. Users may want to experiment with chrome casting, mirroring, Airplay and other options as well.
