Charter Spectrum and Time Warner Cable both offer Roku apps that let customers watch programming directly from their Roku video-on-demand boxes. Other cable providers offer access to channels customers normally subscribe to via their Roku boxes using the TV Everywhere service, including AT&T U-verse, Cox Cable, DISH Network, Verizon FoIS and Comcast XFINITY.
Roku offers video-on-demand service through its standalone media player options that connect directly to the Internet. Available in streaming media players and sticks along with 4K UHD players, Roku also comes preinstalled in a variety of smart TVs from several manufacturers. These devices let users add channels via an onscreen interface, and many of these channels require authentication from a cable subscription for viewing.
Some channels available for authenticated subscribers include premium channels such as HBO GO, Showtime Anytime, Starz Play and EPIX. These premium-level channels give subscribers extra content to go along with popular series put out by the channels. Other channels include basic cable offerings, such as A&E, FXNOW, Comedy Central, History Channel and Nat Geo TV.
The children's channels NICK, Disney, Disney JR and Disney XD, and the sport's channels Watch ESPN and the Tennis Channel are available to authenticated subscribers. Network television offerings include Fox Now and NBC. Each cable provider has a different authentication process as of November 2015, so subscribers should check with their providers for instructions before attempting authentication.
