Q. I know Roku has streaming channels like Netflix. But are there channels that are free? And do you have to pay a monthly fee to subscribe? — Judy, Seattle.

For those not familiar with Roku, it’s a set-top box or streaming stick that can send video and audio channels over the Internet to your TV. (Roku’s software is also available in some TVs, including TCL models such as this one.) You connect the Roku set-top to your TV using an HDMI cable and then capture the signals either using your wireless home network or a direct wired connection. (The Roku streaming stick is connected directly into the HDMI port.)

Judy, you’ll be happy to know that Roku does not require a monthly fee like TiVo.

The difference in the two is that TiVo is a DVR which allows you to record programming from traditional TV channels for future viewing. (Some TiVos offer other features as well, including streaming from services such as Netflix.) Roku is a set-top box that allows you to watch and listen to channels that are available on the Internet; the company does not charge you a fee for this.

So, what’s the catch? Do you have to pay anything?

Well…yes. For starters, Roku products start at around $30.

Second, Roku offers a mix of free and subscription-only or PPV channels. The latter category includes Netflix, Amazon Instant Video, Sling TV, DIRECTV Now, Showtime, Hulu, Vudu, MLB.TV, HBO Now and the NFL Sunday Ticket, among many, many others. They either require a paid subscription or, in the case of Vudu, a Pay-Per-View fee for each movie you watch.

But Roku has quite a few free channels, too, such as the CW, YouTube, Pandora, CBS News, PBS, PBS Kids, Crackle, Pluto, WeatherNation, Sky News, TechCrunch, CNET, Popular Science, NASA, Vevo, IHeartRadio, TuneIn, Smithsonian Channel and Twitch.
Roku also has its own free channel, called The Roku Channel, which offers movies for no extra charge.

You can also watch a number of on-demand versions of cable channels for no extra charge if you subscribe to them through your cable, satellite or telco TV service. This category includes HBO Go.
