A lot of people enjoy watching TV through streaming set-top boxes, which basically gives you access to shows for free, and the whole thing is legally speaking, a grey area.
Known as 'Android boxes' or Kodi boxes, a legal case about them kicks off this week.
A trader called Brian Thompson has been accused of selling equipment that "facilitated the circumvention" of copyright protection, and there's going to be a lot of people keeping an eye on it, as if he's found guilty, then everyone else will be for the high jump.
Some of these boxes come 'fully loaded', which means through third-party apps, you can watch pirated copies of TV shows, movies, get access to subscription channels, and all manner of stuff.
Now, the people who are behind Kodi point out that their software doesn't actually contain any content at all, so they're doing nothing wrong.
The Kodi developers even point out that they don't support "piracy add-ons" and have hit out against "fully-loaded" boxes.
On their Google Play page, it says:
"IMPORTANT: The official Kodi version does not contain any content what so ever. This means that you should provide your own content from a local or remote storage location, DVD, Blu-Ray or any other media carrier that you own."
"Additionally Kodi allows you to install third-party plugins that may provide access to content that is freely available on the official content provider website. Any other means of watching illegal content which would otherwise be paid for is not endorsed or approved by Team Kodi."
And in their disclaimer, they add: "Kodi has no affiliation with any third-party plug-in or add-on provider what so ever. We do not endorse the streaming of copyright protected material without permission of the copyright holder."
This is one to keep an eye on.
