The OST, or Open Standards Terminal is a software platform initially proposed by Nokia for devices such as set-top boxes, for the purpose of bringing a number of application to the television set. Examples include digital TV, video recording, web browsing and games.

The platform is based on open software, such as Xfree86 (the de facto graphical windowing system for many modern unix-clones, such as Linux and FreeBSD) and Mozilla for web browsing and web-based applications.

Nokia has created a web site to recruit and encourage new developers to the platform; http://www.ostdev.net/
