OTT stands for “over-the-top,” the term used for the delivery of video, audio, and other 

multimedia content via the internet without being governed by a traditional cable or

 satellite operator that controls the distribution of the content. An OTT tv box is the

 hardware device, which in this situation, replaces the traditional “set top” cable or

 satellite box with a device that allows the content to be streamed directly to a TV or

 display device. The most popular OTT tv boxes normally operate on the Android

 operating system extending the capabilities of the device even more by adding the

 ability to install and run applications that can be downloaded and installed from any

 location including app stores like the Google Play Store.
