HybridTV Dev Environment is a free Chrome add-on designed to enhance the testing of HbbTV applications within a browser. This tool provides a polyfill that incorporates essential HbbTV functionality, enabling developers to simulate the HbbTV experience without the need for a physical television set. By utilizing HTML5 video elements, it facilitates media playback and dispatches media events onto Open Internet Protocol for Television (OIPF) objects.

The primary objective of the HybridTV Dev Environment is to create an optimal testing environment for HbbTV applications, addressing the common limitations and challenges encountered during development. This solution aims to emulate the behavior of HbbTV apps on actual TV hardware, allowing developers to conduct thorough testing and debugging in a controlled browser environment.
