Implementation of a sub-system for DIAL verification within HbbTV test environment

The HbbTV 2.0 specification, published in 2015 by the Hybrid Broadcast Broadband TV (HbbTV) Association aims to integrate companion screen devices (mobile devices, tablets, etc) into HbbTV environment. This enables broadcasters to utilize second screen devices in order to show additional content-related information, stream broadcast content or launch and install native applications. In this paper we present an environment and tools used for verifying DIAL functionalities on HbbTV 2.0 compatible devices.
