HbbTV is a new industry standard providing an open and business neutral technology platform that seamlessly combines TV services delivered via broadcast with services delivered via broadband and also enables access to Internet only services for consumers using connected TVs and set-top boxes. The founding members of the HbbTV consortium together with a large group of supporters jointly developed the HbbTV specification to create a global standard for hybrid entertainment services, for the delivery of broadcast TV and broadband TV to the home, through a single user interface, creating an open platform as an alternative to proprietary technologies. Products and services using the HbbTV standard can operate over different broadcasting technologies, such as satellite, cable, or terrestrial networks.

The HbbTV specification is based on existing standards and web technologies including OIPF (Open IPTV Forum), CEA, DVB and W3C. The standard provides the features and functionality required to deliver feature rich broadcast and internet services. Utilizing standard Internet technology it enables rapid application development. It defines minimum requirements simplifying the implementation in devices and leaving room for differentiation, this limits the investment required by CE manufacturers to build compliant devices.
HbbTV can show digital television content from a number of different sources including traditional broadcast TV, Internet, and connected devices in the home. To watch hybrid digital TV, consumers will need a hybrid IPTV set-top box with a range of input connectors, including Ethernet as well as at least one tuner for receiving broadcast TV signals. The tuner in a hybrid set-top box can be digital terrestrial television (DVB-T, DVB-T2 ), digital cable (DVB-C, DVB-C2) and digital satellite (DVB-S, DVB-S2).
