1. Introduction to Freeview Play Freeview Play is the next evolution of the UK’s most popular TV service and is central to Freeview’s and Digital UK’s long term vision for an open hybrid DTT platform. This new service gives audiences easy access to both broadcast and On Demand (OD) content, including a range of popular OD players1 which are available free to users. Freeview Play offers users a common set of the most popular players presented in a way which is consumer-friendly and broadcast-centric. Freeview Play draws on experience of working closely with manufacturers and their proven ability to align with open international standards (D-Book and HbbTV) to facilitate mass market sales. Freeview leads on marketing and is the trusted brand for broadcasters and manufacturers, helping to drive take-up and usage of connected TVs and STBs featuring this unbundled service. Digital UK will lead on product and technical development, working openly and collaboratively with manufacturers and retailers. Freeview Play creates an open internet-connected TV technical standards environment, with built-in HTML-5 and a Metadata Delivery Solution (MDS) enabling a backwards EPG with deep-links to OD content and aggregated browse, search and viewing recommendations across all Freeview Play content. Like Freeview, Freeview HD and Freeview+, Freeview Play is licensed to device manufacturers’ products that meet the light-touch product and technical specifications. Freeview Play compliant devices – primarily iDTVs but also STBs – will be built to a common technical standard and adhere to a consistent line-up of core content and recognisable branding.

2. Freeview Play industry proposition Building on the current Freeview platform, Freeview Play has been working with the consumer electronics industry and other horizontal market partners to develop its proposition and enable devices to launch as soon as possible. The Freeview Play platform has been established by:       

Consulting with manufacturers to develop a technical specification combining Freeview HD and HbbTV. Developing a clear device testing and conformance regime. Delivering a consolidated cross-platform, enhanced metadata stream. Providing a set of rules and guidelines for the user interface and for the presentation of content/players. Underpinning navigation with consumer-driven principles – including one-click access to live TV and the prominent display of core content across linear and non-linear environments. Using simple on-screen branding (on the home screen, in the EPG and on other relevant OD pages). Providing an opportunity for additional Freeview broadcaster OD services to launch alongside the core Public Service Broadcaster (PSB) players. 1

Some of these players, such as the BBC iPlayer, also include live streams.

 

Providing flexibility for manufacturers to provide and position additional non-broadcast OD content. Providing scope for adding new features and functionality.

The following diagram summarises the device manufacturer proposition:

Industry-facing functionality  Metadata supporting regionality.  Dynamic ad-insertion into OD content based on HbbTV 2.0.  Software DRM supporting both pay and free OD content. Technical development and performance  Key performance criteria (e.g. loading times).  Thorough testing of Freeview Play functionality.  Sufficient standardisation to ensure quicker player testing and roll-out.  Adaptive bitrate streaming to maintain video service quality.  Potential for second screen device control. Branding  Logos for Freeview Play on screen, on packaging and at the point of sale.  Content provider branding in the EPG.

4. Freeview Play technical framework The Freeview Play platform has the following key technical features:        

Common HTML5 application environment. Broadcast profile based on D-Book 7 Part A v4 (including MHEG) until March 2016 then D-Book 8 from April 2016. DVB-DASH, Smooth Streaming and HLS based media streaming (with a road-map to providing only DASH streams in future profiles). Aggregated source of metadata providing forwards and backwards EPG with deeplinks to player content; and search API across OD and Freeview content. Ad-insertion into DASH-based streams. Digital Rights Management (DRM) capability. General security requirements. Support for accessibility and companion screen experiences.

The specification uses the D-Book specification as the base profile for broadcast services and signalling. IP-delivered services and applications use HbbTV technologies, including features recently published in the HbbTV 2.0 specifcation. . Freeview Play technical documents reflect the existing profiles of HbbTV available in Europe [TNT], [TDT], and [HBBTV_NL].
