Why specify interactive TV? For maximum benefit from digital TV (for both viewers and broadcasters) a middleware should be specified and deployed on all receivers in a network to support interactive services and applications including: – Platform EPG (Electronic Programme Guide) – Digital teletext and information services – Enhanced TV formats (programme related) – Games and voting/participation TV formats And with Interaction Channel (return path) – Audience measurement – Operator information / account management – t-commerce for shopping channels – e-government 25 th February 2008 BES Expo MHEG-5 S&T
Middleware considerations • Interactive TV works best when all (or the vast majority) of the receivers in a market have middleware installed • Content and services that reach just a small percentage of a broadcaster’s audience do not support a viable business / commercial model • Technical standard considerations are important but not as important as enabling an audience for interactive services • No Audience = No Business! 25 th February 2008 BES Expo MHEG-5 S&T
Using Public Standards • Use of Public Standards enables: – widespread adoption and – multiple vendors at each part of the industry chain – price and performance competition • Requires conformance scheme to ensure interoperability and ease of use 25 th February 2008 BES Expo MHEG-5 S&T

MHEG-5 • Developed in ISO-MHEG group and DAVIC in 1995 • • Standardised in ISO 13522 -5 Adopted by UK DTG in 1997 UK Profile includes text, graphics and DSM-CC carousel systems Profile evolved to UK Profile 1. 06 (current) ETSI standard ES 202184 NZ profile extends to include extra Maori characters and EPG key New Hong Kong profile released with support of Traditional Chinese Extensions under development for deployment in 2008 – Intended as UI for DAVIC interactive services and VOD – Simple object oriented interpreted language – – IP Interaction Channel (return path) PVR support Improved graphics HD compatibility 25 th February 2008 BES Expo MHEG-5 S&T
MHEG-5 Rollout • Successfully deployed in UK • Launched in New Zealand in May 2007 • • • Trials and evaluations in Ireland, Hong Kong, Malaysia, Singapore, Turkey, India and Russia with interest from other countries in Europe and Asia No known essential IPR MHEG middleware software approx US$1 per receiver Lowest retail price in UK <$40 Wide integration into i. DTVs in Europe • Note the above applies mostly to MPEG-2 platforms in 2008 – >18 m receivers sold – a single S&T customer shipped 700 k units in Q 3 2007 – 99% UK Freeview platform penetration, >25% usage – DVB-S receiver sales over forecast so far (already >40, 000 units) – DTT launches 2008 with MPEG-4 HD and MHEG-5 – 50% of sales i. DTV…MHEG available to most leading brands 25 th February 2008 BES Expo MHEG-5 S&T
What is MHEG-5? • Simple object orientated programming language – to control presentation of content made up from audio, video, text and still graphics objects – to provide user interaction with the application – supporting real time video and audio presentation – focussed on TV requirements – low overhead and high speed • A complete environment including – Authoring tools and data systems – Broadcast transmission using DSMCC Object Carousel standard and optional IP-based connectivity – Middleware – the MHEG middleware or ‘stack’ that is resident in the STB. This provides an API on which interactive applications can run 25 th February 2008 BES Expo MHEG-5 S&T
MHEG vs Java • MHEG-5 is designed specifically for TV presentation – – Remote control operation Displays built on TV layout Works in its own safe memory space Robust interpreted language • Java is a complex general purpose tool with adaptations for TV • As illustration of comparable complexity – MHP (based on Java) has >10000 unit tests • There are no other standardised Java systems for TV – MHEG has <350 test • But there are very few, if any, broadcast applications for TV that can be done in MHP and not MHEG-5 • MHEG-5 loads and runs faster 25 th February 2008 BES Expo MHEG-5 S&T
MHEG applications are smaller Source: MHP/MHEG Coexistence project. BBC Research. • Smaller applications means faster start and lower cost transmission 25 th February 2008 BES Expo MHEG-5 S&T

MPEG-4 and MHEG-5 • Inclusion of HD/SD MPEG-4 in the system makes a difference to a number of issues – – Cost of silicon Number of receiver suppliers in short term Complexity of receiver outputs MHEG-5 display strategy for HD services • Receiver costs are higher in short term – but bandwidth utilisation is better • Next generation i. DTV will include MPEG-4 • Receiver solutions have easy IP connection • MHEG-5 HD support in development for 2008 25 th February 2008 BES Expo MHEG-5 S&T
Projects using MPEG-4/MHEG-5 • Freeview NZ DTT – Launches 2008 • Republic of Ireland – Launch 2008 • Many i. DTV designs for 2008/9 will incorporate both technologies • Freesat in UK – Launch 2008 • Hong Kong DTT (TVB) – Launch 2008 – Receiver manufacturers already working on implementation • Others in planning phase 25 th February 2008 BES Expo MHEG-5 S&T
