The document discusses the Multimedia Home Platform (MHP) standard. MHP is an open standard software platform that allows digital television receivers to run interactive applications and services. It provides a common interface for developers and allows for a variety of devices and services to work together. The document outlines the benefits of MHP including cost savings, a thriving market, and increased access to pay-TV and internet services for consumers.

Why a standard for
interactive DTV ?
 Without a standard you will have:
 Consumers would need multiple boxes to receive multiple services.
 No cost-effective Free-To-Air digital TV products.
 Islands of Pay-TV subscribers, using different incompatible technologies.
 Uncertain consumers refusing to buy products.
 Over 50% of population long term without Pay-TV. (“Digital Divide”)
 With a standard you will have:
 One STB or iDTV box to receive all services (just like the GSM market)
 Consumers buying STBs & iDTVs in retail stores (No subsidy models necessary)
 A thriving market in Equipment, Content, Services, Products (Economy of Scale)

What is MHP?
• MHP is Software
• Like “Windows” but for Digital Television
• Based on a standard so we will not have to pay one
company for ever
• Softworks makes MHP software, but so do others
• Think of it as like the “teletext” feature was for analogue
• Teletext used to be thought of as too expensive and
complex

The new paradigm for
interactive applications
 Dis-entanglement of the chain:
 Interactive content produced by content providers
 Driven by open standards (MHP)
 Focus of service providers:
 Services that are independent of TV channel (Service Guide, Portal, VoD,
PPV, Service channel, Internet access etc.)
 Revenue sharing based on added value to broadcasters or advertisers
(consumer data / profiles) creating win-win
 Increase competition
 Reduce prices and costs
 Focus on value adding instead of blocking
 Increase freedom of choice for consumers
 DRIVE MOMENTUM for roll out of Interactive TV services

What’s in it for
broadcasters?
• Huge Cost savings
• Don’t have to buy boxes!
• Pay-TV capable
• Cheaper broadcast equipment
• Cheaper Applications – can buy them
• Huge savings on return channel infrastructure
• Use viewers ISP to get to internet
• Use web servers as return infrastructure
• Interactive offering for Free-to-air

Conclusions
 Proprietary standards have been good to get a fast time to market
 However, economical production of interactive digital TV content
requires open standards and mass deployments of devices
 Consumer adoption of DTV will be driven by the amount of compelling
interactive content and services offered
 Horizontal and vertical models will co-exist
 Each player in the value chain can have a good business
 Each stage in the value chain has many subsidiary businesses supplying
it.
