Session Overview Future Technologies Worldwide Digital TV Enabling Premium Content Europe and Japan Hybrid Tuners Call to Action

The Worldwide Move To Digital Analog content sources are still relevant Digital TV is increasingly important Content Larger quantity and variety of digital services Premium content (HBO, Showtime, etc.) High definition audio and video Analog switch-off Motivated by better use of limited bandwidth Transition schedules are set for many countries Full deployment already underway in some places We have made progress with ATSC and DVB-T, but there’s more to do…

Worldwide Digital TV Terrestrial Brazil might adopt ISDB-T

Worldwide Digital TV Satellite

Digital TV Is The Next Big Opportunity But presents some challenges, especially around premium content

Premium TV Content For PCs – Today Content flow to Windows PCs Basic analog capture Available for Terrestrial and Cable broadcast Short term solution due to push for digital Premium analog Analog output of Set Top Boxes (STBs) Challenges Quality (no support for HD video or multi-channel audio) No support for PPV and VOD End-user confusion connecting STB DVR to MCE (with DVR) Prone to errors due to “open loop” control of STB using IR This is not good enough We need a solution that fully enables premium TV in Windows!

End to end content protection and rights management is becoming a requirement: US Digital Cable Japan ARIB ISDB-T/S Conditional Access (CA) protected content US ATSC Broadcast Flag equivalents Developing a common API & crypto solution Simplifies hardware development Simplifies software integration Enables worldwide solutions Challenges for Digital TV on the PC

Protected Broadcast Driver Architecture Features Extends Broadcast Driver Architecture (BDA) Protects content from the TV tuner to the operating system Standardizes crypto APIs Worldwide solution Broadcast standard and CA independent Uses industry-approved Windows Media DRM Device support Integrated (PCI/e) devices through BDA extensions IP-based devices through Digital Receiver Interface (DRI) with Windows Vista Class driver

PBDA-KS Primary design consideration: regional regulatory constraints (e.g., ISDB, Broadcast Flag) Local / integrated devices Extends BDA devices Form factor: Highly integrated Dedicated device (serves single PC) Mini-driver must support new API PBDA-IP Primary design consideration: network operator constraints (e.g., CableLabs, Premium Satellite) Network based devices Extends network devices (UPnP, WSDL) Form factor: External, detachable Shareable device (serves multiple PCs) Class Driver: No driver required Enables secure delivery of premium content to Windows Common chip-level hardware requirements (crypto) Supports host or device screening (including bulk mode) Worldwide solution (broadcast standard and CA independent) PBDA Implementations

PBDA – Content Protection Screening on receiver device or host PC Macrovision, CGMS-A, Redistribution Control (RC) Broadcast Flag, CA Copy Control Information (CCI) Broadcast Flag, CA Copy Control Information (CCI) Content protected by Windows Media DRM Proximity detection Device registration License generation Content scrambling Revocation and renewability

WMDRM Advantages Robustness agreement and license required to obtain a certificate for access to WMDRM protected content Strong encryption across User-Accessible-Bus and file storage AES-128HDCP RSA-1024 for key exchange Strong compliance and robustness rules Devices and applications can be revoked or renewed Working with reputable vendors and OEMs to insure high quality services with secure content Approved by DTCP (5C), CPRM (4C), CMLA, AACS, Macrovision, CableLabs, and CSS for output protection

PBDA Hardware Requirements Common technologies used for all profiles RSA 1024 bits SHA1 160 bits AES 128 bits OMAC1 Random number generator XML certificate parsing Applies to both PBDA-KS and PBDA-IP

Supporting Worldwide Digital TV Standards

Japan

Japan Digital TV challenges Getting Consensus Multiple standards bodies (ARIB, D-PA, B-PA) Contract from conditional access provider (B-CAS) Multiple broadcast standards ISDB (ARIB TR-B14/15) Specifications in Japanese New Interactive TV standards (BML) Extensive in-country testing required Today’s ISDB tuners are expensive and specialized

Japan Microsoft investments Building relationships with the industry Regulatory bodies (ARIB, D-PA, B-PA) Conditional access provider (B-CAS) Broadcasters Partnering with key partners for Interactive TV solutions (BML) Engaging potential partners IHVs, ISVs, and OEMs Dedicated product development team in Chofu Technology Center (CTC) Focus on ISDB technology initiatives

Japan Key TV features ‘07 PBDA tuners for ISDB Premium content with B-CAS support Live and recorded HD/SD TV Interactive TV (BML) In-band guide (SI/EPG) Protected content pipeline Video, audio, and data ARIB TR-B14/B15 compliance

Europe

Europe Digital TV challenges Market fragmentation Staggered and varied adoption of DVB standards (DVB-T, DVB-S, and DVB-C) (DVB-T, DVB-S, and DVB-C) Multiple Interactive TV standards (MHEG, MHP, SMS) Mixture of free and pay TV for both DVB-T and DVB-S Multiple Conditional Access (CA) Multiple business models CA requirements vary per broadcaster Long lead-times for business engagement Extensive in-country testing required Subtle technical differences between different broadcasters and cable operators

Europe Microsoft investments Development agreement with FSC DVB technologies (Satellite, Terrestrial, and Cable) Working with leading partners in the iTV space for key feature support Technology collaboration with NagraVision Enables Premium Pay TV in Europe Dedicated product development team in European Development Center (EDC) Focus on DVB technology initiatives

Europe Key TV features ‘07 DVB-T and DVB-S/S2 free-to-air and DVB-CI Hybrid tuners Merged program guide (PAL/DVB-T/DVB-S) DVB-T subtitling and DVB Teletext In-band EPG for DVB services Interactive TV with MHEG5 Improved service scanning FM radio station naming and analog TV channel renaming

Hybrid Tuners Demand for crossover solution tuners by OEMs Regulatory mandates to support both formats to future proof today’s solution for TV receiver devices Offers more flexibility to users without changing out hardware Most vendors are building these solutions today (PAL + DVB-T, NTSC + ATSC + QAM) through a mix of supported driver models Hybrid tuner model simplifies driver model solution and allows a better way to configure usage of all tuner capabilities

Hybrid Tuner Requirements Hybrid digital/analog tuners must support the following analog video processing Hardware MPEG-2 audio and video compression to Packetized Elementary Stream (PES) VBI data slicing and conversion to PES stream NTSC: Line 20, 21 PAL: Teletext, Line 6, 23 Delivery of Audio/Video/Data as MPEG-2 TS multiplex Single service transport stream with PAT/PMT and Audio, Video and Data streams Tuner driver interface refinements to define supported standards and add encoder settings for analog capture
