  1. Overview

  2. Interest in Video Outstrips Other Features Video functionality second only to voice • 1.5 to 1 preference for video services over camera-phone • 2.3 to 1 preference for video services over push-to-talk Source: QUALCOMM/Spear Research Primary research findings Source: Primary research results conducted by Spear & Associates, sample of 2,800 cell phone and cable users & nationwide focus groups

  3. FLO™Technology

  4. FLO™ Technology: A New Air Interface • Specifically designed for mobile reception of multicast content • Power consumption, memory and form-factor optimized for mobile devices • High Efficiency • Greater than 6 Mbps throughput in 6 MHz • Modulation modes support data rates up to 11 Mbps • Enables large number of channels of streaming content to be offered in one FLO RF channel • Dramatically lower cost per bit than delivery over cellular/PCS networks • Significantly greater coverage per tower than cellular/PCS networks • More efficient than competitive multicast technologies • Higher power transmitters • Fewer sites lower service delivery costs

  5. Ensuring A Quality Viewing Experience • Fast channel switching time • ~ 1.5 seconds • Low power consumption • ~ 4 hours streaming video possible in a standard mobile phone • High Efficiency • More high-resolution media channels, with better coverage • High Quality Services • Video (QVGA, 30 fps, H.264) • ~ 15 channels • Audio streams (AAC+ parametric stereo) • ~ 10 channels • Clip-casting • ~ 40 channels: 20 minutes / day • Arbitrary IP data-casting • Multiplexed with other services

  6. Mixed Networks Optimized for Service Delivery FLO Multicast (one to many – lean infrastructure) 3G Unicast (one to one – robust infrastructure)

  7. Commercial Multimedia Services • Services (channels of programming) - organized in packages for simplified subscription management • Wide area and localized content in a single 6 MHz channel • Wide area and local ad insertion • Blackout & Retune • Familiar user interface

  8. Wide Area and Local Services • Capacity can be flexibly allocated to wide-area and local services • Wide-area services do not experience degradation at the boundary of local service areas Local Area 1 Local Area 2

  9. Transmission Tower Layered Modulation System supports transmission of base and enhancement layers with different levels of robustness • Used in conjunction with layered source coding extends coverage area • Provides a more graceful degradation of reception, as compared to a single grade of service Enhancement Layer 30 frames/ second (maximum) Base Layer: 15 frames/second (minimum) Base Layer: 15 frames/second (minimum) Subscriber A (receives base layer and enhancement layer signals) Subscriber B (receives base layer signal)

  10. FLO Network Content Provider Delivery – National (MPEG2) Content Provider Delivery – Local Content Content Provider Delivery – Local Content INTERNET National + Local Distribution to Towers FLO Transmission to Mobile Devices National Multiplex Distribution INTERNET National Ops Center (NOC) Local Ops Center (LOC) Receive site FLO Transmitters MediaFLO Handset 3G Network Service Key Distribution, Subscriptions Content Provider Delivery - National

  11. Comparison with equal link margins Notes: 1 Due to the nature of S-DMB system, it is difficult to draw direct comparisonsAll technologies are configured for equal link margins Public sources used for other technologies, references provided in back-up

  12. The MediaFLO™ Media Distribution System (MDS)

  13. MediaFLO MDS Content Providers(Shared Content) FLO Network Managed by FLO Operator SAME SUBSCRIBER MediaFLO Client MediaFLO MDS Content Providers (Unique Content) 3G Network Managed by Wireless Operator Integrated Service Overview • FLO network complementary to a 3G operator’s existing network • Integrated Service Model further enhances a robust multimedia offering: • 3G operator-acquired (differentiated) content delivered over 3G network • MediaFLO-acquired (basic or shared) content delivered over the FLO network • All subscribed content distributed in one integrated user interface • 3G networks enable interactive extensions to subscribed content

  14. Network Scheduled Monetizes Unused Capacity • Operator determines the service line-up: channels with content • Each channel has different schedules for delivery and viewing • The MDS • Maintains visibility of user subscriptions • Manages the amount of wireless network capacity required for content delivery • Schedules content delivery to smooth capacity utilization, reducing demands during peak times 100% MediaFLO Traffic Capacity Network Load Time of Day

  15. Access Control • Access rights (service keys) are delivered out of band from content • Access control utilizes asymmetric encryption • Content is encrypted with AES • Encrypted program keys are delivered with the content • Program keys are encrypted with service keys Content is delivered encrypted end-to-end and is never decrypted until it is being played.

  16. MediaFLO USA, Inc. • Deploy a nationwide multi-media network based on MDS and FLO technology • Operates in the 700 MHz band • Maintain a network operations center (NOC) • Procure and aggregate basic content • Deliver a wholesale service to wireless operators in the U.S.

  17. Services that have interest for MESA • FLO avoids several deficiencies with cellular for Public Safety • Does not depend on Cellular to deliver critical messages • Will not be affected by network congestion encountered in Celluar/PCS networks • Emergency notification can be delivered reliably and efficiently • Video based Public Safety instructions can be delivered effectively for large segment of population or select group of authorized personnel • MediaFLO’s ability to have local vs wide area content provides ability to deliver Public Safety related messages only to specific geographical area • Lends itself for development of customized security and public safety applications. • MediaFLO is the best optimized technology to take advantage of the dedicated network that MESA intends to deploy
