2 Introducing Roundbox Mobile Broadcast and Multicast Software Client / server; infrastructure / applications Core products Electronic Service Guide Datacast infrastructure Multi-network / Multi-application Multiple delivery networks Broadcast, multicast, unicast DVB-H, BCMCS, FLO, others More than TV Company Overview Headquartered in Florham Park, NJ Remote offices - San Francisco, CA and Bordeaux, FR Series A $6M Dec 2004 RRE Ventures and Core Capital Series B $15M April 2006 Polaris Ventures Board of Directors Tom Wheeler, former President / CTIA Bob Geiman, General Partner, Polaris Rich McGinn, former CEO / Lucent Technologies 2

3 Why Mobile Multicast / Broadcast? May Help to Answer to the Question What Happens When 3G Multimedia Applications Are Really Successful? Guaranteed QoS Not sensitive to time and space congestion Broadcast traffic latency and QoS is unaffected by point-to-point network status and traffic volumes Most relevant for simulcast media streaming ( Mobile TV ) and notification apps Zero Incremental Cost Efficiency benefit for high uptake services with common content Use for catalog or teaser content to generate point-to-point transactions that are known to have revenue attached to them Avoid operator cost associated with unbilled point-to-point data traffic Relevant for content distribution applications even without QoS issues Localization Natural localization at granularity of broadcast technology Network efficiency may allow finer localization based on client filtering 3

4 BCMCS Overview Specification for Multicast Within EV-DO Coexists with point-to-point packet data Reuse and extension of existing IP packet encapsulation protocols Single copy of multicast packet reaches all listeners Packets Sent Over Forward Link Static: sent to a predetermined set of sectors Dynamic: sent to sectors in which terminals have registered for a given flow New Functional Elements Broadcast Serving Node: multicast packet distribution within core Controller: multicast session information and scheduling, key distribution Content Server: multicast reflector, encryptor Protocols Added for Path setup and RAN session information Session information to terminal Security and media encryption 4

5 BCMCS Network Architecture 5

6 BCMCS Capabilities Basic BCMCS (or BCMCS Gold ) Air interface defined in C.S0054 Physical layer reuses EV-DO Rev. 0 physical layer Enhancements such as soft combine Data rates up to ~400kbps Enhanced BCMCS (or BCMCS Platinum ) Air interface defined in C.S0054-A Capability available in Rev. A chipsets Physical layer uses OFDM, integrated with EV-DO TDM Improved energy and behavior at cell edges allows higher rates Data rates up to ~1.5Mbps 6

7 Mobile Multicast / Broadcast Bearer Technologies Mobile Operator CDMA BCMCS GSM MBMS 3G Multicast kbps MediaFLO Mobile Operator USA FLO Content Provider DVB-H Handset Satellite Terrestrial Wholesaler Satellite Wholesaler DAB /DMB ISDB-T Dedicated Broadcast 5-20 Mbps Broadcast Network Operator Technology 7

8 BCMCS As Mobile Broadcast Bearer Generic Broadcast Advantages Zero incremental cost Consistent QoS, simultaneous delivery Advantages Versus Dedicated Broadcast Easy to roll out incrementally Existing radio network and receiver Dynamic resource usage Network and/or terminal-driven path setup Fine-grained localization - sector level Disadvantages Limited bandwidth Total IPDC bandwidth for single carrier smaller than typical dedicated network Initial rollouts may cannibalize EV-DO data usage 8

9 Mobile Broadcast Application Categories Mobile Streaming Media High profile initial mobile broadcast application is Mobile TV Improved video quality versus unicast simulcast media services For high uptake, clear cost issues for unicast solution Natural fit for existing broadcast infrastructure vendors Dynamic Multicast Media Multicast PTT Large-scale videoconferencing Emergency notification IP Datacast Content distribution Real-time event streams Large-scale real-time notifications 9

10 Datacast It s s The Economics Videocast Datacast Single Live Game 30 FPS CD Audio Every Live Game Real-time Events Audio Alerts 1 x 250kbps 1 of 25 x 10kbps Part of Basic Cable Package? Premium Service ($5/mo?) 10

11 Datacast Application Attributes Characteristic Push Data Concurrent / Real-Time Background Transfer Localized Broadcast Client Filtered Synergy Description One way flow of structured data which is visualized on the mobile device (event stream, notifications, data object distribution) Large # of clients receiving same data simultaneously; synch with real world events Trickle data in the background ( push portal, may contain teaser or full content), or dynamically push data objects Network manages coarse- or fine-grained localization of content, may be further filtered by the client based on location Bulk data pushed, elements of interest are filtered up by client software Mix datacast modes and/or tie datacast to other broadcast content (trivia, voting, advertising) 11

12 Example Datacast Applications Active Wallpaper Real-time Sports Datacasting Broadcast Storefront ( Push Portal ) Local Maps And Traffic Real-time TV Play Along Stock Ticker Security Alerts Real-time Voting 12

13 BCMCS Use Case: Optimization of Unicast Services KDDI announcement of Gold BCMCS deployment Preceded Rev. A deployment scheduled for EOY2006 Multicast Employed for Optimized Versions of Services That Already Existed in That Market (and Others) EZ News Flash Periodic update of news, weather, entertainment, sports information Displayed on idle screen ( Active Wallpaper ) Links to portal sites for additional information EZ Channel Overnight download of media content subscribed to by user ( Push Portal ) Currently point-to-point download 13

14 BCMCS Use Case: Localized Datacast Asian Operator With Existing Partnership for Mobile TV Dedicated mobile broadcast network operated by partner Limited revenue share to mobile operator Trialing BCMCS for Localized Services Limited media streams Localized information and advertising Event stream datacast applications that are global to the network Stocks, news Datacast services with localization and interactivity Advertising, merchandising Complementary services to Mobile TV Unified service guide 14

15 Datacast Application Platform Mobile Broadcast Bearer Technologies All Provide IP Multicast Encapsulation Capabilities Most Technologies Provide Standardized Services for Media streaming Background filecasting Roundbox product line includes a datacast client / server application platform that enables Ease of datacast application creation App writer uses familiar environments Unaware of broadcast transport details Operator control and monitoring Gating and optimization of bandwidth usage by multiple apps BCMCS integration Datacast app support infrastructure integrated with controller and content server functions 15
