3 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 2 Why WPANs? The appeal of WPANs –Connectivity –Low cost –Low power consumption –Ease of use The added appeal of medium and high speed WPANs –High bit rate to support multimedia 12

4 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 3 What is the consumer multimedia payload? Involves Video –Games –Internet access –Broadcast/cable/satellite TV –Movie content What is the digital video issue? –Protecting copyrights

5 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 4 Why Protect Copyrights? The majority of popular digital content is movies and audio Perfect digital copying is the issue –Movie content –Audio content Protection is needed for movie content and audio content

6 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 5 Will Security features suffice? No! But it is a key part of the ‘security wall’ Lines of Defense security –is the against casual ‘ease dropping’ Content encryption adds more protection Digital Rights Management Out of Scope Out of Scope

7 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 6 What is there to worry about? Ease Dropping Media Storage Neighbor enjoys same content!!

8 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 7 Why worry? Digital video is a big market Market Volume Reduced unit costs Let’s look at some numbers

9 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 8 Is Digital Video Important to ? Here are some 2001 sales numbers*: Analog TV, including projectors26.7 mil DTV sets and monitors~1.1 mil VCR decks14.9 mil Total Camcorders 5.3 mil DVD players12.7 mil * Numbers drawn from various issues of TWICE Magazine. Apply to only US.

10 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 9 Is Digital Video Important to ? Here are some 2001 sales numbers*: Analog TV, including projectors26.7 mil DTV sets and monitors~1.1 mil VCR decks14.9 mil Total Camcorders 5.3 mil DVD players12.7 mil DVR (key to future home multimedia center) ? * Numbers drawn from various issues of TWICE Magazine. Apply to only US. Which of these devices need security? DTV sets and monitors DVD players DVR Total Camcorders

11 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 10 The Cost Factor has low cost as a goal Consumer market is highly competitive Mobility is a value added, not a baseline value Multiple ciphers increases cost for assured interoperability Lowest cost uses single cipher (default) Options for additional ciphers allows value added Lowest cost uses single cipher (default) Options for additional ciphers allows value added

12 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 11 Summary Key points Movie and audio content –Copyright protection needed (out of scope) –Home application is a big market –Link security is a required part of copyright protection Assured security required (interoperability) –Default cipher necessary –Option cipher good for value added Low cost is important in consumer market

13 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 12 Interrelated for Success: Hi Bandwidth Security Low Cost Video Content with Copyrights Low Power Consumption Out of Scope

14 Submission doc.: IEEE /044r0 21 January 2002 Bob Huang, Sony ElectronicsSlide 13 The End Thank You
