DOCSIS 3.0 or PONHow to protect investment for now and future, and to maximize utilization of existing CPE, DOCSIS and back office system?How to maintain full redundancy or running in parallel without stranding previous generation hardware?without stranding previous generation hardware?How to stay ahead of the competition without loosing features or adding complexity?Is it ready technically? PON or NG-PON?Do we have enough support on the regulatory side?

Choice
• More content or more “virtual content” with
Reducing Churn by Focusing on 3 Cs
Our VOD Approach
More content or more virtual content with time-shifting
Convenience
• Remember programming the VCR?
• Ever get phone call during your favorite show?
ControlControl
• Make the program schedule fit to my schedule
• “I hate that commercial”
17
DVR users grow “attached” to content on the DVR
The Bottom Line – DVR’s make for sticky, happy customers
Our VOD Approach
40% of DVR households would pay for regular storage upgrades
VOD with DVR a killer combination
43% of DVR customers used VOD first (where available)
DVR customers: churn less, pay , p ymore…
>25% have multiple DVRs (USA)USA Pay TV market expected to be >80% DVR by 2010

1. User request video
2. Video server stream requested video
Our VoD ApproachStreaming VOD vs Push VOD (1)
Streaming VODEach video stream from the video server is an unicast, dedicated to each user for his need to control (pause rev & forward)
requested video
Video server
network
use o s eed to co t o (pause e & o a d)Each dedicated video stream consumes capacity of both network & video serverIn times of high demand (hit-rate), either video server or network will be the bottleneck, hence unable to accept additional request for video
Similar limitations for telecommunications network (e.g. pricing vs erlang traffic modeling)

2. STB’s local storage stream requested videoVideo server
User A
Our VoD ApproachStreaming VOD vs Push VOD (2)
Push VODVideo server broadcast content (usually popular video selection) to settopboxes (STB), stored in its local storage (e.g. harddisk drive) User’s requested video is being delivered from STB’s local storage hence
stream requested videoVideo server
network
User B
User s requested video is being delivered from STB s local storage, hence still able to provide dedicated control to user (for pause, rev & forward)In times of high demand (hit-rate), neither video server or the network will be the bottleneck – works well together with streaming VODTBC and our technology partners (Alticast & Nagra) has developed an improved PushVOD implementation to optimize performance

Summary
Given the advance technologies available today, cable
operators select the best solution to provide next generation
services to its customers
DOCSIS 3.0 deployment can be used to the need for high
broadband speeds
Over time, phased migration to deep-fiber network is an option, as
the demand arises
With video & data convergence, cable operators can take
advantage of both broadcasting network and on-demand
technologies (e.g. DVR & xVOD) to optimize bandwidth &
service quality to stand ahead in the market
