Why Switched Digital Video? Powerful bandwidth management tool
Decouples bandwidth from offered content
Works on existing MPEG-based set-tops
Fully supported on existing S-A set-tops
Enables new programming offerings
Premium, ethnic tiers – enables “the long tail”
Transparent to consumers
More choice - no change in viewing experience
Improves visibility to consumer demand
Provides detailed viewership data
Can be used to enhance targeted advertising
A key component of Next Generation Networks

HDTV is Penetrating the Mainstream Market
1. Increased attractiveness of HDTV sets
Price (ASP) declines
Functionality increases (image quality, size, form factors, connectivity, etc)
Popularity
2. Increased availability of HDTV content
Produced content (lifetime value protection)
Competitive advantage for Networks (ESPN, HBO, ABC, etc)
Competitive advantage for Service Providers (DBS satellite capacity expansion, cable expansion in # of channels)
Mass adoption of HDTV is in full force as early adoption ends.

Competition facing the MSO industry…..
"This is DIRECTV's break-out year for HD," said Chase Carey, president and CEO, DIRECTV, Inc. "The launch of our two new satellites will complete the largest capacity expansion in DIRECTV history, and no other video service will be able to match the sheer volume and quality of our HD programming. With HD adoption now reaching critical mass in the U.S., and 40 million homes projected to have HD-capable TV's this year, DIRECTV will be uniquely positioned as the best choice for HD programming.“
With the launch of DIRECTV 10 and DIRECTV 11 satellites in 2007, DIRECTV will have the ability to deliver more than 1,500 local HD and digital channels and 150 national HD channels, in addition to new advanced programming services for customers.DIRECTV currently offers standard-definition local channels in 142 markets, covering nearly 94 percent of television households in the country, as well as local HD broadcast channels in 49 cities, representing more than 65 percent of U.S. TV households.

Objectives of Analysis Objective
Evaluate viewership dynamics
Develop a sizing model for SDV systems
Number of streams (QAMs) required vs. SG size and channels switched
Demonstrate potential programming gain provided by SDV
ApproachCollect and reduce viewership data collected by Retriever
Create a range of “virtual service group” sizes over which to generate results
Rank channels based on cumulative viewership seconds.
Analyze each virtual Service Group over time to estimate peak SDV stream usage
Fit a curve to the data using curvilinear regression and generate prediction intervals.

TWC Phase II SDV Characteristics
Next-Generation TWC Switched Digital Video Solution Replaces proprietary Phase I solutions Re-architected to provide:
Open, standards-based solutionScalabilityInterchangeable componentsInnovation by vendorsSupport for standard IP networksQAM sharing
System Components communicate via standard, open interfaces Phase II Requires Adherence to Five Key Interface Definitions
SSP-SIS – Session Setup Protocol for Server Interactive SessionsCC-MIS – Channel Change Message Interface SpecificationMC-MIS - Mini Carousel Message Interface SpecificationSDV Server - Edge Device Interface DefinitionDNCS – Edge Device Interface Definition
