▪ Open standard solutions are highly preferred to
proprietary implementations
▪ Internet Protocol (IP) technologies are preferred over
regional or industry segment technologies
▪ Converged networks are preferred when compared to
networks segmented by service type or distribution
technology
▪ Cloud based (centralized) networks are preferred over
client based implementations

A Brief History of VOD
CableLabs® - VOD Metadata Project ▪ SCOPE
- Specifies metadata & interfaces for distribution of video-on-demand material from multiple content providers to cable operators
- Does not address metadata or interfaces for distribution of VOD content from the cable operator to the consumer
• Cable operators today use several different vendor-specific methods for this distribution link
▪ Definition- VOD metadata is the electronically provided descriptive data associated with a content asset package
• Movie title
• Asset management resource information
• Business rules detailing how the content package may be displayed, copied, or sold.
▪ VOD Content Specification 1.0, 1.1 and 2.0- VOD and subscription VOD (SVOD) applications over MPEG-2 systems
• Version 1.0 released February 2002
• Version 1.1 content specification & asset distribution interface released October 2002▪ Deliver metadata separately from content
▪ Updating capability to the package
▪ Use a text-based XML format to describe and to structure the metadata used in these applications
• Versions 2.0 released 2004 ▪ High definition profile
▪ Carriage of vendor-specific trick, barker, and encryption files
▪ More flexible licensing windows
▪ Advertising distribution
▪ Asset structure
▪ Asset inventory messages were issued in early 2007
▪ Allow adaptation of metadata structures to allow repurposing of content for different contracted applications and better controls over content distribution

Estimating TV Everywhere & VOD
Access Capacity Requirements
▪ Unicast Delivery Portable Devices
- Assumptions
- It is desirable to deliver the best
quality video (highest bitrate) to the
subscriber.
- 3.0 mbps to a tablet/pc screen
- 500 Home Passed per Node
- 8 DOCSIS channels per node
- 15% penetration of subscribers
- 25% concurrent use at peak usage
hours
- Bandwidth Utilization Calculation:
(500 HHP x .15 x .25 x 3.0 Mbps) / (8 x
~ 40 Mbps ) x 100%
= ~ 56 / 320
= ~ 18% of the available DOCSIS
capacity
▪ Unicast Delivery to HDTVs
- Assumptions
- It is desirable to deliver the best quality
video (highest bitrate) to the subscriber.
- 8 mbps to an HDTV
- 500 Home Passed per Node
- 8 DOCSIS channels per node
- 60% penetration of subscribers
- 5% concurrent use at peak usage hours
- Bandwidth Utilization Calculation
(500 HHP x .6 x .05 x 8 Mbps) / (8 x ~ 40
Mbps ) x 100%
= ~ 120 / 320
= ~ 37.5% of the available DOCSIS capacity

Content Delivery Network Basics
▪ From Wikipedia, the free encyclopedia
▪ A content delivery network or content distribution network (CDN) is a system of computers containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, so as to avoid bottlenecks near that server.
▪ Content types include web objects, downloadable objects (media files, software, documents), applications, real time media streams, and other components of internet delivery (DNS, routes, and database queries).
www.arrisi.com 2011 CCTV 23
What is a Cache?
▪ Not a web cache, but a cache in general
▪ This is not a rhetorical question
▪ Attendee participation is appropriate here
▪ Don’t all shout out at once
www.arrisi.com
Wiktionary Says
•A store of things that may be required in the future, which can be retrieved
rapidly, protected or hidden in some way.
•Members of the 29-man Discovery team laid down food caches to allow
the polar team to travel light, hopping from food cache to food cache on
their return journey.
•(Computing) A fast temporary storage where recently- or frequently-used
information is stored to avoid having to reload it from a slower storage medium.

What’s a CDN Good For? (and Not)
▪ Good For
- Accelerating web sites
- Providing cost effective
scale for a bursty service
(i.e. trading off CAPEX for
OPEX)
- Reducing latency for
requests
- Standard transports
▪ Not Good For
- Dynamic content
- Proprietary transports

Session management Concept of a session nebulous in this model
Resource management QoS vs QoE. Adaptive streaming.
Service assurance Important aspect of QoE. CDN generates
voluminous amounts of log data. The client can
also produce data. Processing the data can be
a challenge.
Content distribution/content delivery Integrate with Internet style CMS, origin

Conclusions
▪ Implementation of existing VOD technologies may not meet emerging subscriber demands
▪ Meeting the emerging subscriber demands through the simple implementation of new technologies on the existing infrastructure will be difficult and costly
▪ Selection of new components that do not limit flexibility during the transitional phase is crucial
▪ A framework of guiding principles can be used to compare technologies and to evaluate major functional components to assist the operator in developing a strategic path to meet subscriber demands
▪ Starting Point, Stepping Stone or End Goal?

Cable IP Video Hype Gauge
www.arrisi.com
Technology Trigger: A potential technology breakthrough
kicks things off. Early proof-of-concept stories and media
interest trigger significant publicity. Often no usable
products exist and commercial viability is unproven.
Peak of Inflated Expectations: Early publicity produces a
number of success stories—often accompanied by scores
of failures. Some companies take action; many do not.
Trough of Disillusionment: Interest wanes as
experiments and implementations fail to deliver. Producers
of the technology shake out or fail. Investments continue
only if the surviving providers improve their products to the
satisfaction of early adopters.
Slope of Enlightenment: More instances of how the
technology can benefit the enterprise start to crystallize and
become more widely understood. Second- and third-
generation products appear from technology providers.
More enterprises fund pilots; conservative companies
remain cautious.
Plateau of Productivity: Mainstream adoption starts to
take off. Criteria for assessing provider viability are more
clearly defined. The technology’s broad market applicability
and relevance are clearly paying off.
