Data Networks vs. Video Networks
Video services have higher requirements for video networks
Issue Data Service Effect Video Service Effect
Data Jitter Immune Video frame skips and repeats
Buffering Immune Slows channel change times
Packet Errors Immune except for UDP style services
Video artifactsVideo decode failure
Low Bandwidth Slows throughput Video decode failure
QOS/Priority Management
Latency issue for games; otherwise immune
Video frame skips and repeats in mixed video/data networks
Topology Issues Slows throughput Video frame skips and repeatsVideo decode failure

DHN Tech.
Video services demand guaranteed bandwidth acrossall locations and conditions
• Assume 8Mbps required for two video channels
• Ethernet can guarantee bandwidth because environment is controlled (point to point copper wire – simple topology/environment)
• DHN Technology cannot provide guaranteed bandwidth across all environmental conditions
• Problem area is where DHN technology crosses under required bandwidth.

DHN Customer Care Issues
DHN Complexity– Protocols
– DHCP, TCP/IP, UDP, ARP, RARP, etc.– Data networking vendors are still learning how to
manage phone support for the typical customer– Subtle Problems
– Multiple servers (e.g., DHCP) on the same network can stop operation of specific devices
Combining Data and Video networks on one can create new problems
– Uncontrolled devices disrupt video networks

What a difference five years makes…
“Even though it's possible to use CD-R to record custom music CDs, the price of the CD-R drive plus blank discs and authoring software, along with the general difficulty of digitizing the source audio has kept the practice from becoming widespread. It will be interesting to see if this changes as CD-R becomes cheaper.” - Jim Taylor, "DVD Demystified", McGraw-Hill, © 1998
“Global sales of pirate CDs have more than doubled in the last three years and now generate an illegal international business of $4.6bn, according to the recording industry. Sales of pirate CDs are estimated to have risen by 4%, exceeding 1 billion units for the first time last year, meaning that one in three of all CDs sold worldwide is a fake. Copying is now more accessible with most computers equipped with CD-Rs and a $65 CD burner.” - Houlhan Lokey Media & Entertainment Weekly Update (July 11, 2003)

Paving the Way to Broadband Entertainment
Key Issues1. Technology: Advanced video compression needed2. Infrastructure: Delivery mechanisms & business models3. Security: Only a secure system will get quality content within
the release window(s)
Thomson Assets1. Technology: co-developer of MPEG2, now advancing the
next generation of compression which is 3X as efficient2. Infrastructure: Premiere manufacturer of Satellite, DVD &
Cable distribution systems, #1 share in Broadband DSL. Video set-top boxes for IP networks.
3. Security: SmartRight content protection scheme for end-to-end security in home networks
Thomson technology, assets and relationships will help build a secure broadband entertainment delivery
“ecosystem”
