Rate Shape – “Fold” the video peaks into the valleys to produce a CBR stream
Rate Convert – Pull “bits” out of the video to reduce the CBR stream size
Transcode – Video bit stream format conversion from source (MPEG-2) to target (MPEG-4)
A Few Technologies of Interest, and Concern
 IP versus RF for Broadcast TV
 High-Definition Television
 MPEG-4/VC-1
 Content Protection
 Ad/Program Insertion
 When Everything is IP
IP versus RF for Broadcast TV
• Advantages/Disadvantages of RF
• No need for a STB for RF modulated Analog channels
• Limited (proprietary) interactivity for advanced services
• Potential for service theft via spoofing filters and pirate STBs
• Advantages/Disadvantages of IP
• Common format regardless of service
• Large opportunity for interactivity
• Large opportunity for cross-media services
• Limited potential for theft of service
• In sync with FCC push to all-digital TV
• Set-top box per TV or multi-TV gateway required
• Potential for theft of digital content
HDTV – Just What is It, Technically Speaking?

HDTV – Tomorrow’s Compression Advantage
The Coding Advantage of MPEG-4/H.264/AVC vs. MPEG-2
For Entertainment Content in HD
From a July, 2003 IEEE paper on H.264
Content Protection
• Theft of Service
• Major issue in RF deployments due to downstream only nature
•Hijacked analog taps and STB Filters
•Pirate STBs (multi-settops in the home)
• Minor issue in IP deployments due to two way acknowledgment
•Middleware closed loop STB provisioning
•Difficult to emulate a STB with a PC (MAC Addr + Client ID)
•Theft of Content in an IP World
•All content is high quality digital until it exits the STB
•Need to protect both Stored and Premium Broadcast video
•Content encryption + middleware = conditional access (CA)
