When Everything is IP

A Few Technologies of Interest, and Concern

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

From a July, 2003 IEEE paper on H.264

The Coding Advantage of MPEG-4/H.264/AVC vs. MPEG-2For Entertainment Content in HD

HDTV – Tomorrow’s Compression Advantage

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)
