OpenCable Objectives
• Encourage supplier competition
• Create retail hardware platform
– enable business models
– meet regulatory requirements
• Create common software (middleware) platform
– enable service/application innovation, portability
• Preserve & extend cable’s secure, robust, standardized
digital video technology platform
– integrate new technologies into common cable technology platform
(PVR, VOD, ad insertion, etc.)
– strike a balance between content owners & consumers to enable
new digital services through digital rights management

OpenCable Results
• Technical specs complete, published & available
• New vendors have entered the industry
• Point-of-deployment security modules available and
supported
• OpenCable Application Platform (middleware) largely
complete
BUT
• No retail business has developed
• Can OpenCable do for digital video what DOCSIS did for
the cable modem business?

OpenCable Application Platform
• Middleware approach
– hardware- and OS-agnostic
• Objectives
– enable service/application portability
– preserve supplier diversity
– encourage innovation through common developer platform
• Technical approach
– vendor authors - Liberate, Microsoft, Sun
– incorporate existing standards - HTML, ATVEF, Java
• Draft spec released 1/01; final draft in 7/01
• Profile investigation in progress
– Existing STBs, Advanced STBs

Broadband
• The future is one network for all services…
• “Converged” services on a “converged” network
– for the provider, a converged network
• common provisioning/management/security
– for the consumer, converged applications
• device-independence
• same “look and feel”
• ease of use, plug and play
• High speed IP and MPEG-2

How Does Cable Get There ?
• DOCSIS is a “NIC” (just like a 10Base-T NIC)
• All devices connecting to cable plant use DOCSIS for IP
services
– common provisioning, management, security

Intrinsic DOCSIS Value
• DOCSIS defines:
– standard modulation formats
– standard provisioning environment
• DHCP/TOD/TFTP
–
–
–
–
standard device management (MIBs)
standard link-layer security (BPI+)
standard way to transport IP across cable
secure architecture to put DOCSIS inside hosts

CPE Controlled Cable Modem (CCCM)
• The RIGHT way to embed DOCSIS
• Two years of engineering
• Two fundamental protections
– critical functions protected in CCCM hardware
– software-based filtering moved to CMTS

Cable Services Convergence
• HSD was first to use DOCSIS
– DOCSIS is a NIC, provisioning, management, security
• PacketCable is second service to use DOCSIS
– drives integrated operations
• STB is the right next step
– Work on transition issues: must support legacy

“DOCSIS STB”
• Common provisioning across voice, data, and OOB at
the most fundamental level
• Inherently enables STB to offer high speed IP
applications and services
• All devices connecting to cable plant use the same
DOCSIS NIC

Summary
• DOCSIS for all devices connecting to cable
– converge the network,
– converge the applications
– Enable high-speed IP everywhere
Cable industry unique opportunity
