OCAP Development OCAP Development HistoryHistory• RFP process initiated in September 1999

• Proposals returned October 15, 1999• Review of proposals completed in December 1999• vendor authors selected

– Liberate– OpenTV– Microsoft– PowerTV– CanalPlus– Sun– CableLabs, MSOs and Excite@Home

• Specification development began Summer 2000• Work expedited through the utilization of existing standards and

architectures; started with DVB-MHP 1.0


Presentation EnginePresentation Engine• High degree of compliance with DVB-MHP 1.1• Enable use of tools for developing internet content• Renders declarative content such as graphics, text,

animations and audio• Consists of

– HTML 4.01– XHTML 1.0– CSS 1 and 2– ECMAScript 3– XML– ATVEF


Execution EngineExecution Engine• Approximately 90% compliant with DVB-MHP 1.0.1• Java Virtual Machine• Provides a general application programming environment for

networking, file I/O, graphics, etc.• Security built into the Java architecture• Provides for full TV application environment (with MHP)• Features

– Application management through pJava APIs and XLET controls– Service Information and Selection through JavaTV APIs– Media control through Java Media Framework– Broadcast data through MHP DSMCC APIs– Network management and IP data access – Extensions from OCAP, HAVi, DAVIC, and DASE


Sun License to CableLabsSun License to CableLabs

• Includes pertinent portions of JavaTV API and related IPR.

• JVM Implementation certified and licensed by CableLabs with no obligation to Sun.

• Sun Technology Compatibility Kit incorporated into OpenCable compliance test suite.

• OCAP can specify the Sun Java Virtual Machine and JavaTV as fundamental components of EE.


BridgeBridge

• Enables browser to take full advantage of resources in STB through the Java APIs.

• Minimizes the use of plug-ins (native applications)

• Permits access by ECMAScript application the Java Class Libraries and Java programs

• Permits access by Java programs to the DOM files


SecuritySecurity• Application authentication

– Digital Signatures– Certificates

• Permission levels for applications determines access to system resources and APIs--unsigned applications would have lowest permissions

• Encryption to protect private data


Monitor ApplicationMonitor Application• Optional• Privileged unbound application• Cable system-specific• Control of application life-cycle,

resource management, copy protection, reboot, etc.

• Upgradable


OCAP SummaryOCAP Summary

• Designed for two-way, cable environment.• Support for wide range of applications and

content.• Portability and uniformity of content

display.• Security and robustness.• Resource management.• Open standards.• Support for developers.


OCAP StatusOCAP Status

• Draft specification first release for NDA vendor review - January, 2001.

• Public release OCAP 1.0 - ~June 2001• Test plan, test environment under

development.• First interoperability testing of

applications on different implementations - Sept. 2001.


Harmonization of SpecHarmonization of Spec

• OCAP• ATSC DASE• ATVEF• DVB MHP

• ITU ?


Forum on Forum on Cable Interactive ServicesCable Interactive Services

• Promote cable platform to interactive service/application developers.

• Solicit input into OCAP specification from developer viewpoint.

• Solicit developer input into interoperability test plans and certification of OCAP implementations.

• Recruit service developer contributions in areas of test tools, developer tool kits, training, etc.
