OCAP RI Branching Strategy

• Three principal branches» Trunk/Development Branch

– Code implemented by internal RI Dev Team– Code from open source contributors that are vetted by RI Tech Leads– Other working branches get merged back to Mainline periodically

» Branded Branch (eg, “1.1.4”)– Fixes and enhancements that are tied to the spec and which have been

verified by the CTP– Branded branch is maintained separately from mainline– Changes from branded branch eventually migrate back to mainline

development– One branded branch per spec release

» Experimental Branch– Open source contributors have write access to this directory– No other restrictions– Merging to Trunk on a case-by-case basis

extensive modifications– DirectFB, FreeType, Zlib

• tools» Unmodified open source (non-GPL) libs used by the stack

– JUnit, NanoXML, cybergarage uPnP, Log4J, etc..– cybergarage is heavily modified and probably should move

to “thirdparty”


Java Packages

• org.dvb, org.havi, org.davic, org.ocap» Specification defined packages

• javax.tv» JavaTV

• org.cablelabs.debug» Logging and profiling

• org.cablelabs.impl» Java implementation packages


Build System


Build Tools

• Make» Compiles JNI, MPE, MPEOS, and thirdparty

native libraries• Ant

» Coordinates the entire build system» Wiki contains a list of top-level build targets

• JDK (1.4 or higher)» Used to compile stack and test application

sources


Build System – Environment Variables

• Easy to work in several different RI code bases at the same time.

• OCAPROOT» The absolute path to the ri/RI_Stack directory.» Required for compilation/execution

• OCAPHOST» Defines the host build environment» Build system reads host environment configuration files

from ($OCAPROOT/hostconfig/$OCAPHOST)» Required for compilation only


Build System – Environment Variables

• OCAPTC» The Target Configuration for the build. Basically the port

you are working on.» Defines a subdirectory hierarchy where:

– build configuration files are found ($OCAPROOT/target/$OCAPTC)

– binary intermediate products are built $(OCAPROOT/gen/$OCAPTC)

– final binary products are installed and runtime configuration files are kept ($OCAPROOT/bin/$OCAPTC)

» Suggested format is:– <org>/<platform>/<os>/[debug|release]– CableLabs/simulator/Linux/debug

» Required for compilation/execution


Stack and Platform Configuration


Stack Configuration – Native

• mpeenv.ini• Configuration parameters for SI,

ObjectCarousel, JVM, and more…• For the RI Platform, mpeenv.ini is located in

$OCAPROOT/bin/$OCAPTC/env• For a specific port, it can be located anywhere

»Stack boot module must pass the location of this file to one of the MPE managers


Stack Configuration – Java

• Java properties files, per extension• Located in $OCAPROOT/java/src/<module>/<module>.properties

» Do not modify these files• Modules are organized into a precedence hierarchy defined in

$OCAPROOT/java/src/base/org/cablelabs/impl/manager/props.properties» Do not modify this file» Stack can choose to use a single property value based on highest module

preference or aggregate the property values for all included modules» Helps with separable extension builds

• “final.properties” is the final user-level override file for Java configuration properties. » Must be found in the root of a classpath entry.» Place your user-specific overrides in this file to modify stack behavior.» For PC Platform, located in $OCAPROOT/bin/$OCAPTC/env


Stack Configuration – Java <cont>

• Most common final.properties overrides– OCAP.mgrmgr.manager.Auth=org.cablelabs.impl.manager.auth.AuthManagerImpl

• Enable application authentication. Default is disabled

– OCAP.mgrmgr.manager.OcapSecurity=org.cablelabs.impl.manager.security.NoAccessControl

• Disable Java permission checks. Default is enabled

– OCAP.xait.ignore=true

• Disable XAIT acquisition entirely. Only hostapps are loaded.

– OCAP.cablecard.manufacturer=<id>

• Override CableCARD manufacturer ID returned by the platform


PC Platform Configuration – Launcher

• platform_<os>.cfg• Platform-specific bootstrapper for the PC

platform• Launches

• PC Platform set-top emulator• 1 or more applications (in shared libs)

• OCAP• Native app (Blu-Ray Player)

• Located in $PLATFORMROOT


PC Platform Configuration – STB/Headend Emulator

• platform.cfg• Configuration parameters for UI, OOB,

frontpanel, backpanel, display, Headend emulation

• Configuration values can contain environment variables• $(<env_var>)

• Located in $PLATFORMROOT


Setting up Graphics Resolution

TV Screen size fromDISP.DEFAULT.CONFIG (mpeenv.ini)

Platform Window size fromRI.Emulator.TvScreen.widthRI.Emulator.TvScreen.height (platform.cfg)

Video scaled accordingto incoming video sizeand applicable DFC rule


Coherent Configurations

DISP.DEFAULT.CONFIG Configuration

0 640x480 1:1 graphics, 720x480 8:9 video, 640x480 1:1 background




4 640x480 4:3 graphics, 1920x1080 1:1 video, 1920x1080 1:1 background (with I-frame support)

5 960x540 1:1 graphics, 1920x1080 1:1 video, 1920x1080 1:1 background (with I-frame support)


CableCARD Emulation

• Very limited CableCARD emulation• Generic Features Only• PC Platform uses DRI to communicate with

CableCARD• $RICOMMONROOT/resources/GpnvsDatabaseFile.xml

• Values are either strings or base64 encoded binary from CCIF specification


Running the RI


runRI.sh

• Main execution script for the RI PC Platform– runRI.sh –help– Lots of options• ATE• Setup for test Xlets• Native debugging

– Located in $PLATFORMROOT


Logging and Debugging


Stack logging

• Stack logging verbosity managed in mpeenv.ini– Example: LOG.MPE.JAVA = ALL DEBUG

• Logging may affect performance/timing (reset to DEFAULT if problems encountered)

• Java stack code uses log4j – configurable via $OCAPROOT/bin/$OCATPTC/env/log4j.properties

• Useful links on Wiki – search for ‘logging’


Platform logging

• Platform code uses log4c to manage logging• Configuration found in

$PLATFORMROOT/log4crc• Useful links on Wiki – search for ‘logging’


Logging and IssueTracker

When attaching a log to IssueTracker• Ensure the log contains timestamps• Helpful if Java debug logging is enabled


Chainsaw screenshot


Java Stack debugging

• Possible to step through breakpoints in Java stack code, generate stack traces and thread dumps

• Stack trace, thread dumps available via jdb (included with the Sun JDK)

• To enable Java debugging, un-comment VMOPT19 & 20 in mpeenv.ini and start debugger or jdb

• Re-comment VMOPT 19 & 20 when done..


Platform debugging

• gdb can be used to generate a trace if the Platform terminates unexpectedly

• ./runRI.sh -gdb


Eclipse

• Eclipse .project and .classpath files for RI Stack code available from me– Java debugging– Native code debugging (not me)

• Debugging demonstration


Performance and Profiling


Eclipse

• PlatEval– Xlet contributed by Comcast/TVWorks.– Measures time for basic JVM operations• Array fills• Graphics operations• Fonts

• Profiling– Netbeans profiling support– See Wiki page

• OCAP specification hooks coming in 1.2


Application Signaling


XAIT – MPEG Sections

• Captured XAIT from real signaling source– Headend– Software tool

• $RICOMMONROOT/resources/fdc-files.txt– Forward Data Channel (DRI2.0 terminology for OOB data

pathway)– Filelist indicating MPEG2 section files to be “played out”– Actual MPEG2 section files must be located in

$RICOMMONROOT/resources/fdcdata• Playout interval specified in $PLATFORMROOT/platform.cfg

– RI.Platform.OOBTableRequestPeriod– File is read every interval

• Trigger signaling changes


XAIT – File-Based Signaling

• Provide all the components of XAIT/AIT signaling in file format– File should be located in the classpath• xait.properties• ait.properties• hostapp.properties

• See the wiki for a complete description of fields


Channel Maps, Tuners,Headend Video Service Emulation


PC Platform Emulation

• Channel Map– SCTE 65 SI

• Video Source– MPEG transport stream files

• SPTS• MPTS

– Live QAM modulated transport streams• HDHomerun

• Tuners– PC Platform can be configured to use either of these video

sources and respond to “tune” requests.– MPEG transport stream delivered to platform media

pipelines


Service Information (SCTE 65)

• The RI stack builds its channel map from the following tables– NIT

• CDS Subtable (Transport carriers)• MMS Subtable (Modulation Modes)

– SVCT– NTT

• SNS Subtable (Channel names)

• No file-based emulation for SI.– MPEG2 sections only

• $RICOMMONROOT/resources/fdc-files.txt– Same as XAIT

• Playout interval same as XAIT


Acquiring SI

• Capture from actual headend– CableLabs EYES tool– Other mechanism

• Tru2way Workbench• Others?


Video Sources

• PC Platform limitations– PC Platform only has MPEG-2 decoder– No audio decoding support– Non-encrypted streams only

• Configure number of “tuners” (simulataneous video sources)– $PLATFORMROOT/platform.cfg

• RI.Platform.numTuners• MPEG-2 Files

– VLC sends transport stream via localhost UDP connection– platform.cfg determines QAM carrier mapping– Can capture files from live QAM source using HDHomerun

• Live Source– HDHomerun decodes QAM modulated transport stream and

streams via localhost TCP


VLC Tuners

• Separate VLC process launched to stream TS file– $RICOMMONROOT/resources/<Win32/Linux>/VLC

• Configuration ($PLATFORMROOT/platform.cfg)– RI.Platform.ipAddr

• Set to 127.0.0.1– RI.Headend.TunerType = VLC– RI.Headend.tuner.x.TunerStreamerPort

• Port that VLC will listen for commands– RI.Headend.tuner.x.StreamerIp

• VLC process can run on a separate machine– RI.Headend.tuner.x.TunerRxPort

• Port the PC Platform will open to listen for transport stream packets– RI.Headend.tuner.x.tunerNum

• Not used


VLC Tuners <cont>

• When a platform “tune” request is received– VLC Process launched– VLC directed to stream a file based on the

“carrier map” in platform.cfg• RI.Headend.vlc.frequency.<Hz>_<QAM> = <file>

• Program numbers in transport stream file must match up with channel map (SCTE 65 data)


HDHomerun Tuners

• Command line utility used to set HDHomerun tuners and streaming parameters– $RICOMMONROOT/resources/<Win32/Linux>/HdHr/hdhomerun_config.exe

• Configuration ($PLATFORMROOT/platform.cfg)– RI.Platform.IpAddr

• Set to your PC’s IP– RI.Headend.TunerType = HDHR– RI.Headend.tuner.x.tunerNum

• Tuner ID on back of HDHomerun (0 or 1)– RI.Headend.tuner.x.tunerRxPort

• Port the PC Platform will open to listen for transport stream packets– RI.Headend.tuner.x.streamerPort

• HDHomerun DeviceID (bottom of HDHomerun). Specify as hex with 0x prefix.

– RI.Headend.tuner.x.streamerIp• Not used
