Detailed Description

A wrapper class for C++ DuckContext.

Constructor & Destructor Documentation

DuckContext()

io.tsduck.DuckContext.DuckContext ( Report  report )

inline

Constructor.

Parameters

report

The report object to use. If null, reports are sent to standard error.

Member Function Documentation

delete()

native void io.tsduck.DuckContext.delete

(

)

Delete the encapsulated C++ object.

Reimplemented from io.tsduck.NativeObject.

setDefaultCharset()

native boolean io.tsduck.DuckContext.setDefaultCharset

(

String

charset

)

Set the default character set for strings.

The default should be the DVB superset of ISO/IEC 6937 as defined in ETSI EN 300 468. Use another default in the context of an operator using an incorrect signalization, assuming another default character set (usually from its own country) or in the context of mixed standards (ISBD/DVB for instance).

Parameters

charset

The new default character set name or an empty string to revert to the default.

Returns

True on success, False if charset is invalid.

setDefaultCASId()

native void io.tsduck.DuckContext.setDefaultCASId

(

short

cas

)

Set the default CAS id to use.

Parameters

cas	Default CAS id to be used when the CAS is unknown.

setDefaultPDS()

native void io.tsduck.DuckContext.setDefaultPDS

(

int

pds

)

Set the default private data specifier to use in the absence of explicit private_data_specifier_descriptor.

Parameters

pds	Default PDS. Use zero to revert to no default.

addStandards()

native void io.tsduck.DuckContext.addStandards

(

int

mask

)

Add a list of standards which are present in the transport stream or context.

Parameters

mask	A bit mask of standards.

standards()

native int io.tsduck.DuckContext.standards

(

)

Get the list of standards which are present in the transport stream or context.

Returns

A bit mask of standards.

resetStandards()

native void io.tsduck.DuckContext.resetStandards

(

int

mask

)

Reset the list of standards which are present in the transport stream or context.

Parameters

mask	A bit mask of standards.

setTimeReferenceOffset()

native void io.tsduck.DuckContext.setTimeReferenceOffset

(

long

offset

)

Set a non-standard time reference offset.

In DVB SI, reference times are UTC. These SI can be reused in non-standard ways where the stored times use another reference. This is the case with ARIB and ABNT variants of ISDB which reuse TOT, TDT and EIT but with another local time reference.

Parameters

offset

Offset from UTC in milli-seconds. Can be positive or negative. The default offset is zero, meaning plain UTC time.

setTimeReference()

native boolean io.tsduck.DuckContext.setTimeReference

(

String

name

)

Set a non-standard time reference offset using a name.

Parameters

name	Time reference name. The non-standard time reference offset is computed from this name which can be "JST" or "UTC[[+|-]hh[:mm]]".

Returns

True on success, False if name is invalid.

Member Data Documentation

nativeObject

long io.tsduck.NativeObject.nativeObject = 0

protectedinherited

The address of the underlying C++ object.

It is normally accessed by native methods only.
