Detailed Description

eXtension Descriptor Id.

Most descriptors are identified by an 8-bit tag or DID. MPEG and DVB use the concept of "extension descriptor", with one single DID value and several extension descriptor ids. The XDID class encapsulates the two values to create a 16-bits unique identifier.

Note: this type is different from EDID. The XDID takes is intrinsicly linked to the descriptor content: the DID and the optional extension descriptor id. The EDID class is a wider concept which integrate contextual environments such as private descriptors or table-specific descriptor. The EDID is a superset of the XDID.

Constructor & Destructor Documentation

XDID()

Member Function Documentation

did()

DID ts::XDID::did ( ) const

inline

Get the descriptor id.

Returns

The descriptor id.

xdid()

DID ts::XDID::xdid ( ) const

inline

Get the extension descriptor id.

Returns

The extension descriptor id.

isExtensionMPEG()

bool ts::XDID::isExtensionMPEG ( ) const

inline

Check if the XDID is an MPEG extension descriptor.

Returns

True if the XDID is an MPEG extension descriptor.

isExtensionDVB()

bool ts::XDID::isExtensionDVB ( ) const

inline

Check if the XDID is a DVB extension descriptor.

Returns

True if the XDID is a DVB extension descriptor.

isExtension()

bool ts::XDID::isExtension ( ) const

inline

Check if the XDID is any form of extension descriptor.

Returns

True if the XDID is any form of extension descriptor.

toString()

UString ts::XDID::toString

(

)

const

Convert to a string object. Note: The XDID class does not implement StringifyInterface because we don't want to make it virtual and keep the instance size small, without vtable pointer.

Returns

This object, converted as a string.
