SignalGroupAssetType

SignalGroupAssetType is an extension of the CableLabs 3 AssetType. Implementers which do not deal with CableLabs Assets may safely ignore this type.

.	Name	Use	Type	Annotation
Based on:			core:AssetType
Element	SignalPoint	optional multiple	SignalPointType	One or more SignalPoint elements that exist in an asset.
Element	SignalRegion	optional multiple	SignalRegionType	One or more SignalRegion elements that exist in an asset.

BinarySignalType

.	Name	Use	Type	Annotation
Based on:			xsd:base64Binary
Attribute	signalType	required	xsd:string pattern=SCTE35\|EISS\|binary\|private:.+	Specifies the type of signal contained in this element.

SignaledPointInfoType

Specify information about a signaled point in a stream. The information may specfy information about an anticipated signal or be populated after the signal arrives.

.	Name	Use	Type	Annotation
Attribute	acquisitionSignalID	optional	xsd:string minLength=1	The authoritative ID of the signal. This ID may be carried forward from the acquisition sytem to other system element in the delivery platform.
Attribute	ANY	optional	##any	In addition to the attributes defined, a signaled point may include additional, custom attributes as needed by the application.
Element	SignalValidityTimeRange	optional		Specify the time range the signal will be considered valid. For example, an SCTE 35 cue message may only be considered valid during a defined time range.
Element	SCTE35PointDescriptor	optional	SCTE35PointDescriptorType	For SCTE 35 cue messages with additional descriptive data the following can be used for matching incoming signals and/or populated with authoritative descriptive data received. For example, a match may be done on SCTE 35 Segmentaiton Descriptor information, on "providerAvailId" in the AvailDesciptorInfo on the SpliceInsert or various other means.
Element	StreamTimes	optional	StreamTimesType	Authoritative StreamTimes contains one or more time values that are generated and interpreted by the underlying subsystem. While implementation specific, this data is intended to be passed as is through intervening systems unaltered.
Element	AcquisitionPointInfo	optional multiple	AcquisitionPointInfoType	One or more AcquisitionPointInfo items can be passed in the structure. One use of this structure is in the case where signals for the same point are acquired from multiple acquisiiton points. Typically only one of the signals will be applied while multiple signals are actually received and communicated between subsystems. This structure allows a system to pass the data for all acquisition points. A diagnostic system is one consumer of such a fully populated structure.
