...

rh (8 bytes): A RecordHeader structure (section 2.3.1) that specifies the header for this record. Sub-fields are further specified in the following table.

Field

Meaning

rh.recVer

MUST be 0x0.

rh.recType

MUST be an RT_TimeVariant.

rh.recLen

MUST be an odd number.

type (1 byte): A TimeVariantTypeEnum enumeration that specifies the data type of this record. It MUST be TL_TVT_String.

timeRuntimeContext (variable): A UnicodeString that specifies the runtime context of the animation behavior of the corresponding time node. It MUST be a valid RUNTIME_CONTEXT as specified in the following ABNF (specified in [RFC5234]) grammar:

 RUNTIME_CONTEXT = CONTEXT_ATOM *(";" CONTEXT_ATOM) [";"]
 CONTEXT_ATOM = [RELATION_OPERATOR SPACE] APP_ABBREV [SPACE VERSION]
 RELATION_OPERATOR = GTE / GT / LTE / LT / NOT
 APP_ABBREV =  ("p" / "P") ("p" / "P") ("t" / "T")
 VERSION = DEC_NUMBER ["." DEC_NUMBER]
 DEC_NUMBER = 1*DIGIT 
 GTE = "g" "t" "e"
 GT = "g" "t"
 LTE = "l" "t" "e"
 LT = "l" "t"
 NOT = "!"
 SPACE = 1*" "

The length, in bytes, of the field is specified by the following formula:

 rh.recLen - 1
