|

// A TimeCode object stores time and control codes as described
|

// in SMPTE standard 12M-1999. A TimeCode object contains the
|
||||
// following fields:
|
||||
//
|
||||
// Time Address:
|
||||
//
|
||||
// hours integer, range 0 - 23
|
||||
// minutes integer, range 0 - 59
|
||||
// seconds integer, range 0 - 59
|
||||
// frame integer, range 0 - 29
|

//
|

// Flags:
|
||||
//
|
||||
// drop frame flag boolean
|
||||
// color frame flag boolean
|

// field/phase flag boolean
|

// bgf0 boolean

// Binary groups for user-defined data and control codes:
|

//

// binary group 1 integer, range 0 - 15

// binary group 2 integer, range 0 - 15
|
||||
// ...
|
||||
// binary group 8 integer, range 0 - 15
|
||||
//
|
||||
// Class TimeCode contains methods to convert between the fields
|
||||
// listed above and a more compact representation where the fields
|
||||
// are packed into two unsigned 32-bit integers. In the packed
|
||||
// integer representations, bit 0 is the least significant bit,
|
||||
// and bit 31 is the most significant bit of the integer value.
|
||||
//
|
||||
// The time address and flags fields can be packed in three
|
||||
// different ways:
|

//
|

// bits packing for packing for packing for
