+// class TimeCode
+//
+// 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
+// bgf1 boolean
+// bgf2 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
+// 24-frame 60-field 50-field
+// film television television
+//
+// 0 - 3 frame units frame units frame units
+// 4 - 5 frame tens frame tens frame tens
+// 6 unused, set to 0 drop frame flag unused, set to 0
+// 7 unused, set to 0 color frame flag color frame flag
+// 8 - 11 seconds units seconds units seconds units
+// 12 - 14 seconds tens seconds tens seconds tens
+// 15 phase flag field/phase flag bgf0
+// 16 - 19 minutes units minutes units minutes units
+// 20 - 22 minutes tens minutes tens minutes tens
+// 23 bgf0 bgf0 bgf2
+// 24 - 27 hours units hours units hours units
+// 28 - 29 hours tens hours tens hours tens
+// 30 bgf1 bgf1 bgf1
+// 31 bgf2 bgf2 field/phase flag
+//
+// User-defined data and control codes are packed as follows:
+//
+// bits field
+//
+// 0 - 3 binary group 1
+// 4 - 7 binary group 2
+// 8 - 11 binary group 3
+// 12 - 15 binary group 4
+// 16 - 19 binary group 5
+// 20 - 23 binary group 6
+// 24 - 27 binary group 7
