IRIG standard 212-00 defines a different time-code, based on RS-232-style asynchronous serial communication. The timecode consists of ASCII characters, each transmitted as 10 bits: 1 start bit; 7 data bits; 1 odd parity bit; 1 stop bit; The on-time marker is the leading edge of the first start bit.
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes).This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
A timecode (alternatively, time code) is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production , show control and other applications which require temporal coordination or logging of recording or actions.
SMPTE timecode signal (A logic value 1 is expressed by a transition at the midpoint of a period. A logic value 0 is expressed by the absence of such a transition.) compared to the outwardly-similar Manchester code (A logic value 0 is expressed by a high-to-low transition, a logic value 1 by low-to-high transition at the midpoint of a period).
This converts 30 frame/second time code to the 29.97 frame/second NTSC standard. Bit 15, the color framing bit, is set to 1 if the time code is synchronized to a (color) video signal. The frame number modulo 2 (for NTSC and SECAM ) or modulo 4 (for PAL ) should be preserved across cuts in order to avoid phase jumps in the chrominance subcarrier .
In communications messages, a date-time group (DTG) is a set of characters, usually in a prescribed format, used to express the year, the month, the day of the month, the hour of the day, the minute of the hour, and the time zone, if different from Coordinated Universal Time (UTC).
This converts 30 frame/second time code to the 29.97 frame/second NTSC standard. Bit 11, the color framing bit, is set to 1 if the time code is synchronized to a color video signal. The frame number modulo 2 (for NTSC and SECAM ) or modulo 4 (for PAL ) should be preserved across cuts in order to avoid phase jumps in the chrominance subcarrier .
When there is a jump in the time code, a single full-time code is sent to synchronize attached equipment. This takes the form of a special global system exclusive message: F0 7F 7F 01 01 hh mm ss ff F7. The manufacturer ID of 7F indicates a real-time universal message, the channel of 7F indicates it is a global broadcast.
