Non-drop frame time code
| CCTV glossary (глоссарий терминов по видеонаблюдению) |
- Smpte time code format that continuously counts a full 30 frames
- Smpte time code format that continuously counts a full 30 frames per second. because ntsc video does not operate at exactly 30 frames per second, non-dropframe time code will count 108 more frames in one hour than actually occur in the ntsc video in one hour. the result is incorrect synchronization of time code with clock time. drop-frame time code solves this problem by skipping or dropping 2 frame numbers per minute, except at the tens of the minute count.

Continuously, английский
Synchronization, английский
- Rfc 793 and many others
- Синхронизация
- The process of keeping two devices or software systems precisely locked together, typically through the use of smpte, midi time code, or mc/spp standards. an example is keeping a sequencer precisely locked to a tape deck, maintaining the same location and speed.
- The matching of timing between computers on a network, or between components of a computer, so that all are coordinated.
- The process by which dpm transfers changes from the protected server to the dpm server, and applies the changes to the replica of the protected volume.
- The process of reconciling the differences between data stored in one location and a copy of the same data stored in another location.
Continuous, английский
- Непрерывный
- Непрерывный; длительный; продолжающийся
- A продолженный, дли- тельный, непрерванный form, future, past, present contoid n контоид
- Непрерывный, неразрывный, сплошной, неразрезной (об элементах конструкции)

Drop-fram time code, английский
- Smpte time code format that continuously counts 30 frames per second,
- Smpte time code format that continuously counts 30 frames per second, but drops two frames from the count every minute except for every tenth minute (drops 108 frames every hour) to maintain synchronization of time code with clock time. this is necessary because the actual frame rate of ntsc video is 29.94 frames per second rather than an even 30 frames.
