Editing Synchronization (section)

== Uses ==
Synchronization is important in [[digital telephony]], video and [[digital audio]] where streams of sampled data are manipulated. Synchronization of image and sound was an important technical problem in [[sound film]]. More sophisticated film, video, and [[sound|audio]] applications use [[time code]] to synchronize audio and video.<ref name=":1" /> In movie and television production it is necessary to synchronize video frames from multiple cameras. In addition to enabling basic editing, synchronization can also be used for [[3D reconstruction]]<ref>Moore, Carl, et al. "[https://ieeexplore.ieee.org/abstract/document/5636714/ Synchronization of images from multiple cameras to reconstruct a moving human]." 2010 IEEE/ACM 14th International Symposium on Distributed Simulation and Real Time Applications. IEEE, 2010.</ref>

In [[electric power]] systems, [[alternator synchronization]] is required when multiple generators are connected to an electrical grid.

[[Arbiter (electronics)|Arbiters]] are needed in digital electronic systems such as [[microprocessor]]s to deal with asynchronous inputs.  There are also electronic digital circuits called ''synchronizers'' that attempt to perform arbitration in one clock cycle.  Synchronizers, unlike arbiters, are prone to failure.  (See [[metastability in electronics]]).

[[Encryption]] systems usually require some synchronization mechanism to ensure that the receiving cipher is decoding the right bits at the right time.

Automotive [[transmission (mechanics)|transmissions]] contain [[synchromesh|synchronizers]] that bring the toothed rotating parts (gears and splined shaft) to the same rotational velocity before engaging the teeth.

[[Flash synchronization]] synchronizes the [[Flash (photography)|flash]] with the [[Shutter (photography)|shutter]].

Some systems may be only approximately synchronized, or [[plesiochronous]]. Some applications require that relative offsets between events be determined. For others, only the [[Partially ordered set|order]] of the event is important.<ref name="Nolte" />
