Synchronization - Uses

Uses

• Film synchronization of image and sound in sound film.
• Synchronization is important in fields such as digital telephony, video and digital audio where streams of sampled data are manipulated.
• In electric power systems, alternator synchronization is required when multiple generators are connected to an electrical grid.
• Arbiters are needed in digital electronic systems such as microprocessors 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 transmissions contain synchronizers which allow the toothed rotating parts (gears and splined shaft) to be brought to the same rotational velocity before engaging the teeth.
• Time codes are often used as a means of synchronization in film, video, and audio applications.
• Flash photography, see Flash synchronization
