Presentation time stamps (PTS) are embedded in MPEG transport streams to precisely signal when each audio and video segment is to be presented, to avoid AV-sync errors. . However, these timestamps are often added after the video undergoes frame synchronization, format conversion and preprocessing, and thus the lip sync errors created by these operations will not be corrected by the addition ...
To correct audio video sync problems, the video processing circuitry outputs a DDO (digital delay output) signal, which carries information about the amount of delay the video signal experiences due to the video processing. The DDO may, for example, be provided by equipment which adheres to the SMPTE Audio to Video Synchronization Standard. The ...
Ford Sync (stylized Ford SYNC) is a factory-installed, integrated in-vehicle communications and entertainment system that allows users to make hands-free telephone calls, control music and perform other functions with the use of voice commands.

The iPhone 13 Mini features a 5.4-inch (137 mm) display with the same technology at a resolution of 2340×1080 pixels and a pixel density of about 476 PPI.
Video-signal generator. A video signal generator is a type of signal generator which outputs predetermined video and/or television oscillation waveforms, and other signals used in the synchronization of television devices and to stimulate faults in, or aid in parametric measurements of, television and video systems.
Zune devices featured preloaded audio and video content from various artists, including Wisin & Yandel, BT, The Thermals, Paul Oakenfold, and CSS. Limited edition, promotional, and employee-gift Zune devices also featured unique content of varying kinds (i.e. pictures, videos, music, and/or audio/video podcasts).
There are many ways of showing video sequences to experts and recording their opinions. A few of them have been standardized, mainly in ITU-R Recommendation BT.500-13 and ITU-T Recommendation P.910. The reason for measuring subjective video quality is the same as for measuring the mean opinion score for audio. Opinions of experts can be ...
The sync pulse is typically a sine wave of 50 or 60 Hz with an RMS amplitude of approximately 1 volt. [4] This double-system audio recording could then be transferred or "resolved" to sprocketed magnetic film, with sprocket holes that match one to one with the original camera film. These two sprocketed media could be run through a "Moviola" or ...
