What is this BS EN 62503 - Synchronization of audio and video about?
BS EN 62503 discusses multimedia quality with a focus on the method of assessment of synchronization of audio and video.
BS EN 62503 provides a subjective (or perceptible) and statistical method of assessment of overall, or end-to-end, difference of delays between real world and reproduced scenes in terms of video and accompanying audio recorded in a medium.
Note: BS EN 62503 does not specify limiting values for those results obtained by the application of the provisions in BS EN 62503. It excludes applications to professional broadcast systems.
Who is BS EN 62503 - Synchronization of audio and video for?
BS EN 62503 on synchronization of audio and video is useful for:
- Audio equipment manufactures
- Audio programmers
- Music producers
- Music studios
- Other equipment that uses audio interface (television, phones)
Why should you use BS EN 62503 - Synchronization of audio and video?
Contemporary multimedia systems are realized by digital technology. Depending on what digital processing is being applied, time delays differ among medium channels for reproduction as perceptible stimulus for a human audience.
BS EN 62503 addresses the item using typical multimedia content such as bust shots of newscasters because of easiness in defining synchronization of audio and video. Since a range of perceptibly allowable miss-synchronization and sensitivity of human audience for lead and delayed audio against accompanied video depends on human sensation and the conditions for assessment, a clearly defined method of assessment of such characteristics should be standardized.
