Time Synchronization of Spatial Separated Areas for AV-Production

For Audio and Video (AV) Production, time synchronization between different devices is an important part to achieve a high-quality AV production. A well-established method for synchronizing devices is the use of clock signals like wordclock, which might not be a convenient solution when the spatial distance between devices increases. This work is aiming to introduce to the possibility to use an IP-based standard to perform the time synchronization between different devices: IEEE 1588 Precision-Time-Protocol (PTP). Therefore the protocol is evaluated according to his performance under different network conditions using a network emulator and a test-scenario through a Wide-Area-Network. The performance of the time synchronization using PTP shows promising results.
