Abstract
Embodiments herein describe a common point of control of local clocks in endpoint devices in a media production studio that are synchronized using an IP-based synchronization protocol. In one embodiment, a master clock generator outputs a master clock signal which is distributed to the endpoint devices in the media production studio. The endpoint devices include local clock generators that convert the master clock into an adjusted clock. A clock manager provides a common point of control for the local clock generators in the endpoints. The clock manager includes an input/output (I/O) interface which enables an engineer to adjust the jam time of the local clock generators as well as adjust a delay used when outputting media content to another endpoint device.
