PTP: Transport versus boundary clock in broadcast environment
The first four documents in the ST2110 standard suite, covering the transport of professional media over managed IP networks, have now been published. Unlike SMPTE 2022 streams where a complete SDI signal is encapsulated into one IP flow, ST2110 separates out the essence of the media into video, audio and metadata flows. Integral to the operation of ST2110 is the ability to re-synchronise these flows using PTP timestamps and to support legacy equipment through accurate reproduction of genlock. The ST2059 standard addresses the key timing parameters in such a system but consideration must also be given to the accurate transport of PTP signals throughout your IP network.
In the white paper published by Embrionix Corporation you will find useful information regarding the choice of topologies for PTP networks, especially as it applies to the use of transparent or boundary clocks

Furthermore Embrionix are currently shipping emSFP modules for converting SDI to IP using either SMPTE 2022-6/7 or ST2110 transport, for technical support, pricing or availability please contact us via the Embrionix page here.
