  • Patent number: 8767778
    Abstract: A system for synchronizing unrelated information or reference signals originating from multiple sources. The signals may be in different signal formats or subject to different delays at a receiving device. The system may include a master reference time generator connected to at least one of a plurality of slave reference signal generators via a packet network. The master reference time generator may include a master reference time counter and a sampling device for sampling the master reference time counter. The master reference time generator may encode time data in master reference time packets and feed these packets into the packet network. The slave reference signal generator(s) is adapted to accept the encoded time data as an input to generate a reference signal, the phase of which is calculated based on the time elapsed since an initial time point.

  • Patent number: 8095615
    Abstract: A system replaces the current “Genlock” reference signals and distribution architectures used in media and broadcasting use an IP network and distributed timekeeping service, such as ISO/IEC 61588 or IEEE1588. In such a system, a master and multiple slave devices are used to distribute precision time and phase information to synchronize equipment and systems. The method described herein allows the generation of a signal standard and format with a single distribution system. In addition, the method allows this distribution to be accomplished over an IP network despite the non-deterministic performance of such networks. The method also allows the deterministic generation of signals at slave devices.
