Abstract:
1. A network suitable for transporting media packets, the network comprising: a master clock device to generate a system time signal for the network, wherein the system time signal and media packets are both communicated in a same band on the network; a plurality of network devices interconnected such that the plurality of network devices can send media packets to the plurality of network devices, and to receive media packets from the plurality of network devices; wherein the plurality of network devices are configured to receive media signals from a media device, to transmit media signals to a media device, or to do both and wherein at least one of the plurality of network devices is configured to receive and transmit media signals to a media device; wherein, the plurality of network devices are coupled to the master clock device and uses the system time signal and a network time protocol to generate a local clock signal synchronised to the system time signal for both rate and offset, the local clock signal governing both the rate and offset of the received or transmitted media signals; and wherein a media clock signal is synthesized from at least the local clock signal, such that the media clock signal governs the rate and offset at which media signals are received or transmitted.
