    摘要： A networked system is provided for transporting digital media packets, such as audio and video. The network includes network devices interconnected to send and receive packets. Each network device can receive and transmit media signals from media devices. A master clock generates a system time signal that the network devices use, together with 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 governs both the rate and offset of the received or transmitted media signals. The system, which can be implemented using conventional network equipment enables media signals to be transported to meet quality and timing requirements for high quality audio and video reproduction.

    摘要： This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. In particular, the invention concerns the transmitting and receiving of redundant media packet streams. Samples are extracted from a first and second media packet stream. The extracted samples are written to a buffer based on the output time of each sample. Extracted samples having the same output in time are written to the same location in the buffer. Both media packet streams are simply processed all the way to the bugger without any particular knowledge that one of the packet streams is actually redundant. This simplifies the management of the redundant packet streams, such as eliminating the need for a “fail-over” switch and the concept of an “active stream”, the location is the storage space allocated to store one sample. The extracted sample written to the location may be written over another extracted sample from a different packet stream previously written to the location. These extracted samples written to the same location may be identical.

    摘要： A system for providing networked access to media signals, the system comprising at least one virtual media card configured to interface with at least one application that produces and/or consumes media signals, and/or at least one media interface configured to interface with at least one physical media card that produces and/or consumes media signals. The system may also comprise a network interface configured to enable the system to exchange media signals with other devices on a common network, and a reference clock configured to provide a common clock signal to the at least one virtual media card, the at least one media interface, and the common network. An advertisement and discovery module configured to identify when the at least one application is started and/or stopped and when the at least one media card is attached and/or detached from the system may also be provided. The advertisement and discovery module is configured to: (i) make I/O channels of the at least one media card available to the system and the common network, and (ii) make I/O channels of the at least one application available to the system and the common network.

    摘要： Systems, methods, and processor readable media for distributing digital data and electrical power to a plurality of devices over high-impedance cables are disclosed. Certain embodiments include a gateway device connected to a power source, a first device connected to the gateway device by a cable, the cable being a high-impedance cable having at least two conductive paths, and wherein the first device receives electrical power and digital data from the gateway device via the cable over the same conductive path of the cable, a second device connected to the gateway device by the cable wherein the second device receives power and digital data from the gateway device via the cable over the same conductive path, and wherein the power source provides power to the first and second devices via the cable, and wherein the second device is connected to the gateway device through the first device via a daisy-chain topology.
