Patent number: 10771290Abstract: 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.Type: GrantFiled: August 22, 2019Date of Patent: September 8, 2020Assignee: AUDINATE PTY LIMITEDInventors: Aidan Williams, Christopher Graham Ware

Patent number: 10536499Abstract: 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 time are written to the same location in the buffer. Both media packet streams are simply processed all the way to the buffer 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.Type: GrantFiled: November 28, 2017Date of Patent: January 14, 2020Assignee: Audinate Pty LimitedInventors: Aidan Williams, Andrew White

Patent number: 10461872Abstract: 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 synchronized 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.Type: GrantFiled: August 31, 2018Date of Patent: October 29, 2019Assignee: Audinate Pty LimitedInventors: Aidan Williams, Varuni Witana

Patent number: 10419506Abstract: A system for providing networked access to media signals, the system comprising at least one virtual media card, at least one media interface, an advertisement and discovery module, a network interface to a common network and a reference clock. The virtual media card is configured to interface with at least one application and the media interface is configured to interface with at least one physical media card. The virtual media card and the media interface communicate with the system using the common reference clock. The advertisement and discovery module is 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 and to make I/O channels of the at least one media card and the I/O channels of the at least one application available to the system and the common network.Type: GrantFiled: June 10, 2015Date of Patent: September 17, 2019Assignee: Audinate Pty LimitedInventors: Aidan Michael Williams, James Henry Westendorp

Patent number: 9979767Abstract: This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. The network (104) is comprised of at least a transmitter device (110) and a receiving device (112). The controllers (122) and (126) of these devices handle the exchanging of configuration messages between the devices (110) and (112). Using the invention, the user is not required to manually configure the processor to receive media packet streams. Instead, a controller (126) of a receiving device (112) operates to receive information on a user selection of media channels and automatically configure the processor of the transmitter device. Further, the receiving device (112) is able to receive media channels using both unicast and multicast protocols. Media channels can be given textual labels which are unique on the unique (104) and easily identify to the user the actual source of the media channel.Type: GrantFiled: September 18, 2015Date of Patent: May 22, 2018Assignee: Audinate Pty LimitedInventors: Aidan Williams, Andrew White
