Definitions, Acronyms and Abbreviations Table 1: Table of Terminology Term Definition DDS domain Acronym: Data Distibution service Essence A general term used to describe a media component; video, audio or metadata. Flow Sequence of RTP packets of a single essence. The term Flow can be considered synonymous with Stream. IP The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. IPMI The Intelligent Platform Management Interface (IPMI) is a set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system's CPU, firmware (BIOS or UEFI) and ope rating system. Multicast enabled In computer networking, multicast (one-to-many or many-to-many distribution) is group communication IT network where information is addressed to a group of destination computers simultaneously. NTP Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. PTP The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network, it achieves clock accuracy in the sub -microsecond range, making it suitable for measurement and control systems. QFSP Quad Small Form-factor Pluggable The QSFP is a compact, hot-pluggable transceiver used for data communications applications. It interfaces networking hardware to a fibre optic cable or active or passive electrical copper connection. It is an industry format jointly developed and supported by many network component vendors, allowing data rates from 4x4 Gbit/s.

Introduction This guide is designed to give simple step-by-step instructions explaining how to use the Audio Live IP router. Audio Live is a multi-channel audio routing and processing solution for the IP domain. It supports AES67 / RFC3190(L24) / SMPTE2110-30 streams and offers a powerful 2048x2048 channel routing matrix. Routing of audio streams requires that input audio streams be synchronous, PTP timestamps must be present in the extended headers and the RTP timestamps must be present and locked to the PTP timestamps for successful operation. Where inputs are encountered that are asynchronous, Audio Live offers the ability to synchronise up to 16 asynchronous audio stream inputs. Audio Live offers the unique ability to configured as an asymmetric router. The input and output can be independently configured from the following configurations: Table 2: Asymmetric Routing Configurations Routing Configurations 32 Streams x 64 Channels 64 Streams x 64 Channels 64 Streams x 32 Channels 128 Streams x 16 Channels 192 Streams x 8 Channels 8 x 64, 32 x 16, 128 x 8 Channels 8 x 64, 64 x 16, 64 x 8 Channels 16 x 64, 16 x 16, 96 x 8 Channels 16 x 64, 32 x 16, 64 x 8 Channels 16 x 64, 56 x 16, 32 x 4 Channels Audio Live offers an input realignment buffer , enabling various upstream transmission delays present on each input stream to be compensated for and aligned with the designated reference stream. The maximum size of the input tolerance buffer ranges between 20ms and 1 seconds depending on which router input configuration is selected. The Timestamp tolerance is affected by the System Input and Output channel configuration - see Table 2 in Appendix D. The reference stream can be manually forced or an automatic mode can be used. Timestamps are then used to synchronize all the flows and provide flow control at the output. From a time stamp perspective Audio Live is completely transparent. Additional channel delay can be added to the input and output channels if required up which ranges between 2 seconds and 5 seconds before the audio router again depending on the System Input and Output channel configuration – see Table 2 in Appendix D. The control application for Audio Live and the GV Live software, is RollCall Control Panel (RollCall Lite may be used and is available as a free download). As this is not a RollCall/RollCall Lite tutorial, it is assumed that RollCall Lite is already installed and operational. For larger systems we recommend the use of GV’s IP Routing Control Server (V9.8.14 or above) to configure spigots and the Audio Live internal cross point. Version Number: 1.4 © 2018 GV Page 6 of 85 Audio Live User Guide 3. System Requirements / Prerequisites 1. IT Network: In order to successfully use Audio Live, a multi-cast enabled IP network is required. To send/receive ‘AES 67’ Audio Stream, Audio Live must have the same DDS Domain ID as the source/destination devices. 2. RollCall Lite Control Panel: Audio Live is configured and controlled using RollCall Lite. At the time of writing, the current RollCall Control Panel release version is V4.16.37 (June 2018). It is recommended that this software suite is kept up to date. http://www.grassvalley.com/downloads/routers/rollcall_v4.16.37/ 3. IP Routing Controller: In order to successfully and easily create specific routes we recommend the use of GV’s IP Routing Controller. 4. Audio Live License: For successful operation of Audio Live a valid license is required. 5. Input Streams: For synchronous input streams, PTP timestamps must be present in the extended headers and the RTP timestamps must be present and locked to the PTP timestamps. Up to 16 asynchronous input streams can be received utilizing the ‘synchronise’ feature. 4. GV Live Architecture The GV Live software consists of a Host, Agent and License Server. The GV Live Host manages the GV Live Agents. Typically there would be one host per physical compute instance. From a RollCall perspective, the GV Live Host can be considered as a virtual IQ frame. GV Live Agents are spawned by the Host and adopt a product type based on the nominated product license. Each agent has its own unique RollCall address just like a module would in a frame and can therefore be considered as a virtual slot. The License Server is the local daemon that manages the product license/licenses. The daemon must be present on start for the product to successful use of the product. If for any reason the license disappears there is a 7 day grace period before the product will stop working. Page 7 of 85 © 2018 GV Version Number: 1.4 Audio Live User Guide 5. The Console 5.1 Introduction Audio Live application runs on Linux Ubuntu OS. A Console is provided to offer simplified configuration of key elements of the system. Using the Console the following items can be configured:  Network – NIC 1 is defined to have a Static IP and cannot be set to DHCP. NIC’s 2, 3 & 4 may be configured to be either Static IP or DHCP.  The time and set may be set.  An upgrade process may be initiated.  A new license may be installed.  The Status of the system may be displayed.  Operational Logs may be retrieved.  The Server may be power-cycled.  The Server may be shut down. 5.2 Accessing the Console To access the Console connect a monitor to the on-board VGA and connect a USB mouse and keyboard. 1. Connect a Monitor, Keyboard and Mouse to the Audio Live Host machine: Version Number: 1.4 © 2018 GV Page 8 of 85 Audio Live User Guide 2. Connect a Network cable to the Server: Note that there are 5 network ports. IPMI network port NIC 1 NIC 2 NIC 3 NIC 4  NIC 1 (eno1) is factory configured with the default Static IP Address and /30 subnet mask: 192.168.0.1/30 NOTE - this port maybe set to another static IP address, mask and gateway but cannot be set to DHCP.  NIC 2 (eno2) is factory configured as DHCP. This port maybe configured as static or DHCP.  NIC 3 (ens1f1) - second Mellanox ConnectX4 port and is factory configured with a static address and subnet mask  NIC 4 (ens1f0) - first Mellanox port ConnectX4 port and is factory configured with a static address and subnet mask  IPMI port may be ignored at this point (see Appendix A, below). 3. Boot up the Audio Live host machine. Once the boot sequence has completed, to access to the Console type:  Alt F2 The Console will now appear: Note that the SAM Live software version is reported. Configurable items Page 9 of 85 © 2018 GV Version Number: 1.4 Audio Live User Guide 5.2.1 Configure Network Using the up/down arrows on the keyboard, highlight the item to be configured. In this case: Configure Network Press return and the Network Configuration menu will now be displayed: Note that in the Console:  NIC 1 equates to eno1 *  NIC 2 equates to eno2  NIC 3 equates to ens1f1 ConnectX4 - Port 2  NIC 4 equates to ens1f0 ConnectX4 - Port 1 * This port maybe set to another static IP address, mask and gateway but cannot be set to DHCP.
