Emerging Technology Trends Report Dante Q-LAN EBU N/ACIP
Emerging Technology Trends Report AES Technical Committee on Network Audio Systems November 2011 Editor, Tim Shuttleworth; [email protected] This document is a compilation of contributions from numerous members of the Technical Committee on Networked Audio Systems. The committee has identified the following important topics related to emerging audio networking technologies. Technologies which have emerged since the last published Emerging Trends Report from the committee in 2007 are included. To provide structure to the report items are discussed in order of their maturity; commercialized technologies implemented in products available for purchase being discussed first and embryonic concepts in early development come up last. Other categorizations referred to in this document are consumer market orientation versus professional market focus, as well as media transport methods versus command and control protocols. Dante Dante is a media networking solution developed by Audinate. In addition to providing basic synchronization and transport protocols Dante provides simple plug and play operation, PC sound card interfacing via software or hardware, glitch free redundancy, support for AVB and support for routed IP networks. The first Dante product arrived in 2008 via a firmware upgrade for the Dolby Lake Processor and since then many professional audio and broadcast manufacturers have adopted Dante. From the beginning Dante implementations have been fully IP based, using the IEEE 1588-2002 standard for synchronization, UDP/IP for audio transport and are designed to exploit standard gigabit Ethernet switches and VoIP-style QoS technology (e.g. Diffserv). Dante is evolving with new networking standards. Audinate has produced versions of Dante that use the new Ethernet Audio Video Bridging (AVB) protocols, including IEEE 802.1AS for synchronization and RTP transport protocols. -
XMOS for AVB Ethernet Based Networking for Audio/Video
Only a few years ago, computer networks were complex beasts tended by special acolytes and running on different standards. Today they have become commonplace in many homes and offices, simply plugged together using Ethernet technology. The same revolutionary change is coming for Audio/Video (AV) networking, as AVB (Audio XMOS for AVB: Video Bridging) products that run over the same network, Ethernet based networking begin to enter the market. for Audio/Video Putting together networks of AV equipment for professional and consumer use, or for use in How Ethernet Works vehicles, is about to become simpler while also Within Ethernet, data is transmitted between delivering better quality. No longer will devices (such as a computer and a printer) in specialist connectors and cables be needed to packets. Each packet carries one or more create a rats' nest of connectivity. Instead addresses for its destination. Like a postal packet traversing the postal system, the network has no Audio Video Bridging (AVB), a set of knowledge of what is in the packet, but uses the international standards, will make setting up address to pass the packet to the next point in the and managing networks almost as simple as network. just plugging together the different elements. In an Ethernet based network, each endpoint Sound and video sources will be mixed and (computer, storage element, printer etc.) is distributed to screens and speakers, with high identified by a unique address and has a single quality, low latency and tight synchronization. connection to the network, through an Ethernet Furthermore, the connectors and cables are switch. -

Public Address System Network Design Considerations
AtlasIED APPLICATION NOTE Public Address System Network Design Considerations Background AtlasIED provides network based Public Address Systems (PAS) that are deployed on a wide variety of networks at end user facilities worldwide. As such, a primary factor, directly impacting the reliability of the PAS, is a properly configured, reliable, well-performing network on which the PAS resides/functions. AtlasIED relies solely upon the end user’s network owner/manager for the design, provision, configuration and maintenance of the network, in a manner that enables proper PAS functionability/functionality. Should the network on which the PAS resides be improperly designed, configured, maintained, malfunctions or undergoes changes or modifications, impacts to the reliability, functionality or stability of the PAS can be expected, resulting in system anomalies that are outside the control of AtlasIED. In such instances, AtlasIED can be a resource to, and support the end user’s network owner/manager in diagnosing the problems and restoring the PAS to a fully functioning and reliable state. However, for network related issues, AtlasIED would look to the end user to recover the costs associated with such activities. While AtlasIED should not be expected to actually design a facility’s network, nor make formal recommendations on specific network equipment to use, this application note provides factors to consider – best practices – when designing a network for public address equipment, along with some wisdom and possible pitfalls that have been gleaned from past experiences in deploying large scale systems. This application note is divided into the following sections: n Local Network – The network that typically hosts one announcement controller and its peripherals. -
Secure Remote Service Execution for Web Media Streaming
Secure Remote Service Execution for Web Media Streaming vorgelegt von Dipl.-Ing. Alexandra Mikityuk geb. in Leningrad, UdSSR von der Fakultät IV – Elektrotechnik und Informatik der Technischen Universität Berlin zur Erlangung des akademischen Grades Doktor der Ingenieurwissenschaften - Dr.-Ing. - genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. Thomas Magedanz, Technische Universität Berlin Gutachter: Prof. Dr. Jean-Pierre Seifert, Technische Universität Berlin Gutachter: Prof. Dr. Jean-Claude Dufourd, ParisTech Gutachter: Prof. Dr.-Ing. Ina Schieferdecker, Technische Universität Berlin Tag der wissenschaftlichen Aussprache: 29. August 2017 Berlin 2017 D 83 Abstract Through continuous advancements in streaming and Web technologies over the past decade, the Web has become a platform for media delivery. Web standards like HTML5 have been designed accordingly, allowing for the delivery of applications, high-quality streaming video, and hooks for interoperable content protection. Efficient video encoding algorithms such as AVC/HEVC and streaming protocols such as MPEG-DASH have served as additional triggers for this evolution. Users now employ Web browsers as a tool for receiving streaming media and rendering Web applications, and browsers have been embedded into almost every kind of connected device. The drawback of these technical developments and quick rate of user adoption is that modern Web browsers have introduced significant constraints on devices’ capabilities. First, the computational requirements have risen continuously, resulting in a cycle where modern devices can be nearly outdated after a year or two. Second, as the integration of browser technologies is a complicated matter, not every platform provides the same performance. Different Operating Systems (OSs), chipsets and software engines are the main reasons for this difference in performance. -

Computing Science
UNIVERSITY OF NEWCASTLE University of Newcastle upon Tyne COMPUTING SCIENCE A Trust-economic Perspective on Information Security Technologies S. E. Parkin and A. van Moorsel TECHNICAL REPORT SERIES No. CS-TR-1056 October, 2007 TECHNICAL REPORT SERIES No. CS-TR-1056 October, 2007 A Trust-economic Perspective on Information Security Technologies Simon Edward Parkin and Aad van Moorsel Abstract This report surveys existing enterprise technologies and products available to control access to confidential digital data. We survey USB access control solutions, digital rights management software, disk encryption techniques and operating system solutions. We compare the various technologies with respect to granularity and extent of administrative control, platform coverage, user education features, and accommodation of data use outside the boundaries of the company network. The researched technologies allow restrictions to be placed on copying, editing, viewing and printing from within various software applications, provide auditing options and prevent outsider access through encryption. Several of the mentioned technologies offer training and education options, informing users as to the reasoning of access control events as they occur and educating them about the permissions that apply to them. A serious drawback of many of the technologies is the central administration it requires. We are interested in cost trade-off, to be able to make trust-economic decisions. The cost of software deployment is linked to the features that each product provides, where finer granularity of device and file content control, encryption and user education implies that per-user purchase cost increases. © 2007 University of Newcastle upon Tyne.
