How you shouldn't just look at IP technologies in broadcast but also look at how off-the-shelf IT equipment can be used. Presented at NAB BEITC Engage! 2017
iDiff 2008 conference #01 IP-Racine : Cinema production infrastructure on 10G...Benoit Michel
Today, we have a bunch of interfaces on production devices
There is no interoperability with IT based post units
Common equipment connection technology is restricted to
3Gbit/s, but 10Gbit/s or even more already required
We demonstrate a validated future strategic interface
technology for power sensitive applications and long
distances
IP-Racine is sponsored by the European Commission 6th Framework Programme. see www.ipracine.org for details.
Esta charla es acerca de las lecciones aprendidas operando el servicio SIP2SIP.info, una oferta para cuentas SIP gratuitas creada en el año 2004 usando software y estándares abiertos, incluye: Direccionamiento y numeración, Proxy SIP frente a diseño B2B, Aplicaciones más allá de VoIP, NAT: mejores prácticas, Mejores prácticas anti-fraude, Datos y Almacenamiento de contraseñas.

This case study showcases Mistral’s capability in designing a flexible
and easy to upgrade VoIP Radio Gateway solution, interoperable with
all types of radio communications including conventional radios,
TETRA and TETRAPOL terminals. This IP Radio Gateway solution is
an exclusive and protected design for Mistral’s European customer,
Amper.
OpenVLC is an open-source, software-defined, flexible, low-cost Visible Light Communication platform. The software solution is implemented as a Linux driver that can communicate directly with the cape and the Linux networking stack.Visible Light Communication, sometimes also referred to as “LiFi" uses standard off-the-shelf visible light LEDs to transmit data using the visible light spectrum.

IMA/Thales EchoVoice (VOIP) for OpenSimulator Presentation at OSCC19Lisa Laxton
IMA/Thales EchoVoice (VOIP) for OpenSimulator
Frank Rulof, Seth Nygard, Lisa Laxton, Natacha Bru
Presentation Abstract: This presentation from Infinite Metaverse Alliance® (IMA) and Thales Group discusses progress towards improving open source code used in a self-hosted secure voice solution called EchoVoice. This is an alternative to ViVox which is commonly used for voice communication between avatars in OpenSimulator regions. The discussion is focused on the development work done to provide a modernized solution for HyperGrid-enabled regions as well as planned enhancements not currently available. The work of IMA and Thales is in general directed toward broadening use of the Metaverse for Public, Education, Industry and Government sectors but the community as a whole benefits from open source.
Target Audience & Outcomes: Participants from the OpenSimulator Community at large will learn about enhancements, features, and improvements IMA and Thales are working on together to deliver an open source solution that meets the needs of a broader OpenSimulator community.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

Session Initiation Protocol (SIP)
• An IETF-defined open signaling protocol, widely used for
controlling multimedia communication sessions such as voice and
video calls over Internet Protocol (IP).
• Can be used for creating, modifying and terminating two-
party (unicast) or multiparty (multicast) sessions consisting of
one or several media streams.
• Modification can involve changing addresses or ports, inviting
more participants, and adding or deleting media streams.
• Mercury Interface Unit would only accept a media stream if it
knows the IP address in advance
• Incoming IP address must be manually set up in advance
• Impossible with DHCP devices
