Desktop multimedia communications-breaking the chains

Abstract: It is noted that desktop multimedia is achievable today only if it is confined to a single personal computer using direct connections to laser disks, CD-ROMS, and other multimedia data sources. It is suggested that, in order to make multimedia data and services available to individuals connected via local and wide-area networks, special operating system hardware and software are needed. Special network management and services will be required to support bandwidth allocation, time (latency and synchronization) control, and data format conversion. The large bandwidths and real-time characteristics of multimedia affect network requirements. In addition, support in operating system software, dedicated hardware, application interfaces, and new internal buses are required to extend media off of the desktop and into the network. >

IMS: A Development and Deployment Perspective

Abstract: Providing an holistic approach to IMS technologies, IMS: A Development and Deployment Perspective explores service architecture for development and delivery of IMS services. Approaching IMS from the perspective of the user and the service provider it examines both the current state of deployment and future trends. The book offers a realistic view of IMS deployment to operators and service providers, giving practical examples, application cases and business models. It also presents IMS deployment strategies based on real-life deployment statistics from a live IMS test bed connected to an operator network and proof-of-concept applications including inter-operability trials and results. Focusing on IMS potential in terms of service creation, service composition and service provision the book discusses the ability of IMS to act not only as a service delivery framework, but also as a service integration framework. It presents the possible future of IMS in terms of convergence with Internet services, including discussions about integration with web technologies including the WIMS 2.0 initiative. The book enables a better understanding of how web technologies can complement the IMS service architecture and pioneer the post-IMS progress and success. Presents a novel service-oriented approach to IMS services and applications from a deployment perspective Places IMS in the context of the current telecom environment providing business models through WIMS 2.0 initiative Predicts the trends and potential future for the IMS evolution Provides a technical foundation to IMS principles and architecture Gives examples and solutions to the challenges of service creation and implementation and analyses deployment hurdles and interoperability trials Describes trends of convergence based on IMS and Web technologies

User equipment having web real time communication architecture

Abstract: A communication device configured to provide Web real-time communication (WebRTC) for interne protocol (IP) multimedia services utilizing one or more 3GPP protocols. The communication device can be configured to authenticate communication with one or more clients using one or more IP Multimedia Subsystem (IMS) credentials. The communication device can also be configured to convert communications between WebRTC and 3GPP protocols utilizing Traversal Using Relays around Network Address Translation (TURN) functionality implemented within the communication device.

Packet voice telephony apparatus and method

Abstract: According to the present disclosure, connectionless base IP protocol is leveraged to transfer streaming voice to a destination telephony device. As such, the disclosed IP telephony peripheral adjunct to a computer includes an interface to the computer, a controller and memory specifying the destination IP address, a packetizer coupled to the controller and memory for packetizing outbound digitized voice into at least one outbound IP packet, and a network interface for transmitting the outbound IP network onto a network which may involve a LAN, WAN or the Internet. The disclosed IP phone peripheral also includes an extractor coupled to the memory and controller for extracting inbound digitized voice within an incoming IP packet whose source address correlates to the destination IP address or addresses stored in the memory.

JVTOS - A Reference Model for a New Multimedia Service

Abstract: Multimedia Joint Viewing and Teleoperation is a new service for highspeed networks. It allows physically separated users to work in a collaborative fashion with documents and applications. It is however not a cooperative application but a system level service exporting the functionality of applications to many workstations. Keyword Codes: C.2.4; D.4.4; H.5.1
