whitepaper Cisco - Implementing QoS Solutions for H.323 Video Conferencing Over IP2006-05-04 05:25:04 Cisco Systems
  H.323 is the standard with global acceptance for multimedia conferences in an IP network. Many IP video conference applications use the H.323 suite of protocols. The International Telecommunications Union (ITU) H.323 defines an international standard for multimedia over IP. ITU approved the first version of the H.323 standard in 1996. The current version is 4. Many applications now commonly deploy LAN-based H.323 video systems. An example application is Microsoft NetMeeting, which utilizes H.323 for video conference and shared collaboration. This paper discusses tools to implement Quality of Service (QoS) for H.323 video conferences over an enterprise WAN with relatively low-speed links.   
whitepaper Mobile Content Delivery2006-07-04 02:51:15 BEA Systems
  The Mobile Content Delivery Solution (MCDS) breaks away from the siloed architectures of today and utilizes a horizontal Service Oriented Architecture approach. This approach leverages the individual components in the MCDS solution to create, deploy, and deliver a wide spectrum of applications and content. MCDS provides the carrier with revenue generating opportunity through the ability to cross sell and up sell content via personalization, bundles, and campaigns. MCDS allows operators to quickly and easily define and implement targeted campaigns allowing the promotion of content and content bundles such as games, ring-tones or music to users most likely to purchase them. MCDS also provides a user experience that is simplified and tailored for their device.   
whitepaper A Turbo-Coded Multiple-Description System for Multiple Antennas2006-02-01 Institute of Electrical and Electronics Engineers
  This paper proposes a joint source-channel coding scheme for wireless communication systems with multiple transmit and receive antennas. The source coder is realized by a multiple description encoder that generates multiple bit streams. Each description is then separately turbo coded and transmitted using multiple antennas. For the receiver, the paper describes a suitable iterative joint source-channel decoding technique that exploits the correlations between the descriptions and presents several examples that illustrate the performance of the proposed system, and compares it with other approaches.

whitepaper ARGOS: Automatically Extracting Repeating Objects From Multimedia Streams2006-02-01 Institute of Electrical and Electronics Engineers
  Many media streams consist of distinct objects that repeat. For example, broadcast television and radio signals contain advertisements, call sign jingles, songs, and even whole programs that repeat. The problem the paper addresses is to explicitly identify the underlying structure in repetitive streams and de-construct them into their component objects. The algorithm exploits dimension reduction techniques on the audio portion of a multimedia stream to make search and buffering feasible. The architecture assumes no a priori knowledge of the streams, and does not require that the Repeating Objects (ROs) be known. This paper outlines the algorithms; enumerate several applications and present results from real broadcast streams.

whitepaper BEA WebLogic Communications Platform and IP Multimedia Subsystem (IMS): Next-Generation Converged Services2006-07-04 03:16:42 BEA Systems
  As widespread deployment of the IP Multimedia Subsystem (IMS) begins to solve the fundamental challenge of connectivity across network domains and lays the groundwork for value added services, application and service infrastructure will face new challenges. The convergence of legacy telecommunications networks with all-IP infrastructure offering data, voice and multimedia services requires a flexible and robust, execution environment for network applications. This white paper describes the market need for IMS, how it works, how it can be used, and how the BEA WebLogic Communications Platform suite helps CSPs deliver new IMS network services. The strength of IMS is realized when existing network assets are leveraged into new services.   
whitepaper Enabling Wireless and Pervasive Services2006-05-10 01:00:27 Telenor
  Future wireless and pervasive services require advanced value networks and extensive cooperation between operator and service provider. This paper has looked into the implications of pervasive computing through a scenario called CyberCity. In CyberCity every citizen can offer situated services to every other citizen. The paper discusses how an operator can support this scenario by providing a platform of enabling services that can be used by all service providers in exchange for revenue for the operator and identifies a number of these enablers that are necessary for implementing CyberCity.

whitepaper HD Broadcasting: The Looming Content Crunch2006-05-03 11:27:53 ADIC
  As broadcasters are shifting from analog to digital operations, they are also reallocating resources to accommodate growing consumer demand for high definition content. IT operations at every stage of the industry's value chain now strain to support environments that must accommodate larger files, increased bandwidth requirements, and accelerated time-to-market expectations. The need to squeeze every bit of value out of all intellectual property within a company means that stored data must be managed with the greatest efficiency possible. This paper examines the storage requirements imposed by the shift to manage high definition content, and suggests sensible guidelines that will help managers define their strategies as they shift to digital storage for their high definition content.   
whitepaper IP Multimedia Services Charging2006-01-01 Hewlett-Packard (HP)
  To keep subscribers engaged and traffic flowing across the network, operators are adopting a customer centric approach, including addressing customer needs with value-added services, the bundling of converged voice, data services, seamlessly merging an individual's private and professional usage, and merging family member accounts while adding new features like mobility and personalization. The drive for converged services requires that mobile, fixed, voice, video and data network architectures be consistent. In response, network service providers are embracing IP Multimedia Subsystem (IMS) technology. This paper explains what IMS is, why it offers a more effective means of addressing these challenges, and demonstrates how the HP Convergent Charging solution successfully enables the evolution to IMS.

whitepaper Evolution of Media Servers for IMS/NGN Services2006-11-30 01:00:16 Alcatel
  Media Servers (MS) will play a key role in future IMS/NGN networks. More advanced services require more and more complete interaction with the user. Consequently, the Media Servers or Media Resource Platforms that are deployed in today's networks need to be enhanced. IMS, first designed for mobile networks, is now being promoted as a converged solution for both fixed and mobile networks. IMS-compliant Media Servers as defined by IMS standards, aim to provide a decoupled and flexible architecture, thanks to an optional split of the Media Resource Function Control (MRFC) and the Media Resource Function Processor (MRFP). This paper focuses on the evolution of Media Servers.   
whitepaper Using Fixed/Mobile Convergence to Competitive Advantage2006-11-30 01:00:17 Alcatel
  New, disruptive VoIP business models are springing up rapidly and are often said to herald the demise of established voice providers, both fixed and mobile. With very significant revenues at stake, there is clearly mileage in established players fighting for this territory that they already own. Fixed Mobile Convergence (FMC) offers established voice players a good chance of seeing off the disruptive newcomers. Yet this will not be achieved with "More of the same only cheaper", but by exploiting selected key user demand: building a simple customer experience across a wide range of communication services; integrating services so customers are shielded from complexity and services are more useful; and leveraging brand strengths like integrity and security across all communication channels.
