whitepaper Technology for Providing Educational Video on Demand on Campus2008-11-21 Hewlett-Packard
  Much hope has been placed in the past on Educational Television for improving educational standards and distance education. However, in many countries the impact of this technology has been limited. Some of the reasons are discussed along with possible technical solutions. One solution that has been developed at HP Labs India is presented. This involves the use of satellite TV channels, using the MPEG format, as the distribution channel for educational content in digital form. Inexpensive TV equipment, including those that work with Direct To Home (DTH) TV transmissions are used to capture TV programs in digital form and store them on a server.

whitepaper Discrete LQ Rate Control for MPEG2 Video Streaming System2008-06-01 Academy Publisher
  This paper proposes a novel rate control system by applying the Discrete Linear Quadratic rate control method (DLQ) to transmissions of MPEG2 streams in IP networks. The paper gives out the detail deduction for disturbed-DLQ-regulator problem and the corresponding methods to implement the results into media streaming rate control. Study shows that DLQ is superior to conventional rate control schemes especially in client buffer utilization. Besides the basic DLQ method, the paper also investigates DLQ under heavy-traffic scenarios and provides improvements for this special case. The influences of delay, with respect to different mean values and variances, are discussed carefully.

whitepaper Bandwidth Consumption Control and Service Differentiation for Video Streaming2008-05-19 Electronics and Telecommunications Research Institute
  Multimedia streaming is resource demanding. It may starve other applications such as file transfer sharing the network, for example, in a smart home. To address the problem, a fuzzy logic control to bound the bandwidth consumption of multimedia streams is applied. This paper also differentiates the video quality for streams with different levels of importance. The transmission rate control and service differentiation schemes are implemented and evaluated in the department network where a number of different applications may coexist at the same time. Performance evaluation results show that the video streaming system can support the specified bit rate bound and differentiate the service to efficiently utilize the limited bandwidth.

whitepaper Load Balancing for Multimedia Streaming in Heterogeneous Peer-to-Peer Systems2008-05-14 Association for Computing Machinery
  Multimedia streaming of mostly user generated content is an ongoing trend, not only since the upcoming of Last.fm and YouTube. A distributed decentralized multimedia streaming architecture can spread the (traffic) costs to the user nodes, but requires providing for load balancing and consider the heterogeneity of the participating nodes. This paper propose a DHT-based information gathering and analyzing architecture which controls the streaming request assignment in the system and thoroughly evaluate it in comparison to a distributed stateless strategy. The impact of the key parameters is evaluated in the allocation function which considers the capabilities of the nodes and their contribution to the system.

whitepaper Adaptive Video Streaming for Mobile Clients2008-05-06 Association for Computing Machinery
  Digital video streaming has attracted large interest in research as well as in commercial areas in recent years. The evolution of digital video coding and broadband Internet access enables a large number of users to access high quality video streams with several devices varying from mobile phones to notebooks. However, digital video streaming still has high resource requirements concerning the transmission and decoding of the streams. Especially mobile devices often cannot comply with such resource demands. This paper briefly describes the multimedia gateway implementation which provides video adaptation to mobile clients by using multidimensional compressed domain transcoding mechanisms.

whitepaper Expand Service Offerings With Cisco Managed Media Solution V2.12008-04-01 Cisco Systems
  The Cisco Managed Media Solution 2.1 is a platform for delivering live and on-demand digital media, differentiating an operator's services from other content providers on the Internet. The Managed Media Solution allows High-Speed Data (HSD) operators to host content in the online video and addressable advertising markets from within their cable and wireline (DSL and FTTH) broadband access networks, while reducing expenses related to third-party hosting services and creating a new source of revenue and a clear return on investment. Operators can negate competitive threats, expand their advertising options, track content-consumption trends, and grow and retain their customer base - while delivering innovative media services and a compelling quality of experience that improves subscriber satisfaction.   
whitepaper Beyond the Browser: Monetization Strategies for Online Publishers in the Downloaded Media Age2008-02-27 Catalyst SF
  The potential for downloadable media to enhance publisher revenue is clear. The opportunity has become too large to ignore. But to truly realize the potential of this space, a publisher needs a purpose-built solution for downloadable media ad management and insertion. There are a number of firms that offer a solution but there is a need to fully evaluate these options to ensure that they offer a holistic solution for process work flow and ad serving tailored specifically to downloadable media.

whitepaper Microsoft Media Accelerator v1.02008-02-01 Microsoft
  Microsoft Media Accelerator enhances the online consumer experience by enabling providers to dynamically and temporarily increase Internet connection speed for high-speed content delivery and premium services. Installed alongside network equipment on a service provider's premise, Media Accelerator enables service providers and content providers to create activity-specific high-speed services so that any customer on that network can increase bandwidth speeds to download, upload, or stream digital content.   
whitepaper Scalability and Robustness of Virtual Multicast for Synchronous Multimedia Distribution2008-01-01 Masaryk University
  A simple UDP packet reflector for virtual multicast multimedia transfer is extended to form a distributed system of active elements that solves the scalability problem of otherwise centralistic approach. The robustness of such virtual multicast delivery system is also discussed and shown to be better than the native multicast can offer. The maximum latency, important for multimedia transfer and related to the number of hops through the network of active elements, can be kept bounded. Possible support for synchronized multi-stream transfer is also discussed.
