1. Análise de desempenho no uso de pré-busca para distribuição de vídeo sobre redes P2P
Peer-to-Peer Video on Demand Systems have well stabilished its importance in recent years. Such consolidation is due to the high gains that may be archieved in terms savings in transmission bandwidth of the servers. In this work, we evaluate how this technology can enhance the gains for the transmission of continuous media over the Internet. To achieve this

2. Transmissões de vídeo ao vivo geradas por usuários: caracterização e análise
In the past few years, we have observed a huge revolution in terms of the way we create and distribute video on the Internet. With the popularization of digital cameras and with the increase of Internet access speeds, video content creation and distribution on the Internet has grown considerably. There are a number of recently created companies which offer t

3. IXnet - proposta de Internet alternativa para aplicações sensíveis a atraso. / IXnet - proposal of alternative Internet for applications sensitive to delay.
The Internet may does not meet all the demands required by applications sensitive to delay. Voice, video or even game applications demand low delay. The distance of hops between client and server, link traffic and the ramdomness of the package path, may cause delays. There is motivation and even implementation of alternative infra-structure to improve access

4. Métrica para análise da qualidade de vídeo transmitido em redes sem fio / Metrics to analyze the quality of videos transmitted through wireless networks
The goal of this work is to propose a metric to analyze the quality of videos transmitted through wireless networks. A wireless network is a degenerative means to transmit data given its huge instability, which affects transmitted videos. The present proposal adds a technical network parameter, known as jitter, to clients opinion. For these studies a video w

7. Transmissão de video em redes sem fio padrão IEEE 802.11b
The aim of this study is to investigate the video streaming transmission in wireless networks (WLAN) standard IEEE 802.11b, by using as clients portable devices notebooks and PDAs. Some experiments were made by the video transmission stored in a streaming server to the device and the performance has been checked. I would have been seen that when the networks

10. Uma arquitetura para gerenciamento de QoS baseado em políticas
The communication convergence (voice, video, data) is changing the way to plan, manage and maintain the network infrastructures. In this new concept of networking an important element to be managed is quality of service (QoS). The QoS management is a complex task and includes administrative concepts, such as: resource allocation, user levels assignment, diff

11. Metadata utilization in the video servers access management. / Utilização de metadados no gerenciamento de acesso a servidores de vídeo.
The experience with authoring multimedia material for educational purposes shows a major problem: how to provide an easy and efficient way to handle multimedia objects in a manner that non-expert users (namely school teachers) can be able to design and build their own presentations? The creation of this presentations involves factors like storage, delivery,

12. Sincronização de fluxos de dados em aplicações multimidia
In a near future, the computers will offer to users the possibility to manipulete continuous media through totally interacted systems. For these systems medias like, for example, audio and video are especially important and are called continuous media because of the closed relation with the time. In computing, the mechanism capable to maintain this relation
