The main goal of VANET is providing safety and comfort for passengers. Live Video streaming over Vehicular Ad hoc Networks (VANET) is important for many applications, like online games, Collision warning, road sign alarms, emergency live video transmission and road-side video advertisement broadcasting. Vehicles have sufficient bandwidth, computation and storage capacity to support data intensi...

State of the art digital video compression produces bursty, variable bit rate video. The bursty nature of compressed video raises challenges in the design of video servers. In this paper, we first present a method for the efficient retrieval of bursty video data from the disk system to the memory of a digital video server. For a single video stream, the proposed retrieval schedule minimizes the...

In recent years there has been a strong interest in transmitting compressed Video over ATM. Previous work has dealt with transmitting MPEG over CBR and VBR services of ATM. The ABR service of ATM is expected to be much more cost eeective than CBR or VBR. There has been a limited amount of work done in transmitting video over ABR. However, there hasn't been much work done on running client/serve...

Video-on-Demand (VoD) has been an active area of research for the past few years in the multimedia research community. Significant research efforts have been directed towards reduction of network bandwidth requirements, improvement of server utilization, and minimization of start-up latency. Server load and network bandwidth are the major performance issues in streaming video over the Internet....

We consider the design and potential benefits of peerassisted video-on-demand, in which participating peers assist the server in delivering VoD content. The assistance is done in such a way that it provides the same user quality experience as pure clientserver distribution. We focus on the single-video approach, whereby a peer only redistributes a video that it is currently watching. We first d...

We present an open-source web-based multimodal dialog framework, “Multimodal HALEF”, that integrates video conferencing and telephony abilities into the existing HALEF cloud-based dialog framework via the FreeSWITCH video telephony server. Due to its distributed and cloud-based architecture, Multimodal HALEF allows researchers to collect video and speech data from participants interacting with ...

This work describes the prototype of the DFG Collaborative Research Center 1053 on ’Multi Mechanism Adaptation for the Future Internet’ (MAKI) on switching between network mechanisms during runtime. The replacement of whole network mechanisms of a system is called a transition. Transitions are necessary when environmental conditions change significantly. In this demonstration we show the advant...

Large-scale Video-on-Demand (VoD) systems with high storage and high bandwidth requirements need a substantial amount of resources to store, distribute and transport all of the content and deliver it to the clients. We define an extension to the VoD equipment allocation problem as determining the number and model of VoD servers to install at each potential replica location and the origin such t...

This paper presents the literature review on distributed video management cloud platform using Hadoop. Due to complexities of big video data management, such as immense processing of large amount of video data to do a video summary, it is challenging to effectively and efficiently store and process these video data in a user friendly way. Based on the parallel processing and flexible storage ca...

This paper reports on our progress in developing an advanced video-on-demand (VOD) testbed, which will accommodate various multimedia research and applications such as Electronic News on Demand, Columbia’s Video Course Network, and Digital Libraries. Two different prototypes have been completed. The first generation of the testbed was based on a constant-bit-rate (CBR) video server utilizing Et...
