In video-on-demand (VOD) systems, as the size of the buffer allocated to user requests increases, initial latency and memory requirements increase. Hence, the buffer size must be minimized. The existing static buffer allocation scheme, however, determines ...

This dissertation presents a general design strategy for streaming media applications in best effort computing and networking environments. Our target application scenario is video streaming using commodity computers and the Internet. In this scenario, ...

Today's mobile devices enable the users to capture video clips with integrated digital cameras. However, capturing a video clip exactly as intended is often challenging -- in many cases, the possibility to edit the clip after capture would be useful. ...

This paper presents a high-level overview of Yahoo Research Berkeley's approach to multimedia research and the ideas motivating it. This approach is characterized primarily by a shift away from building subsystems that attempt to discover or understand ...

The IST Polymnia project is creating a fully automated system for personalised video generation, including content creation, selection and composition. This paper presents a linguistically motivated solution using context-free feature-augmented grammar ...

A QOS control is one of the most important factors in continuous media applications. The QOS levels of the applications should be maintained even if several continuous media applications are running concurrently. Also, the QOS levels ...

The required real-time and high-rate transfers for multimedia data severely limit the number of requests that can be serviced by Video-on-Demand (VOD) servers. Resource sharing techniques can be used to address this problem. We evaluate through extensive ...

This article describes a mechanism to acquire the semantics of video content from the activities of Web communities that use a bulletin-board system and weblog tools to discuss video scenes.

In this paper, a multiscale content-based video decomposition scheme is presented for efficient non-linear (nonsequential) organization of the video visual content. In particular, each video file is analyzed in a multiscale structure of different "content ...

Video inpainting uses spatial-temporal information to repair defects such as spikes and lines on aged films. We propose a series of new algorithms based on adjustable thresholds to repair different varieties of aged films. The main contribution is an ...

With the advent of virtual spaces, there has arisen a need to integrate physical worlds with virtual spaces. This integration can be achieved with real-time 3D imaging using multiple stereo cameras at several geographically distributed locations followed ...

In this paper, we present a method to predict per-frame decoding times of modern video decoder algorithms. By examining especially the MPEG-1, MPEG-2, and MPEG- 4 pt. 2 algorithms, we developed a generic model for these decoders, which also applies to ...

The standard frame sequence of an MPEG encoded video stream is suitable for normal playback. However, its inter-frame dependency makes it difficult to use it for interactive playback modes, such as play backward, jump or fast forward/backward. A scalable ...

Movie trailers, or previews, are an important method of advertising movies. They are extensively shown before movies in cinemas, as well as on television and increasingly, over the Internet. Making a trailer is a creative process, in which a number of ...
