    Due to the large number of magnetic disks involved in a video server, the probability of disk failure is fairly high. Traditional parity-based and duplex-based (mirroring) approaches provide full data recovery, but do not guarantee full availability of the service in the presence of even a single disk failure. If a video server would like to provide non-disruptible services to a large number of vi... View full abstract»

    This paper addresses the problem of rapid browsing of a large set of World Wide Web documents, such as the results of a search engine query or a bookmark list. Traditional presentations of such lists are in the form of text, and require careful attention and often laborious efforts in order to discover relevant documents. We propose a visual representation of documents, called a caricature, which ... View full abstract»

    We describe an infrastructure for multiple perspective interactive video (MPI-Video) systems. An MPI-Video system assimilates data from multiple disparate sensors, allowing a user to interact with them in a meaningful way. At the heart of an MPI-Video system is an environment model (EM) that both assimilates data from multiple sensors and acts as an information server to clients. A collection of s...

    Unlike image data, video (animation) data contain the motion of objects. The spatiotemporal correlation of objects may represent certain semantic contents, which are not perceived by focusing only on the motion of an individual objects independently. We propose a content-based retrieval framework based on the spatiotemporal correlation of objects with a set of description factors of spatiotemporal... View full abstract»

  • Providing unrestricted VCR functions in multicast video-on-demand servers

    Cited by:  Papers (23)  |  Patents (7)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (136 KB)

    Full support for interactive VCR functions can be achieved only by dedicating a channel for each customer. Unfortunately, channel dedication should not be used in a multicast video-on-demand (VoD) system, because it degrades scalability; and hence economical viability, which is usually achieved by multicasting videos. The authors, therefore, propose and evaluate a fully-interactive, yet scalable, ... View full abstract»

    Publication Year: 1998, Page(s):368 - 371
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (184 KB)

    Distributed multimedia systems have stringent quality of service requirements which make them difficult to specify and implement. These include near-real-time constraints and synchronization requirements as well as complex user interaction patterns. Traditional approaches to the development of distributed multimedia applications have focused on specifying temporal constraints. Not much attention h... View full abstract»

    We consider a content-based adaptive clustering algorithm (CBAC) to extract a fixed pre-determined number of representative frames to summarize a given digital video. In our algorithm, shot boundary detection is not needed. The inter-frame changes are compared globally for the extraction of representative frames. Small units of the video are dynamically clustered into two clusters based on the amo... View full abstract»

    We propose a novel approach for effectively supporting multimedia packet flows in an Internet environment. The following are the key contributions of the paper: (a) we propose a new transport protocol called HPF that supports multiple interleaved reliable and unreliable data substreams; (b) we decouple the congestion control and reliability mechanisms that are integrated in TCP-this allows us to p...

    The paper describes trends in the development of multimedia processor architecture that may be predicted on the basis of the availability of an ASIC with 10s of millions of gates. Multimedia processing based upon multi granular parallelism for diverse media needs supercomputing power for multi threaded, process level execution.

    We present an optimal scheduling algorithm called Periodic Write-Read-Compute (PWRC) scheduling for video processing. PWRC scheduling exploits continuity and periodicity of the video data. Therefore, it is suitable for any type of periodic data over which data independent application is to run. The target architecture is a client-server based system having point-to-point communication between the ... View full abstract»

    The traditional boundaries between the computer, TV/film industries and telecommunications, are blurring. Therein lies the focus of MPEG-4: the convergence of common applications of the above mentioned three industries. MPEG-4 aims to satisfy the new requirements and expectations, by providing an audio visual coding standard allowing for interactivity, high compression and universal accessibility....

    Despite growing interest in multimedia data management, audio retrieval has received little attention. In part, this can be attributed to existing unstructured audio representations that do not easily lend themselves to content based retrieval and especially browsing. This paper aims to address this oversight. It begins by reviewing existing techniques and the specific problems posed by unstructur... View full abstract»

    In multimedia environments, digital artwork is usually exhibited on many types of media with different sizes and resolutions. For this reason, it is desirable that artists create works of art in a resolution independent way. We present an algorithm for resolution independent unrealistic imaging. To realize resolution independent imaging, characteristics of all brush strokes are coded and saved in ... View full abstract»

    The rapid growth of multimedia technology has resulted in an enormous amount of data that needs to be managed and indexed efficiently. To provide effective labeling for an image indexing system requires all objects in the image to be identified. To perform better and effective object identification, the process needs to be performed automatically and without priori knowledge of the image content. ... View full abstract»

    Execution of a collaboration application or a distributed game involves many individual multimedia applications that concurrently generate and consume audio and video streams. As the resource requirements of individual streams change and as streams/applications are started or terminated, the amount of available resources may change dynamically. Networked MultiMedia applications must be willing to ... View full abstract»

    We propose applying MIDI technology to coding of physiologic sounds such as heart sounds used in medical diagnosis for constructing medical audio databases. Furthermore, we extend our encoding algorithm in order to apply it to other types of sounds such as bird sounds and human singing. We overview our proposed encoding algorithms, which consist of a real time coding method and a high precision co... View full abstract»

    Various digital watermarking techniques have been proposed in recent years as the methods to protect the copyright of multimedia data. However, the rightful ownership problem has not been properly solved. Currently, there are two proposals to solve the ownership problem. Unfortunately, one proposal lacks a formal proof and the other can be easily defeated. We present watermarking methods which wil... View full abstract»

    The retrieval functionality of a multimedia database system is important to provide users with comfortable access to the stored data. Similarity retrieval (also called content-based retrieval) is a promising technique for multimedia retrieval. We have therefore been carrying out research on an image retrieval system that makes use of similarity retrieval. This kind of retrieval is based on nearest... View full abstract»

    Without proper care of the disk zoning issue, one may suffer a great loss in both storage and bandwidth utilization for supplying video streams. In this regard, the authors propose two schemes, free-π and fixed-π schemes, in a unified framework of rearranging the zone layout in a logical manner. The free-π scheme can optimally utilize resources, but needs a complicated timing control. Whe... View full abstract»
