    When viewing multimedia presentations, a user can only be attending to a relatively small part of the video display at any one point in time. Accordingly, by shifting allocation of bandwidth from peripheral regions of the screen to regions-of-interest (RoI), which are measured or highly probable positions of user attention, attentive displays can be produced. This paper reports a perceptual compar... View full abstract»

    The rapid evolution in the hardware sector brought up various (mobile) end user devices like PDAs or cell phones on which online multimedia content can be consumed. Due to different capabilities of these devices as well as individual user preferences, the original multimedia resources have to be adapted in order to fit the specific devices' constraints and to meet the users' requirements. Given th... View full abstract»

    Advanced computing devices equipped with various wired and wireless network capabilities, built-in microphones and audio capture devices are becoming increasingly popular. At the same time, sophisticated signal processing algorithms for hands-free acoustic human-machine interfaces are being developed. Those algorithms are currently restricted to dedicated audio hardware, in part because they requi... View full abstract»

    Broadcasting protocols are used to reduce the bandwidth requirement of distributing popular videos in video-on-demand system. The scheme proposed in (Z. Zhang et al., 2004) claimed that it can reduce the client buffer requirement and the server network bandwidth of mirrored-pyramid broadcasting scheme (H.S. Ma et al., 2000) without increasing the client access latency. The idea in (Z. Zhang et al.... View full abstract»

    Channel modelling in a network path is of major importance in designing delay sensitive applications. It is often not possible for these applications to retransmit packets due to delay constraints and they must therefore be resilient to packet losses. In this paper, we first establish an association between traffic delays and the queue size at a network gateway. A novel method for predicting packe... View full abstract»

    The proposed ABA scheme uses the queue occupancy as a feedback to adaptively allocate the bandwidth for each queue of EF PHB. Because the allocated bandwidth converges to the corresponding input traffic, ABA remains the queue dynamics steadily. The feedback gain is used as an operational parameter to determine the steady state of each controlled queue. The characteristics of the steady class queue... View full abstract»

  • Adaptive MAP error concealment for dispersively packetized images

    In this paper we present an adaptive maximum a posteriori (MAP) error concealment algorithm for dispersively packetized wavelet-coded images. We model the subbands of a wavelet-coded image as Markov random fields, and use the characteristics of subband/wavelet samples to adapt the potential functions locally. The resulting MAP estimation gives PSNR advantages of up to 0.7 dB compared to the compet... View full abstract»

    In VOD systems, the limited disk I/O bandwidth and buffer space makes admission control very important. An online measurement based admission control algorithm on VBR video servers is proposed in this paper. By adjusting the length of scheduling period according to the residual system resources and deciding the variable range of period tolerance based on online measurement, the algorithm simplifie...

    In this paper a new spatial interpolation method is presented to deal with packet loss in transmission of compressed image data. The reconstruction process follows the steps as below. Firstly, the edge information of lost block is coarsely inferred using the intact pixels around the lost block. A NBP (nearest border prior) method is applied to the area with no edge information detected. To the are... View full abstract»

    Interactive digital TV is emerging as a potentially important medium to create opportunities for learning at home. To date, the offer has been mostly based on the contents available through broadcast, but this is expected to change in the near future. The increasing availability of high-quality bidirectional networks, together with the fact that IDTV users are abandoning their passive habits, envi... View full abstract»

    This paper describes a method of reengineering based on information technology engineering and object-oriented software engineering. Focused on the reusability issue, these two communities propose different technical solutions. The first, using XML technologies, describes the content in a structured formalism and the second recommends the implementation of the object paradigms of abstraction, refi... View full abstract»

    A lot of asynchronous systems have been developed to provide distance-learning solutions over the Internet. However, those environments are not able to give prompt feedback and they lack of interactivity. This research focuses on the provision of synchronous collaborative environments, focusing on the synchronous collaborative environment Platine designed and implemented in LAAS-CNRS with the help...

    In e-learning and distance teaching environments, course designers have to adapt their learning materials (resources and scenarios) to a preexisting social and technical context. Even if teaching experiences are acquired by taking into account learners and/or tutors feedback, e-learning systems often omit the reengineering purpose. In our framework, we consider that an e-learning system has to int... View full abstract»

    Interactive multimedia software capable of running on different devices, such as smartphones or digital television receivers, will be a consumer expectation in the near future. Supporting each device individually is too expensive. Therefore a common platform is needed. In this paper, a device independent platform for multimedia applications is presented. It is based on XML and Java and takes into ... View full abstract»
