With the advent of generic remote visualization solutions, accessing distant graphics resources from the desktop is no longer restricted to specially tailored applications. However, current solutions still suffer from poor interactivity due to limited network bandwidth and high latency. In this paper we present several improvements to our remote visualization system in order to overcome these d...

In recent times the integration of video, audio and data in telecommunication devices has revolutionized communication world. It has proven to be useful to almost every industry: the corporate world, entertainment industry, multimedia, education and even at home. The major problems associated with these applications are the high data rates, high bandwidth and large memory required for storage a...

Automatic data compression in the web proxy server is an important mechanism that can potentially reduce network bandwidth consumption and web access latency significantly. However, unlike traditional data compression, web protocols and data have unique characteristics that make compression challenging. These include data block streaming, wide range of data object sizes and types, and real-time...

Video is the key element for the growing trends in the mobile industry. Reducing the amount of video data that can be transmitted over a connection is strongly recommended to meet out the bandwidth requirements. Video compression is a coding technique which reduces the actual number of bits than the original data and hence the bandwidth is increased. In this work, a detailed study is done on vi...

Managing the bandwidth requirements of a team of robots operating cooperatively is an ubiquitous and commonly overlooked problem, despite being a crucial issue in the successful deployment of robotic teams. As the team’s size grows, its bandwidth requirements can easily rise to unsustainable levels. On the other hand, general-purpose compression techniques are commonly used to transmit data thr...

Digitalized video and audio system has become the trend of the progress in multimedia, because it provides great performance in quality and feasibility of processing. However, as the huge amount of information is needed while the bandwidth is limitted, data compression plays an important role in the system. Say, for a 176 144 monochromic sequence with 10 frames/sec frame rate, the bandwidth is ...

The problem of local bandwidth of a typical electrocardiogram (ECG) is the first issue to consider when developing a structure-dependent algorithm for ECG signals compression. Our aim at this stage is to find out the bandwidth variability that means the bandwidth of every ECG structure taking into account the possible morphological changes, noise and so forth. The research done answered a very ...

The transport of images across communication paths is an expensive process. The limitation in allocated bandwidth leads to slower communication. To exchange the rate of transmission in the limited bandwidth the Image data must be compressed before transmission. JPEG2000 image compression system follows huffman coding for image compression. Embedded zero tree wavelet (EZW) coding exploits the mu...
