Adaptive Modulation and Coding (AMC), which is a technology used when channel condition changes, is adapted in Mobile Worldwide Interoperability for Microwave Access (WiMAX). Scalable Video Coding (SVC) is a video coding scheme used for different users with bandwidth level. SVC encodes a video into a number of layers. Users receive different number of encoded layers based on their channel condi...

This paper presents a seamless video service using web-cached multicast in WLAN. This system is composed of switching/multicast agent(SMA) and some access points(AP) with cache memory in wireless network. The proposed web-cached multicast technique for live-video can reduce the service delay, shortage of deficient network resources and the load of video server. Also, this system uses identifica...

Tema rada je izrada sistema za video konferencije. U tu svrhu implementirana Android aplikacija nalik aplikacijama slične namjene. Za potrebe razmjene audio-video stream-ova učesnika poziva implementiran server kao čvor na koji se klijenti kače i preko kojeg razmjena tih obavlja. Server razvijen u Java programskom jeziku, verzije 1.8, korišćenjem Spring razvojnog okruženja. skladištenje podatak...

The Internet has been a tremendous success in the past few years. New services offered by this data network are replacing or enhancing the traditional methods of communication. Multimedia applications such as distance learning, digital library, video conferencing are gaining more and more interest. However, despite increasing interest, these applications are not widely used. Such a situation ca...

A large scale, distributed video-on-demand (VOD) system allows geographically dispersed residential and business users to access video services, such as movies and other multimedia programs or documents on demand from video servers on a high speed network. In this paper we demonstrate through analysis and simulation the need for a hierarchical architecture for the video-on-demand distribution n...

Video on demand (VOD) system is an electronic video-rental service over a computer network. It provides users a service to browse and watch any video at any time with VCR (rewind, forward and pause) operations. One of the requirements for VOD system implementation is to have a VOD server that acts as an engine to deliver videos from the server’s disk to users. Designing VOD server, particularly...
