As the Quality of Experience of video streaming can be greatly affected by parameters such as jitter, throughput, packet loss and delay, it is of great importance to assess the consequences low Quality of Service. Video artifacts are errors that can be displayed when multimedia streaming faces transmission difficulties. Blocking, ringing, motion compensation mismatch or false borders are some of the...
Software Defined networks (SDNs) paradigm tries to improve the network performance, facilitating the network management and the scalability basing on open-source software and adding a new entity called controller that manages the entire network. One of the goals of the controller is taking decisions in regards to routing instead of distributing it among the network nodes, as usual. However, this field...
In recordings of naturals environments there is often a predominant color due to the type environment such as a forest, a desert or ocean. Currently, there are a wide range of available video codecs that provide different compression results for different types of videos based on their predominant colors. Any way to save video flows bandwidth becomes a system to save or earn money. In this paper,...
In order to use intelligent video sensing systems, three main features should be satisfied. HD video transmission to provide enough video quality for image treatment, a wireless ad hoc network to intelligent locate and focus the issue to be sensed and enough available bandwidth to provide HD video quality. This paper presents a communication protocol designed and deployed to provide HD video transfers...
Wireless Local Area Networks (WLANs) are experiencing higher data rate and radius coverage, making possible high quality audio and video transmission. An IPTV system can be built in any home using the Wireless IEEE 802.11n standard because it provides enough data rate and range than the other IEEE 802.11 variants. IEEE 802.1a/b/g standards do not offer enough bandwidth to provide several ITPV channels...
The Internet Protocol (IP) architecture is very flexible and allows the transmission of any type of service over it. This is one of the main advantages when it is used for video transmission. IPTV service is currently one of the hot topics where industry and academia is providing their efforts and obtaining significant results. The next big step is to serve stereoscopic (3D) video and 3D-TV over IP...
Wireless Area Networks are commonly used for a great variety of applications. Actually, more and more people are using them as the access network technology for their home network or to access to Internet through a wireless router. In many cases, the access is performed in outdoors, not only in indoors. On the other hand, networks are experiencing a huge demand of services such as VoIP and IPTV that...
