Since multimedia streaming has become very popular research topic in the recent years, this paper surveys the state of art techniques introduced for multimedia multicasting over mobile networks. In this paper, we give an overview of multimedia multicasting mechanisms in respect to cloud mobile communications, and we present some proposed solutions in perspective. We focus on the algorithms desi...

The factors limiting the efficient delivery and presentation of multimedia material in the cellular environment are, among others, the low bandwidth of the transmission channel(s) and the modest capabilities of truly mobile terminals. The ACTS1 project MObile Media and ENTertainment Services (MOMENTS) is leveraging the usage of state-of-the-art techniques for the handling of vector graphics and...

Multimedia multicast/broadcast transmissions provide simultaneous access to a common service to the heterogeneous user equipments (UEs) with different device and channel characteristics. One of the major challenges to the service providers is the exponential growth of energy-constrained UEs. In this context, the optimization of multimedia multicast/broadcast transmissions that consider the cons...

Perhaps the most dramatic Information Society development witnessed today is the wide availability of social networking capabilities for the users, orchestrated through the wide variety of virtual multimedia communication tools. Mobile and networked interactive multimedia applications are employed to promptly capture or create user-centered content that after being processed and enriched with t...

With recent advances in networking and workstation technology, a variety of distributed multimedia applications are now becoming feasible, e.g. multimedia desktop conferencing and distance learning. However, the deployment of such applications has so far been rather limited. In the authors’ opinion this limited deployment is largely explained by the immature state of distributed multimedia syst...

Distributed systems has been an area of intense activity over the past ten years. The subject is entering a stage of maturity with work now focussing on standards for Open Distributed Processing (ODP). However, it is important that standardisation is responsive to new demands on the technology. This is especially true with the emergence of high speed networks in general and multimedia computing...

M ultimedia is ubiquitous in our daily lives. In recent years, many multimedia applications and services have been developed and deployed, including mobile audio/ video streaming, mobile shopping, and remote video surveillance, letting people access rich multimedia content anytime, anywhere, and using different access networks and computing devices. It is anticipated that ubiquitous multimedia ...

In multimedia annotation, labeling a large amount of training data by human is both time-consuming and tedious. Therefore, to automate this process, a number of methods that leverage unlabeled training data have been proposed. Normally, a given multimedia sample is associated with multiple labels, which may have inherent correlations in real world. Classical multimedia annotation algorithms add...

Multimedia database management has been intensively studied recently due to the rapid growth of multimedia data and the demand of their access over the Internet. The new member of the MPEG (Moving Picture Expert Group) family, called the “Multimedia Content Description Interface” or MPEG-7 in short, will extend the limited capabilities of proprietary solutions in identifying multimedia contents...

Nanotechnology is providing the engineering community with a new set of tools to design and manufacture advanced devices which are able to generate, process and transmit multimedia content at the nanoscale. The wireless interconnection of pervasively deployed multimedia nano-devices with existing communication networks and ultimately the Internet defines a truly cyber physical system which is f...
