A feature of current IPTV service is that the IPTV provider purchases the rights of contents from author of the content and serves those to consumer monopolistically. In this environment, IPTV is indistinguishable from the way of old broadcasting service. To shift away from this structure, it is necessary to guarantee the common user's participation like User Create Contents (UCC) and provide the...
This paper proposes an application oriented four layered quality of service (QoS) stack for wireless sensor networks (WSN), including a supporting system architecture for interacting with WSNs using the MPEG-21 multimedia framework in an medical application setting. The application of the WSNs is signal processing algorithms reporting elaborated observed sensor data to external users. The QoS model...
In the era of universal multimedia access (UMA), applications like video conferencing, surveillance and streaming are challenged by the multiplicity of devices. Since adaptation is the newly applied practice for digital video content customization, in this demo, we present a simple approach to adapt H.264 videos, in the compressed domain, for heterogeneous devices and mobile environments. Our approach...
The content technology need to conquer new forms with more intelligence, more flexibility and more features than those which are present on market standards. In this paper, the intelligent content model and format based on MPEG-21 is presented. The proposed format is an evolution of the MPEG-21/AXMEDIS model. The proposed model presents a set of new features among them: extended annotations, behavioral...
This paper proposes a system architecture for wireless sensor network (WSN) using the MPEG-21 multimedia framework in medical applications. It has been envisioned that future hospitals will have networks comprising WSNs for low rate medical sensors as well as other network nodes supporting high rate audiovisual content. The increasing collection and variety of media content (multimedia) in such a...
This paper addresses multimedia end user system design for content distribution over heterogeneous networks and terminals, with particular focus on end-to-end quality of service (QoS) control. A multimedia terminal comprising content-related metadata processor, usage environment characteristics provider, end user QoS monitor and H.264psilas extension scalable video coding (SVC) audio-visual player...
Scalable media contents, such as the new MPEG-4 scalable video codec enable to easily retrieve different qualities of the media content by simply disregarding certain media segments. The MPEG-21-based codec-agnostic adaptation approach supports this concept by introducing anXML-based bitstream syntax description (BSD) which describes the different segments of a media content. Based on this BSD, an...
This paper describes how a multimedia adaptation framework can automatically decide the sequence of operations to be executed in order to adapt an MPEG-21 Digital Item to the MPEG-21 description of the usage environment in which it will be consumed. The main innovation of this work with respect to previous multimedia adaptation decision models is that in the proposed approach decisions can be made...
A key objective of the ENTHRONE II Project is the ability to optimise the delivery of multimedia content to a wide group of heterogeneous users. One example of this is in the cooperative deployment of adaptation and caching functionality in the edge network. This hybrid approach makes it possible not only to store content locally, thus minimising the cost incurred through subsequent requests, but...
This paper addresses the end-to-end quality of service (QoS) guarantees and control for multimedia content delivery over heterogeneous networks, with a particular focus on end user terminal perspective. A multimedia terminal which embeds different probes to monitor network conditions and end user perceptual characteristics has been conceived and implemented. A series of QoS mapping between perception...
With the advent of the World Wide Web (WWW), large volumes of multimedia content are now available on-line in multiple formats. Furthermore, with the proliferation in the mass market of a diversity of multimedia-enabled end-user devices, consumers increasingly expect to be able to access any kind of content anywhere and at any time, regardless of the capabilities of their terminals and the networks...
The ENTHRONE II project (and its predecessor) heavily use open standards such as MPEG-21, MPEG-7, TV-Anytime, and H.264 as a basis for a full application stack system for Quality of Service (QoS)-enabled delivery for Digital Items. However, in order to reap the gains QoS offers, the project has had to develop a largely closed ecosystem of servers and end-user terminals for monitoring QoS along the...
