High-level signaling flow for Remoter Media Access on DLNA renderers
Source publication
The horizontally layered architecture of the IMS/NGN standards family enables the delivery of services independent of access network and requesting device. In this article, the authors propose a further separation of service control and delivery, allowing the requesting device – in particular a user's mobile phone – to invite other devices (we will...

... Sony Ericcson research group proposes a methodology of using barcode scanned by the mobile phone to provide connectivity information of DLNA network based on NGN (Next Generation Network) [71]. In [72] the architecture for the phone-based delivery of NGN services into residential environments introduces the possible solution of publishing connectivity and accessibility information about residential devices and services to a presence server, and this server can be accessed as a URL form which is transmitted to the mobile phone using new proximity technology (Barcode, NFC). [73] introduces a method to use a mobile phone to initiate the communication between DLNA Control Point and an Image Forming Apparatus. ...
Consumption of digital media is dramatically increased by the development of conventional connectivity technologies and the advent of home entertainment appliances. The evolution of networking technology, hardware development and advanced services leads to an increased sophistication of device manipulation and long learning curves for average users. DLNA standardizes the interoperablity between media devices over a framework. With the help of personal handheld devices and smart phones, a ubiquitous media network is formed at home or on the road. NFC is a radio technology bridging physical and digital world, which is now widely deployed in a varied number of application scenarios to ease Human-Computer Interaction. This master thesis proposes a system architecture based on the confluence of DLNA architecture and NFC technology to facilitate simple, intuitive and impromptu interaction with media devices. This NFC-enabled DLNA Communication system architecture defines a communication model which delivers the vision of NFC as the enabler of DLNA control and communication, a network model, a set of diverse device functional components, a set of dedicated devices and baseline principles of system architecture. Based on the generic system architecture, a research is explored on A/V and image media sharing, UI retrieval, media uploading/downloading and print document application fields. Six use cases are proposed, they share the properties and principles defined in the system architecture and additionally they maintain their own use case specific features and their proprietary NFC data formats. Among them two use cases are explained in more detail. One use case, A/V Handover, delivers a consistent "tap and exchange" scenario. The other use case, Control Handover, grants users an instantaneous access to the control UI. A prototype implementation between smart devices or home appliances are presented showcasing an instantaneous, rapid and spontaneous media sharing and management application. Following the design paradigm presented in this thesis, more use cases in specific application fields are easily to be implemented.
... Our demonstrator was developed in collaboration of Ericsson Research, University of Agder and RWTH Aachen. It is a simplification of our envisioned target architecture [7] and focuses on the separation of control signaling and media delivery to rendering devices. ...
... In line with our envisioned architecture, we are currently working on an enhanced version of the prototype, as outlined in [7]. This enhanced version utilizes IMS Presence Services [6] for remote service discovery and contains improvements addressing the aforementioned limitations. ...
In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the remote media player and access environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials. This paper describes a typical scenario and our prototype implementation.
