Sažetak
This paper presents a model for an adaptive virtual reality (VR) service. The service adaptation, as described by the model, is performed by matching the parameters of – and possibly transcoding – the VR service in order to achieve the “best possible quality”, given the limitations of the terminal and access network, and taking into account individual user preferences. The matching process is based on two sets of parameters, called “profiles”: the VR service profile, which describes the VR service, and the client capabilities and preferences profile, which describes the client. Both profiles use Extensible Markup Language for notation, and are thus in line with the existing W3C standards. The model is independent of the particular VR service and network scenario, and it is suitable for heterogeneous environments such as the Internet and 3G wireless networks. A case study involving two prototype VR services demonstrates the applicability of the proposed approach.
