Media Content Distribution (MCD); 3D Gaming Graphics Delivery Overview

The present document provides an overview of delivery of 3D graphics of games that are running on a high-performance server to client devices that would otherwise not have the resources to run these games natively. The present document describes the use cases, high level requirements and different solution approaches, and identifies the main area(s) where standardization work would be needed. Exploring the nature and content of what is going to be exchanged between servers and clients constitutes the main topic of the present document The primary aim for this technology is to enable casual gaming scenarios, and it is not the primary aim to try to satisfy hardcore gamers, since we have to be realistic about what can be achieved with the current state of networking and server technology. Because of the nature of the content and in order to focus on feasible solutions, we may exclude certain type of network connections to be used, such as using "unreliable" or high-latency wireless connections such as 802.11b/g. We expect to have a broadband connection between the client and the server, without too many intermediate hops. In the present document we do not address deployment issues, such as integration into a Content on demand infrastructure (e.g. user registration, pricing, purchasing), or integration into a QoS framework (e.g. prioritization of gaming streams compared to other types of streams). Also, use cases and synchronization issues related to multi-player gaming, whereby different connection speeds/types could result in different response times, are out of scope of the present document.
