Adaptation of dynamically generated content

在这个领域中的大多数当前研究方向的焦点是基于服务器/单客户端关系，由此客户端向服务器请求媒体，提供其上下文元素，并且该媒体被处理并呈现给客户端。当这种关系不存在时，这种布置避免了某些考虑，例如在基于服务器/多客户端的系统（例如虚拟环境）中，其中每个客户端与其他客户端交互，并且服务器仅充当过滤和分发平台;或者对于客户端/客户端系统（例如视频会议），其中两个客户端直接彼此交互。在这两种情况下，将媒体存储在数据库或文件存储中的概念沿着媒体的某种标记描述不再可能-并且本质上，虽然可能存在存储在服务器上甚至在客户端上的某些元素，但媒体要么是动态生成的（例如视频会议），要么是作为混合的一部分（例如虚拟环境）。

The focus of most current research directions in this area is based on a server/single-client relationship, whereby a client makes a request to a server for media, provides its contextual elements, and that media is processed and presented to the client. This arrangement avoids certain considerations when this relationship is not present, for example in server/multiple-client based systems (e.g. virtual environments) whereby each client is interacting with other clients, and the server is acting merely as a filtering and distribution platform; or for a client/client system (e.g. video conferencing) where two clients are interacting with each other directly. In both cases the concept of storing media in a database or file store, along with some kind of tagged description for the media, is no longer possible - and in essence while there might be certain elements stored on the server or even at the client, the media is either being generated dynamically (e.g. video conferencing) or as part of a mix (e.g. a virtual environment).
