Abstract

A UPnP network provides a flexible technique for retrieving a resource content item from a media server using a parameterized uniform resource locator (URL). In operation, the media server sends a control point a parameterized URL in response to a consumer's browse or search request. The URL includes at least one parameter that specifies a characteristic attribute of the resource content item, which determines the manner in which the resource content item can be presented. For example, the parameter can describe a format type of the resource content item, a format resolution of the resource content item, and/or other property of the resource content item. The control point can modify a value associated with the parameter to produce a modified URL. This modified URL is submitted to the media server, whereupon the media server locates the resource content item and converts it to the characteristic state specified by the modified URL (if conversion is needed). The media server then provides the located (and potentially converted) resource content item to a rendering device for presentation thereat.
