| Figure 1. The three main scenarios for connecting devices with Windows 7 PCs
A second way exists to use a PC as a receiver. Some devices in the network include the ability to push content. In this case, the user browses content that is stored on the device itself by using the device user interface (UI), and then instructs a receiving PC to play the content. The PC acts as a media renderer when it is connected to the network.
In Scenario 3, a user discovers media servers and media renderers that are available in the network. The PC UI differentiates between content that exists in the local media library and content that exists in other media servers on the network. The user can search and browse the content and examine all the information that is available for each content item. The user can select content from any media server and push it to any media receiver. The PC acts as a media controller when the user selects content from a shared library on a media server; it acts as a push controller when the user selects content from the local media library.
