Abstract: A key server for controlling access of a client device to a subset of different quality copies of media content to be delivered over a network to the client device. In one embodiment, a key server receives a request for playback permission of media content by a client device, and applies a set of one or more business rules to determine which copies of the media content, if any, can be played by the client device, and allows access to a subset of the copies that can be played back by the client device and restricts access to the copies that are not part of the subset.

Abstract translation: 用于控制客户端设备访问要通过网络传递到客户端设备的媒体内容的不同质量副本的子集的密钥服务器。 在一个实施例中，密钥服务器接收客户端设备对媒体内容的播放许可的请求，并且应用一组一个或多个业务规则来确定媒体内容的哪些副本（如果有的话）可以被客户端设备播放 ，并允许访问可由客户端设备回放的副本的子集，并限制对不属于子集的副本的访问。
