Abstract
Content protection arrangements govern use of particular electronic content in a consumer electronic device. An exemplary arrangement authorizes use based not just on usage control data corresponding to the content, but also based on an attribute of the consumer electronic device. Thus, for example, playback of a song (or video) with particular usage control data may be authorized on a device that includes only analog output, but not be authorized on a device that is capable of outputting the content in an unencrypted digital format. A variety of other technologies and arrangements are also detailed.
