The received configuration indication may be verified to be authentic including processing the unique identifier, the received configuration indication and the received digital signature. The computing device may be operated or interoperated with in accordance with the received configuration indication. In one example, a service interoperates with the computing device. For example, the computing device may be a portable media player, and the service may provide media to the computing device based on a capacity indication of the configuration indication.

Abstract: Embodiments of a system that includes one or more integrated circuits are described. During operation, the system reduces power consumption by changing an intensity setting of a light source, which illuminates a display that is configured to display a video image, and scales brightness values for the video image based on a brightness metric associated with the video image. Then, the system calculates the error metric for the video image based on the scaled brightness values and the video image.

Abstract: An electronic device can play back media items using a random playback mode. To ensure that related media items are played back in a proper order (e.g., live music is played back in concert order), the electronic device can define metadata or other data coupling related media items in a predefined or preset sequence. For example, related media items can include metadata tags identifying the previous and next media items to play back in the sequence. As another example, the electronic device can store a listing of media items of a sequence and the order in which to play them back. When the electronic device reaches a media item that is part of a preset sequence during random playback, the electronic device can identify at least the subsequent media items in the sequence, and insert the subsequent media items in the playback queue. The electronic device can then play back the entire sequence before moving to the next media item in the playback queue.
