Abstract: One or more techniques and/or systems are provided for head end detection. A media receiver, such as a cable box, may be configured to receive cable television programming from a head end providing a channel lineup subscribed to by a user of the media receiver. Because an intermediate multimedia device, such as a computer or videogame system, may provide robust functionality for the cable television programming, it may be advantageous to identify and make the intermediate multimedia device aware of the head end. Accordingly, imagery of media channels may be captured from the media receiver. The imagery may be compared with fingerprints of content shows to identify a set of content provided by the head end. The set of content may be evaluated against channel head end lineup information to determine the head end (e.g., head ends that do not include content shows within the set of content are disqualified).

Abstract: Media purchase techniques are described. In an implementation, an indication is received that an item of media was successfully purchased through a single transaction that includes rights for access to the item of media in different forms that are optimized, respectively, for different classes of computing devices. Responsive to the receipt of the indication, the item of media is permitted to be streamed to at least one of the computing devices to enable output of the item of media for playback as the item of media is streamed and storage of the item of media to local storage of the computing device.
