Abstract

Methods and apparatus for delivering content to a user so as to optimize and enhance the “experience” of the content. In one embodiment, an optimization and monitoring entity (OME) is used which determines, evaluates, and provides notification and/or recommendation of alternative content delivery platforms which are available to a user. The OME receives requests for content forwarded from a content server containing information identifying requesting devices and/or subscriber accounts. The OME examines the capabilities of the registered devices, and identifies/recommends alternative devices based on e.g., video/audio quality, picture size, bandwidth availability, and/or any other additional capabilities of the client devices. A notification is then sent to the client devices indicating which of the user'"'"'s devices may receive the content alternatively, or in addition to, the requesting device. The notifications may be interactive, allowing the user to select one or more of the devices for delivery.
