Abstract: Disclosed herein are methods and related systems to manage preview segments to be shared with non-subscriber presentation devices. An exemplary method maintains a preview segment generated from content available at an authorized subscriber device, and associates the segment with access parameters maintained at the server system. The parameters regulate and restrict access to the preview segment by non-subscriber presentation devices having restricted rights to directly view or access the source content. The server system receives an access request from a non-subscriber presentation device. The access request includes a preview identifier of the preview segment and a device identifier of the requesting device, a user identifier of a user of the requesting device, and/or a network address of the requesting device. The request is processed to determine access parameters for the preview segment applicable to the requesting device, and access is granted or denied based on the determined access parameters.
