摘要： Techniques for encrypting content in a content distribution network (150) are disclosed. The content distribution network (150) may comprise a number of national and local sites (100, 102), and a number of hubs (104) at each local sites. A content segment encrypting device (112) may be operative at a local site (102) to encrypt and cache segments of content. The segment encrypting device (112) may provide the segments to streaming devices (124, 126, 127) that encode content for delivery downstream to network or user devices.

摘要： Blu-ray ™ pairing with a video portal is described herein. The pairing capabilities are able to be stored on the Blu-ray ™ disc. Additionally, analytics are stored on the Blu-ray ™ disc which are able to determine which user took which action (e.g., pressed play, stop, skipped chapters, did not watch a video). By pairing the Blu-ray ™ with a video portal, a user is able to resume a video online where the user left off at on the disc or vice versa. Additionally, from the Blu-ray ™ disc or video portal, a user is able to take social networking actions such as "liking" on Facebook®, sending tweets, sharing content. The Blu-ray ™ disc also provides additional interactivity.
