20100274674 | MEDIA NAVIGATION SYSTEM - A media navigation system provides a user interface for navigating and interacting with streamed media objects, including video. The system may employ media markers representing time locations within a media file in addition to images or other representations derived from the media object. The system displays a tile layout representing a sequence of the media at an interval comprising a set of sub intervals corresponding to the tiles, and enables a user to click on the tiles to navigate to a next set of tiles which correspond to a different interval, and which replace the currently displayed tiles on the display. Navigation can include zooming in (smaller interval), zooming out (larger interval) and “panning” (preceding or succeeding interval) at arbitrary intervals. Individual tiles may also include visual indicators of relative importance or activity such as the number of comments associated with a sub interval. | 10-28-2010 |

20120005364 | SYSTEM AND METHOD FOR NETWORK AWARE ADAPTIVE STREAMING FOR NOMADIC ENDPOINTS - In a system for streaming data over a network, the type and rate of streaming are automatically varied based on available network bandwidth. Video media is transcoded into different bit rate encodings that are divided into segment files. Segments are sent from a network-aware adaptive streaming (NAAS) server and reassembled and presented to a media player at a client device. The system may download additional segment files ahead of time from multiple NAAS servers to increase throughput. A playback status (“bookmark”) may be maintained to keep track of what the user has viewed and to allow the user to continue playing from where the user left off. The user may continue watching from the bookmark point on the same device or on a different device. | 01-05-2012 |

20120144195 | METHOD AND SYSTEM FOR UNIFIED MOBILE CONTENT PROTECTION - Media content is delivered to a variety of mobile devices in a protected manner based on client-server architecture with a symmetric (private-key) encryption scheme. A media preparation server (MPS) encrypts media content and publishes and stores it on a content delivery server (CDS), such as a server in a content distribution network (CDN). Client devices can freely obtain the media content from the CDS and can also freely distribute the media content further. They cannot, however, play the content without first obtaining a decryption key and license. Access to decryption keys is via a centralized rights manager, providing a desired level of DRM control. | 06-07-2012 |
