Abstract: A media content pipeline architecture is described that enables media devices to efficiently receive, store, play, and stream media content. In general, a media content pipeline as described herein is configured to receive media content streams from one or more input sources, segment and store the media content streams into fixed-sized or variable-sized data buffers, encrypt the data stored in the buffers, and store the encrypted data in an in-memory buffer cache for further processing. The media content pipeline further may be configured to write the encrypted buffers stored in the in-memory buffer cache to a secondary storage device (e.g., a hard disk) in response to the occurrence of one or more defined operating conditions. The media content pipeline may enable a media device to efficiently receive and process media content data streams, write the media content data streams to storage, and stream the media content data to client devices.

Abstract: A method for generating and maintaining hierarchical tags with community-based ratings is provided. Tags for media streams are organized into a hierarchical format. Users may select tags from the hierarchical tag database that describes a particular multimedia content. If the user is unable to locate a desired tag, the user may submit a new tag. Upon submission of the new tag, a librarian approves the tag before storing and placing the tag in the hierarchical tag database. Users are also able to rate the quality of the association between the tag and the multimedia content. If a tag is rated low, the tag may be removed from the hierarchical tag database. If the tag is rated highly, display of the tag in a list of tags becomes more prominent.

Abstract: A method for displaying multimedia content is described. The method includes causing playing of multimedia content on a first device; responsive to a first user input, on a second device, comprising one of: playing, fast forwarding, rewinding, or pausing the playing of the multimedia content: causing an action comprising one of: playing, fast forwarding, rewinding, or pausing of the multimedia content on the second device at a start position that is based on the user input and a current position of the playing of the multimedia content on the first device.

Abstract: A media content management system that enables users to manage media content collections is disclosed. A media device is configured to receive requests to create media content collections for particular media content and, in response, to retrieve information related to the media content, and to generate one or more interfaces displaying information about created media content collections. In an embodiment, retrieving information related to a media content may include determining, for one or more episodes of the media content, whether the episode is available from various content sources, including both broadcast and broadband content sources. By enabling a media device to automatically retrieve and present information related to the availability of media content episodes across any number of different broadcast and broadband sources, users can more easily interact with and view information about particular media content of interest to the users.

Abstract: First media segments for a first media program are recorded. The first media program is scheduled to start at a first start time and end at a first end time, whereas a second media program is scheduled to start at a second start time and end at a second end time, the first end time being after the second start time. It is determined whether the first media program and the second media program are on a same channel. If so, one or more shared media segments, one of which is before all other shared media segments in the shared media segments and begins no later than the first time, are recorded. A first media program object is generated to represent a first recording of the first media program, and includes references to the first media segments and the shared media segments.

Abstract: Techniques for generating customized rating systems for use in a DVR are described. According to one technique, a user submits a rating system definition that comprises two or more different ratings of the user's choosing. The rating system definition is stored. The rating system definition defines a customized ratings system. That system's creator and other users may then associate various entities, such as channels, series, and episodes, with ratings from the customized rating system. DVRs may use these associations between entities and ratings for various purposes. For example, DVRs may use these associations to allow a user to search for entities that satisfy specified rating criteria. For another example, DVRs may use these associations to restricting which entities and information about those entities can be displayed or recorded when the DVR is in a restricted mode of operation. Customized rating systems may be modified by multiple users in collaboration.

Abstract: A system and method for navigating digital media assets including a navigation system configured to receive a search query in response to a user input and process the search query by applying the search query to a search index of digital media asset conventional and time-based metadata and determining search results of titles of and start points in time within digital media assets that satisfy the search query. The navigation system may then display the search results to the user through the user interface. The search results may be displayed in a hierarchical format, wherein the title of the digital media asset is displayed and upon selecting the title of the digital media asset, the start points in time within that digital media asset are displayed or played as a video to the user through the user interface.

Abstract: A system for remotely controlling client recording and storage behavior schedules the recording, storing, and deleting of multimedia content on a client system storage device. The viewer may request that certain content be captured. Capture requests also allow the service to determine content to be recorded by the client system in the same manner that a viewer requests that certain content are recorded but are more powerful than what a viewer can request. Recording requests for a capture request can preempt viewer requests or be entered at the same or lower priority as a viewer request. Capture requests can adjust all aspects of a recording request and affect the capture request itself. Client system operational functionality are also manipulated by the service using capture requests.
