    Abstract: Systems and methods for remote access to personal television service are disclosed. A remote personal TV service center provides centralized program guide information. Users may access the personal TV service center through a digital video recorder which is connected to the personal TV service center via telephone modem or a network server. Users may access the personal TV service center through a remote computer terminal or a personal digital assistant which is connected to a computer network. A user selects program events and programs the digital video recorder using a graphical user interface installed in the digital video recorder in case of local programming, or using a similar GUI which is incorporated into the Web pages presented to remote users by a Web server in case of remote programming. The media stream stored in one digital video recorder may be transferred to another digital video recorder.

    Abstract: The present disclosure relates to systems and methods for classifying videos based on video content. For a given video file including a plurality of frames, a subset of frames is extracted for processing. Frames that are too dark, blurry, or otherwise poor classification candidates are discarded from the subset. Generally, material classification scores that describe type of material content likely included in each frame are calculated for the remaining frames in the subset. The material classification scores are used to generate material arrangement vectors that represent the spatial arrangement of material content in each frame. The material arrangement vectors are subsequently classified to generate a scene classification score vector for each frame. The scene classification results are averaged (or otherwise processed) across all frames in the subset to associate the video file with one or more predefined scene categories related to overall types of scene content of the video file.

    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.
