Abstract: Systems and methods for a video scan are provided. The scan may be dynamically interactive and a function of characteristics of the programs in the scan (e.g., commercial breaks or the end of a program approaching) The scan may simultaneously display multiple scan windows for a plurality of programs, for example in a scan wizard. The scan wizard allows the user to simultaneously view a scan window and an information panel, select criteria for the scan from a criteria panel, and control the scan using a scan control panel. The scan may allow the user to record a program displayed in the scan without interrupting the scan (e.g., by using an additional tuner). The scan may display, within the scan interface, trick-play functions for appropriate scanned programs (e.g., recorded, cached and on-demand programs). The user may select and perform trick-play functions for a scanned program without exiting the scan mode.

Abstract: Systems and methods for rewinding a video to a point before the video was first viewed. Video transmitted by a media source is cached by a remote server. Upon a trick-play request for the video, the server generates a rewind stream that includes the video that was transmitted by the media source before the user started to view the video. Upon receiving the rewind stream, the user's equipment may cache the rewind stream in a rewind buffer and rewind or play from the rewind buffer. The server may also generate and transmit a forward stream of the video that the media source has not yet transmitted. The user's equipment may cache the forward stream in a forward buffer. To perform trick-play operations with the video, the user's equipment may migrate the playback of the video to the rewind and forward buffers and rewind or fast-forward the video from the buffers.

Abstract: The invention manages resources and resolve conflicts when locally recording multimedia assets from a variety of sources in multimedia delivery systems. Local and system resources such as storage, tuners, and bandwidth are considered when alternative sources for assets are available (e.g., VOD). Rather than record assets locally, if equivalent assets are available via alternative sources, the recordings are deferred and a pointer to the equivalent asset is stored in lieu of the asset itself. When a user selects a multimedia asset for playback, an “on demand” or alternative source session is started for the asset associated with the pointer. Before the expiration date of the alternative source equivalent of the multimedia asset, it may be downloaded and recorded locally. The system may automatically determine based on various factors, such as transmission bandwidth, latency, and DRM, whether to store assets or pointers.

Abstract: Systems and methods for viewing media content are provided. A set of media content with at least one feedback application is created. In response to the set creation and activation, media content may be tuned and launched automatically while other programming is restricted. User input associated with feedback applications may be received and media content rewards may be awarded.

Abstract: Systems and methods for skipping advertisements while playing back a video that includes at least one advertisement are provided. When a user reaches the advertisement, the user may select to skip the advertisement. In response to the skip instruction, the interactive media guidance application may identify and display substitute media instead of the advertisement. The substitute media may be an image, a video frame, a video clip, a graphic, or any other suitable media. The interactive media guidance application may identify the substitute media to display from advertisement data associated with the skipped advertisement. The substitute media may be displayed for a designated length of time (e.g., less than the time it would take to fast forward past the advertisement). Once the time for displaying the substitute media has lapsed, the interactive media guidance application may resume playback of the video following the end of the advertisement.

Abstract: Systems and methods for simultaneously recording multiple programs using a single tuner. A content source generates a digital transport multiplex having multiple programs. An interactive television application tunes to the digital transport multiplex using a tuner and simultaneously records the programs. The content source may create a personalized digital transport multiplex having programs requested from one or more interactive television applications.

Abstract: Systems and methods are provided for improving the market appeal and/or usability of information manipulation and/or display devices (IMDDs).

Abstract: On-demand systems and methods are provided to manage locally-stored on-demand content. A user's equipment controls the deletion of and/or access to on-demand content from a local storage device based on constraining criteria that may include rental conditions, dynamic factors, and keys.

Abstract: Systems and methods for providing more flexible multi-user media content access using index points is provided. A plurality of custom index points are maintained in a multi-user or multi-room media system. After receiving a request to view an asset, a listing of the index points associated with the requested asset is presented to the user. Each index point may be associated with a current viewing location within the asset. After receiving a selection of an index point, the asset is accessed at the viewing position referenced by the index point, and the index point is updated based on the user's progress through the asset. Users may assign custom names and descriptions to the index points and be presented with cached video around the index point in order to more easily identify the relevance of the index point.

Abstract: Systems and methods for displaying substitute media while fast forwarding past advertisements are provided. When a user reaches the advertisement, the interactive media guidance application may receive an instruction to fast forward the advertisement. In response to the fast forward instruction, the interactive media guidance application may identify and display substitute media instead of the advertisement. The substitute media may be an image, a video frame/clip, a graphic, an animated graphic, or any other suitable media. The substitute media may be distributed in the advertisement using any suitable method. For example, the substitute media may be incorporated in the video frames of the advertisement (e.g., overlaid in the video frames of the advertisement), added as hidden video frames distributed in the advertisement, or any other suitable approach.

Abstract: Systems and methods for providing custom video mosaic pages are provided. The custom pages may be locally-generated, remotely-generated, or partially locally-generated and partially remotely-generated. The custom pages may include local content, such as content recorded to a digital video recorder (DVR), overlaid on a multi-video composite feed. A local compositing system may render the mosaic pages and dynamically customize the pages based on user profile data, user preferences, and active user monitoring.

Abstract: Systems and methods are provided for deleting viewed portions of recorded programs. In one embodiment, a media guidance application may provide a list of recorded programs, where each recorded program in the list includes an indication of an amount of time that the recorded program has been viewed. From the list, a user may flag the viewed portions of one or more recorded programs for deletion. In some embodiments, the media guidance application may provide a delete prompt in response to a user command to pause or stop playback of a recorded program. The delete prompt may provide the user who is viewing the recorded program with the ability to choose to delete the portion of the program viewed thus far. For example, the delete prompt may prompt the user to delete a portion of the recorded program that starts at the beginning of the program and ends at substantially the position that the user stopped or paused the recorded program.

Abstract: A restoration path planner minimizes cost while meeting restoration-time constraints of a network by reducing the worst-case number of cross-connections that must be performed in a network in the event of a single element failure. The planner involves optimization that identifies primary and restoration path plans for demands within the network such that the worst-case number of cross-connections at any node within the network is minimal and/or bounded. Embodiments further constrain the cost of the path plan. In one embodiment, restoration time is bounded and cost is relaxed until a solution is found. In another embodiment, the restoration time bound is relaxed to a limit while path plans and their costs are stored. These plans can later be chosen amongst for the desired balance of cost and restoration time. At least one approach to minimization of network cost involves maximizing sharing within restoration path plans.

Abstract: Systems and methods for managing the storage of recordings in a recording device in which the recordings were requested by several users are provided. Each user may be assigned a storage space limit defining the amount of storage space each user is entitled to use. In some embodiments, the storage space limit may be flexibly increased to take advantage of extra space available from other users. The system may intelligently borrow space from other users to limit the risk that a requested recording is canceled due to unavailable storage resources. In some embodiments, the system may jointly allocate a recording to several users who commonly requested a recording. The system may also set aside space in the recording device that is saved exclusively for a particular user. In some embodiments, the recording device may allocate the storage resources based on the usage of the recordings.

Abstract: Multiple-level phase amplitude (M-PAM) clock and data recovery circuitry uses information from multiple phase detectors to generate one or more data sampling clocks that are optimized for each of the data slicers. One possible 4-PAM implementation includes 3 data slicers, 3 edge slicers, 3 phase detectors, and a single VCO. The phase detector outputs are combined (e.g., via weighted voting, weighted average, minimum error, and/or minimum variance) to determine an optimized phase estimate for the clock used to sample the data at all three data slicers. Another 4-PAM implementation similarly includes 3 data slicers, 3 edge slicers, 3 phase detectors, and a single VCO. The mid-amplitude edge slicer and phase detector are used in combination with the VCO to generate a central phase while a multiple-tap delay line provides N phase variants before and after the central phase.

Abstract: A method and associated apparatus for indicating the voice of each talker from a plurality of talkers to be heard by a listener. The method uses a signal that is transmitted over a telecommunications system. The method includes projecting the voice from each one of the plurality of talkers to the listener. A talker indicator is provided proximate to the listener. Talker identification information is generated in the talker indicator that can be used to indicate the identity of each talker who is speaking at any given time to the listener. A device is coupled to the talker indicator that can transmit the voice signal from each talker to the listener. In different aspects, the talker identification information can include such varied indicators as audio, video, or an announcement combined with a temporally compressed voice signal. In another aspect, an emotographic figure is displayed to the listener that each represent a distinct talker.
