  • Publication number: 20250150643
    Abstract: Camera equipment used for capturing a live event is expensive and may require professionals to operate the equipment. Such camera equipment is not accessible for capturing events and experiences by everyday users. Suppose media content is captured by lower-cost input devices such as mobile phones with a video camera. A production platform can use computer vision techniques to produce enhanced media content from media content captured by the lower-cost input devices. In one example, the production platform can aggregate and analyze the received media content to extract information and determine blind spots. The production platform can create or retrieve content based on the extracted information and insert the content in the blind spots. The production platform can deliver enhanced media content to an end user device, the enhanced media content may have the received media content and the inserted content.

  • Publication number: 20250142183
    Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for identifying scene breaks in media content. An example method comprises segmenting media content into a sequence of units by detecting unit boundaries. One or more feature encoders are applied to generate in an embedding space a multimedia representation of features of each unit in the sequence across different media modalities. A sequence classifier is applied to identify whether a unit boundary is a scene boundary based on the multimedia representation of units in the embedding space in at least a subset of the sequence of units.

  • Publication number: 20250118179
    Abstract: Disclosed herein are system, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for reducing and/or eliminating false positive alarm triggers. Detector devices positioned throughout an environment scan for known events that are likely indicative of an alarm condition. A source device that may generate such a sound or image may imprint a fingerprint on to the event that can be detectable by the detector devices but is imperceptible to humans. Additionally, the detector devices may use directionality and known locations of source devices to determine if a triggering event occurred at a known location of a source device. An alarm suppression decision may occur at the detector device and/or relevant information may be sent from the various detectors to a central console for a final alarm decision.

  • Publication number: 20250111764
    Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for reducing irrelevant alerts and/or network bandwidth usage from Internet of Things (IoT) cameras through the intelligent filtering out of video data. An example embodiment operates by receiving video data from an IoT camera. The embodiment further generates an ignore mask based on the video data, wherein the ignore mask specifies one or more regions in a video stream from the IoT camera that cannot trigger an alert. The embodiment then transmits the ignore mask to the IoT camera. The embodiment then receives the video stream from the IoT camera in response to transmitting the ignore mask to the IoT camera. The embodiment then determines that the video stream is associated with the alert. The embodiment may then transmit the alert to a user device in response to the determining.

  • Publication number: 20250106454
    Abstract: A method and system for controlling media-content presentation. An example method includes a computing system detecting that a media-player device has moved from a home location of the media-player device to a visited location and that the media-player device is connected with a media-presentation device at the visited location. Further, the example method includes, responsive to the detecting, the computing system causing the media-player device to output, for presentation by the media-presentation device at the visited location, media content selected by the computing system based on the media-player device having moved from the home location to the visited location. For instance, the computing system could cause the media-player device to output, for presentation by the media-presentation device, a message welcoming a user to the visited location and/or information about the visited location such as information about tourist attractions at the visited location for instance.

  • Publication number: 20250078511
    Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for sharing video streams in a camera system network. The video streams may be modified and/or masked to obscure private video stream features from being shared. An example embodiment operates by linking a first camera system to a first user device. The first camera system detects a second camera system in its field of view, wherein the second camera system is linked to a second user device. Upon exchanging requests to share video streams, the first and second user devices may view the video streams from both camera systems. The video streams may be modified to mask and/or obscure private property and/or known persons to preserve privacy despite sharing video streams. For example, the first camera system may modify and stream a masked video stream to the second user device.
