    摘要： Provided are a system and method for generating unified metadata for a plurality of distribution platforms. One or more processors in a broadcast provider system receive a linear media feed from a source device, and based on one or more inbound triggers associated with the received linear media feed, determines a plurality of segments of the received linear media feed. A unified metadata file comprising a universal schema of a plurality of category nodes and attributes for a plurality of distribution platforms is generated based on at least a programming schedule of the received linear media feed and an asset distribution interface (ADI) specification required by each of the plurality of distribution platforms. Further, a unified package is generated comprising the plurality of segments of the linear media feed as a broadcast media feed and the unified metadata file, and transmitted to the plurality of distribution platforms via a communication network.

    摘要： Methods and systems for identifying altered content are described herein. The system generates a fingerprint for an unverified content item and locates a plurality of content items that match the fingerprint. The system then compares corresponding frames between the unverified content item and each content item of the plurality of content items. The system identifies, based on the comparing, an altered frame in the unverified content item that does not match a corresponding frame in two or more of the plurality of content items. The system also determines that one or more frames of the unverified content item that follow the altered frame match corresponding frames in the two or more of the plurality of content items. The system then generates for display an indication that the unverified content item contains one or more altered frames.

    摘要： The unique watermark system comprising: identifying a presenter attendee, a first recipient attendee, and a second recipient attendee through a video conferencing session; detecting the presenter attendee sharing the visual content with the first recipient attendee and the second recipient attendee; selecting a first unique watermark and a second unique watermark from the plurality of unique watermarks and assigning them to a first recipient attendee and a second recipient attendee, respectively; inserting the first unique watermark into the visual content for the first recipient attendee and the second unique watermark into the visual content for the second recipient attendee; and transmitting the visual content with the first unique watermark to the first recipient attendee and the visual content with the second unique watermark to the second recipient attendee, wherein the method is performed by one or more special-purpose computing devices for hosting the video conferencing session.

    摘要： Methods, apparatus, systems and articles of manufacture to extend a time range supported by a watermark are disclosed. Example watermark encoding apparatus disclosed herein determine which one of a plurality of timestamp cycles is to be represented by a timestamp of a watermark. Disclosed example apparatus also swap at least two symbols of the watermark when the timestamp is to represent a second one of the timestamp cycles, but do not swap the at least two symbols of the watermark when the timestamp is to represent a first one of the timestamp cycles. Disclosed example apparatus further embed the watermark in a first piece of media.
