An example apparatus includes a first query processor to obtain a first hash key, first qualifier data and first value data associated with the first hash key, the first value data including a second hash key and a third hash key; a candidate qualifier to use the first value data to prequalify the first hash key as a candidate for subsequent signature processing associated with a first site signature, the candidate qualifier to: determine prequalification of the first hash key is successful in response to a determination that the second hash key matches a second site signature preceding the first site signature in time and that the third hash key matches a third site signature following the first site signature in time; and determine the prequalification of the first hash key is unsuccessful in response to a determination that at least one of the second hash key fails to match the second site signature or the third hash key fails to match the third site signature.

Methods and systems described herein generate content that quickly cycles between different-colored frames at a rapid rate that may be imperceptible to human viewers. The human eye tends to blend nearby frames together, so that a human viewer will see a full color spectrum even though only a single color is displayed at any given time. The video display may repeatedly cycle between individual color frames, thus providing video content that appears normal to a human viewer. However, a video recording device may capture only some of the color frames. Therefore, the video recorded by video recording devices may include undesirable color flicker or other color artifacts, which may deter unauthorized copying.

A method includes receiving video segments from a transcoder of a media device. The video segments are associated with multimedia content. The method further includes detecting, during a delay associated with the multimedia content and using an artificial intelligence (AI) technique, a particular representation in at least one of the video segments. The method further includes generating metadata associated with the particular representation and sending the metadata to a multimedia player to enable the multimedia player to modify playback of the multimedia content based on the metadata.

Disclosed are examples for providing functions to receive a media file to be stored in a media repository. In the examples, a location in the media repository may be assigned to the media file. A media file address in a blockchain platform may be assigned to the media file. Metadata including the assigned location in the media repository and the assigned media file address in the blockchain platform may be added to the media file. A media file hash value may be generated by applying a hash function to the media file including the metadata. The media file hash value may be included in a message and uploaded to the assigned media file address in the blockchain platform as a transaction in the blockchain. An indication that the media file is uploaded to the media repository may be delivered to a subscriber device from which the media file was received.

A method and apparatus for publishing multimedia data, and a device and a medium are provided. The method includes: acquiring multimedia data to be published; in response to acquiring a multimedia synchronous publishing request, sending the multimedia synchronous publishing request to a second multimedia platform indicated by the multimedia synchronous publishing request, such that the second multimedia platform publishes synchronous multimedia data that is generated on the basis of the multimedia data to be published, wherein the synchronous multimedia data includes identification information of a first multimedia platform. Thus, a user can synchronously publish multimedia data at another multimedia platform by means of an original multimedia platform, and add an identifier of the original multimedia platform to the multimedia data that is published at the other multimedia platform, so as to enable a user at the other multimedia platform to be aware of the original multimedia platform.

Methods and apparatus to facilitate matching of names for same media content are disclosed. Example methods include analyzing first data associated with first media content and, when a program name/identifier and/or episode name/identifier is not identified in the first data, supplementing the data with second data to form third data and processing the third data with respect to fourth data associated with second media content and calculating a composite match score including a program match score and an episode match score based on processing the third data with respect to the fourth data. When the first media content is determined to match the second media content based on the processing of the third data with respect to the fourth data and a comparison of the composite match score to a threshold is satisfied, a normalized media name is generated for the first media content and the second media content.
