The present disclosure relates generally to techniques for dynamic secondary content insertion into streaming content. More specifically, the present disclosure relates to methods and systems for efficient transcoding and insertion of transcoded secondary content (e.g., advertisements or “ads”) into streamed primary content. Transcoded versions of content are associated and stored with a mezzanine version content identifier. Secondary content selection/insertion indications may use this identifier to select a secondary content independent of a particular transcoded version.

A data stream, such as a video stream, may comprise one or more event trigger messages indicating an upcoming event in the stream. The time (e.g., pre-roll time) between the event trigger message and its corresponding event may be modified, based on rules, to provide a network operator, service provider or downstream recipient more (or less) time to prepare for the event. This may be accomplished by moving the event trigger to an earlier (or later) location in the stream, and/or editing the event trigger to indicate the different pre-roll time.

Embodiments provided herein provide tiered manifest generation, tiered manifest distribution and/or both. This may result in efficient content distribution. Specifically, portions of a first manifest are used in a second manifest, enabling segment reuse. This may result in efficient encoding, storage, and provision of content in a content distribution workflow.

A non-transitory computer-readable medium includes computer readable instructions, that when executed by one or more processors, causes the one or more processors to perform operations including receiving a plurality of input images and receiving a guide image corresponding to at least one input image of the plurality of input images. The guide image includes additional colorization relative to the at least one input image. Additionally, the operations include generating a color mapping logic configured to adjust a color of the at least one input image to match the additional colorization of the guide image and outputting an indication of the color mapping logic.

A computer-implemented method may include receiving a streaming algorithm for testing and receiving historical network conditions of a player system. Simulating content streaming based on the historical network conditions and the streaming algorithm may include identifying a version of a fragment of content to be used in the simulated content streaming, simulating a download finish event of the fragment, and simulating a buffer level adjustment based on the simulated complete download of the fragment of the content. In response to performing the simulated content streaming, the computer-implemented method may report information associated with the simulated content streaming, thus enables measuring performance impact of player code change before deploying the updated player to production environment with neither conventional video nor audio playback.

A dynamic and selective tone mapping system that receives digital imagery content and adjusts the digital imagery content using defined perceptual point parameters that correspond to particular luminance points or regions of the digital imagery content. The defined perceptual point parameters include a first white reference value, wherein the tone mapping system adjusts the digital imagery content by compressing luminance values above the first white reference value at different compression rates to produce digital imagery content that is compatible with various media viewing devices with varying display brightness capabilities while preserving influence over the intended look of the displayed image resulting from the digital imagery content.

Systems and methods for detecting duplicate frames is provided. An automated duplicate frames detection service may extract one or more frames from content and determine a hamming distance between each of the extracted one or more frames and adjacent frames. In response to determining the hamming distance is less than a threshold hamming distance, the duplicate frames detection service may determine duplicate frames. In turn, the duplicate frames detection service may determine the duplicate frames are created without intent in response to determining the average distance between the one or more duplicate frames meets threshold criteria and provide an indication of the one or more duplicate frames without intent to a client device.

Techniques provided herein employ a device monitoring service to provide task to content consumption devices that are steaming digital media from the streaming infrastructure. The tasks, when implemented by the content consumption devices, may reveal differences in task performance between authorized devices, which have the authorization to access the digital media, and imposter devices, which exploit vulnerabilities in the streaming pipeline to access the digital media. In addition, the techniques provided herein may include a machine learning/artificial intelligence model that is trained to recognize authorized and imposter content consumption devices based on their task performance.

Systems and methods are provided herein for processing digital content. A registry includes a set of common registry identifiers used to classify metadata. Further, an interchange layer and registry classification service: receives metadata derived from digital content in a content file; and classifies the metadata, by associating the metadata with one of the common registry identifiers, based upon a classification from a set of classification rules that is associated with a metadata type of the metadata.
