Abstract: Techniques for transmitting a digital content stream through a network between a plurality of content servers and a content player. Network performance information for the plurality of content servers is retrieved. Embodiments then determine a mapping of the plurality of content servers to a plurality of portions of a content buffer on the content player, based on the retrieved network performance information. A request is transmitted to each of the plurality of content servers to transmit digital content associated with the corresponding portion of the content buffer.

Abstract: In various embodiments, a clip application computes a set of appearance values for an appearance metric based on shot sequences associated with a media content item. Each appearance value in the set of appearance values indicates a prevalence of a first character in a different shot sequence associated with the media content item. The clip application then performs one or more clustering operations on the shot sequences based on the set of appearance values to generate a first shot cluster. Subsequently, the clip application generates a clip for the media content item based on the first shot cluster. The clip application transmits the clip to an endpoint device for display. Advantageously, relative to primarily manual approaches, the clip application can more efficiently and reliably generate clips for media content items.

Abstract: In various embodiments, a technique for reducing banding artifacts in decoded video data includes receiving a first set of reference samples, determining that the first set of reference samples meets a first criterion, selecting a first filter corresponding to the first criterion, applying the first filter to the first set of reference samples to generate a first set of filtered samples, performing at least one intra-prediction decoding operation on the first set of filtered samples to generate a first set of predicted samples, and generating a first portion of reconstructed video data based on the first set of predicted samples.

Abstract: In various embodiments a computer-implemented method for transmitting frames of digital content to a client device. The method includes transmitting a plurality of encoded frames of digital content to a client device for playback and determining that a frame loss rate associated with the plurality of encoded frames of digital content satisfies a frame loss condition, and in response to determining that the frame loss condition has been satisfied, determining a new interval for spacing apart reference frames when transmitting additional encoded frames of the digital content to the client device. The method further includes generating a new reference frame of digital content based on the new interval and transmitting the new reference frame of digital content to the client device for playback.

Abstract: The disclosed computer-implemented methods and systems can splice targeted content such as advertisements into a live stream of a real-time event. For example, the methods and systems discussed herein determine targeted content items for splicing into a live stream by generating a computing model of targeted content recommendations. In one or more examples, the computing model generates targeted content recommendations that are specific to a length of a targeted content break, the viewer of the live stream, and the player where the live stream is being viewed. The systems and methods discussed herein further determine the placement and duration of targeted content breaks based on signals and markers that are inserted into the live stream. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: In various embodiments, a model trainer application trains a machine learning model with improved identity robustness. The model trainer application first processes images of faces using a trained face recognition model to generate a proxy representation of an identity of the individual in each image. Representations of individuals with similar faces lie in the same neighborhoods within a proxy identity space. The model trainer application trains a machine learning model to perform a task relating to faces while considering the accuracy of each identity proxy neighborhood. The model trainer assigns different weights to each image sample in a neighborhood based on the number of samples with the same output class in that neighborhood. The assigned weights can then be used to compute a relatively unbiased identity loss function that is used to train the machine learning model to perform the task relating to faces while being robust to identity features.

Abstract: The disclosed computer-implemented methods and systems trigger actions by a client media player in response to determining that a live event has occurred during a live media broadcast. For example, the disclosed methods and systems determine that a live event has occurred during a live media broadcast and can generate instructions for various actions that the client media player should take in response to the live event. In one or more implementations, the disclosed methods and systems communicate these tailored instructions via the same dedicated communication channel that carries media content requests and responses. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: One embodiment of the present invention sets forth a technique for deblocking video frames. The technique includes determining a filter length associated with a boundary between a first block and a second block included in the same video frame. The technique also includes computing a parameter value that minimizes a sum of squares of second derivatives associated with samples from the first block and second block that are adjacent to the boundary. The technique further includes determining a plurality of filter values based on the parameter value and the filter length, and applying a filter having the filter length and the filter values to additional samples within the first and second blocks to generate two filtered blocks corresponding to the first and second blocks. The technique additionally comprises generating a second video frame that includes the two filtered blocks.
