MACHINE LEARNING OF ENCODING PARAMETERS FOR A NETWORK USING A VIDEO ENCODER

In various examples, machine learning of encoding parameter values for a network is performed using a video encoder. Feedback associated with streaming video encoded by a video encoder over a network may be applied to an MLM(s). Using such feedback, the MLM(s) may predict a value(s) of an encoding parameter(s). The video encoder may then use the value to encode subsequent video data for the streaming. By using the video encoder in training, the MLM(s) may learn based on actual encoded parameter values of the video encoder. The MLM(s) may be trained via reinforcement learning based on video encoded by the video encoder. A rewards metric(s) may be used to train the MLM(s) using data generated or applied to the physical network in which the MLM(s) is to be deployed and/or a simulation thereof. Penalty metric(s) (e.g., the quantity of dropped frames) may also be used to train the MLM(s).

METHOD AND SYSTEM FOR PROVIDING MEDIA CONTENT TO A CLIENT

A method for providing media content within a media distribution network. The method comprises transforming source media content into an interim format, thereby providing transformed content. Furthermore, the method comprises storing the transformed content on at least one core storage unit. In addition, the method comprises receiving a request for the source media content from a client. The method further comprises encoding the transformed content or intermediate coded content derived therefrom into encoded content suitable for transmission over a core network and/or an edge network, as well as sending the encoded content via the core network and/or the edge network to the client.

Constraint-modified selection of video encoding configurations

A video to be encoded to a plurality of different target encodings for bandwidth adaptive serving is received. The video is encoded into a plurality of different candidate encodings using different candidate encoding parameters. A quality metric is determined for each of the plurality of different candidate encodings. One or more different target quality metrics are selected for a first portion of the different target encodings based at least in part on one or more specified constraints for one or more target devices. One or more different target quality metrics are selected for a second portion of the different target encodings based at least in part on the determined quality metrics of the different candidate encodings. Based at least in part on the selected different target quality metrics for the first portion and the second portion, the plurality of different target encodings of the video is generated.

11582493 · 2023-02-14 · ·

The present invention relates to a method for dynamic image content replacement in a video stream comprising generating a set of key image data (K) comprising a sequence of at least two different key images (K1, K2), periodically displaying said set of key image data (K) on a physical display, generating at least a first original video stream (O1) of a scene which includes said physical display by recording said scene with a camera, wherein said at least one video stream (O1) comprises key video frames (FK1, FK2), captures synchronously with displaying each of said at least two different key images (K1, K2) of said set of key image data (K) on said physical display, generating a mask area (MA) corresponding to an active area of said physical display visible in said key video frames from differential images (AFK) obtained from consecutive key video frames (FK1, FK2), generating at least one alternative video stream (V) by inserting of alternative image content (I) into the mask area (MA) of an original video stream, and broadcasting at least said at least one alternative video stream.

Customized generation of highlight show with narrative component

Customized highlight shows for sporting events, entertainment events, and/or the like, having a narrative component, are generated and presented. The events can be sporting events, entertainment events, and/or the like. For example, in the context of sporting events, a determination is made as to what types of sports, teams, leagues, players, plays, and/or the like are of interest to the user. A customized highlight show is then generated and presented, containing those specific portions of the sporting events that are likely to be of interest, arranged in a manner that is likely to be entertaining and interesting to the user and that presents a cohesive narrative.

Content player performance detection

A method for monitoring and correcting playback performance for content player. The method includes detecting a content player request from a media player on a user device, the content player request corresponding to a content item request from a server, generating a playback identifier including data corresponding to the content item, detecting one or more playback events occurring during playback of the content by the content player, generating one or more playback packets including the playback identifier, a packet identifier, and the one or more playback events, and transmitting the one or more playback packets to a server.
