Video stream preview
11503092 · 2022-11-15 · ·

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating a video stream preview. One of the methods includes receiving, from a user device, a request for a video stream preview. A payload of data is transmitted from a session system to the user device over a network. A first measure of network transmission quality is determined based on a result of transmitting the payload to the user device over the network from the session system. A second measure of network transmission quality is determined for data transmitted over the network from a session host to the session system. A video stream preview is generated from an example video stream obtained from the user device by degrading the quality of the example video stream according to the first measure of network transmission quality and the second measure of network transmission quality. The video stream preview is displayed on the user device.

Selective encryption of streaming data

An embodiment includes determining, in response to receiving data at a source node for transmission as streaming data on a network, whether a characteristic of the data indicates that an attribute of the data includes sensitive information. The embodiment also includes calculating, responsive to determining that the attribute includes sensitive information, an entropy value for the attribute. The embodiment also includes determining, responsive to the calculating of the entropy value, a likelihood that the attribute is encrypted by comparing the entropy value to a threshold value. The embodiment also includes generating a parameter value for a cryptographic parameter for the attribute.

Automatic context aware composing and synchronizing of video and audio transcript

A search query can be received. User parameters can be identified based on the search query. The search query can be refined to include the user parameters. A search result from a search for media content using the refined search query can be received. Based on at least one search result received from the search and based on the user parameters, an augmented media content can be generated. Playing of the augmented media content can be synchronized with a user's activity by controlling playing of the augmented media content while detecting the user's activity pace.

W3C media extensions for processing DASH and CMAF inband events along with media using process@append and process@play mode
11588870 · 2023-02-21 · ·

A method and apparatus for processing events in a media stream may be provided. The method may include obtaining media data; generating, from the media data, one or more event segments and one or more media segments; parsing a respective event from the one or more event segments to determine an event start time, event end time, and dispatch mode; appending the respective event from the one or more event segments to an event dispatch buffer based on a comparison of the event start time and a current playback position, and a determination that the respective event is not present in an already dispatched buffer; and dispatching the respective event based on the position associated with the respective event in the event dispatch buffer, the event start time, the event end time, and the current playback position.

Interactive real-time visualization system for large-scale streaming data

Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program, and a method for rendering interactive visualizations of high volume streaming data. Streaming data that describes a plurality of events is loaded in memory. The streaming data includes geospatial data that specifies a source location and a destination location for each event. Visual metaphors representing the events are rendered using a visualization mathematical model that defines, for each visual metaphor, a spatial position and opacity for each point along the visual metaphor throughout a sliding time window.

Systems and methods for rendering and pre-encoded load estimation based encoder hinting
11503313 · 2022-11-15 · ·

Systems and methods for hinting an encoder are disclosed in which a server monitors for information related to changes in frame rendering, calculates tolerance boundaries, rolling average frame time, and short-term trends in frame time, and uses those calculations to identify a frame time peak. The server then hints a codec (encoder) to modulate the quality settings of frame output in proportion to the size of the frame time peak. In certain embodiments, a renderer records one or more playthroughs in a game environment, sorts a plurality of frames from one or more playthroughs into a plurality of cells on a heatmap, and collects the list of sorted frames. A codec may then encode one or more frames from the list of sorted frames to calculate an average encoded frame size for each cell in the heatmap, and associate each average encoded frame size with a per-cell normalized encoder quality setting.

DELIVERING ENRICHMENT CONTENT BASED ON IDENTIFIER ASSOCIATIONS

First information associating a first unique master identifier with multiple different aliases is obtained from a first database accessible to an enrichment-content delivery system. The first unique master identifier is assigned to a first primary content item. Second information, which links the first unique master identifier to first enrichment content is obtained from a second database accessible to the enrichment-content delivery system. First playout information, which includes a first alias identifying a first media item scheduled for playout by a first media station is received from the first media station. A determination is made based on the first information and the second information, that the first alias is associated with the first unique master identifier assigned to the first primary content item. In response to that determination, the first enrichment content is transmitted to the first media station.

Publishing a plurality of disparate live media output stream manifests using live input streams and pre-encoded media assets

A media packaging and distribution system that allocates each of a plurality of first instructions from an instruction queue to a corresponding first worker based on an instruction type and a priority level. Each of the plurality of first workers reads a first manifest data, which is non-ingested metadata, of at least one of a plurality of live input streams or a second manifest data of a plurality of pre-encoded media assets from locations of corresponding input manifests. Further, a second instruction from a plurality of second instructions is allocated to a second worker. The second worker inserts a next manifest segment to a disparate live output stream manifest upon reading a manifest metadata ingested into a manifest metadata storage system. Accordingly, the plurality of disparate live media output stream manifests is generated for a plurality of channels based on the disparate live output stream manifest.
