Systems and methods configured to detect and manage video transcoder latencies are described. A manifest is received and is used to request video segments included in a manifest playlist. A transcoder having an input and output is used to transcode video segments. A delta time for a first SCTE-35 marker between the transcoder input and the transcoder output is determined, where the delta time corresponds to a transcoder latency. A determination is made as to whether a corrective action needs to be taken with respect to the latency, and such corrective action is taken as needed. The corrective action may include a transcoder reset. The manifest may be a text file and may be in the form of an HLS or DASH manifest. Additionally, streaming latencies may be reduced by switching content distribution systems, increasing the number of edge systems distributing content to clients, and/or by increasing video cache memory.

Methods, systems, and media for selecting video formats for adaptive video streaming are provided. In some embodiments, the method comprises: receiving an indication of a video to be presented on a user device; identifying a group of quality metrics for each of a plurality of segments of the video, wherein each quality metric includes values for a particular segment and for a particular format of a group of available formats for the video; selecting a first format for a first segment of the video; causing the first segment of the video to be presented on the user device; identifying a quality of a network connection between the user device and a server that hosts the video; identifying a second format for a second segment of the video based on the quality of the network connection; determining whether a format of the video is to be changed from the first format to the second format based at least on the group of quality metrics for the second segment of the video; and, in response to determining that the format of the video is to be changed from the first format to the second format, causing the second segment having the second format to be presented by the user device.

A video player for playing a video stream that receives a master playlist identifying at least one variant playlist identifying a video file encoded as a series of video frames that when decoded provide the video stream. The video player based upon a configuration tag in the master play list selectively determining whether the video file is to be processed in a trusted execution environment. The trusted execution environment of the video player selectively includes at least one of (i) hack one, only hack one; (ii) output and link protection; (iii) hardware root of trust; and (iv) forensic watermarking, and decrypts and/or decodes the video stream in such an environment.

Techniques are disclosed for multiplexing a dynamic bit-rate video stream with an audio stream received by a client device in a manner that allows the resulting multiplexed stream to be played back without disruption, despite dynamic changes in the bit rate of the video stream that may occur. A content server may stream both a video stream and an audio stream to a client device for playback. The client device may multiplex the video and audio streams prior to them being presented to a playback engine for decoding and playback to a user.

Methods and apparatus for generating personalized menus and a media content interface are provided. In one example, different device specific media asset lists are generated at different user devices for the same user based on the media consumption history at each device. In another example, media asset listings are displayed for multicast and on-demand media assets determined to be of interest to the user. An on-demand media asset is listed at a time when no other multicast media assets are listed. In another example, media asset listings for successive episodes of a media series are displayed in sequential order in response to an input to view successive episodes of a media series. In another example, a text search for media content is performed in which the search priority of media provider results is decreased relative to the search priority of media asset results as additional characters are added to a search string.

An example device for processing extended reality (XR) data includes a processors configured to: parse entry point data of an XR scene to extract information about one or more required virtual objects for the XR scene, the required virtual objects including a number of dynamic virtual objects equal to or greater than one, each of the dynamic virtual objects including at least one dynamic media component for which media data is to be retrieved; initialize a number of streaming sessions equal to or greater than the number of dynamic virtual objects using the entry point data; configure quality of service (QoS) and charging information for the streaming sessions; retrieve media data for the dynamic virtual objects via the streaming sessions; and send the retrieved media data to a rendering unit to render the XR scene to include the retrieved media data at corresponding locations within the XR scene.

A system is provided for publishing a plurality of disparate live media output stream manifests using live input streams and pre-encoded media assets. A first instruction, comprising input manifest locations, is allocated to a first worker based on an instruction type and a priority level. At least one of a first manifest data or a second manifest data is read by the first worker from a corresponding input manifest location. A second instruction is allocated to a second worker. A next manifest segment is inserted to a disparate live output stream manifest by the second worker based on reading an ingested manifest metadata. Accordingly, a plurality of disparate live media output stream manifests is generated for each of a plurality of channels based on the disparate live output stream manifest.

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.

A system is provided for streaming media content in a vehicle. The system includes a personal media streaming appliance system configured to connect to a media delivery system and receive media content from the media delivery system at least via a cellular network. The personal media streaming appliance system includes one or more preset buttons for playing media content associated with the preset buttons. The media contents associated with the preset buttons are automatically determined to be personalized to the user of the system.

A method of playing video is provided. The method includes: obtaining a video loading instruction and sending a loading request to a cache server, wherein the loading request is configured to request loading data, and the loading data includes at least one segment of the video corresponding to the video loading instruction; receiving the loading data from the cache server; and playing the at least one segment according to the loading data.
