METHOD AND SYSTEM FOR LIVE VIDEO STREAMING WITH INTEGRATED ENCODING AND TRANSMISSION SEMANTICS

This disclosure relates generally to method and system for live video streaming with integrated encoding and transmission semantics. The system receives a set of frames associated with a live video stream encoded to generate a set of data fragments using a reference encoder and a delta encoder. Transmitter unit of the live video streaming protocol transmits each packet of the set of full frames and the set of delta frames in sequence with a payload specific header based on a packet mode. Further, the receiver unit receives each packet of the full frames and each packet of the delta frames based on the packet mode to reconstruct an original sequence from the foreground pixels by estimating a total number of packets expected at each frame interval and loss incurred in each packet of the set of full frames and the set of delta frames.

A server includes a processor programmed to: acquire first metadata of a first media file recorded by a first mobile device; acquire second metadata of a second media file recorded by a second mobile device; determine that the first media file and the second medial file are likely recordings of the same event when a similarity exceeds a first threshold. The processor is further programmed to, when the first media file and the second medial file are likely recordings of the same event: determine, based on a comparison between the first media file and the second media file, which of the first media file and the second media file is a higher quality recording of the same event; and when the first media file is the higher quality recording, send a link to the first media file to the second mobile device.

A method including: ingesting a video segment and a set of video features of the video segment; estimating a part size distribution for the video segment based on the set of video features and a first rendition of the video segment; calculating a maximum expected part size based on a threshold percentile in the part size distribution; at a first time, transmitting, to an video player, a manifest file indicating a set of byterange-addressable parts of the video segment in the first rendition, each byterange addressed part characterized by the maximum expected part size; at a second time, receiving, a playback request for a first byterange-addressable part; transcoding the first byterange-addressable part; in response to the maximum expected part size exceeding a size of the first byterange-addressable part in the first rendition, appending padding data to the first byterange-addressable part; and transmitting the first byterange-addressable part to the AV player.

Verifying the rendering of video content at client devices using trusted platform modules
11700433 · 2023-07-11 · ·

Systems and methods for verifying the rendering of video content on information resources are provided herein. A server can transmit a video content element having a first bit stream corresponding to a predesignated frame to a client device. The client device can identify the first bit stream as corresponding to the predesignated frame. The client device can decode the first bit stream corresponding to the predesignated frame of the video content element to generate a second bit stream. The client device can transmit, to the server, a tracking message including the second bit stream. The server can compare the second bit stream included in the tracking message from the client device with a third bit stream maintained at a database. The server can determine that the video content element is rendered at the client device responsive to the second bit stream matching the third bit stream.

METHOD AND APPARATUS FOR IMPLEMENTING MULTI-PERSON VIDEO LIVE-STREAMING SERVICE, AND COMPUTER DEVICE
20230011255 · 2023-01-12 ·

The present application discloses techniques of implementing a multi-person video live streaming service. The techniques comprise obtaining a first video and a second video of a live streamer, and obtaining a third video of any other live streaming member than the live streamer in a live streaming group; stitching the first video, the second video, and the third video of the any other live streaming member, for obtaining a multi-person live video stream; and sending the multi-person live video stream to respective live streaming clients associated with members in the live streaming group for the members to watch. The present application can increase the modes of interaction of live streaming members, thereby improving the user experience.

Method, device, system, and storage medium for live broadcast detection and data processing
11700071 · 2023-07-11 · ·

The present disclosure provides methods, devices, systems, and storage mediums for live broadcast detection and data processing. In one exemplary embodiments, a user terminal device cooperates with a server and a camera device in a live broadcast system. The terminal device turns towards the camera device and outputs detection content within a detection time. It can be determined whether live broadcast content uploaded/captured by the camera device includes the detection content captured by the camera device within the detection time. If the detection content is found in the live broadcast content, it can be determined that unauthorized live broadcasting exists. Accordingly, corresponding measures can be taken to stop the unauthorized live broadcasting in a timely manner, which helps improve the security of user information.

Automated video cropping

The disclosed computer-implemented method may include receiving, as an input, segmented video scenes, where each video scene includes a specified length of video content. The method may further include scanning the video scenes to identify objects within the video scene and also determining a relative importance value for the identified objects. The relative importance value may include an indication of which objects are to be included in a cropped version of the video scene. The method may also include generating a video crop that is to be applied to the video scene such that the resulting cropped version of the video scene includes those identified objects that are to be included based on the relative importance value. The method may also include applying the generated video crop to the video scene to produce the cropped version of the video scene. Various other methods, systems, and computer-readable media are also disclosed.

Method and apparatus for processing video

A method and an apparatus for processing a video are provided technology. The method may include: separating a foreground image and a background image from a video frame in the target video stream, in response to acquiring a target video stream; adding a to-be-displayed content at a target display position in the background image to obtain a processed background image; and combining the foreground image and the processed background image to obtain a target video frame. The present disclosure may directly render the to-be-displayed content in the background, so that the content displayed in the background does not block a body in the foreground, such as person.

Content-modification system with transmission delay-based feature

In one aspect, a method includes determining a content-transmission delay between a content-distribution system and a content-presentation device. The method also includes using at least the determined content-transmission delay as a basis to select, from among a plurality of reference fingerprint data sets, a reference fingerprint data set that corresponds with the determined content-transmission delay. The method also includes transmitting to the content-presentation device, the selected reference fingerprint data set that corresponds with the determined content-transmission delay to facilitate the content-presentation device detecting a match between query fingerprint data representing content received by the content-presentation device and at least a portion of reference fingerprint data in the transmitted reference fingerprint data set.
