7 results about "Video sharing" patented technology

The application relates to the technical field of vehicles, in particular to a vehicle-mounted video sharing method based on a PCIe bus, an automobile central platform, an electronic device and a computer readable storage medium. The method comprises the following steps: a plurality of system-level chips are connected in communication through a PCIe switch; in each system-level chip, an independent shared memory space is respectively allocated for each camera; when any system-level chip acquires video data, the video data is stored in the local shared memory space, and the video data is transmitted to a PCIe domain space through direct memory access after address mapping; other system-level chips acquire the video data from the PCIe domain space and store the video data in the local shared memory space; and in response to a reading request of the video data of an application program running on any system-level chip, the video data is read from the local shared memory space by the application program.

A method and system (100) for managing video sharing in a collaboration session is disclosed. A sharing function (112) obtains a synchronization timestamp of an audio frame of the collaboration session (B122), which is used to synchronize a shared video stream with the collaboration session. The sharing function (112) determines whether the shared video stream requires more, fewer, or the same number of video frames as the video file, based on the video frame rate difference between a desired frame rate and the source frame rate of the video file. The sharing function (112) iteratively retrieves video frames from the video file stored in a storage function (140) (B140). The sharing function (112) provides the shared video stream by sending one or more generated video frames to a video communication service (110) (B160). The video communication service (110) provides the shared video stream to two client devices (121) participating in the collaboration session (B174).

Embodiments of the present application relate to the technical field of terminals, and provide an audio and video sharing method, an electronic device, a storage medium, and a chip system. The method comprises: an electronic device may independently control each piece of audio and video information in interface play content, each piece of audio and video information being subjected to data transmission using an independent channel; and the electronic device may also perform stream mixing on each piece of audio and video data on the basis of settings of a user. In this way, the electronic device can separately manage and display one or more pieces of audio and video information on the basis of the selection of the user, thereby improving the viewing experience.

A method and system (100) for managing video sharing in a collaboration session is disclosed. A central server (130) obtains synchronization timestamps of audio frames associated with the collaboration session, which are used to synchronize the shared video stream with the collaboration session (B122). The central server (130) then determines whether more, fewer, or the same number of video frames are needed based on the video frame rate difference of the video files (B124). The central server (130) sets up a buffer for providing the shared video stream to the collaboration session (B130). This buffer is capable of buffering a limited number of video frames corresponding to time intervals of less than 1 second at most. The central server (130) iteratively obtains the video frames of the video file frame by frame (B140). For each video frame, the central server (130) generates (B150) zero, one, or more video frames based on the determination, and sets a timestamp for each of the generated one or more video frames. The generated one or more frames have a desired resolution, and each timestamp corresponds to a desired frame rate. Next, the central server (130) provides the shared video stream by inserting one or more generated video frames into a buffer (B160).

This application discloses a medical video sharing method, apparatus, device, storage medium, and product, relating to the field of medical technology. The medical video sharing method includes: receiving a video upload request initiated by a user interaction layer, wherein the video upload request includes an initial medical video; performing intelligent analysis on the initial medical video to obtain a target medical video labeled with analysis results, wherein the analysis results include medical entity information, surgical stage, and risk-related information; and saving the target medical video locally for users in the user interaction layer connected to the cloud server to browse the target medical video. This application eliminates the need for manual viewing and analysis, avoiding inefficiency and subjective bias.

This invention discloses a video content marking processing method, device, and computer-readable storage medium. The method includes: identifying and marking video objects in the video content during video playback, and obtaining selected operations and annotation operations for the marking; designating the video object corresponding to the selected operation and / or the annotation operation as a target object; and tracking and marking the target object in preset image frames before and after the selected operation and / or the annotation operation in the video content, based on the operation time of the selected operation and / or the annotation operation, until the target object leaves the video content. This provides a user-friendly video content marking processing solution, improving the effectiveness, purposefulness, and viewing convenience of video sharing, and enhancing the user experience of video sharing.
