5results about How to "Improve playback efficiency" patented technology

This disclosure provides a method, apparatus, electronic device, and storage medium for displaying multimedia data, belonging to the field of multimedia technology. The method includes: acquiring a multimedia information stream; based on the multimedia information stream, when playing multimedia data in a playback interface, displaying a navigation component in the playback interface according to a display style corresponding to the feature information of the multimedia data, the navigation component being used for playback control. This method matches the display style of the navigation component to the feature information of the multimedia data, so that the navigation component is no longer a uniform, universal form. The presentation of the navigation component is adapted to the characteristics of the multimedia data and dynamically adjusted with the content. This not only ensures the basic implementation of playback control functions but also improves the coordination of the playback interface, balancing ease of operation and immersive viewing, presenting higher quality visual effects, ensuring the overall playback and interactive experience, and improving playback efficiency.

The invention relates to the field of Internet of Things and data visualization, in particular to a time-space synchronization fusion playback method and device for multi-source monitoring data, and the method comprises the steps: receiving a data packet uploaded by a mobile monitoring terminal; analyzing the data packet; associating the timestamp, the position stamp, the event stamp and the storage index of the media data under the same equipment identifier, and constructing a time-space fusion data association relationship; a playback request from the client is responded, a target data set is retrieved based on the time-space fusion data association relation according to the playback request, and the target data set comprises a continuous position track sequence in a target time period, all event marks and media data storage indexes associated with the event marks; and packaging the target data set into a fusion data packet, and issuing the fusion data packet to the client for the client to perform integrated playback. According to the method, the space-time relevance and the backtracking efficiency can be improved.

The utility model provides a slideway booster which comprises a boosting supporting plate and further comprises a pushing structure arranged at the bottom of the boosting supporting plate. And the boosting frame is arranged on the pushing structure. The air valve is opened, the air cylinder is pressurized to be in an expansion state, the air cylinder pushes the pushing frame to move, and the boosting frame pushes the sliding air cushion to slide into the sliding way to slide, so that sliding boosting can be well and automatically carried out, the labor force of workers is reduced, meanwhile, the working efficiency is improved, and the playing efficiency of tourists is well improved; a first fixing buckle and a second fixing buckle are separated, so that a third supporting block does not support two pushing blocks any more, then the pushing blocks are pinched towards the middle, a clamping block pushes a clamping groove, the second supporting block is not limited any more, the second supporting block is pulled out, and a rolling pulley is detached to be replaced. And the rolling pulleys are convenient to replace.

The invention relates to the technical field of video processing, and discloses a video playing method, device, electronic equipment and system, and the method comprises the steps: predicting a target video needing to be preloaded; when the target video meets a preset permission condition, executing a pre-decoding operation on the target video based on a pre-decoder to obtain pre-decoded data; the pre-decoding operation comprises a parallel pre-decoding operation and a PTS alignment operation; the pre-decoding data at least comprises first frame decoding data; storing the pre-decoded data in a memory cache region; on the basis of a state transition algorithm, decoding state information corresponding to the pre-decoding data is migrated to the main player; and after a playing instruction is detected, reading and playing the pre-decoded data from the memory cache region based on the main player according to the decoding state information. Visibly, the video can be pre-decoded before the video is played, so that the first frame can be rendered immediately when the video is played, the video playing efficiency is improved, and the experience of a user on a video playing function is improved.

The embodiments of the present specification provide a satellite data processing method and system, wherein the satellite data processing method comprises: receiving satellite data playback task information containing pre-application resource information, and generating a satellite data playback task based on the satellite data playback task information; at a target time associated with the satellite data playback task, calculating execution window information of the satellite data playback task according to the satellite data playback task information and parameter configuration information, and determining data file information according to the execution window information and the parameter configuration information; generating to-be-downloaded file information based on a data storage table associated with the satellite data playback task and the data file information, and executing the satellite data playback task based on the pre-application resource information, the execution window information, and the to-be-downloaded file information.
