Abstract: The present disclosure relates to methods, apparatuses and systems for displaying an alarm file and belongs to the field of communications. One of the method includes: through a persistent connection with a service end, receiving a data packet corresponding to the alarm file sent by the service end, wherein the service end releases a storage resource occupied by the alarm file after sending the alarm file; obtaining the alarm file by parsing the data packet corresponding to the alarm file; generating a uniform resource locator (URL) of the alarm file; displaying the alarm file based on the URL of the alarm file. The present disclosure can reduce wastes of the storage resource of the service end.

Abstract: A data processing method and apparatus, and an electronic device, a system and a storage medium are provided. The method is applicable to a main thread in a Web client and includes: obtaining audio and video data of a target video from a server decapsulating the obtained audio and video data to obtain first audio and video data; sending the first audio and video data to a target sub-thread in the Web client, so that the target sub-thread decodes the first audio and video data to obtain second audio and video data and sends the second audio and video data to the main thread; receiving the second audio and video data sent by the target sub-thread; and rendering video data in the second audio and video data by using a rendering module of a browser of the Web client, and taking the rendered video data and audio data in the second audio and video data as to-be-played data for the target video.

Abstract: Provided is a multi-language scheduling method. The method is applied to an embedded device. The method includes: receiving a language scheduling request from a terminal, where the language scheduling request includes a language pack identifier; when it is determined that there is not a language pack corresponding to the language pack identifier in a memory of the device, loading the language pack corresponding to the language pack identifier from an external storage medium of the device into the memory of the device; and then, obtaining the language pack corresponding to the language pack identifier from the memory of the device and returning the language pack to the terminal.
