The invention discloses a method for extracting a video address based on a Webkit kernel under the HTML5 standard, and belongs to the technical field of network communications and multimedia information processing. The method mainly comprises the steps that a video website is analyzed through a Webkit kernel browser, a real address of a network video is extracted from a process of analyzing a webpage by the browser, the process of analyzing the webpage is controlled through an Injected Bundle interface, network requests which are irrelevant with the network video are shielded, and the video address is obtained from the simplified process. The corresponding program comprises three parts including a function library which is in communication with the Webkit analysis webpage process and is used for controlling the Webkit analysis webpage process, a top application oriented interface responsible for being in communication with an application program, and a corresponding data structure used for maintaining and controlling the website data and operation process of the video address extraction function library. Due to the fact that the process that the browser analyzes the video website is general, a user can analyze the video address of each video website through the function so as to obtain the real address of the video.

The invention provides an intelligent front-end multimedia information acquisition system used for accurately monitoring power station equipment. The system comprises a plurality of groups of data acquisition devices arranged in a production area I. The data acquisition devices are connected with equipment systems in the production area I. The data acquisition devices are further connected with anintelligent front-end data server arranged in a production area II through a first one-way safety isolation device. The intelligent front-end data server is connected with a second one-way safety isolation device. The second one-way safety isolation device is connected with a cloud server arranged in a management information large area through a private network. The system does not perform the simple lossy compression on acquired real-time data, wherein the sampling frequency and the data compression are dynamically adjusted according to actual needs. Meanwhile, data acquired in real time arestored in a structured database, while data not acquired in real time are stored in a non-structured database. Moreover, the data acquired by the system has the advantages of accuracy, integrity andconsistency. The system is safe in data transmission and high in efficiency. The same coding rule is adopted, and the data application is more efficient, more convenient and more purposeful.

The invention discloses a multimedia information processing method and system, a multimedia device and a terminal device. The method comprises the following steps: acquiring at least one kind of information of first information, second information and third information, wherein the first information is the characteristic information of the multimedia device, the second information is the characteristic information of the terminal device associated with the multimedia device, and the third information is the characteristic information of an environment where the multimedia device and/or the terminal device is located; judging whether the at least one kind of information meets a preset condition; and in the case that the at least one kind of information meets the preset condition, controlling the multimedia device to synchronize playing data to the terminal device. By adoption of the multimedia information processing method and system, when the multimedia device plays multimedia information, the audiovisual feel of audience can be better improved.

The invention provides a multimedia information transmission method and device and a terminal, and the method comprises the steps: obtaining multimedia data and description information in first equipment, wherein the description information is used for describing the environment of the first equipment during the recording of the multimedia data and the multimedia data; transmitting the multimediadata and the description information from the first device to the second device. The technical problem that description information cannot be transmitted when multimedia information is transmitted inthe prior art is solved.
