Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The embodiment of the present invention provides a data transfer method, such as figure 1 shown, including:

[0028] 101: The source process generates and intercepts the source data, and obtains the transmission channel information of each target process;

[0029] The source process is the source that provides data, and the source process will generate source data. The source data can be sound, image, stream data, etc., and the sou...

Abstract

The embodiment of the invention discloses a method and device for data transmission. The method comprises the steps that source data are generated and captured through a originating process and transmission channel information of each target process is obtained; the target process corresponding to the source data and the transmission mode for sending the source data to each target process are determined according to the transmission channel information; the source data are sent to the target processes; an adopted sending method for sending the source data to each target process corresponds to the determined transmission mode of each target process. The source data are captured by the originating process, the transmission channel information of each target process is obtained, the target process corresponding to the source data and the transmission mode for sending the source data to each target process are determined, then sending of the source data is accomplished, the purpose that data of one originating process are obtained by the target processes is achieved, files do not need to be completely stored according to the scheme, the target processes do not need to obtain the latest data through the polling mode, and therefore the data transmission efficiency is high.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data transfer method and device. Background technique [0002] For inter-process data transfer, the general scheme that can be adopted can be as follows: [0003] The data provider creates a file on the hard disk, and then writes data into the file (the file may not be closed, but the buffer must be refreshed), and the data receiver opens the file in shared mode and reads the contents. [0004] This solution requires data to be provided to create files, and files need to be written continuously. The receiver of the data can only obtain the latest data by polling, resulting in low efficiency. The problem is particularly prominent when there are multiple application processes as data receivers. [0005] For example, after the camera captures the video, the encoding software needs to store the video as a file on the hard disk, and the video playback software needs to store al...
