Embodiment Construction

[0069] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0070] In the related art, images and coaxial data can only be transmitted between devices through a transmission medium such as a coaxial cable or twisted pair. If data other than image and coaxial data needs to be transmitted, additional wiring is required.

[0071] In order to avoid additional wiring and realize the transmission of target data, embodiments of the present application provide a data transmission method, a cam...

Abstract

Embodiments of the present application provide a data transmission method, a camera, and an electronic device. The method includes: acquiring an image to be transmitted, acquiring target data to be transmitted, determining a first position of the image to be transmitted in an effective image area of ​​the image frame, and determining a second position of the target data in a blanking area of ​​the image frame, The image to be sent and the target data are used as the data of the same image frame, the image to be sent is sent according to the first position by using the data transmission mode of the effective image area, and the target is transmitted according to the second position by using the data transmission mode of the blanking area data; wherein, the target data is data different from the image to be sent and the coaxial data, and the coaxial data is notification information interacted between the data receiving end and the data sending end. By applying the solution provided by the embodiment of the present application, the target data and the image to be sent can be sent to the electronic device in the same image frame without additional wiring, thereby saving the cost of the device.

Description

technical field [0001] The present application relates to the technical field of signal transmission, and in particular, to a data transmission method, a camera, and an electronic device. Background technique [0002] In a monitoring system, an image capture device (such as a camera) can send the captured image to an electronic device, and the electronic device can receive and store the image sent by the image capture device, and then display the surveillance video. At the same time as sending the image, the image acquisition device can also send the coaxial data to the electronic device. Coaxial data is notification information when devices interact. Image frames sent between devices can be as figure 1 As shown, the image frame includes an active image area and a blanking area. When sending an image frame, the image is usually used as the data in the effective image area, and the coaxial data is used as the data in the blanking area. [0003] In the related art, when tr...
