Problems solved by technology

Some HD-SDI cameras provide a data transmission interface, but these additional data may be filtered out by HD-SDI switching equipment, because HD-SDI, which is commonly used in the broadcasting industry, is only used to transmit high-fidelity video and audio, Not defined for transferring data

Embodiment Construction

[0009] This method for HD-SDI cameras to transmit intelligent analysis data includes the following steps:

[0010] (a) Utilize the ISP chip or DSP chip of the camera to perform video analysis in real time;

[0011] (b) When the specified threshold is reached, an alarm will be triggered. At this time, the camera will send the intelligent analysis data or captured image screenshots to the back-end server through the audio transmission channel of the camera.

[0012] Intelligently analyzed data or captured image screenshots are sent to the back-end server through the audio transmission channel of the camera, so there is no need to add new data transmission interfaces, and the signal will not be lost.

[0013] Preferably, when there are 8 audio channels of the HD-SDI camera, the remaining 7 or 6 audio channels are used to transmit the intelligent analysis data, and the intelligent analysis data is packaged into audio data and embedded in the video data stream, through the same Sh...

Abstract

The invention discloses a method for transmitting intelligent analyzed data by the aid of an HD-SDI (high-definition serial digital interface) camera with no novel data transmission interface needed to be added and no signal loss. The method includes that: (1) an ISP (internet service provider) chip or a DSP (digital signal processor) chip of the camera is used for real-time video analysis; (2) the alarm is triggered when the assigned threshold value is reached and the intelligent analyzed data or the snap-shot image screenshots are sent to a backend server by the camera through a video transmission channel of the camera.

Description

technical field [0001] The invention belongs to the technical field of video surveillance equipment control, and in particular relates to a method for transmitting intelligent analysis data by an HD-SDI (High-definition serial digital interface) camera. Background technique [0002] With the wide application of HD-SDI high-definition digital cameras, there are more and more demands for adding intelligent analysis at the front end, but HD-SDI cameras are different from IP network cameras, and cannot follow the TCP / IP protocol to establish any number of data connection channels . Ordinary HD-SDI cameras have only one video interface and no dedicated data transmission interface. Some HD-SDI cameras provide a data transmission interface, but these additional data may be filtered out by HD-SDI switching equipment, because HD-SDI, which is commonly used in the broadcasting industry, is only used to transmit high-fidelity video and audio, Not defined for transferring data. Cont...
