Problems solved by technology

In the existing video management software, if you want to save storage space or reduce network data transmission, you need to manually set the video resolution (primary stream or secondary stream) in the video management software, and cannot perform intelligent switching
During the recording process, the primary and secondary streams can only be manually switched, and cannot be intelligently and dynamically adjusted according to the environmental changes in the monitoring area

Embodiment 1

[0052] The present invention is mainly realized on the basis of the video monitoring system based on the TD-LTE network, generally, as figure 1 As shown, the video monitoring system based on TD-LTE network includes front-end SDI camera, TD-LTE video communication controller and video monitoring terminal connected in sequence.

[0053] The front-end SDI camera is usually responsible for collecting the original unencoded video data and sending it to the TD-LTE video communication controller.

[0054] As a communication terminal, the TD-LTE video communication controller usually transmits the video data collected by the front-end SDI camera to the video monitoring terminal based on the TD-LTE network. In the present invention, the TD-LTE video communication controller is also given another Function, that is, when people or objects move in the monitoring area, the TD-LTE video communication controller judges whether the alarm threshold is triggered through logical operation, trigg...

Embodiment 2

[0092] On the basis of Embodiment 1, the present invention also provides an intelligent switching system of primary and secondary streams based on TD-LTE network. The TD-LTE network-based intelligent switching system of primary and secondary code streams of the present invention may only include a TD-LTE video communication controller, or may include a front-end camera, a TD-LTE video communication controller and a video monitoring terminal at the same time. For the convenience of explanation, Figure 4 Combining the front-end camera, TD-LTE video communication controller and video monitoring terminal as an example, it shows a structural schematic diagram of an embodiment of an intelligent switching system for primary and secondary streams based on TD-LTE network of the present invention.

[0093] see Figure 4 In this embodiment, a TD-LTE video communication controller 301 of a primary and secondary code stream intelligent switching system based on a TD-LTE network includes:...

Abstract

The invention relates to an intelligent primary code stream and secondary code stream switching method and system based on a TD-LTE network. The method comprises the steps that a TD-LTE video communication controller receives video data collected by a front-end camera; the TD-LTE video communication controller transmits secondary code stream video data to a video monitoring end; the TD-LTE video communication controller obtains a regional difference coefficient by calculation according to the video data and judges whether the regional difference coefficient is greater than or equal to a threshold or not, and if the regional difference coefficient is greater than or equal to the threshold, alarming is triggered and an alarming signal is transmitted to the video monitoring end; the TD-LTE video communication controller receives a main code stream video data request sent by the video monitoring end; the TD-LTE video communication controller sends main code stream video data to the video monitoring end according to the main code stream video data request. The bandwidth resources and storage space can be effectively saved while the security and protection requirement of high-definition video monitoring is met, and operating cost of video monitoring is lowered greatly.

Description

technical field [0001] The present invention relates to the field of video surveillance, and more specifically, relates to a method and system for intelligently switching primary and secondary code streams based on a TD-LTE network. Background technique [0002] With the development of network video surveillance, network cameras with wireless transmission are favored by more and more people because of their convenient construction and high definition. [0003] The wireless video surveillance system based on TD-LTE technology can transmit high-definition video data streams, but it brings problems such as high-capacity storage and high traffic charges. In the existing video management software, if you want to save storage space or reduce network data transmission, you need to manually set the video resolution (primary stream or secondary stream) in the video management software, and intelligent switching cannot be performed. In the process of recording, the primary and second...
