Problems solved by technology

[0006] In the existing live process, the MS server is under great pressure as a forwarding device. When there are many forwarding channels, it will seriously affect the performance of the MS server and cause delays in data playback.
In the existing playback process, the DM server is under great pressure as a forwarding device. When there are many forwarding channels, it will seriously affect the performance of the DM server and cause delays in data playback.

Embodiment Construction

[0047] The present invention proposes a screen saver-based data transmission method, which is applied to a monitoring system including a VM server, a VC, and a data forwarding device. In a live process (that is, a VC checks live data), the data forwarding device is an MS server , that is, the MS server sends data (that is, live data) to the VC; in the playback process (that is, the VC checks the video data), the data forwarding device is a DM server, that is, the DM server sends data (that is, the video data) to the VC.

[0048] During the process of the data forwarding device sending data to the VC (that is, in the live process, the MS server has sent data to the VC; or, in the playback process, the DM server has sent data to the VC), if figure 2 As shown, the screen saver-based data transmission method provided by the present invention comprises the following steps:

[0049] In step 201, the VM server obtains the current screen saver status of the VC, which is the screen sa...

Abstract

The invention discloses a screen-saving based data transmission method and device, wherein the method comprises the following steps that: a VM (video management) server acquires the current screen-saving state of a VC (video client), wherein the screen-saving state refers to that the VC is in a screen-saving state or not in a screen-saving state; and when the current screen-saving state of the VC is that the VC is in a screen-saving state, the VM server notices a data forwarding device to stop transmitting data to the VC. In the invention, the forwarding pressures of DM (data management) servers and MS (media switching) servers can be reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method and device based on screen protection. Background technique [0002] With the development of video and audio coding and decoding technology and network storage technology, the video surveillance technology is formed by digitizing the image data of EC (Encoder, encoder), and transmitting and storing on the Internet network. The basic business functions of video surveillance technology include live broadcast, storage, on-demand broadcast, camera control, alarm processing, etc., and the digital video data of video surveillance can be used for real-time monitoring (realized through the live process), and can also be stored for subsequent playback ( through the playback process). [0003] The network diagram of the video surveillance system is as follows: figure 1 As shown, the video monitoring system at least includes: EC, which is a terminal for co...
