Embodiment Construction

[0021] The solutions of the present invention are described below in combination with specific embodiments.

[0022] A general monitoring system includes: monitoring management server (VM), monitoring front-end equipment (network camera IPC or encoder EC), media stream switching server (MS) and decoding end equipment, etc. To realize the transmission of large-flow video data on the WAN with link bundling, it is necessary for all monitoring devices in the monitoring system to work together to complete this task. The following combination image 3 To describe the specific operations performed by each monitoring device.

[0023] Step S1, the decoder judges whether there is packet loss caused by multi-link bundling, and if yes, notifies the monitoring and management server of the packet loss information; if not, the process ends.

[0024] The judgment of whether the packet is lost by the decoding end belongs to the prior art. In this embodiment, when packet loss occurs, it is n...

Abstract

The invention provides a code stream processing method for solving packet loss. The code stream processing method comprises the following steps that: a decoding end judges whether a packet loss condition is caused by multilink binding, and informs a monitoring management server of packet loss information if so, and the monitoring management server receives the packet loss condition information and notifies a code stream sending end and the decoding end to execute split and merged processing on an original code stream; the code stream sending end splits the original code stream into n code streams and sends the split code streams after determining that the original code stream needs to be subjected to split and merged processing; and the decoding end judges whether the received code steams are split n code steams and carries out merge decoding on the split n code streams if so. According to the code stream processing method, the video packet loss problem caused by link binding is solved. The code stream processing method is simple and flexible; and the size of the video code stream can be reduced without the cost of reducing the image resolution.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a code stream sending, processing and control processing method under the condition of link bundling. Background technique [0002] With the advancement of large-scale surveillance networks, the application scope of video surveillance is not limited to a park. Sometimes it is necessary to interconnect the surveillance of several branches and the headquarters through a wide area network, which makes more and more surveillance Video data traverses the wide area network. Such as figure 1 In the monitoring network shown, the monitoring data of site 1 and site 2 are transmitted to the monitoring center through the Internet. [0003] The network interconnection of large-scale surveillance sites makes the video surveillance data with large traffic flow must go through the network provided by the operator, but the network form of the operator is different. For example, the same 8M bandw...
