Problems solved by technology

Although this method has already shaped the traffic, in actual applications, there are still situations where the traffic is prominent; therefore, it is the work that technicians need to carry out to further improve the existing traffic shaping technology

Embodiment Construction

[0031] In the case of not affecting the real-time performance of the video, the inventor considers that both the I frame and the P frame are designed according to the acceptable maximum frame transmission delay time to design the traffic transmission limit value of each frame. The scheme of the invention effectively reduces the traffic burst when the I frame and the P frame overlap between different video sources on the network node. For example, when multiple channels of live video are transmitted to the same destination for decoding, the network traffic will be smoother. The following will be described in detail through specific examples.

[0032]When the maximum sending delay time is set to a static value, the sending rate of the I frame is also a fixed value. In fact, the static maximum transmission delay time is often determined according to the preset current limit rate for I frames (such as 30Mbps mentioned in the background technology), that is, the maximum transmissi...

Abstract

The invention provides a method and device for video data flow shaping. The method is applied to an encoding device and comprises the step that when flow shaping is carried out on P-frame data, sending efficiency is set according to the smaller one of the maximum sending time delay time and inter-frame spacing time. According to the scheme, sudden flow burst generated when I frames and P frames of different video sources on network nodes are superposed is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method and device for video data traffic shaping. Background technique [0002] Because the original video data is relatively large, the video data needs to be encoded and compressed before it can be transmitted in the IP network, such as figure 1 shown. Common video compression codes include MJPEG, MPEG2, MPEG4, H264, etc. [0003] There are two common types of video compression coding methods: one is to use the spatial domain compression method, and the frames are relatively independent, and the data volume of each frame is relatively balanced, such as MJPEG; the other is to use the space domain and time domain. The combined compression method compresses video data by reducing the redundant information between frames, so there is generally a strong correlation between frames, such as MPEG2, MPEG4, H264, etc. [0004] For the MPEG and H264 video data compression me...
