Optimization method for monitoring transmission of video in 3G network

Abstract

The invention discloses an optimization method for monitoring transmission of a video in a 3G network, which comprises the following steps of: step one, waiting for a video connection request of a client by a video server side; step two, after receiving the connection request, sending TCP test data packets with different sizes; step three, after the client receives the TCP test data packets, sending a success badge to a customer; step four, after the server side receives the success badge sent from the client, determining the network delay and setting a transmission TCP packet with the optimal size according to a time stamp in the success badge; step five, according to the time delay, setting a data buffer area with the optimal size of the client; step six, setting the maximum size of an I frame, and setting quantization parameters of the I frame; step seven, directly and forcibly transmitting the I frame with the size by a compression core; and step eight, transmitting the I frame to the client which starts decoding after receiving the I frame. The method obviously reduces the waiting time of a user to see a first image.

Description

technical field [0001] The invention relates to a video transmission technology of a wireless network, in particular to a method for improving fast connection of video images under the condition of a 3G or other wireless network. Background technique [0002] With the commercialization and network optimization of domestic 3G networks, more and more video monitoring solutions are based on 3G, and 3G networks have also become an important carrier medium for digital video surveillance. Although the 3G network is convenient and covers a wide area, it still has many shortcomings compared with the traditional network, such as high delay, high bit error rate, unstable network bandwidth, and is less affected by the number of users, channel changes, user speed and signal carrier. big. These characteristics affect the user's final experience, thereby limiting the wide application of 3G video surveillance. [0003] In order to improve the above defects, the prior art generally procee...

Problems solved by technology

Although the 3G network is convenient and covers a wide area, it still has many shortcomings compared with the traditional network, such as high delay, high bit error rate, unstable network bandwidth, and is less affected by the number of users, channel changes, user speed and signal carrier. Big

In security monitoring, the interval of I frames is about 3-5 seconds, so customers will have a wait of at least 3-5 seconds, which gives customers a very bad experience "the network speed is very slow! "
