Embodiment Construction

[0023] The multi-network adaptive selective switching transmission method of the present invention includes multi-network adaptive access strategy based on transmission delay, dynamic switching strategy of wireless heterogeneous network based on link quality and multi-channel adaptive selective transmission of wireless homogeneous network Strategy. After the transmission terminal is started, when the transmission terminal cannot establish a link with the monitoring center through static configuration, a multi-network adaptive access strategy based on transmission delay is used for link selection, registration and network access; when the transmission terminal When the terminal performs data transmission on the registered link, it uses the dynamic switching strategy of the wireless heterogeneous network based on the link quality to detect the quality status of other links in real time to decide whether to perform dynamic switching transmission.

Abstract

The invention relates to a multi-network self-adaption toggle selection transmission method and a wireless video transmission system. The method comprises the steps: when a link can not be established through static configuration, conducting selection, registration and network access to the link by adopting a transmission delay-based multi-network self-adaption access strategy; and in the process of data transmission, detecting the quality condition of other links by adopting the dynamic toggle strategy of a link quality-based wireless heterogeneous network so as to decide whether dynamic toggle transmission is conducted or not. The system comprises a transmission terminal and a monitoring center, the transmission terminal is connected with a 3G module, a Wi-Fi module and an Ethernet module, the transmission terminal is connected into an Internet through the 3G module or the Wi-Fi module, or into a campus network through the Wi-Fi module, so as to transmit the video data to the monitoring center. The method and the system are adopted for wireless video transmission, the transmission link can be favorably established quickly, and the transmission quality and the transmission speed of the video data are improved.

Description

technical field [0001] The invention relates to a multi-network adaptive selective switching transmission method and a wireless video transmission system using the multi-network adaptive selective switching transmission method. Background technique [0002] In the point-to-point wireless video transmission system, the front-end video transmission terminal is responsible for compressing the collected video stream, and then sending it to the designated local monitoring center on the Internet through the wireless communication module for decoding and playback, so as to achieve the purpose of monitoring. In the process of realizing the transmission of video data, various problems such as failure to establish a transmission link, poor link transmission quality, and low transmission speed often occur, which greatly reduce the effect of wireless video transmission. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior...
