And the device and the serial server, and storing a plurality of authorization codes, a plurality of comparison codes, and address information of the stream server, wherein the authentication server is configured to receive the video capture device And the matching code, and comparing the identification code to one of the comparison codes, a push-stream connection information including one of the authorization codes and the address information Transmitting to the video capture device, so that the video capture device transmits the push connection information and the normal connection video to the streaming server, and the push flow connection is received by the streaming server After the information, the push flow authorization code included in the push flow connection information is parsed, and when the authentication server confirms that the push flow authorization code is correct, receiving the normal transmission by the video capture device Connect the video. The video streaming system of claim 6, wherein the authentication server is further communicatively coupled to the communication device, and the authentication server is further configured to receive one of the transmitted devices The identification code of the identification code, and compares the identification code with the ratio And when one of the codes is used, a pull connection information including one of the authorization codes and the address information is transmitted to the communication device, so that the communication device connects the communication device The line information and the play request are transmitted to the streaming server, and after the streaming server receives the pull connection information, the pull stream authorization code included in the pull connection information is parsed, and When it is confirmed with the authentication server that the pull stream authorization code is correct, the play request is received and the normal connection video is transmitted to the communication device by the pull stream signal through the third data communication protocol. The video streaming system of claim 6, wherein the video capturing device transitions from the connection interruption state to the subsequent normal connection state, and the authentication server receives the video capture And the authentication server will include one of the authorization codes and the address when the identification code transmitted by the device matches one of the comparison codes. The information back-up connection information is transmitted to the video capture device, so that the video capture device transmits the backup connection information and the disconnected connection video to the streaming server, and the streaming server is in the streaming server After receiving the replenishment connection information, the replenishment authorization code included in the replenishment connection information is parsed, and the video is received when the authentication server confirms that the replenishment authorization code is correct. Take the interrupted connection video transmitted by the device. The video streaming system of claim 8, wherein the identification code is a media access control address (Media Access) Control address; MAC address), the authentication server is an Authentication Authorization Accounting (AAA) server, and the push connection information, the pull connection information, and the backup connection information are one Uniform Resource Locator (URL).
