Multiple video forwarding method based on port numbers and IP addresses

Abstract

The invention discloses a multi-video forwarding method based on port numbers and IP addresses, and belongs to the video transmission field. The multi-video forwarding method based on port numbers and internet protocol (IP) addresses comprises a video server, a forwarding server and a terminal, wherein the video server sends multi-channel videos to the forwarding server which forwards corresponding videos to the terminal needing video transmitting; when the forwarding server forwards the corresponding videos to the terminal needing video transmitting, the forwarding server updates terminal information and the start and close of sub threads through a main thread, the transmission of videos is achieved through the sub threads, and each of the multi-channel videos corresponds to an independent sub thread, and each of the sub threads corresponds to a port number. According to the multi-video forwarding method based on port numbers and IP addresses, concurrent execution and no mutual interference among sub threads are guaranteed; further, the start and close of sub threads is achieved, not only simultaneous forwarding of multi-channel videos is guaranteed, but also the occupied bandwidth of reduced threads is prevented, and video transmission cost is reduced, so that the effect of video transmission is good.

Description

technical field [0001] The invention relates to a video forwarding method, in particular to a multi-video forwarding method based on port numbers and IP addresses. Background technique [0002] In the field of video transmission, usually the video server directly provides video data to the terminal, such as figure 1 shown. However, when multiple terminals request video transmission from the video server at the same time, in order to ensure the smoothness of video transmission, a larger broadband must be opened, otherwise the video transmission effect will not be good, resulting in the current high cost of video transmission, and when multiple When two terminals request the same channel of video transmission from the video server, it will cause a lot of pressure on the video server. [0003] In addition, the current video server transmits the locally stored video to the terminal, but in some fields such as video surveillance, it is required to realize video collection while...

However, when multiple terminals request video transmission from the video server at the same time, in order to ensure the smoothness of video transmission, a larger broadband must be opened, otherwise the video transmission effect will not be good, resulting in the current high cost of video transmission, and when multiple When two terminals request the same channel of video transmission from the video server, it will put a lot of pressure on the video server.

[0003] In addition, the current video server transmits the locally stored video to the terminal, but in some fields such as video surveillance, it is required to realize video acquisition while video transmission, which cannot be achieved only by using the video server
