Embodiment Construction

[0042] The present invention proposes a video data transmission method, which is applied to the situation where a public network device requests video data in a private network device. The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] by figure 1 To refer to the network model diagram, private network devices are in figure 1 The IPC is used as an example to illustrate. Of course, the IPC is only an example, and it can also be other devices with the function of acquiring or saving video. The public network device is in the figure 1 Middle refers to the user device requesting the video data. like figure 2 As shown, the method includes:

[0044] In step 201, the gateway device connecting the public network and the private network maintains the corresponding relationship between the identification information and the IP address information of each IPC device.

[0045] Preferably, in cons...

Abstract

The invention discloses a method and equipment for transmitting video data. The method comprises the following steps: gateway equipment receives a request message for checking video data of private network equipment, from public network equipment, wherein the request message carries identification information of the private network equipment; the gateway equipment determines IP (Internet Protocol) address information of the private network equipment based on the identification information and corresponding maintained relation and informs the private network equipment to transmit the video data by taking an IP address of the public network equipment as a target address based on the IP address information; the gateway equipment receives the video data transmitted by the private network equipment, wherein the target IP address of the video data is the IP address of the public network equipment; and the gateway equipment forwards the video data to the public network equipment. In the invention, the burden of the gateway equipment is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a video data transmission method and equipment. Background technique [0002] With the development of 3G (3rd-generation, third-generation mobile communication) technology, the advancement of operators' network construction speed, and the development of IP (Internet Protocol, Internet Interconnection Protocol) video surveillance technology, more and more IP video surveillance into ordinary households. At present, in the family or SMB (Small and Medium Business, small and medium-sized enterprises), the networking of IP video surveillance and ordinary office networks is as follows: figure 1 As shown, IPC1 (IP Camera, network camera), IPC2, IPC3, client 1, client 2 and the gateway device are located on the private network side, user equipment is located on the public network side, and the private network side and the public network side are connected through NAT (Net...
