Embodiment 1

[0062] figure 1 It is a process schematic diagram of a video transmission method provided by an embodiment of the present invention, and the process includes the following steps:

[0063] S101: The outdoor station receives a video acquisition control command sent by the indoor unit, and the control command carries target identification information of the IPC to acquire the video.

[0064] The video transmission method provided by the embodiment of the present invention is applied to an outdoor station in a building intercom system, where the outdoor station refers to a device at the door with a video monitoring function.

[0065] In order to avoid potential safety hazards in the direct interaction between the indoor unit and the IPC, the architecture of the video transmission system provided in the embodiment of the present invention is as follows: figure 2 As shown, in this system, the indoor station is connected to the outdoor station, and the IPC that needs to obtain vide...

Embodiment 2

[0076] In order to further ensure the security of video transmission, on the basis of the above embodiments, in the embodiment of the present invention, before receiving the control command for video acquisition sent by the indoor unit, the method further includes:

[0077] Send a call request to the indoor unit to determine whether to connect;

[0078] If the response message sent by the indoor unit is received, it is determined that a connection has been established with the indoor unit.

[0079] Although the outdoor station and the indoor station are connected by cables, in order to ensure the safety of video transmission and to confirm whether there is any problem with the connection cable, the outdoor station can communicate with the indoor station before receiving the control command sent by the indoor station. Establish a call connection. Specifically, the outdoor station may send a call request to determine whether to establish a connection to the indoor station speci...

Embodiment 3

[0101] Figure 4 It is a process schematic diagram of a video transmission method provided by an embodiment of the present invention, and the process includes the following steps:

[0102] S401: The indoor unit sends a video acquisition control command to the outdoor unit, and the control command carries target identification information of an IPC corresponding to the video to be acquired.

[0103] The video transmission method provided by the embodiment of the present invention is applied to an indoor station in a building intercom system, where the indoor station refers to a device with a video display function located indoors and connected to a door station.

[0104] In order to facilitate the user's use, in addition to the video display function, the indoor unit is also equipped with buttons for sending control commands, such as buttons, virtual dials, etc. When the user wants to obtain the video of a certain IPC, he can press the corresponding Press the key to send a contr...

Abstract

The invention discloses a video transmission method, device and system, which are used to solve the problem of low video transmission security in the prior art. The method includes: the outdoor station receives the control command for video acquisition sent by the indoor unit, and the control command carries the target identification information of the IPC to obtain the video; according to the identification information of each IPC connected to itself, determine the target A target video corresponding to the IPC of the identification information; and sending the target video to the indoor unit.

Description

technical field [0001] The present invention mainly relates to the technical field of security monitoring, in particular to a video transmission method, device and system. Background technique [0002] In the existing building intercom system, the equipment located at the door with video monitoring function is called outdoor station, which is used to monitor the outdoor area, and the equipment located indoors with the function of providing monitoring video display for users is called indoor station. Indoor users can monitor the outdoor situation, and the indoor unit is generally directly connected to the outdoor unit. Due to the limitation of the camera angle and parameters of the outdoor station itself, in order to achieve all-round monitoring, it is necessary to install other auxiliary monitoring equipment such as an IP camera (IPCamera, IPC) for the outdoor station. In order to facilitate the indoor station to provide users with the information of all monitoring areas, t...
