Problems solved by technology

[0002] The existing wired cameras use wired transmission, because the reason of the transmission line seriously limits the flexibility of the camera, which brings a certain degree of inconvenience to users
Followed by wireless cameras based on WIFI and 3G / 4G wireless technology transmission, although they can get rid of the shackles of transmission lines, the high delay of WIFI and the low bandwidth of 3G / 4G cannot satisfy people's pursuit of high-definition video signals
[0003] The existing WIFI and 3G / 4G wireless technology wireless cameras cannot meet the transmission of ultra-high-definition video signals, and some even cannot meet the transmission of high-definition video signals, and the high delay of the existing WIFI and 3G / 4G wireless cameras leads to There is a large time difference between the monitoring terminal and the camera screen, which makes the user unable to control the scene in time, and the background cannot perform secondary processing on the received non-high-definition signal

Embodiment 1

[0037] This embodiment provides a wireless camera, including an electronically controlled lens, an image sensor, a video signal processor, a video compressor, a video output format selection switch, and a 5G terminal module; the electronically controlled lens collects and transmits the optical signal of the scene image to the image sensor Input terminal, the output terminal of the image sensor is connected to the input terminal of the video signal processor, and the output terminal of the video signal processor is respectively connected to the input terminal of the video compressor and the first input terminal of the video output format selection switch, and the output terminal of the video compressor Connect the second input terminal of the video output format selection switch. The output end of the video output format selection switch is connected to the input end of the 5G terminal module, and the wireless port of the 5G terminal module communicates with the 5G micro base sta...

Embodiment 2

[0057] The difference from the first embodiment is that the wireless camera of this embodiment also includes an electronically controlled pan / tilt, which is used to switch the shooting angle of view and scene. The control end of the electronically controlled pan / tilt is connected to the control end of the 5G terminal module.

[0058] The control method is: the wireless port of the 5G terminal module receives the pan / tilt control signal sent in the background, and the signal demodulator of the 5G terminal module demodulates it and sends it to the control terminal of the electronically controlled pan / tilt through its control terminal to control the electronically controlled pan / tilt. Shooting angle of view and scene switching.

Embodiment 3

[0060] On the basis of Embodiment 1 or Embodiment 2, the wireless camera also includes a built-in identity recognition module, which can be a SIM card or a soft SIM card function module, and the wireless camera is connected to a 5G micro base station or a 5G macro base station. It is used to identify the wireless camera to which it belongs. When the 5G micro base station or 5G macro base station is connected to multiple wireless cameras, it is convenient for the wireless control of the on-site camera in the background.

[0061] The identity of each camera is identified through the exclusive information in the SIM card. The SIM card is like a person's ID card, and each card has its own unique information. The video signal frame transmitted by each camera through the 5G module contains the information of the SIM card installed in the camera. The video signal frame of each camera is demodulated in the background; the control signal frame sent to the wireless camera in the background ...

Abstract

The invention provides a wireless camera and a video signal processing method thereof. The electric control lens is used for focusing and miniaturizing a scene picture; imaging is carried out by an image sensor, the image sensor converts an optical signal of a scene picture into an electric signal and sends the electric signal to the video signal processor for video coding and front-end special effect processing. After processing is completed, the video signal is divided into two paths, one path of the signal is sent to a video compressor to be compressed into a compression code in an H.265 format and then sent to a video output format selection switch, and the other path of video signal source code is directly sent to the video output format selection switch; and the video output format selection switch outputs a compression code or an original code to the 5G terminal module and sends the compression code or the original code to the background through a wireless port of the 5G terminal module. The video signal transmission of the camera based on the 5G technology is low in time delay and strong in sense of immediacy, and is very suitable for the transmission of aerial photographysignals and can be used for transmiting high-definition and ultra-high-definition audio and video signals.

Description

Technical field [0001] The invention relates to a camera, in particular to a wireless camera and a video signal processing method thereof. Background technique [0002] Existing wired cameras use wired transmission, because their transmission lines severely limit the flexibility of the cameras and bring a certain degree of inconvenience to users. What follows is the wireless camera based on WIFI, 3G / 4G wireless technology transmission. Although it can get rid of the shackles of the transmission line, the high latency of WIFI and the low bandwidth of 3G / 4G cannot satisfy people's pursuit of high-definition video signals. . [0003] Existing WIFI and 3G / 4G wireless technology wireless cameras cannot meet the transmission of ultra-high-definition video signals, and some cannot even meet the transmission of high-definition video signals, and the high latency of the existing WIFI and 3G / 4G wireless cameras There is a large time difference between the surveillance terminal and the came...
