Embodiment Construction

[0081] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below through specific embodiments and with reference to the accompanying drawings.

[0082] The embodiment of the present invention provides a device for invoking the OSD menu in the camera that does not require additional laying of cables and does not need to be operated on the camera end, including the camera end and the local monitoring end connected to each other through a coaxial cable, Such as figure 2 shown. Both the local monitoring terminal and the camera terminal are powered by the power cable. The local monitoring terminal can be monitored by various devices, such as SDI-DVR, etc., which are known to those skilled in the art, and will not be described in detail in the present invention.

[0083] The local monitoring terminal includes: the buttons corresponding to the OSD menu, the first single-chip microcompute...

Abstract

The invention discloses a device for accessing an OSD (on-screen display) menu in a camera. The device comprises a camera end and a local monitoring end which are connected through a coaxial cable, wherein the local monitoring end comprises keys corresponding to the OSD menu, a first single chip microcomputer, an amplitude modulation circuit and an attenuation and isolation circuit which are connected sequentially, and the camera end comprises a filtering and isolating circuit, a shaping processing circuit, a demodulation circuit, a level switching circuit, a second single chip microcomputer and a video processing unit. The device has the advantages that key operation is only required to be performed at the local monitoring end, and key operation information is processed by the first single chip microcomputer and the amplitude modulation circuit prior to being superposed in video signals transmitted by the coaxial cable, then is processed by the filtering and isolating circuit, the demodulation circuit and the second single chip microcomputer at the camera end and then is demodulated and transmitted to the video processing unit, so that video signal transmission and OSD menu accessing by one coaxial cable are achieved. The invention further discloses a method for the device.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a device and method for calling an OSD menu in a video camera. Background technique [0002] A camera is a device that can convert optical image signals into electrical signals. It has many applications, such as being installed on a monitoring site, and connected to a local monitoring terminal through a coaxial cable, converting the obtained image into an electrical signal and sending it back to the The local monitoring terminal is used for monitoring. [0003] SDI camera is a camera equipped with SDI interface (serial digital interface, digital component serial interface), which has small delay, low codec loss, low bandwidth, and real-time high-definition video recording. It is often used in monitoring systems. [0004] For SDI cameras, generally adjust the working indicators of the camera by adjusting the OSD menu. OSD is the abbreviation of on-screen display, that i...
