Abstract

An external camera wireless prompt system provided by the invention comprises a host, an emitter and a prompt device. The prompt device is installed on a camera, and the external camera wireless prompt system is configured to encode the switching prompt signals of a guided scheduling switcher through a host and then send the encoded switching prompt signals to the emitter. The emitter sends encoding signals to the prompt device, the prompt device performs determine after decoding the encoding signals, emits prompt information after identifying that the decoded signals are itself control signals, and prompts a cameraman that the current camera is occupied at present so as to prevent the cameraman from causing broadcast accidents in the unwitting condition. The external camera wireless prompt system and device are simple in structure and practical.

Description

technical field [0001] The invention relates to the field of camera guidance, in particular to a wireless prompting system and a prompting device for an external camera. Background technique [0002] In media production systems (such as studios and OB vans), the number of camera channels is certain, and sometimes it cannot meet the requirements of program production, and external cameras need to be connected to the production system to meet production needs. For example, a 6-channel production system can only provide 6 sets of cameras (most of these cameras use a camera controller with a CCU (CameraControlUnit). Yes. But the price is very expensive.), but in a program production, the director needs 8 camera positions, and at this time, another 2 ENG (Electronic News Gathering, electronic news gathering. It belongs to a portable camcorder, generally only video The signal enters the production system, and does not have call and tally.) Camera. In the production system, the Ta...
