What is the structure of the professional video camera and what is it used for?

 

ENG Camera function : Only a reporter and editor use this type of camera during news presentation. A single reporter can produce news using a single professional camera or ENG camera, or a television studio crew can produce a live report of an important event at a specific location. A professional camera is sufficient for a small event but an ENG camera is a must for a large program or event. Usually a studio crew with cameras is present to report live on an important event. In this case satellite truck with camera set is required. ENG ক্যামেরার ফাংশনকে মোটামুটি চার ভাগে ভাগ করা যায়।EFP cameras are used to capture the flow of a scene from different angles. For example, a game or sports scene is seen on television, the main object of the game is always in front of the television screen. This is done with EFP cameras. About 22 EFP cameras are needed to broadcast a game in a stadium. A camera does not cover the entire field. Each camera provides coverage of a different part of the field, so that the main content is never missing. In this case all the cameras are controlled and coordinated from the control room. Such cameras are used not only in sports but also in any important meeting.

In the television industry, EFP (Electronic Field Production) is a camera used in video production in various locations, especially outside the studio. We can call EFP camera a combination of ENG camera and studio technique. ENG Camera makes it very accessible and usable. Its production quality is controlled by studio techniques. It has to adapt easily to any environment to operate in a particular place. This requires good lighting management and audio recording assurance. EFP cameras can be used anywhere, outdoors or indoors. But this requires skilled and experienced and perfect planning.

Advantages of remote control camera (Mention the merits of remote controlled camera): Remote control camera is basically a small camera, which can be placed anywhere. Currently it is deployed on drones. Especially those angular locations that the cameraman cannot In places where it is not possible for a human to climb, the camera is placed with the help of a drone or by spreading it like a spider's web. You will often see a camera moving around the field like a spider during a game in the stadium, it is called a spider camera. This is also a remote control camera. It is controlled from the control room with the help of remote controller.

CPU: The brain of the camera control unit is the CPU. It houses the microprocessor, memory unit and input-output data address and control bus. Communication with all sections is maintained through this. It is through this that the signal is sent to the camera or motor to make any decision. After processing the input from the keypad and various modules, it sends signals to the camera and motor for control.

Power Button/Picture Button: All the units are switched on or off with the power button. Picture button controls any scene capture or still image capture or video mode. This is usually done through a momentary switch or a key pad.

Serial control interface (Serial control interface): Through this, the sequence of control signals is maintained. Sends any signal to the output in sequence. Always provides data to the CPU by receiving a feedback signal from the output.

Real time clock: This clock provides real and accurate time. Timing accuracy is an important issue for automatic control. Time snows or fasts due to the accuracy of the clocks we use. But realtime clock always gives correct time.
