What is EFP?
In the current broadcast and television industry, there are more and more mobile entertainment programs, and the OB truck system that TV stations equipped with has relatively high requirements for the program venue, so it shows great limitations when recording such programs. So EFP is appeared. Electronic field production (EFP) is a television industry term referring to a video production which takes place in the field, outside of a formal television studio, in a practical location or special venue.
At present, the appearance of the EFP system in broadcasting industry is very different, but the internal structure is not much different, that is: with the video switcher as the core, the camera generally uses a portable integrated camcorder, the power supply uses an on-board battery or a power supply with an adapter, the recording method uses a hard disk recorder, and the monitoring system use a rack-mount small size monitor or a portable 1U pull-out monitor, the signal transmission uses coaxial cable, the transmission distance is generally within 50 meters, independent tuning system and internal intercom system (now developed into wireless transmission and wireless communication).

EFP: How to choose a monitor?
Generally, the small EFP system is 4 channels (including camera, switcher, switch panel, hard disk recorder, HD monitor, fiber converter or wireless transmission). As convenience is the biggest advantage of EFP, it is generally integrated in the mobile box. Therefore, TV station uses it for featured story, and the TV shopping uses it for the promotion of commodities, the planning and packaging department used it for the outdoors shooting of program propaganda etc., highlighting the great advantages of the EFP system.
Determine the demand
First, since it is integrated in the flight case, the monitor is small, light, and does not occupy space. What’s more, a monitor for EFP must meet the standards of broadcasting. Finally, according to the customer's application, users can choose to use broadcast-level monitors or reference-level monitors.
Second, know about the monitor performance
After making sure monitor level according to the user's environment requirements, you can get a deeper understanding of the monitor's performance. Accurate color reproduction, color gamut, unique functions and user-friendly design are all points of concern.
Third, know about the color calibration and after-sales service of monitor manufacturers
As a product with a high usage rate, the monitor will cause problems such as screen color decay and color distortion after long-term work. This is a common problem of electronic products. At this time, the color calibration services of each manufacturer and its after-sales service are very important, and you can pay more attention to it when buying.
How to choose the right monitor
Everyone knows that large-size monitors have stricter requirements for image processing. In general, we conduct comparative tests through professional test signals, and we can see the display status of various indicators on the monitor through the test signals. We can also use a piece of video material to see if its performance on the monitor is satisfactory to you.
Here, according to the current market demand, we recommend several Konvision monitors that meet the EFP application environment.
NO.1 Broadcast-level pull-out monitor KFM-1753W
If the monitor is used for program monitoring or live broadcasting, we recommend the broadcast-level pull-out monitor KFM-1753W. The advantage is that it occupies little space to facilitate storage.

NO.2 Reference-level pull-out HDR monitor KFM-1760D
If the monitor is used for high-end demand such as feature films and documentaries by department of TV station, users can choose the reference-level pull-out HDR monitor KFM-1760D.
1. Professional performance
16.5 inches, 1RU, 1920*1080 FHD resolution, IPS LCD panel, the color gamut of the LCD panel reaches more than 98% of the P3 standard, wide viewing angle. It supports dual-channel SDI image real-time monitoring. Both SDI1, SDI2 and HDMI support waveform, vectors, histogram and other professional broadcast features. What’s more, it supports unique pixel measurement, signal alarm and HDR display functions.
2. Humanized design
Rear interface—To avoid the wiring problem and make it more convenient, the signal line is deliberately changed to the back.
It supports AC-IN and DC-IN power supply which is more convenient for customers (Only KFM-1760D support)
