What You Should Know About the Transmitter and Receiver in Wireless Video Transmission

Wireless Video

The image transmission system is an important part of the communication system. An image transmission system transmits an image from one place to another. It consists of a transmitter and a receiver. The transmitter converts the image into electrical signals and sends them to the receiver. The receiver receives the electrical signals and converts them into digital signals. The digital signals are then sent to a computer or other device that interprets them and sends them to the intended destination.

The development of the image transmission system has been a great boom for the industry. With the development of this new technology, we have seen a rise in the number of people who are able to communicate with each other using this technology. In addition, the development of this new technology has also allowed us to communicate with people who are far away from us, such as astronauts or those on the other side of the world.

How Does a Wireless Video Transmission System Work

Using a wireless video transmission system, signals can be sent from one place to another or, even better, from one device (transmitted) to another. The same is true for videos.

These systems come in a wide variety of designs and each has a unique set of features and advantages, but they all aim to achieve the same thing: to deliver an uninterrupted image and video signal without the use of cables or wires.

This process is both quite simple and extremely complex. That is to say, while the fundamental idea—that a video signal is transmitted wirelessly from a transmitting device to a receiving device—is fairly simple to grasp, the underlying technology is quite complex.

The device that receives audio and video input from another input device is known as the transmitter. The receiver decodes and outputs the video and audio signals through a visual medium like a TV or monitor after the signals have been wirelessly transmitted by the transmitter to it.

Radio frequency (RF) waves are used by wireless video transmission systems to transmit signals from one location to another. These systems use RF waves that are comparable to those used by wireless devices like cell phones, Wi-Fi routers, and other wireless technologies. This technique enables good video quality and very low latency (up to 1080p for now).

The primary distinction is that wireless video transmission systems use RF waves that were created specifically for the transfer of videos, not data. As was already mentioned, the transmitter converts the video signal into RF waves, which are then transmitted through the air to the receiver.

The signal is output to a display device after the receiver decodes it. The use of RF waves by various wireless devices can interfere with one another, which is an important consideration because it limits how far the signal can travel. The signal will become weaker if it is farther from the receiver, and eventually there will be too much interference for the receiver to properly decode the signal, leaving you with a blank screen. However, as long as you are within the covered range, you won’t experience increased latency or choppy images. These things rely on RFs and either function flawlessly or they don’t. There is no in-between.

How to Choose a Good Wireless Video Transmission System

  1. Transmission Distance

Depending on the actual shooting distance and any obstructions, a wireless video system’s transmission distance can vary. Therefore, you might need to be aware of the required video transmission distance and the potential number of obstacles between the transmitter and receiver in advance.

Line of sight and non-line of sight distances are two categories for the range of video transmission. Because obstructions will significantly reduce the transmission distance, one wireless video transmission system supports transmitting over longer distances when it is in line of sight than when it is not.

So, before purchasing a wireless transmission device, conduct a thorough analysis on the shooting environment. A mid-long-range HDMI transmission system, for instance, could be the perfect partner if you plan to send HDMI videos to backstage or spectator seats.

  1. Latency

The latency in wireless video transmission may have a significant impact on your work. It is better to understand how much latency the transmission system generates and estimate the effects it might have on your video.

The video quality will significantly decline if the picture and audio are out of sync or if other sync issues arise. The higher-quality system you might need depends on how much latency you want to have.

  1. Connectivity

Finding out what video equipment you use as an input source and an output destination is a must first. Some kits offer SDI, HDMI, or both as inputs and outputs. One video transmission system with compatible interfaces for your devices is available for your selection.

What to Use: Product Recommendation

More and more video producers are devoted to creating videos with a variety of themes in a variety of settings, and multi-angle shooting can enhance their videos. If you have similar requirements and are looking for a more comprehensive and professional system, consider the Hollyland Mars 4K wireless video transmission system.

The Hollyland Mars 4K can reduce recording noises and ensures clear audio, making post-production work more efficient. Meanwhile, the low power consumption results in increased battery life and allows it to be powered by USB Type-C or NP-F batteries. With the Mars 4K transmission system, you can shoot longer and richer videos while also having portable charging options outside.

Long-distance and high-definition transmission are important aspects of a wireless video system. The Hollyland Mars 4K could work within 450ft (150m) feet in line of sight with the receiver and in 0.06s latency, giving you more freedom in choosing shooting and monitoring locations.

With HDMI and SDI inputs and outputs, it supports up to the 1080p 60Hz video format and delivers uncompressed 4K wireless video transmission, allowing you to shoot and transmit high-definition videos with a variety of professional devices.

Conclusion

When it comes to videos, nothing beats the convenience of wireless video transmission systems. Whether you need a portable solution for shooting interviews or you need a fixed system for live events, you can use the Hollyland Mars 4K for all your video needs.
