Un guide d'achat intégré sur le modulateur HDMI RF

À l’ère du numérique, Le modulateur HEMI RF est un appareil électronique indispensable non seulement pour les ménages mais aussi pour les sites publics. Donc dans ce texte, nous vous proposerons un guide intégré sur la façon d'acheter un modulateur HDMI RF, y compris sa définition, avantages, considérations d'achat, et cinq conceptions de modulateurs recommandées.

Pouvez-vous convertir HDMI en RF?

Premier, prepare an AV line and a coaxial cable signal line. Seconde, insert one end of the AV line into the AV input port of the converter, and then connect the other end to the AV output port of the set-top box. La troisième, the coaxial TV signal cable should be inserted into the RF input port of the TV and the RF output port of the converter.

What Is HDMI RF Modulator?

HDMI radio frequency modulator is a processor for converting the video and audio signals of high-definition HDMI to digital signals. Carrying with a professional RF converting technique, it transports the multi-channel radio frequency signal through a coaxial cable. The receiver restore the radio frequency signal to high-definition audio and video signal which can be displayed by the TV.

It can be applied in various situations. Such as

  • Security monitoring system
  • Multimedia information publishing system
  • Digital signage HD transmission
  • Home cable TV system
  • HD video conferencing system
  • Train vehicle and platform HD video transmission
  • Bus station passenger information display system
  • Airport multimedia information release system
  • Supermarket and store HD advertising system

Is An RF Modulator The Same as A Digital Converter?

They are not the same in working principle and application.

A digital converter is an electronic device for converting one form of digital data into another. Par exemple, a digital converter can convert an analog signal to a digital signal, or reversely a digital signal to an analog signal. C'est-à-dire,a converter box demodulate a signal but also is capable of decoding any encrypted data in the signal. The device is commonly applied to computers, communication system, control system and measurement system.

En revanche, RF modulator is used for modulating a certain frequency with an injected video or audio signal.

Benefits of Using An HDMI RF Modulator

HD Transmission

HDMI signal transmitters support HD resolution and multiple audio formats, such as Dolby Digital and DTS. It offers clear and realistic audio-visual experience to users.

Long-distance Transmission

HDMI signal transmitters extend the transmission distance of HDMI signals, allowing users to use high-definition devices in different rooms.

Stable Transmission

The HDMI signal transmitter ensures the stable transmission of the signal and avoid signal interruption or distortion, so users would have a smooth, stay-free high-definition audio-visual entertainment experience.

Multi-device Connection

HDMI signal transmitters can connect multiple devices at the same time, giving users the freedom to use different devices without limitation.

Factors to Consider When Choosing An HDMI RF Modulator

When choosing an HDMI cable transmitter, the first thing you need to determine is how long the transmission distance. En général, the HDMI cable transmitter signal can reach above 70-100 meters long through a single CAT5E/CAT6/CAT7 cable. If your required distance is only 50 mètres, you can choose the type with 70-meter transmission long.

en plus, it is necessary to check whether the HDMI cable transmitter supports the required high-definition format. Par exemple, the device with transmission distance of 100 meters supports 1080P resolution ratio, while the device with 70-meter transmission 4K60 resolution ratio.
