The deepening of information technology has made audio-visual systems increasingly complex, which continues to bring new challenges to signal processing and engineering wiring. Of course, in order to keep the environment clean and tidy, even the simplest system can feel the pressure of these challenges.
In order to meet people's high quality requirements for the on-site environment, we usually have to hide equipment and lines when wiring, and do not interact with users to make it disappear in the field of vision. However, in doing so, it will often bring some long-distance transmission problems of high-definition signals. For example, when the limit transmission distance of ordinary HD cables exceeds the limit, the projection signal will be extinguished. In the long-term engineering practice, people have explored a variety of ways to solve this problem, so what are the common ways of coping with it?
Use HD signal extension cable transmission
The high-definition signal extension cable can transmit high-definition signals to forty-five meters, but it has inherent disadvantages such as large, bulky and difficult to bend. In actual engineering wiring, this is not conducive to dealing with a large number of environments with complex spatial structures. We can imagine that a dozen or even dozens of such wires are tied into a bundle of volume and weight. It is also conceivable to bend at the corner. A sense of entanglement. But if the wiring is a straight through to the end, then these concerns are almost negligible.
Transmission using twisted pair transmitter
The twisted pair transmitter can transmit high-definition signals to sixty-seven meters or even hundreds of meters, and is easy to use with cable wiring. The wire material is light and the wire body is almost half of the high-definition signal line and easy to bend. It can be used for wiring in a complicated space environment and easy to hide. In the early days, even single-signal twisted-pair transmitters, like "bricks", have not been able to simplify engineering wiring perfectly. Later, DDMALL introduced a single-signal twisted-pair transmitter that can be directly plugged into the signal interface of the device. At this time, the wiring is almost as easy as using the network cable. The DDMALL twisted pair transmitter can transmit farther in the higher clear signal extension line, the wiring is more convenient and flexible, and the cost performance is higher. At this point, they have become an ideal choice for long-distance transmission of high-definition digital signals, and have provided a great solution for the majority of engineers, integrators and users.
Transmission using fiber optic transmitter
The fiber optic transmitter can transmit high-definition signals to tens of kilometers, and the fiber-optic wires are thinner, lighter and more bendable than Others, so it is impeccable regardless of transmission distance or wiring. In theory, it is a better choice for long-distance transmission, but when used for transmission within 100 meters, its cost performance is completely destroyed by the DDMALL twisted pair transmitter. Of course, if it is used for more than 160 meters (DDMALL twisted pair transmitter is equipped with the corresponding repeater to transmit HD signals to 160 meters), if it is a local tyrant, the price consideration can be ignored.
Using wireless transmission
Wireless transmission does not require any wires, and its convenience is unquestionable. However, the wireless transmission signal is easy to attenuate, and its transmission distance is generally less than 30 meters. This transmission limitation cannot meet the actual needs of the project in many cases. Moreover, its price is several thousand yuan, which is several times that of the high-definition signal line and the twisted-pair matrix. It is difficult to apply a wide range of applications to solve long-distance transmission, both in terms of technology and price.
These commonly used tricks for long-distance transmission have their own characteristics, but to complete HD signal transmission within 160 meters, the best choice is the DDMALL twisted pair transmitter. Its transmission distance can support most engineering systems, cost-effective, and wiring is relatively convenient. If the HD signal transmission distance is too long, the projection signal will be extinguished, and the DDMALL twisted pair transmitter should have a coup!
DDMALL is committed to helping engineers, integrators and users solve the problem of long-distance transmission of high-definition digital signals, simplify the wiring of high-definition audio-visual systems, and let everyone enjoy HD!
