Why Use Cables in a 480p Transmission?: Stability and Compatibility Benefits

In the modern era of digital technology, it’s common to question the relevance of using cables for 480p transmissions. However, numerous old monitors continue to serve their purpose, especially within families and small businesses. This article explores why you should consider utilizing cables for your 480p transmission and provides detailed explanations, additional examples, and a closer look at the aspects that make this choice advantageous.

Why Use Cables for 480p Transmission?


  1. Stability:**

    Analog signals, transmitted through cables, are more stable than digital signals. This stability results from the absence of compression during transmission, which makes analog signals less susceptible to interference from electromagnetic fields or other sources of noise. This is particularly crucial for 480p transmissions, as older monitors may not be equipped with advanced error correction technologies present in digital displays.

  2. Compatibility: Older analog equipment such as CRT (Cathode Ray Tube) monitors may not support digital connections like HDMI or DVI. Instead, they require RCA or S-Video inputs, which are compatible with coaxial cables. Therefore, using cables for 480p transmission ensures that these legacy devices can still function effectively.

Recommended Cables

When transmitting 480p signals using cables, it’s essential to employ completely shielded coaxial cables with an RG-62/UF cable for optimal performance. Coaxial cables are suitable for high frequencies and have minimal signal loss due to their design. The shielding on these cables protects the signal from electromagnetic interference, ensuring a stable transmission.

Real-life Example

Consider a small business scenario where an owner faced constant signal loss issues with their old monitors connected via HDMI to the digital computer network. After attempting various solutions, switching to completely shielded coaxial cables resolved the issue. This change not only restored the functionality of the displays but also provided a more stable transmission, improving overall productivity.

In conclusion


Analog signals over cables offer stability and compatibility benefits for 480p transmissions. The stability ensures reduced risk of signal loss with older monitor displays, while the compatibility allows legacy devices to continue functioning effectively. Employing completely shielded coaxial cables, such as RG-62/UF cables, is an effective solution that addresses both concerns. By understanding these benefits and applying them in practical scenarios, you can ensure a reliable and cost-effective transmission system for your 480p applications.
