Analysis of new technologies in cables for streaming and multimedia

The world of streaming and multimedia is experiencing an unprecedented revolution, driven by technological advancements in cables, connectivity, and devices. Today, choosing the right cable not only guarantees a high-quality audiovisual experience but is also key to making the most of streaming platforms, gaming, and digital entertainment. In this analysis, we will explore the most innovative technologies in cables for streaming and multimedia, their advantages, emerging trends, and how they impact current and future content consumption.

Evolution of multimedia consumption: from traditional cable to streaming

Content consumption has changed radically in recent years. According to Nielsen, in May 2025, streaming reached an all-time high, accounting for 44.8% of total TV usage, surpassing for the first time the sum of broadcast TV and traditional cable. This 71% growth since 2021 is due to the ease of access, image quality, and personalisation offered by digital platforms.

However, this boom does not mean the end of cables: the physical infrastructure remains essential to guarantee the speed, stability, and quality needed to transmit content in 4K, 8K, and immersive experiences such as virtual reality.

Key technologies in cables for streaming and multimedia

1. HDMI Cables: The Standard for Digital Video and Audio

HDMI (High-Definition Multimedia Interface) is the most widely used cable for connecting TVs, monitors, consoles, and streaming devices. Recent versions, such as HDMI 2.1, allow video transmission in 4K and 8K at high refresh rates (up to 120 Hz), support for dynamic HDR, and eARC for high-fidelity audio.

Key advantages:

• Simultaneous transmission of uncompressed digital video and audio.
• Compatibility with low-latency technologies, ideal for gaming and real-time streaming.
• Support for advanced features such as ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate).

2. Optical and Coaxial Cables: High-Resolution Audio

For surround sound systems and soundbars, optical (Toslink) and digital coaxial cables remain relevant. They allow multi-channel audio transmission (Dolby Digital, DTS) with minimal interference and no loss of quality, essential for cinematic experiences at home.

3. USB-C and Thunderbolt Cables: Versatility and Speed

USB-C has become the universal connector for modern devices. Its ability to transmit data, video (DisplayPort Alt Mode), and power makes it the preferred option for laptops, tablets, and smartphones. Thunderbolt 4, based on USB-C, offers speeds of up to 40 Gbps, allowing connection of 8K monitors, workstations, and high-performance external drives.

4. Ethernet Cat 6/6A/7/8 Cables: The Foundation of Stable Connectivity

Although Wi-Fi is ubiquitous, Ethernet cables remain irreplaceable for high-quality streaming, competitive gaming, and video conferencing. More advanced categories (Cat 6A, Cat 7, Cat 8) support speeds up to 40 Gbps and offer low latency, immunity to interference, and stability in home and professional networks.

Main benefits:

• Eliminate buffering and connection drops in 4K/8K streaming.
• Ideal for smart homes and offices with multiple connected devices.

5. Fibre Optic: The Future of Data Transmission

Fibre optic is the most advanced technology for long-distance, high-speed data transmission. Although its domestic use is still limited by cost and infrastructure, more and more homes and businesses are adopting FTTH (Fibre To The Home) connections, allowing simultaneous streaming on multiple devices without loss of quality.

Emerging trends: goodbye to cables?

Although the trend points towards wireless transmission (5G, Wi-Fi 6/7, fixed wireless internet), cables remain essential to guarantee maximum quality and stability, especially in professional and high-demand environments.

Main trends:

• IP Transmission: The future points to the progressive elimination of cables in studios and production companies, but at home, cables remain the most reliable option for high-quality streaming.
• Integration with smart home: Modern cables allow the integration of multimedia systems with voice assistants, home automation, and IoT devices, creating immersive and personalised experiences.
• Hybrid cable-wireless: Many devices offer hybrid connections, allowing switching between wired and wireless as needed, optimising the user experience.

How to choose the right cable for streaming and multimedia?

The choice of cable depends on several factors:

• Desired resolution and image/audio quality: For 4K/8K and surround sound, HDMI 2.1 and optical cables are essential.
• Distance between devices: For long distances, consider active optical cables or fibre optic.
• Device type: Consoles, PCs, Smart TVs, and sound systems may require different types of cables.
• Connection stability and speed: For uninterrupted streaming, Ethernet Cat 6A or higher is the best option.

Frequently asked questions about streaming cables

Is it better to use Wi-Fi or Ethernet cable for 4K streaming?

Although Wi-Fi 6/7 offers impressive speeds, the Ethernet cable is still more stable and reliable for ultra-high-definition streaming, eliminating interference and latency issues.

What HDMI cable do I need for my 8K Smart TV?

To get the most out of an 8K Smart TV, you need an HDMI 2.1 Ultra High Speed cable, which supports the necessary bandwidth for 8K video at 60 Hz and advanced features such as dynamic HDR.

Can I use a USB-C cable to connect my laptop to the monitor?

Yes, as long as both devices are compatible with DisplayPort Alt Mode or Thunderbolt. This allows video, audio, and data to be transmitted through a single cable, simplifying the connection and reducing clutter.

What are the advantages of fibre optic over traditional coaxial cable?

Fibre optic offers much higher speeds, lower latency, and greater simultaneous transmission capacity, ideal for homes with multiple users and connected devices.

The impact of new technologies on the future of streaming

The convergence of high-speed cables, advanced wireless connectivity, and smart devices is transforming the way we consume content. Service providers are adopting hybrid models, integrating streaming, traditional TV, and on-demand platforms into a single, fluid experience. In addition, the emergence of technologies such as ASICs for efficient video compression and transmission allows reducing the necessary bandwidth without sacrificing quality.

The immediate future points to greater personalisation, hyperrealistic image and sound quality, and the full integration of multimedia systems into the smart home ecosystem.
