The world of streaming and multimedia is undergoing 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 getting the most out of streaming, gaming, and digital entertainment platforms. In this analysis, we'll explore the most innovative cable technologies 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, representing 44.8% of total television viewing, surpassing for the first time the combined total of broadcast and traditional cable television. This 71% growth since 2021 is due to the ease of access, image quality, and personalization offered by digital platforms.
However, this boom does not mean the end of cables: 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.
Main 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 televisions, monitors, game consoles, and streaming devices. The latest versions, such as HDMI 2.1, allow for the transmission of 4K and 8K video 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, digital optical (Toslink) and coaxial cables remain relevant. They allow for the transmission of multichannel audio (Dolby Digital, DTS) with minimal interference and no loss of quality, essential for home cinema experiences.
3. USB-C and Thunderbolt cables: versatility and speed
USB-C has established itself as the universal connector for modern devices. Its ability to transmit data, video (DisplayPort Alt Mode), and power makes it the preferred choice for laptops, tablets, and smartphones. Thunderbolt 4 , based on USB-C, offers speeds of up to 40 Gbps, allowing you to connect 8K monitors, workstations, and high-performance external drives.
4. Cat 6/6A/7/8 Ethernet Cables: The foundation of stable connectivity
Although Wi-Fi is ubiquitous, Ethernet cables remain indispensable for high-quality streaming, competitive gaming, and video conferencing. The most advanced categories (Cat 6A, Cat 7, Cat 8) support speeds up to 40 Gbps and offer low latency, interference immunity, and stability in home and business networks.
Main benefits:
- They eliminate buffering and connection drops in 4K/8K streaming.
- Ideal for smart homes and offices with multiple connected devices.
5. Fiber optics: the future of data transmission
Fiber optics is the most advanced technology for transmitting data over long distances at high speeds. Although its use in homes is still limited by cost and infrastructure, more and more homes and businesses are adopting FTTH (Fiber To The Home) connections, allowing simultaneous streaming on multiple devices without loss of quality.
Emerging trends: Goodbye to cables?
Although the trend is towards wireless transmission (5G, Wi-Fi 6/7, fixed wireless internet), cables are still essential to ensure maximum quality and stability, especially in professional and demanding environments.
Main trends:
- IP Transmission: The future points to the gradual elimination of cables in studios and production companies, but at home, cables remain the most reliable option for high-quality streaming.
- Smart home integration: Modern cables allow the integration of multimedia systems with voice assistants, home automation, and IoT devices, creating immersive and personalized experiences.
- Wired-wireless hybrid: Many devices offer hybrid connections, allowing you to switch between wired and wireless as needed, optimizing the user experience.
