The acronyms HD, 4K and 8K indicate increasing amounts of pixels and different levels of detail; fiber optics makes it possible to watch high-resolution content without the interruptions or buffering typical of older connections.
Today, the most practical choice is to let apps handle automatic quality adjustment. In the past, lowering the resolution was the quickest remedy against freezing and constant loading; today, on the other hand, a good ultra-fast connection can support even 4K streaming without particular difficulty.
To get higher-quality images, however, you also need content available in high resolution, an adequate subscription, and compatible devices or screens.
Pixels and definition: the differences to know
The acronym HD normally indicates a resolution of 1280 × 720 pixels. Full HD, now very widespread, brings the image up to 1920 × 1080 pixels. 4K Ultra HD rises to 3840 × 2160 pixels, quadrupling the pixels of Full HD. 8K reaches 7680 × 4320 pixels, offering four times the pixels of 4K.
As resolution increases, so does definition and the visibility of small details. The difference is more noticeable on large TVs viewed from a short distance. On a smartphone, however, the shift from Full HD to 4K can be hard to perceive. Sharpness also depends on the compression applied by the streaming service.
A heavily compressed 4K video can look less convincing than good Full HD. In this scenario, ultra-broadband makes it possible to manage high-definition video streams with greater speed and stability, reducing the risk of interruptions even when several devices are connected at the same time. HDR, brightness, contrast and panel quality also contribute to the final result.
To watch in 4K, you also need a title, a plan and a device that support it. 8K remains mainly a technology for compatible screens, with native content still limited.
Why FTTH fiber is the future of streaming
During streaming, a movie isn’t downloaded in full before playback. The app receives small video segments and temporarily stores them in a buffer – a small memory area where some data is accumulated before being played. This way, the video can keep playing smoothly even with brief variations in connection speed. If the connection doesn’t deliver data fast enough, playback can stall. To avoid this, the service automatically lowers the video’s resolution and bitrate.
Fiber optics connections, on the other hand, offer speed and stability far superior to older lines. For this reason, it’s no longer necessary to preemptively choose a lower quality at home. A fast line can support 4K even while other devices are using the internet.
Actual performance still depends on the contract, the home network and Wi-Fi. Walls, distance from the router and interference can reduce the speed received by the TV. For main screens, it’s best to use an Ethernet cable or a modern, stable Wi-Fi connection.
Apple, for example, recommends a connection of at least 25 Mbps for its own 4K content. And if interruptions occur, it’s worth checking the network first before limiting quality.
Open Fiber and the spread of the FTTH network
In Italy, Open Fiber contributes to the spread of ultra-fast connectivity through FTTH and FWA networks. The acronym “FTTH,” Fiber To The Home, indicates that fiber optics reaches directly inside the home or office. The absence of the traditional final copper stretch makes it possible to achieve ultra-fast, stable and responsive connections, helping to reduce the digital divide.
In areas where bringing an ultra-fast connection all the way to buildings is more difficult, FWA technology, “Fixed Wireless Access”, completes coverage through a radio link between an antenna and the user’s home.
A solution that makes it possible to extend ultra-broadband connectivity even to the small towns and villages that are hardest to reach.
FTTH and FWA can support high-definition streaming, remote work, cloud services and online gaming, with actual performance depending on the technology and the plan activated. Open Fiber builds, manages and maintains the infrastructure, but does not sell subscriptions directly to end users.
In fact, after checking coverage at their address, users can choose one of the available Partner Operators and find out which technology is available in their area.
The project involves major cities, small towns, industrial areas and territories included in public cabling plans. Check now if your address is covered by Open Fiber’s fiber optics network.
