Understanding Internet Speed & 4K Streaming Quality
Understanding Internet Speed
Before we explore about 4K streaming internet speed, let’s begin with understanding internet speed because many people still don’t know about upload speed and download speed.
Internet speed refers to the rate at which data is transferred between your device and the internet. It is typically measured in terms of upload speed and download speed, which represent the speed of data transmission in different directions.
- Upload Speed: Upload speed refers to the rate at which data is sent from your device to the internet. It is relevant when you perform activities such as live streaming, uploading files to a cloud storage service, or sharing content on social media platforms. Upload speed is measured in megabits per second (Mbps) and determines how quickly you can transmit data to the internet. Higher upload speeds enable faster uploading of files and smoother video conferencing or live streaming experiences.
- Download Speed: Download speed, on the other hand, refers to the rate at which data is received from the internet to your device. This is the most commonly referenced metric when it comes to internet speed, as it affects activities like browsing websites, streaming videos, or downloading files. Download speed is also measured in Mbps. A higher download speed allows for faster loading times of web pages, quicker downloads of files, and smoother streaming experiences without buffering.
So, your question about “4K streaming internet speed” is actually refers to upload speed needed for 4K streaming. You need to know the detail of upload speed and download speed provided by your internet provider.Some internet providers offer higher download speed than internet speed, some offer vice versa.
Measuring Internet Speed
Internet speed is typically measured in Mbps (megabits per second), not MB/s (megabytes per second). Mbps represents the rate at which data is transferred, while MB/s represents the actual size of the data being transferred. It’s important to note that there are 8 megabits in 1 megabyte. Therefore, a connection speed of 25 Mbps would translate to 3.125 MB/s.
When it comes to media streaming platforms, they generally provide recommendations for internet speed in terms of megabits, not megabytes. For instance, Amazon Prime recommends an internet speed of 5 Mbps, not 5 MB/s.
To estimate your download speed in Mbps, you can divide your internet speed by 8. For example, if you have a 100 Mbps internet connection, you can expect a download speed of around 12.5 Mbps.
It’s crucial to use the correct unit (Mbps) when discussing internet speed, as it accurately represents the rate at which data is transferred. Using the incorrect unit (MB/s) can lead to confusion and inaccurate calculations.
Definition of 4K Streaming Quality
4K streaming refers to the transmission and playback of video content at a resolution of 3840 x 2160 pixels, which is four times the resolution of standard high-definition (HD) content. This higher pixel count translates into sharper details, vibrant colors, and a more immersive viewing experience.
Several factors influence the quality of 4K streaming. Firstly, the source of the content plays a crucial role. Streaming platforms that offer native 4K content provide the best visual experience. Additionally, the video compression techniques used by these platforms impact the overall quality. Internet speed is another critical factor that directly affects the streaming quality, and we will discuss this in more detail in the following sections.
Determining 4K Streaming Internet Speed Requirements
The internet speed for streaming 4K depends on various factors, including the streaming platform’s recommended bitrate and the bandwidth.
The specific upload speed you need depends on the type of compression used for the video. Use the following guidelines to estimate the required upload speed for 4K streaming.
Most software and hardware encoders utilize H.264 (AVC) compression for video. However, some newer encoders, like the BoxCaster Pro, employ H.265 (HEVC) compression, which requires only half the bandwidth of AVC. If you’re interested in learning more, refer to an article that delves into the differences between H.264 and H.265.
Streaming 4k Bandwidth
Even with effective compression, 4K video content demands a significant amount of bandwidth. For example, YouTube recommends an upload speed of 34 Mbps for streaming 4K at 30 frames per second (fps), and 51 Mbps for streaming 4K at 60 fps.
In addition to accommodating high internet speeds for 4K streaming, you should allocate additional 4k streaming bandwidth for audio (typically in the range of 128–320 Kbps) and a small overhead.
How much bandwidth does 4k streaming use?
It’s advisable to double the required 4k streaming bandwidth to ensure you stay at 50% or below of your available bandwidth, allowing for potential disruptions.
For instance, if you are streaming a 4K / 2160p at 30 fps broadcast to YouTube, you might allocate13,000–34,000 Kbps for video, 384 Kbps for 5.1 surround sound, and 50 Kbps for overhead.
If we take the maximum bitrate for video, the total is 34,000 + 384 + 50 = 34,434 Kbps. Doubling this total leads to a minimum requirement of 68,868 Kbps for your overall available bandwidth.
By utilizing this formula, you can arrive at a reasonable estimation of the necessary upload speed for your 4K live stream. However, it’s crucial to also consider the importance of transcoding and its role in optimizing the streaming process.
4K streaming internet speed usually require 35 Mbps. But to account for potential disruptions, it is recommended to allocate double the required 4k streaming bandwidth.
Transcoding is crucial in your live streaming setup, particularly if your streaming service lacks cloud transcoding. It involves sending a high-quality bitrate stream to the provider, who then creates lower bitrate versions for viewers with varying internet capabilities. This adaptive bitrate streaming prevents buffering and viewer drop-off.
Streaming multiple bitrates allows the player to adjust stream quality based on the viewer’s connection. For instance, sending a 1080p stream at 6 Mbps enables the provider to offer options like 4 Mbps, 2 Mbps, and 1 Mbps. The highest-quality version suitable for the viewer’s connection is automatically selected.
Without cloud transcoding, you must send each bitrate yourself, increasing bandwidth requirements. In the example above, allocating bandwidth for the various bitrates totals 13 Mbps. Doubling this for safety results in a 26 Mbps bandwidth requirement for the video alone.
Lacking transcoding support means manually providing each bitrate, demanding more bandwidth and limiting scalability and accessibility of your stream. Watch the video below to further your understanding:
