What is bandwidth?
Bandwidth is the chapters of a network to upload and download data. Internet bandwidth is the maximum volume of information you tin can send and receive in a measured amount of time. It'south generally calculated in megabits per 2d (Mbps).
When streaming video to the Internet, you lot are consuming upload bandwidth. It's essential to know your network's available upload bandwidth because it enables (and besides limits) the quality of your outgoing streams.
Available bandwidth depends on the network router, environment, and almost chiefly, the connectedness type. For instance, dial-upward Net had a maximum bandwidth of just 56 kilobits per second (Kbps). In contrast, more modern connectedness types like cobweb-optic landline (622 Mbps), Gigabit Ethernet (one,000 Mbps), and 4G LTE (100 Mbps) have much higher bandwidths.
Bandwidth vs. speed
Various online speed tests offer to test how fast your network is. Just is that the same equally bandwidth? Not quite. "Bandwidth" and "speed" are often used interchangeably, yet at that place is a difference between these ii terms.
If bandwidth is the maximum rate for data transfer, speed is how fast data is factually downloaded or uploaded. Like bandwidth, the connexion speed is also measured in Mbps.
Since live streaming involves uploading data to the Net, having ample upload speed is important. In fact, for successful live streaming, you'll demand both sufficient upload bandwidth and upload speed.
Solutions yous can stake your reputation on
Built for pro AV, Epiphan'due south rugged and reliable hardware encoders let you capture, stream, and record with confidence. Wherever your production teams take them, Epiphan Deject'due south configuration and monitoring streamline management.
As with download speed, upload speed has a set rate (e.g., "5 Mbps upload speed") equally dictated by your Internet service provider (ISP). Because bandwidth sets the upper limit for the data transfer rate, there's no sense in purchasing Cyberspace speeds from your Internet access provider that exceed your maximum bandwidth.
Bandwidth vs. bitrate
Considering raw video and audio are likewise hefty to upload, streamed content needs to be encoded. Encoding compresses video and audio content into a size and format that's piece of cake to send to the Cyberspace.
Bitrate is the amount of data encoded per unit of time. When it comes to streaming, information technology's usually measured in Kbps, and less frequently in Mbps. Mostly speaking, the college the bitrate, the higher the video quality, and the higher the upload bandwidth required.
To encode your content, y'all'll use either a software encoder or a hardware encoder (like Pearl Nano, Pearl Mini, or Pearl-two). You volition set the bitrate in your encoder settings.
The total bitrate consists of the video and audio bitrates. The bitrate setting will depend on the video resolution and frame charge per unit. For higher resolutions and frame rates, you'll demand college bitrate settings. For case, the recommended encoding settings for 4K streaming at 60 frames per second (fps) will be higher than that for 1080p streaming at 30 fps. Insufficient bitrate will cause your stream to announced choppy.
How much bandwidth do I need for live streaming?
The amount of bandwidth you lot'll need depends on your encoding bitrate. For example, if you lot are encoding at 3,000 Kbps, y'all will demand at least 3 Mbps of upload bandwidth. If your stream'due south bitrate is too loftier relative to your upload bandwidth, your live stream will be unreliable for viewers. For instance, a stream with a half dozen,000 Kbps bitrate doesn't piece of work on a network with a v Mbps upload bandwidth limit.
Above are the full general required bandwidth for streaming guidelines. For example, the minimum bandwidth required for 1080p (HD) streaming is 5 Mbps, while the minimum 4K (UHD) streaming bandwidth is effectually 25 Mbps.
Different platforms (east.g., YouTube, Twitch, Facebook) have different speed requirements and recommended encoding settings. And then be certain to double-check before streaming.
How to ensure y'all have plenty bandwidth for streaming
It's simple math to realize that if y'all have 5 Mbps of upload bandwidth, your stream bitrate should be less than 5 Mbps. Only merely how much less? Bandwidth limitations are only part of the story! Y'all'll need to consider some additional factors to ensure the success of your live stream.
Always have some extra bandwidth (and upload speed) available
Ensure you lot always have plenty bandwidth for streaming your broadcast – plus more than. This additional headroom acts every bit a buffer to business relationship for any changes to your network. Any user activity on your network (e.grand., Internet uploads, VoIP communication, gaming) can affect both bandwidth and upload speed.
Use the elementary formula beneath to gauge the required bandwidth for streaming:
We recommend always having well-nigh 1.5x your stream's bitrate available to account for these possible network fluctuations. For instance, if your alive stream has a bitrate of 5,000 Kbps (5 Mbps), ensure you lot have at least 7.v Mbps total upload bandwidth available to provide a reliable alive stream. You may non need all of the calculated overhead bandwidth on a stable network, but it's always best to be on the safe side.
Consider your network and connectedness type
As we mentioned, there are many different types of Net connectivity, including fiber-optic, cable, satellite, and cellular data. Before alive streaming, consider the varying levels of available bandwidth and network reliability each choice offers.
For example, wireless cellular Internet tends to have lower maximum upload bandwidth and reliability, resulting in a lower-quality stream. Or maybe you live in a rural area and have a satellite connection. In that case, y'all might desire to take atmospheric condition into account before publishing your stream.
Fiber and cable connections generally offering higher speeds, which are best suited for alive streaming. For improved reliability, it's always all-time to use a hardwired Net connection over Wi-Fi or cellular.
Consider Isp upload speeds and information caps
Many ISPs advertise upload and download bandwidth in terms of maximum and minimum speed.
For example, an Internet package might be advertised equally "Upward to 10 Mbps up and 30 Mbps down". This item "upwards to" phrasing is used because Cyberspace speeds can vary. If using a cable network, for example, you're sharing the Internet with other cable users within a geographical surface area, so your bandwidth may slow during "peak" periods of Cyberspace activity during the twenty-four hour period.
Some ISPs too have bandwidth usage maximums – then exist aware your live stream doesn't go beyond your monthly upload cap, or you may be charged additional fees.
Running an Internet speed examination is also important. Y'all may take enough available bandwidth on your network but not plenty upload speed, depending on how many devices are sharing the network and the types of activities on those devices.
Ensure you take additional bandwidth if streaming multiple programs
Multi-streaming is an increasingly popular live streaming strategy that involves publishing your broadcast to more than 1 content distribution network (CDN) platform simultaneously. Multi-encoding, on the other hand, is a similar technique that involves streaming the same plan to the same CDN at different bitrates. Multi-streaming allows alive streams to reach a greater audience, while multi-encoding helps to ensure accessibility of your live stream to viewers of all levels of download bandwidth.
Keep in mind that each additional program you publish adds to your total outgoing bitrate and requires boosted upload bandwidth availability.
The terminal word
Equally you can see, the required bandwidth for streaming for a reliable live broadcast depends on a diversity of factors. While there is no "ane size fits all" configuration, rest assured that with the right tweaking you can publish a successful and reliable live stream regardless of your network.
And retrieve—equally a general rule of pollex, we recommend your streaming upload bandwidth be at least 1.5x the combined bit rate of all your streamed programs (when streaming in SD or above). Happy streaming!
