What is bandwidth?
Bandwidth is the capacity of a network to upload and download data. Net bandwidth is the maximum volume of data you can send and receive in a measured corporeality of time. It's generally calculated in megabits per second (Mbps).
When streaming video to the Cyberspace, you are consuming upload bandwidth. It's essential to know your network'due south available upload bandwidth because it enables (and as well limits) the quality of your outgoing streams.
Available bandwidth depends on the network router, environment, and virtually importantly, the connexion type. For example, dial-upwardly Internet had a maximum bandwidth of just 56 kilobits per 2d (Kbps). In contrast, more modern connection types similar cobweb-optic landline (622 Mbps), Gigabit Ethernet (1,000 Mbps), and 4G LTE (100 Mbps) have much college bandwidths.
Bandwidth vs. speed
Various online speed tests offer to exam how fast your network is. Simply is that the same as bandwidth? Not quite. "Bandwidth" and "speed" are often used interchangeably, nonetheless there is a difference between these two terms.
If bandwidth is the maximum rate for information transfer, speed is how fast information is factually downloaded or uploaded. Like bandwidth, the connection speed is as well measured in Mbps.
Since live streaming involves uploading data to the Internet, having aplenty upload speed is important. In fact, for successful alive streaming, yous'll need both sufficient upload bandwidth and upload speed.
Solutions you tin can stake your reputation on
Built for pro AV, Epiphan'due south rugged and reliable hardware encoders allow you capture, stream, and record with conviction. Wherever your production teams take them, Epiphan Cloud'due south configuration and monitoring streamline direction.
As with download speed, upload speed has a set up rate (e.g., "5 Mbps upload speed") as dictated by your Internet access provider (Internet service provider). Considering bandwidth sets the upper limit for the data transfer charge per unit, there's no sense in purchasing Internet speeds from your Internet service provider that exceed your maximum bandwidth.
Bandwidth vs. bitrate
Considering raw video and audio are too hefty to upload, streamed content needs to be encoded. Encoding compresses video and audio content into a size and format that's like shooting fish in a barrel to ship to the Internet.
Bitrate is the amount of data encoded per unit of fourth dimension. When it comes to streaming, it's usually measured in Kbps, and less ofttimes in Mbps. Generally speaking, the higher the bitrate, the higher the video quality, and the higher the upload bandwidth required.
To encode your content, you lot'll utilise either a software encoder or a hardware encoder (like Pearl Nano, Pearl Mini, or Pearl-two). You will ready 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 rate. For college resolutions and frame rates, you lot'll need higher bitrate settings. For example, the recommended encoding settings for 4K streaming at 60 frames per 2d (fps) will exist higher than that for 1080p streaming at 30 fps. Bereft bitrate will cause your stream to appear 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 are encoding at iii,000 Kbps, yous will demand at least 3 Mbps of upload bandwidth. If your stream's bitrate is also high relative to your upload bandwidth, your live stream will be unreliable for viewers. For instance, a stream with a 6,000 Kbps bitrate doesn't 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 five Mbps, while the minimum 4K (UHD) streaming bandwidth is around 25 Mbps.
Dissimilar platforms (due east.one thousand., YouTube, Twitch, Facebook) have different speed requirements and recommended encoding settings. So be sure to double-check earlier streaming.
How to ensure you lot have enough bandwidth for streaming
It's simple math to realize that if you have 5 Mbps of upload bandwidth, your stream bitrate should be less than 5 Mbps. But just how much less? Bandwidth limitations are simply part of the story! You'll need to consider some additional factors to ensure the success of your live stream.
E'er have some actress bandwidth (and upload speed) available
Ensure you e'er have enough bandwidth for streaming your broadcast – plus more. This additional headroom acts as a buffer to business relationship for whatsoever changes to your network. Any user activity on your network (due east.grand., Internet uploads, VoIP communication, gaming) tin can affect both bandwidth and upload speed.
Employ the simple formula below to estimate the required bandwidth for streaming:
We recommend always having nigh 1.5x your stream's bitrate available to account for these possible network fluctuations. For example, if your live stream has a bitrate of 5,000 Kbps (5 Mbps), ensure y'all have at to the lowest degree seven.v Mbps total upload bandwidth available to provide a reliable live stream. You may not demand all of the calculated overhead bandwidth on a stable network, merely it'southward always best to exist on the rubber side.
Consider your network and connection type
As we mentioned, at that place are many different types of Cyberspace connectivity, including cobweb-optic, cable, satellite, and cellular information. Before alive streaming, consider the varying levels of bachelor bandwidth and network reliability each option offers.
For example, wireless cellular Net tends to have lower maximum upload bandwidth and reliability, resulting in a lower-quality stream. Or maybe you alive in a rural area and have a satellite connectedness. In that case, you might desire to take weather into account before publishing your stream.
Fiber and cable connections generally offering higher speeds, which are best suited for live streaming. For improved reliability, it's ever all-time to use a hardwired Cyberspace connexion 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 "Up to 10 Mbps upwardly and xxx Mbps downward". This particular "upward to" phrasing is used because Cyberspace speeds tin can vary. If using a cable network, for case, yous're sharing the Internet with other cable users inside a geographical area, and so your bandwidth may deadening during "acme" periods of Internet activeness during the day.
Some ISPs also have bandwidth usage maximums – so be aware your live stream doesn't go across your monthly upload cap, or you may exist charged additional fees.
Running an Internet speed test is as well of import. Yous may have enough available bandwidth on your network but non enough upload speed, depending on how many devices are sharing the network and the types of activities on those devices.
Ensure you lot have boosted 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 mitt, is a similar technique that involves streaming the aforementioned program to the same CDN at dissimilar bitrates. Multi-streaming allows live streams to reach a greater audience, while multi-encoding helps to ensure accessibility of your alive stream to viewers of all levels of download bandwidth.
Keep in mind that each additional program you publish adds to your full approachable bitrate and requires additional upload bandwidth availability.
The final give-and-take
Equally you can run into, the required bandwidth for streaming for a reliable live broadcast depends on a diverseness 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 recollect—as a general dominion of thumb, we recommend your streaming upload bandwidth be at to the lowest degree 1.5x the combined bit rate of all your streamed programs (when streaming in SD or above). Happy streaming!
