What is bandwidth?
Bandwidth is the capacity of a network to upload and download data. Net bandwidth is the maximum volume of information you can send and receive in a measured amount of time. It'southward more often than not calculated in megabits per second (Mbps).
When streaming video to the Net, y'all are consuming upload bandwidth. It'due south essential to know your network's available upload bandwidth because it enables (and also limits) the quality of your approachable streams.
Available bandwidth depends on the network router, environment, and most importantly, the connectedness blazon. For case, dial-upward Internet had a maximum bandwidth of just 56 kilobits per 2nd (Kbps). In contrast, more modern connection types similar cobweb-optic landline (622 Mbps), Gigabit Ethernet (1,000 Mbps), and 4G LTE (100 Mbps) accept much college bandwidths.
Bandwidth vs. speed
Various online speed tests offer to exam how fast your network is. But 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 connection speed is as well measured in Mbps.
Since live streaming involves uploading data to the Internet, having aplenty upload speed is of import. In fact, for successful live streaming, you'll need both sufficient upload bandwidth and upload speed.
Solutions you can stake your reputation on
Built for pro AV, Epiphan's rugged and reliable hardware encoders permit you capture, stream, and record with confidence. Wherever your production teams take them, Epiphan Cloud'south configuration and monitoring streamline management.
Equally with download speed, upload speed has a set rate (e.one thousand., "5 Mbps upload speed") as dictated past your Isp (ISP). Considering bandwidth sets the upper limit for the data transfer rate, there's no sense in purchasing Internet speeds from your ISP that exceed your maximum bandwidth.
Bandwidth vs. bitrate
Because raw video and audio are too hefty to upload, streamed content needs to exist encoded. Encoding compresses video and audio content into a size and format that'south easy to send to the Internet.
Bitrate is the corporeality of information encoded per unit of time. When it comes to streaming, it's commonly measured in Kbps, and less frequently in Mbps. Mostly speaking, the higher the bitrate, the higher the video quality, and the higher the upload bandwidth required.
To encode your content, yous'll use either a software encoder or a hardware encoder (like Pearl Nano, Pearl Mini, or Pearl-ii). You will 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 rate. For higher resolutions and frame rates, you'll demand higher bitrate settings. For example, the recommended encoding settings for 4K streaming at 60 frames per 2nd (fps) will be higher than that for 1080p streaming at 30 fps. Bereft bitrate will crusade your stream to appear choppy.
How much bandwidth do I need for live streaming?
The corporeality of bandwidth you'll need depends on your encoding bitrate. For example, if yous are encoding at 3,000 Kbps, you will demand at least 3 Mbps of upload bandwidth. If your stream's bitrate is too high relative to your upload bandwidth, your live stream will exist unreliable for viewers. For case, a stream with a 6,000 Kbps bitrate doesn't work on a network with a 5 Mbps upload bandwidth limit.
To a higher place are the general required bandwidth for streaming guidelines. For example, the minimum bandwidth required for 1080p (Hard disk) streaming is 5 Mbps, while the minimum 4K (UHD) streaming bandwidth is around 25 Mbps.
Different platforms (e.g., YouTube, Twitch, Facebook) take different speed requirements and recommended encoding settings. And then be sure to double-check before streaming.
How to ensure you accept enough bandwidth for streaming
It'southward simple math to realize that if you accept 5 Mbps of upload bandwidth, your stream bitrate should be less than 5 Mbps. But simply how much less? Bandwidth limitations are only part of the story! You'll demand to consider some additional factors to ensure the success of your live stream.
Always take some extra bandwidth (and upload speed) available
Ensure you lot ever accept enough bandwidth for streaming your circulate – plus more. This boosted headroom acts as a buffer to business relationship for any changes to your network. Whatsoever user activity on your network (e.k., Internet uploads, VoIP communication, gaming) can touch on both bandwidth and upload speed.
Use the simple formula beneath to estimate the required bandwidth for streaming:
Nosotros recommend e'er having about 1.5x your stream'due south bitrate available to business relationship for these possible network fluctuations. For example, if your live stream has a bitrate of five,000 Kbps (5 Mbps), ensure you take at least seven.5 Mbps total upload bandwidth available to provide a reliable live stream. You may not need all of the calculated overhead bandwidth on a stable network, but information technology's always all-time to be on the safe side.
Consider your network and connection blazon
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 option offers.
For example, wireless cellular Internet tends to take lower maximum upload bandwidth and reliability, resulting in a lower-quality stream. Or possibly you live in a rural area and accept a satellite connection. In that example, you might want to take conditions into account before publishing your stream.
Cobweb and cable connections generally offer college speeds, which are best suited for live streaming. For improved reliability, information technology'south always all-time to use a hardwired Internet connectedness over Wi-Fi or cellular.
Consider Isp upload speeds and data caps
Many ISPs annunciate upload and download bandwidth in terms of maximum and minimum speed.
For case, an Internet package might exist advertised as "Up to 10 Mbps upwardly and xxx Mbps down". This particular "upward to" phrasing is used because Internet speeds can vary. If using a cable network, for instance, you're sharing the Cyberspace with other cablevision users within a geographical area, so your bandwidth may tiresome during "peak" periods of Cyberspace action during the solar day.
Some ISPs also have bandwidth usage maximums – so be aware your alive stream doesn't go beyond your monthly upload cap, or yous may exist charged additional fees.
Running an Internet speed examination is besides important. You lot may have enough available bandwidth on your network but not enough upload speed, depending on how many devices are sharing the network and the types of activities on those devices.
Ensure you have additional bandwidth if streaming multiple programs
Multi-streaming is an increasingly pop alive streaming strategy that involves publishing your circulate to more than one content distribution network (CDN) platform simultaneously. Multi-encoding, on the other mitt, is a similar technique that involves streaming the same programme to the aforementioned CDN at different bitrates. Multi-streaming allows live streams to accomplish a greater audience, while multi-encoding helps to ensure accessibility of your alive stream to viewers of all levels of download bandwidth.
Keep in listen that each additional program you publish adds to your total outgoing bitrate and requires additional upload bandwidth availability.
The final word
As you can see, the required bandwidth for streaming for a reliable live broadcast depends on a variety of factors. While there is no "one 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 exist at least 1.5x the combined bit charge per unit of all your streamed programs (when streaming in SD or above). Happy streaming!
