What is bandwidth?
Bandwidth is the capacity of a network to upload and download information. Internet bandwidth is the maximum volume of information y'all can transport and receive in a measured amount of time. It'south generally 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'due south available upload bandwidth because it enables (and besides limits) the quality of your outgoing streams.
Available bandwidth depends on the network router, surroundings, and most chiefly, the connection type. For example, dial-upwardly Cyberspace had a maximum bandwidth of just 56 kilobits per 2nd (Kbps). In contrast, more modernistic connection types like fiber-optic landline (622 Mbps), Gigabit Ethernet (i,000 Mbps), and 4G LTE (100 Mbps) take much higher bandwidths.
Bandwidth vs. speed
Diverse online speed tests offer to examination how fast your network is. But is that the same as bandwidth? Not quite. "Bandwidth" and "speed" are frequently used interchangeably, nevertheless in that location is a difference between these two terms.
If bandwidth is the maximum charge per unit for data transfer, speed is how fast data is factually downloaded or uploaded. Like bandwidth, the connection speed is also measured in Mbps.
Since live streaming involves uploading data to the Internet, having aplenty upload speed is of import. In fact, for successful alive streaming, y'all'll need both sufficient upload bandwidth and upload speed.
Solutions you tin pale your reputation on
Built for pro AV, Epiphan'south rugged and reliable hardware encoders permit yous capture, stream, and record with confidence. Wherever your production teams have them, Epiphan Cloud'southward configuration and monitoring streamline management.
As with download speed, upload speed has a ready rate (due east.thousand., "v Mbps upload speed") every bit dictated by your Internet access provider (Internet service provider). Because bandwidth sets the upper limit for the data transfer charge per unit, there'due south no sense in purchasing Internet speeds from your Isp that exceed your maximum bandwidth.
Bandwidth vs. bitrate
Considering raw video and sound are too hefty to upload, streamed content needs to be encoded. Encoding compresses video and audio content into a size and format that'due south easy to ship to the Cyberspace.
Bitrate is the amount of information encoded per unit of time. When information technology comes to streaming, it's ordinarily measured in Kbps, and less frequently 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'll use either a software encoder or a hardware encoder (similar Pearl Nano, Pearl Mini, or Pearl-2). Yous 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 college resolutions and frame rates, y'all'll need higher bitrate settings. For example, 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 appear choppy.
How much bandwidth exercise I need for live streaming?
The amount of bandwidth you'll need depends on your encoding bitrate. For example, if you are encoding at three,000 Kbps, yous will need at least 3 Mbps of upload bandwidth. If your stream's bitrate is too loftier relative to your upload bandwidth, your alive stream volition be unreliable for viewers. For example, a stream with a 6,000 Kbps bitrate doesn't work on a network with a 5 Mbps upload bandwidth limit.
Above are the full general required bandwidth for streaming guidelines. For case, 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.m., YouTube, Twitch, Facebook) take different speed requirements and recommended encoding settings. And so be sure to double-check before streaming.
How to ensure yous have enough bandwidth for streaming
It's uncomplicated math to realize that if you have v Mbps of upload bandwidth, your stream bitrate should be less than five Mbps. Only just how much less? Bandwidth limitations are only role of the story! You'll demand to consider some additional factors to ensure the success of your live stream.
Always have some extra bandwidth (and upload speed) available
Ensure you ever have enough bandwidth for streaming your broadcast – plus more. This additional headroom acts as a buffer to business relationship for any changes to your network. Whatever user activity on your network (e.g., Internet uploads, VoIP communication, gaming) tin impact both bandwidth and upload speed.
Utilise the simple formula below to judge the required bandwidth for streaming:
We recommend always having nearly 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 accept at least vii.v Mbps total upload bandwidth bachelor to provide a reliable alive stream. You may not 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 connection type
As we mentioned, there are many different types of Net connectivity, including fiber-optic, cable, satellite, and cellular data. Earlier alive streaming, consider the varying levels of available bandwidth and network reliability each choice offers.
For example, wireless cellular Net tends to take lower maximum upload bandwidth and reliability, resulting in a lower-quality stream. Or maybe you lot alive in a rural area and take a satellite connexion. In that case, you might want to take weather into account before publishing your stream.
Cobweb and cablevision connections generally offer higher speeds, which are best suited for live streaming. For improved reliability, it'southward always best to employ a hardwired Net connection over Wi-Fi or cellular.
Consider ISP upload speeds and data caps
Many ISPs advertise upload and download bandwidth in terms of maximum and minimum speed.
For example, an Net parcel might be advertised as "Upward to ten Mbps up and 30 Mbps down". This particular "upwards to" phrasing is used because Internet speeds can vary. If using a cablevision network, for example, you lot're sharing the Internet with other cable users inside a geographical surface area, and so your bandwidth may tiresome during "peak" periods of Internet activity during the day.
Some ISPs as well have bandwidth usage maximums – so be aware your live stream doesn't get beyond your monthly upload cap, or yous may be charged boosted fees.
Running an Internet speed test is too important. Yous 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 take additional bandwidth if streaming multiple programs
Multi-streaming is an increasingly pop live streaming strategy that involves publishing your circulate 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 aforementioned CDN at different bitrates. Multi-streaming allows alive streams to reach a greater audition, 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 plan you publish adds to your total outgoing bitrate and requires additional upload bandwidth availability.
The final word
Every bit y'all can see, the required bandwidth for streaming for a reliable alive circulate depends on a diverseness of factors. While in that location is no "one size fits all" configuration, residuum assured that with the right tweaking you tin publish a successful and reliable live stream regardless of your network.
And retrieve—as a general rule of pollex, nosotros recommend your streaming upload bandwidth be at least i.5x the combined scrap rate of all your streamed programs (when streaming in SD or above). Happy streaming!
