What is bandwidth?
Bandwidth is the capacity of a network to upload and download data. Internet bandwidth is the maximum volume of information you lot can send and receive in a measured amount of time. It's generally calculated in megabits per 2d (Mbps).
When streaming video to the Internet, you are consuming upload bandwidth. It's essential to know your network'due south available upload bandwidth because information technology enables (and also limits) the quality of your outgoing streams.
Available bandwidth depends on the network router, surroundings, and most importantly, the connection type. For case, punch-up Net had a maximum bandwidth of but 56 kilobits per second (Kbps). In contrast, more than modern connection types like fiber-optic landline (622 Mbps), Gigabit Ethernet (1,000 Mbps), and 4G LTE (100 Mbps) take much higher bandwidths.
Bandwidth vs. speed
Diverse online speed tests offer to test how fast your network is. Only is that the same as bandwidth? Not quite. "Bandwidth" and "speed" are oftentimes used interchangeably, yet in that location is a difference between these two 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 alive streaming involves uploading data to the Internet, having ample upload speed is important. In fact, for successful live streaming, you'll need both sufficient upload bandwidth and upload speed.
Solutions you tin stake your reputation on
Built for pro AV, Epiphan's rugged and reliable hardware encoders allow you capture, stream, and tape with confidence. Wherever your production teams accept them, Epiphan Cloud'due south configuration and monitoring streamline direction.
Equally with download speed, upload speed has a set up rate (e.g., "v Mbps upload speed") equally dictated past your Internet service provider (ISP). Considering bandwidth sets the upper limit for the information transfer rate, at that place'due south no sense in purchasing Cyberspace speeds from your Internet access provider that exceed your maximum bandwidth.
Bandwidth vs. bitrate
Because raw video and audio are too hefty to upload, streamed content needs to be encoded. Encoding compresses video and sound content into a size and format that's like shooting fish in a barrel to ship to the Net.
Bitrate is the amount of data encoded per unit of time. When it comes to streaming, information technology's commonly measured in Kbps, and less frequently in Mbps. Generally speaking, the college the bitrate, the higher the video quality, and the higher the upload bandwidth required.
To encode your content, you'll utilise either a software encoder or a hardware encoder (like Pearl Nano, Pearl Mini, or Pearl-2). Y'all volition set the bitrate in your encoder settings.
The total bitrate consists of the video and sound bitrates. The bitrate setting will depend on the video resolution and frame rate. For college resolutions and frame rates, you'll demand higher bitrate settings. For example, the recommended encoding settings for 4K streaming at 60 frames per 2d (fps) volition be higher than that for 1080p streaming at xxx fps. Insufficient bitrate volition cause your stream to appear inclement.
How much bandwidth do I need for alive streaming?
The amount of bandwidth you'll need depends on your encoding bitrate. For example, if you are encoding at 3,000 Kbps, yous will demand at least 3 Mbps of upload bandwidth. If your stream'south bitrate is too 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 five Mbps upload bandwidth limit.
Above are the 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 around 25 Mbps.
Different platforms (east.one thousand., YouTube, Twitch, Facebook) have different speed requirements and recommended encoding settings. And then be sure to double-bank check before streaming.
How to ensure you lot have enough bandwidth for streaming
Information technology's elementary math to realize that if you accept five Mbps of upload bandwidth, your stream bitrate should exist less than 5 Mbps. Simply merely how much less? Bandwidth limitations are merely office of the story! Yous'll need to consider some additional factors to ensure the success of your alive stream.
Always have some extra bandwidth (and upload speed) available
Ensure you e'er have enough bandwidth for streaming your broadcast – plus more than. This additional headroom acts equally a buffer to business relationship for any changes to your network. Whatsoever user activity on your network (due east.g., Internet uploads, VoIP communication, gaming) tin affect both bandwidth and upload speed.
Use the uncomplicated formula below to judge the required bandwidth for streaming:
We recommend always having nearly 1.5x your stream'due south bitrate available to business relationship for these possible network fluctuations. For instance, if your live stream has a bitrate of v,000 Kbps (five Mbps), ensure you accept at least 7.5 Mbps full upload bandwidth bachelor to provide a reliable live 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, at that place are many different types of Internet connectivity, including fiber-optic, cable, satellite, and cellular information. Before live streaming, consider the varying levels of available bandwidth and network reliability each choice offers.
For instance, wireless cellular Internet tends to have lower maximum upload bandwidth and reliability, resulting in a lower-quality stream. Or maybe you lot live in a rural area and have a satellite connection. In that case, yous might want to take weather into business relationship before publishing your stream.
Fiber and cable connections mostly offer higher speeds, which are all-time suited for alive streaming. For improved reliability, it's always all-time to utilize a hardwired Internet connectedness over Wi-Fi or cellular.
Consider Internet access provider upload speeds and data caps
Many ISPs annunciate upload and download bandwidth in terms of maximum and minimum speed.
For example, an Internet parcel might be advertised as "Up to ten Mbps up and 30 Mbps downwardly". This item "up to" phrasing is used because Internet speeds can vary. If using a cable network, for example, you're sharing the Internet with other cable users within a geographical surface area, and then your bandwidth may slow during "peak" periods of Internet activity during the day.
Some ISPs also accept bandwidth usage maximums – so be enlightened your live stream doesn't get beyond your monthly upload cap, or you may be charged additional fees.
Running an Internet speed test is also important. You may have enough available bandwidth on your network simply not enough upload speed, depending on how many devices are sharing the network and the types of activities on those devices.
Ensure you accept additional bandwidth if streaming multiple programs
Multi-streaming is an increasingly popular live streaming strategy that involves publishing your broadcast to more than one content distribution network (CDN) platform simultaneously. Multi-encoding, on the other hand, is a similar technique that involves streaming the aforementioned program to the same CDN at different bitrates. Multi-streaming allows live streams to attain 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 additional upload bandwidth availability.
The final word
As yous can meet, the required bandwidth for streaming for a reliable live broadcast depends on a variety of factors. While at that place 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 remember—as a general rule of pollex, we recommend your streaming upload bandwidth be at least i.5x the combined bit charge per unit of all your streamed programs (when streaming in SD or above). Happy streaming!
