# Rtmp bandwidth calculator

Use this calculator to estimate the bandwidth needs or actual data usage of a website. Be sure to include the bot traffic Google bots, Bing bots, etc as well as other connection needs. Often the bots use more bandwidth than real users. Bandwidth is a term that has different meanings within different contexts. In terms of computing, bandwidth is defined as the bit-rate of available or consumed information and is typically expressed in units of bits per second along with its metric multiples.

Even within computing, bandwidth can be differentiated between network bandwidth, data bandwidth, and digital bandwidth.

However, one of the most common ways in which the term bandwidth is used relates to the internet, as "the volume of information per unit of time that a transmission medium [channel] can handle. Due to factors such as protocols and encryption, such as transmission control protocol TCPwhich is largely used in internet traffic, a channel stated to have a bandwidth of X bits per second may not actually transmit data at X rate.

In information technology, a bit is the smallest unit of information. It can hold only one of two values—0 or 1. A byte is a unit that consists of 8 bits. A byte can represent values from 0 to The bit is the unit of data transfer, meaning that a communications device or system with a bandwidth of 8 MB has a transfer rate of 8 Mega bits per second, which is equivalent to 1 Mega byte per second.

In relation, the unit of information storage is the byte. In terms of memory or a hard disk, 8GB of capacity would mean that 8 Giga bytes of information could be stored, which is equivalent to 64 Giga bits. The amount of bandwidth a person or company needs is entirely dependent on how they plan to use the Internet. Streaming or hosting large amounts of video for example, requires far more bandwidth than simply browsing the Internet.

The above calculators can be used to make estimation based on potential needs. Financial Fitness and Health Math Other.RTMP is mostly depreciated for use as a viewer-facing video streaming protocol. However, RTMP is the most commonly used streaming protocol. On an unreliable wireless network, HLS allows the player to use a lower quality video, thus reducing bandwidth usage. HLS videos can be made highly available by providing multiple servers for the same video, allowing the player to swap seamlessly if one of the servers fails.

One of the parameter is having HLS segment time lower value which is by default 2 sec and you can decrease this value to have lower latency but then players start to poll server more frequently and it can be waste of resource usage.

Second critical parameter is sending key frame in every 2 seconds This value should consistent with HLS segment time and it is critical to split videos into 2 sec duration segments. Open Broadcaster Software OBS generally sends key frame for every 10 seconds and the latency will increase to 30 sec because player needs 3 segments to start to play.

After you have done these adjustments, your delay will be significantly reduced. Each frame of a volumetric video sequence is more different than traditional video frames. As we mentioned before, generally, each frame contains one Read more….

What is bandwidth? - All you need to know

So how much streaming upload bandwidth do you actually need to ensure a successful live broadcast? The answer is… it depends! Understanding factors such as stream quality, encoding settingsand other conditions are essential to configuring a worry-free and reliable live broadcast.

Streamed content needs to be encoded. Video and to a lesser extent, audio content that is not compressed consumes far too much upload bandwidth to support a reliable broadcast for viewers. The goal of encoding is to digitize and compress your video and audio content to a bandwidth-friendly file size without sacrificing quality.

Higher bit rates generally translate into higher quality video and audio. Naturally, the required network bandwidth for 4K streaming will be higher than that for p streaming. While the list below is intended for Netflix viewers so viewers can confirm they have the required download speed to watch a streamyou can nonetheless use the information provided as a ballpark estimate of the bit rates required for each popular resolution.

Note: these values are simply recommendations—they are not necessarily industry standard! Above are the general required bandwidth for streaming guidelines. For example, the minimum required upload bandwidth for p streaming is 5 Mbps, while the minimum 4K streaming bandwidth is around 25 Mbps. But just how much less? Bandwidth limit is only part of the story!

Ensure you always have enough bandwidth for streaming your broadcast—plus more. Upload bandwidth can be affected by all forms of user activity on your network, such as Internet uploads, VOiP communication, or gaming.

Non-necessary Non-necessary.In fact, there is a subtle difference between them. Bandwidth : the maximum amount of data that can be transmitted over an Internet connection, as measured in Megabits per second Mbps. Speed : the rate at which data can be downloaded or uploaded to a given device using that Internet connection, also measured in Megabits per second. Think of it this way: data is traveling over the Internet cable like water in a pipe.

Bandwidth is the width of that pipe — essentially, the maximum volume of water data that can pass through at once. Speed, meanwhile, is the amount of Megabits per second that can be downloaded by a given device using your home network.

### Bandwidth for streaming: how much do I need?

Megabits per second Mbps is the most common measurement of consumer-grade Internet connections. Internet plans can be anywhere from 1 Mbps all the way up 1, Mbps or more. Anything above 25 Mbps is considered usable for modern applications.

Speeds below Mbps can be challenging for a large household. Use the tool above to calculate what speed range you should be looking for when shopping for Internet service. When you visit a website, all the data you see has to travel from a remote server to your computer.

The amount of time it takes the request for that data to leave your home, reach the server, and start returning data is called latency. You can think of latency as the issue you get on a long-distance phone call. The amount of speed or bandwidth you need will vary widely depending on the size of your household, number of users, intended activities, and etc. The best way to find out exactly how much bandwidth you need to subscribe to is to enter your household details into the bandwidth calculator tool at the top of this page.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am assigned on project to live broadcast an event on the internet which may have 50, user s.

This will be a broadcast so all users will see same live video. My query is what would be my bandwidth requirement in terms of no of users viewing that stream. If i would install a server with streaming capability having Bandwidth of 50Mbps would it be enough considering it is a broadcast. Is is possible to achieve this through RTSP. How do services like Google Hangout air work? What protocol is used in Hangout and Youtube when live broadcasts are done.

To calculate how much bandwidth you need, you will need to know your average bitrate for the video. Let's just say that your live video's bitrate is 1 megabit ignoring overhead, retransmissions, sequences that require more bandwidth, etc. Your 50Mbps only covers 50 users. That's 0. You need 1, of those connections, to barely handle the load. If you actually have a live event that 50, people will see, you no doubt have sponsors and should be able to afford a proper CDN.

This isn't something you host yourself. You pay for a CDN so that capacity is available as you need it, and servers are close to your audience.

The best thing to do would be to get a YouTube account with live streaming, and let YouTube pay for the bandwidth. Now, the protocol you use has nothing to do with what size of IP block you have. Those are unrelated, separate issues. You pick a streaming protocol based on device compatibility and capability. When you stream them to YouTube, there is a massive CDN that handles distribution in multiple codecs, multiple protocols, and multiple points of presence.
