Specifically, how fast does your Internet upload speed have to be in order to live stream Truthfully, theres no hard or fast rule that answers this question. The answer depends on a wide variety of variables. Dont worry, thats why were here Lets take a look at these variables at play so that you can make a final decision about the bandwidth you need for your live streaming purposes. Understanding Internet Speed Upload and Download. When it comes to measuring the speed of an Internet connection, two things matter download speed and upload speed.

Download speed is a measure of how fast data from the Internet can enter your network. You can think of it like a tube the bigger the tube, the faster information can flow through it into your network. Upload speed, on the other hand, is a measure of how quickly you can send data from inside your network out to other computers or servers. Both download and upload speed are usually measured using Kbps kilobits per second or Mbps megabits per second. For live streaming, both download and upload speed are important. Upload speed is what determines how much data a broadcaster can send out as a live video feed. The faster the upload speed, the higher the video quality can be while broadcasting. Download speeds are important for viewers, rather than broadcasters. A slow download speed means that live streams may buffer or lag. Warning Uploads are Slower than Download Its important to know that most Internet connections have upload speeds that are only a fraction of their download speed. It wont matter if you have a lighting fast download speed if your upload speed is too slow for your live stream. You should also be aware that most Internet connections advertise speeds up to a certain number. This is a peak measure and often means that sustained speeds are 2. Despite enabling you to watch live streams, these lower than advertised speeds may mean your connection is inadequate for actually live streaming. What Are the Bandwidth Requirements for Streaming Live Video The biggest single factor impacting your bandwidth requirements is broadcast quality. Streaming video at a resolution of 3. On the other hand, sending a video file with full high definition resolution takes a great deal more. High definition video files have up to 1. SD video, and can incorporate higher quality audio files as well. As the world begins to move towards 4. K video, bandwidth requirements for streaming will face greater increases. Another element that increases the size of video files is the frame rate. Frame rate refers to how many still images make up one second of video. Online, almost all video is encoded at 3. However, sports and video game streams are often encoded at 6. Video at 6. 0 fps is approximately twice the size of 3. Codecs and Bit Rates. To understand the specific bandwidth requirements of a stream, you need to understand the basics of video encoding. Encoding is mostly about compression. Its a way of taking video files and making them smaller so they can be transmitted more easily over the Internet. For live streaming, the H. H. 2. 64 produces small file sizes, and the resulting video can be played on just about any device. No matter the codec used, quality primarily depends on the bit rate the file is encoded at. This is essentially the amount of data thats contained within one second of video, measured using Kbps or Mbps. Comparing Video Bit Rate and Internet Upload Speed. The bit rate of your video stream will inform the upload bandwidth you need. For example, if your outbound video stream is being streamed at a bit rate of 5. Kbps, then your Internet upload speed will need to be at least 5. Kbps. In reality though, Internet upload speeds fluctuate second to second. Connections drop, reconnect, and experience other speed bumps. Generally this means that to stream a video, you want your Internet upload speed to be at least double the bit rate of the video you plan to broadcast. Single vs. Multiple Bit Rate. Most live streams require multiple bit rates for video to be streamed at the same time. This enables viewers to watch on both mobiles on the coffee shop Wi. Fi network and Roku boxes connected to high speed cable internet. In essence, viewers with slow Internet speeds will automatically switch to low bit rate streams, and viewers with fast Internet will receive the higher quality streams. This method provides a much better experience for viewers, and should be considered a standard practice. However, it does complicate things for broadcasters. Instead of broadcasting a single live stream, broadcasters now have to stream multiple different feeds simultaneously to accommodate different Internet speeds. Modern live broadcasting formats like MPEG DASH, HLS, HDS, and Microsoft Smooth Streaming use a process called adaptive bit rate streaming to automatically shift viewers to the best available stream. Multi Bit Rate Streaming. Streaming a variety of different bit rates at the same time can be somewhat tricky. It requires more processing power and more upload speed. In terms of upload speed, all the bit rates youre uploading add together to determine how much bandwidth you need overall. If you want quality 4. K video, that tends to use at least 1. Mbps. So in order to get a stable 4. K stream going, youll need to double that for an upload speed of 3. Mbps. Needless to say, thats a great deal of upload speed. In terms of processing power, more streams require more power. However, any powerful laptop computer should be able to handle encoding multiple streams. In a production environment or a situation where failure isnt an option, you may want to consider a hardware encoder such as those produced by Teradek, Matrox or Niagara. These powerful, portable devices are capable of crunching plenty of data at once to ensure that these streams continue as smoothly as possible. A Note on Codecs and Bit Rate. Codecs and bit rates operate independently, but only between different codecs. For example, an H. Mbps is going to have better quality than one encoded at 1 Mbps. However, an H. 2. Mbps may actually be better than the 2 Mbps H. Similarly, other video factors can change independently of bit rate. For example, frame size is unrelated to codec and only partially related to bit rate. Videos with different frame sizes can be encoded using H. However, videos with larger frame sizes will spread out the data across a larger frame. This can lead to a perceived lower quality. Meanwhile, a low resolution video with a high bit rate can appear visually excellent, even though it is small. Single Format or Multiple In the past, the standard for streaming video over the Internet used the Macromedia now Adobe flash standard. However, times have changed. While flash video is still widely used on desktop computers, its not supported on many mobile devices. With the popularity of smartphones and tablets, broadcasters should be making mobile users a priority. Most notably, i. OS i. Download Crack For Fruity Loops 10 Crack there. Phones and i. Pads doesnt support flash video. Some old versions of the Android mobile operating system do support flash, but its being phased out rapidly. This means you will either want to stream only in a modern format like HLS which can be played by most flash video players, or use multiple formats.
