![]() However, container format isn’t as central a concept for live streamers. In essence, a container format functions like a “box” that usually contains a video file, an audio file, and metadata. In many cases, format simply refers to the container format of a video file. ![]() H.264, the most common video codec, is widely used for online video.Īs with codec, the term “format” can also be confusing in the context of video streaming protocols. For example, Apple ProRes is often used for video editing. Logically, different streaming codecs are used for different purposes. Simply put, the term “codec” refers to video compression technology. Protocols, codecs, and container formats are separate facets of streaming.Īmong others, one common source of confusion in the realm of streaming video relates to the difference between a video protocol and a codec. Some video protocols only work on certain systems, and other video protocols focus on digital rights management ( DRM).Īs we move through some specific video streaming protocols, we will put these and other characteristics into perspective. Some protocols focus on reducing latency, or the delay between an event happening in real life and when it plays on the viewer’s screen. So if a viewer has a slow internet speed, they will be delivered a lower-quality video, and if a viewer has a faster internet speed, they will be delivered a higher-quality video. This technology will deliver the best quality that a viewer can support at any given time. Many are “ adaptive bitrate” protocols, for example. Streaming protocols can get much more complex. That is a basic explanation of how streaming protocols work. Otherwise, it’s coming from a file for video-on-demand VOD content. If you’re streaming live video, the source video comes in straight from a camera. These chunks then arrive sequentially and playback as they’re received. This involves breaking the video up into small chunks. Most video files aren’t designed for streaming, which means streaming a video involves first converting it into a streamable file. ![]() This leads to two major considerations, namely small file size and universal playback. Most digital video is designed for two things: storage and playback. Please note that this post has been updated to reflect the latest developments in video streaming protocols as of July 2023.Ī video streaming protocol is necessary for live broadcasting.Ī video streaming protocol is a standardized delivery method for breaking up a video into chunks, sending it to the viewer, and reassembling it. Video streaming protocols are the rules and methods that are used to break video files into small pieces so that they can be delivered to your viewers.īefore we go further, let’s look a little further into the “why” behind video streaming protocols. ![]() Finally, we’ll enlighten you with relevant background information so that you can better understand the relationship between a codec vs. Furthermore, we’ll shed light on and break down all the acronyms associated with video streaming protocols. We’ll cover what they do and when they should be used. In this article, we’re going to identify and discuss the most common video streaming protocols. In streaming, this amounts to the transference of video files to and from your encoder, streaming host and the video player your audience views. Essentially, these protocols are technical processes that facilitate the efficient transfer of data from one program to another. These generally refer to different video streaming protocols. There are many different acronyms used in live streaming. How to Choose Video Protocols for Your Stream.Dynamic Adaptive Streaming over HTTP (MPEG-DASH) 6 Preferred Protocols for Video Streaming.
