Do you want to live stream or broadcast your video content to a wide audience? There are a few technical options for streaming protocols that you’ll want to consider to achieve a high-quality viewing experience for your viewers. In this article we’ll explore six of the most preferred and widely used video streaming protocols for professional broadcasting and help you determine what is most suitable for your business and audience. Get ready to go behind the scenes of how live and on-demand video streaming works.
A video streaming protocol is the technology that enables video content to be delivered over the internet. The protocol determines how the video file is broken up into packets for transmission and reassembled for playback.
Choosing the right video streaming protocol for your needs depends on your delivery requirements, playback environments, and infrastructure. The options have expanded, but interoperability remains key.
When it comes to streaming video, it’s easy to get confused by all the terminology. Streaming protocol, codec, container format – what’s the difference? Simply put:
The streaming protocol you choose depends on your streaming platform and playback devices. Codecs determine video quality and compression. And container formats organize everything into a single file.
So don’t stress the semantics. Focus on delivering an amazing viewing experience for your audience. The right streaming technology and video infrastructure, like that offered by ViewLift, can handle the rest.
When it comes to professional video streaming, certain protocols are preferred for delivering high quality live and on-demand video to audiences. Here are six of the top protocols used:·
HTTP Live Streaming (HLS) is an adaptive bitrate streaming protocol developed by Apple. It’s great for delivering live and on-demand video content to iOS and Apple TV devices.
HLS works by chopping up your video into small segments (usually 10 seconds) and multiple bitrates. It stores these segments in an M3U8 manifest file which tells the video player which segments to download based on the viewer’s internet speed and device. This allows for an uninterrupted viewing experience.
ViewLift’s video streaming platform makes it easy to deliver your live and on-demand video with HLS. We take care of the encoding, packaging and delivery so you can focus on creating amazing content. Our powerful analytics give you insight into viewer engagement so you can optimize your video strategy.
RTMP is a popular video streaming protocol used by many professional broadcasters. It allows you to stream live video to viewers over the internet in real time. RTMP works by pushing your video stream to a streaming server, which then distributes it to your viewers.
To use RTMP, you’ll need an encoder to capture and encode your video, streaming server software to distribute your stream, and a player for your viewers to watch the stream. Many streaming media servers like Wowza, Nginx, and Red5 support RTMP ingestion and playback. You’ll also want a high-speed internet connection to push your stream without buffering.
RTMP is a solid, time-tested choice for professional streaming at scale. However, it does require more technical expertise to set up and maintain your own streaming infrastructure. If you want an easy, customizable way to launch your own streaming channel without the hassle of managing servers and encoders, consider a streaming platform like ViewLift. We handle all the complexity of video streaming so you can focus on creating great content.
WebRTC is an open-source protocol for browser-based Real-Time Communications (RTC). It allows voice calling, video chatting, and P2P file sharing directly in the browser without the need for browser plugins.
WebRTC lets you add real-time communication capabilities to your site or web/native application without having to implement the intricacies of signaling, media routing, and codec handling yourself. All you have to do is add a few lines of JavaScript to your web app, and you’ll have a full RTC stack running in the browser.
WebRTC continues to gain popularity for embedding real-time voice, video, and data sharing capabilities in web and native apps. With its simplicity, performance, and wide browser support, WebRTC is the ideal choice for adding interactive media streaming features to your applications.
Secure Reliable Transport (SRT) is an open source video transport protocol that optimizes streaming performance across unreliable networks.
SRT uses packet loss recovery and retransmission techniques to ensure reliable video delivery over unpredictable networks like the public Internet. It adapts to the network conditions by monitoring latency and packet loss, then adjusting video transmission rates accordingly. This results in a smooth streaming experience for your viewers even with high packet loss and fluctuating bandwidth.
SRT also provides encryption and authentication for secure streaming. It uses AES-128/256 cipher encryption to protect your streams from unauthorized access and tampering. SRT additionally supports authentication via a shared secret key to verify the sender and receiver.
The Real-Time Streaming Protocol (RTSP) is a network control protocol designed for use in entertainment and communications systems to control streaming media servers.
RTSP allows a client to remotely control a streaming media server, issuing VCR-like commands such as play, record and pause, and allowing time-based access to files on a server.
RTSP works with both live and on-demand data and can use either UDP or TCP as a transport protocol. Most often, RTSP uses RTP for media stream delivery, but it can also use other protocols.
Some of the most well-known uses of RTSP are in IP cameras for video surveillance and in platforms for live streaming and video on demand. RTSP remains an important protocol for transmitting live and on-demand streaming media on IP networks.
Dynamic Adaptive Streaming over HTTP (MPEG-DASH) is an adaptive bitrate streaming technique that detects your viewer’s bandwidth and CPU capacity in real time and adjusts video quality accordingly. MPEG-DASH streaming helps ensure a high-quality experience for your audience.
With MPEG-DASH, your video is encoded at multiple bitrates, then chopped into segments that can be dynamically reassembled based on each viewer’s internet connection speed and device capabilities. So someone on a fast network or premium device may get higher resolution, while someone with a slower connection gets a lower resolution that still plays smoothly.
MPEG-DASH is supported on many platforms and devices, including desktop and mobile browsers, media players, Smart TVs, and streaming media devices. Launching with MPEG-DASH means your content can reach the widest possible audience with an optimized viewing experience every time.
If building your own video streaming platform sounds complicated, consider a turnkey OTT video streaming solution. A complete OTT platform handles encoding, hosting, and delivering your content using MPEG-DASH so you can focus on creating great content for your viewers. With the right partner, getting started with MPEG-DASH streaming and launching your own OTT channel can be fast and affordable.
In the end, consider your priorities and technical requirements. The right protocol for a live e-sports stream may differ from a corporate all-hands meeting. Do some tests and choose what works best for your particular use case. The options are out there—you just have to streamline them.
YouTube is the most popular video streaming platform, so it makes sense to optimize your live streams for playback on YouTube. YouTube supports several streaming protocols to deliver your live video to viewers with the best quality and lowest latency.
The Real-Time Messaging Protocol (RTMP) is the standard for streaming live video to YouTube. With RTMP, you can stream high-definition video with low latency. Most encoders and streaming software support RTMP streaming to YouTube.
While streaming protocols may seem complex, choosing the right formats for your needs is key to success. Focus on:
By assessing your needs, priorities and resources, you can determine the ideal streaming formats for your project. With the options available, there’s a solution for every use case. The key is starting with the basics, then building from there.
