Simulcasting, is a short form for the simultaneous broadcasting. This is a process of broadcasting the same media content through multiple distribution channels simultaneously
The concept includes streaming the same content across various digital platforms including social media websites, homepage, apps and media sites such as youtube, facebook, linkedIn, Vimeo etc
Previously Simulcating was used in traditional broadcasting to transmit signals in different frequencies and media types
For example in radio transmitting over different frequencies to reach a wider audience or in television transmitting on different TV channels to reach a wider audience
How does Simulcast work?
1. Content Creation
The first step is the content creation, where the content that is tobe simulcasted is created. This content includes video streams, audio streams and live events etc
2. Encoding
Once the content is created then the content is encoded, so that it can be transmitted over the internet through different channels. This includes video compression and other converting media into different streaming protocols that are supported
The content is encoded in different formats that are supported by different social media and distribution networks.
3. Distribution
Once the encoding is done the content is distribution through various social media and content distribution sites. These websites use their own content distribution technologies such as CDNs to distribute the content all across the world
CDN are servers that are located all across the world so that the are nearest to the user who is requesting the content
4. Streaming Protocols
There are different streaming protocols that are in use by different distribution channels.
These protocols include HLS that is the HTTP Live Streaming and the MPEG-DASH Dynamic Adaptive Streaming over HTTP are popular
These protocols have features like delivering the content in chunks and played over time this helps smoothen out the video over intermittent internet connection
RTMP or Real Time Streaming Protocol is mostly used for high quality streams with low latency such as sports
5. BroadCasting to Multiple Platforms
As we have already discussed the streams are broadcasted to multiple channels. These channels might include streaming services, social media platforms like youtube, facebook, twitter etc and media channels
6. monitoring and analysis
When you are simulcasting, it is essential to check the streams performance and analytics to check whether the stream is working properly on all platforms or not
It is also important to check viewer engagement and other metrics on different streaming platforms
Benefits of Simulcasting
There are many benefits of Simulcasting for businesses and content creators and broadcasters
These entities can maximize their reach with simulcasting
1. Expanded audience Reach
Geographic expansion: Simulcasting lets you broadcast on different channels thus allowing you to reach to different geographical locations simultaneously
Cross Platform Engagement: Simulcasting allows you to reach audiences that are present on different platforms. Like some people are on YouTube and others are on Facebook
Broadcasting on different platforms allows you to reach audiences that are present on those platforms.
2. Enhanced Viewer experience
Accessibility: Viewers can view the content on their preferred platform thus enhancing the accessibility and improving convenience for viewers
Resource optimization: Simulcasting uses the same feed and thus the same content and reaches to a wider audiences thus there is no need to create different content for different distribution channels and thus optimizing the resources for content creation
3. Cost Efficiency
Reduction in Operational costs: Simulcasting the same content to different platforms reduces the cost associated with rendering the content as different platforms use their own technologies to reach the audience and you do not have to create your own distribution network to reach audiences
4. Increased Engagement and Interaction
Real time interaction: Nowadays there are livestreaming on social media platforms and also on live streaming and video streaming services. Simulcasting on all the platforms increases publics real time interaction with your video and you can also create interaction tools with live event chats like DeadSimpleChat
Social Sharing: People also social share more when there is a buzz created because a lot of public is watching the same content on different platforms and thus people start sharing content for more people to see and thus the media and content gets boosted on social media platforms
5. Improved Content Marketing Strategies
Content Repurposing: Once the Simulcasting is done then the recorded content can also be repurposed to make other contetn like clips and highlights thus driving more engagement from the same content.
What is the difference between simulcasting, multicasting and standard streaming?
Simulcasting
As we have already discussed simulcasting is the broadcasting across multiple distribution platforms or channels. This is like you are simultaneously broadcasting on YouTube, Facebook and other channels
It is used to expand your reach to a broader audience by accessing audiences that are on other channels and as well as expanding reach geographically
Multicasting
Multicasting is the transmission of a stream of video to multiple recipients on a singular network
Unlike Simulcasting where you are targetting multiple channels and websites across the internet, like streaming on youtube, facebook and other platforms simultaneously, multicasting targets a specific group within a network like pay for view sports matches that are only available on certain networks.
Standard Streaming
Standard streaming involves trnasmitting the content from a single source to a single viewer over the internet.
This one to one on demand video transmission is typically followed by YouTube and Netflix where the user demands a video that the platform sends it
Types of Simulcast
Video simulcasts.
Video Simulcasts involve broadcasting video content simultaneously across multiple platforms.
Applications
Live Events: Concerts, sports events often use simulcasts to reach wider audiences. These events can also be streamed across social media platforms and streaming services
Webinars and educational content: Educational institutions simulcast tranining sessions to multiple digital platforms to maximize the reach
Audio simulcasts.
Audio simulcasting is the simulcasting of audio broadcasting across multiple platforms, these might include audio platfroms and also traditional media such as radio and modern platforms such as podcasts
Hybrid models.
Hybrid Simulcasts involve a combination of audio and video streams, there are complemented by engagement tools such as chat
There are often used in live events and live streaming events for enagement with audiences.
Key Technologies Enabling Simulcasting Streaming protocols (e.g., HLS, RTMP).
What are streaming protocols, these are rules and standards that are defined and designed to establish how the transmission of video and audio data will be through the internet
These protocols ensure smooth delivery of streaming content to the users, different protocols are designed with different use-cases in mind. Some give low latency but have high bandwidth and cpu requirements, others work with low bandwidths but do have some lag in performance
It is upto you and your use-case which streaming protocol you want to use. Also different streaminh platforms and social media platforms support differnt types of streaming protocols and do not support some other types of streaming protocols
While simulcasting you need to have a knowledge of what streaming protocols are supported by the platforms that you are considering simulcasting on and encode your content in the supported formats.
Important or widely supported streaming protocols
HLS (HTTP Live Streaming)
This protocol was developed by Apple, but it is open source for anyone to use and many platforms use this protocol
functionality: HLS breaks the content into smaller chunks and then the device downloads these chunks to create a smooth playback for content
The benefit is that if the device has intermetent connection then when there is connection it quickly downloads the chunks thus smoothing out the playback event in choppy internet
Also, the client has the choice of streams, the client device can select the stream according to its own bandwidth and CPU capacity
HLS you can submit different streams in order to give client devices a choice as to which stream to subscribe to according to their bandwidth and CPU requirements
HLS is widly supported and a good choice for different network conditions
RTMP (Real Time Messaging Protocol)
RTMP was developed by Adobe and it is also open source and anyone can use it.
RTMP is a TCP based protocol which maintains constant connection with the client devices in order to provide low latency streaming. these kinds of streaming is good for sports and other activities
RTMP can stream audi video and data over the internet, RTMP can encapsulate MP3, ACC and various other audio and video formats
RTMP is ideal for live streaming which cannot be done through HLS because HLS has a latency issue
