The expansion of computing networks and streaming has led to some incredible transformations in how data is transmitted to us through TV. There are two distinct types of transmission: Multicast and Broadcast. They have distinct advantages and differences, which are usable for different cases and according to transmission demand.

Let’s explore Broadcast and Multicast in more depth.

What is Multicasting?

Multicast or multicasting refers to the network transmission method, where multiple copies of a single packet are distributed amongst a dedicated group of hosts within a network. This is usually transmitted amongst a group of hosts that are committed to receiving a single stable packet source. 

In broader terms, the Multicast concept ideally sits well with selective content delivery. The idea of delivering the content/transmission to the one who shows interest or volunteers to consume such data (via subscription model).

Benefits of Multicast 

Now, let us check the advantages of Multicast:

• User-specific only: Since only the subscribers would receive such content, multicast ensures the network experiences only specific levels of traffic transmitted. This, in turn, reduces network congestion and enhances the user viewing experience.

• Privacy at best: Privacy and security layers are significantly enhanced, allowing users with the correct credentials to access the content.

• Best for streaming live: Live Streaming is a functionality that makes multicast transmission ideal for video streaming, and live performance feels better.

• Scalability: Multicast content is highly scalable, and it effectively delivers in situations where multiple users need to receive the same data simultaneously. This makes it available for a large-scale audience enjoying the telecast at the same time.

• Cost Efficiency: The cost of transmission is nominal, considering that only a single form of data is widely distributed amongst the consumers. 

What is Broadcasting?

Broadcast in broader terms refers to the one-to-many transmission, where a single source of data is delivered across the entire network. This has no restrictions, and unlike Multicast, this is open to all, within the network spectrum.

This is perhaps the most widely used variant of streaming and, has been traditionally used by legacy radios and satellite cable channels.

Broadcast is best suited for a broader audience base who intend to view/listen to whatever is available on the channel/frequency.

Although the user base for such broadcasting is higher than Multicasting, there are prominent utility-level differences that separate their target use case.

Benefits of Broadcast

Here are the real benefits of a broadcast network:

• Global Reach: One of the most significant talking points of broadcast is the access a streamer/creator gets to display to the larger audience base. According to a study, the broadcasting market is expected to grow to up to 220 billion USD by 2026.
• Non-complex Interface: The setup to broadcast is easy and doesn’t require any additional or complex configuration.
• Easy troubleshooting: It's easy to verify and troubleshoot network issues and track down if the broadcasting is systematic.

Multicast vs Broadcast: Quick Comparison

Detailed Side-by-Side Differences

Multicast and Broadcast have their own distinctive use-cases and catering bases. As for creators, both these mediums have their own advantages/disadvantages that have an impact when considering a creator’s content strategy. Here are the differences explained one by one:

Data Transmission 

Data Transmission is the most crucial differentiator between Multicast and Broadcast. 

In the case of a Multicast system, only a specific type of receiver would receive the transmission/ content delivery to their network. Furthermore, a Multicast transmission is processed only once, and then the data is parsed across all the approved receivers. 

In the case of a Broadcast system, the information transmitted is universal, and all the devices connected to the device would receive the content/ transmission. For instance, imagine watching a live cricket or football match on a Sports OTT on board. 

Bandwidth

Multicast bandwidth is constant, regardless of the number of audience streams subscribed to under the network. Therefore, this helps in streaming with consistency and ensures there remains no network lag, as the overall bandwidth remains the same. 

Broadcast bandwidth, on the other hand, is usually higher as it multiplies depending on the audience size. This means that as the audience grows, more bandwidth is required to stream.

Types of Content suited for the network

Multicast transmission is ideally suited for content that is suited for a limited group streaming. For instance, a live streaming of any show subscribed to under a monetized package is an ideal example of these transmission types.

Broadcasting, on the other hand, is like a linear satellite transmission, offering a seamless experience while showcasing to everyone within the network spectrum. Imagine watching a concert show on TV, which is made possible by broadcasting transmission.

Quality Control

Multicast requires a stable network infrastructure that ensures a seamless experience received by the paying audience. Any lapse in network triggers that compromises the quality triggers a negative perception among the viewers.

Broadcasting, on the other hand, relies on a regular and predictable network setup that manages a generic flow of streaming. Therefore, the quality is manageable, and the optimization of the viewer experience can be managed individually.

Multicast infra setup might be on the higher side while setting up. However, with the growing number of paid subscribers, the ROI is significantly lower because the bandwidth of the streaming remains the same.

Hence, this opens up for a reasonably better revenue model. Therefore, in enterprise and OTT brands, choosing multicast reduces overhead costs while ensuring predictable streaming expenses.

Broadcast relies heavily on the audience size, which invariably increases the cost of bandwidth expansion. The profitability remains positive, but infrastructure costs increase as more viewers grow.
