Why Broadcast Video and Content in HTML5?

Broadcasting content in HTML5 allows anyone to stream video across multiple devices.

You may have already heard of or even used HTML5–perhaps without knowing it! According to BitMovin’s 2017 Video Developer Report, HTML5 is the most popular platform for all video playback. Today, you’re using HTML5 when broadcasting live video streams on your mobile phones. This is true whether or not you actually know how to broadcast video in HTML5.

The same goes for on-demand video content. Unlike Flash, which is a dying technology, HTML5 is compatible with both Android and iOS-based devices. The cross-platform functionality of HTML5 helps to create a seamless visual experience for people streaming across multiple devices. These compatible devices include computers, smartphones, and tablets, all on different operating systems.

HTML5 is a newer and more current web programming language. As such, it has the capacity to reach broader audiences than ever before. You might have noticed that many video streaming platforms, including Dacast, are now shifting to HTML5. If you are familiar with HTML4, then getting up to speed with HTML5 will be a piece of cake. If you’re new to HTML in general, however, not to worry! In this article I’ll help you to understand how to broadcast video in HTML5–both live and on-demand content–in layperson’s terms.

The Nuts and Bolts of HTML5

Before we jump into how to broadcast video in HTML5, let’s consider the why.

First, it’s helpful to understand that HTML5 is not simply a particular update from HTML. In reality, HTML5 is a comprehensive upgrade to the older platform.

In particular, HTML5 is ideal in terms of accessibility. With HTML5, your screen readers can easily access the given content with new HTML headings like <header>, <footer>, <nav>, etc. This feature helps to create proper landmarks for the users of given video content. Let’s take a closer look at these innovative features.

Comprehensive Accessibility

A key reason to broadcast live video in HTML5 is its comprehensive accessibility. This means that you don’t need a third-party media player in conjunction with HTML5. When all of your content is completely accessible via HTML5, there’s no need for Flash or Java. With HTML5, you can integrate the video and audio right into the code itself. Additionally, all major browsers support HTML5, which makes this coding platform even more attractive to broadcasters.

HTML5 Feature Highlights

For all those code-savvy folks out there, HTML5 also has <!DOCTYPE html>. This means you don’t need to waste time on cutting and pasting code anymore.

HTML5 also offers a local storage feature. Without getting too technical, this feature is a cross-over between cookies and client-based databases.

HTML5 is fairly successful in terms of its interactive features as well. It is quite dynamic. This helps users to connect and interact with the content very easily.

If you tend toward compulsive when it comes to coding, HTML5 is best for you! Its simple and clean codes allow you to easily read, write and edit. There’s no need to fuss with complicated div tags. You can just replace them with semantic HTML codes. All this means that HTML5 is more consistent and accessible than previous alternatives.
