Exploring the Differences between SDH and Closed Captioning

As digital media continues to evolve, the importance of inclusive content becomes more apparent. In the context of accessibility, subtitles and closed captions play a crucial role. For individuals who are deaf, hard of hearing, non-native speakers, or simply in a noisy environment, these text alternatives provide necessary access to multimedia content.

Two phrases you might have heard bouncing around are SDH (Subtitles for the Deaf and Hard of hearing) and closed captioning. They're often used interchangeably, but they're actually not quite the same thing. This article is going to break down what sets them apart and how Happy Scribe can help you to include SDH and closed captioning in your videos.

What are SDH and Closed Captioning

Before delving into their differences, it is important to understand what SDH and closed captioning are.

1. SDH (Subtitles for the Deaf and Hard of hearing)

SDH is an enhanced subtitle format that not only provides dialogue transcription, but also includes essential non-speech elements. This can be sound effects, musical cues, speaker identification, and other significant auditory elements, ideal for those who might not be able to hear the audio. SDH is particularly important for cinematic video content.

2. Closed Captioning

Closed captioning is a written version of what you hear in a video. It shows on the screen all the words that are spoken, but it also tells you about other sounds that are happening, like a door slamming or a song starting to play. It's something you can turn on or off when you're watching a video. Not only that, but it's really helpful for people who can't hear well, but it's also useful if you're in a loud place or if you're trying to understand a language better.

One thing to note is that closed captions can usually be turned on and off by the viewer. So, they're there when you need them, and gone when you don't.

The differences between SDH and Closed Captioning

Now that we know what SDH and closed captioning are, let's take a closer look at the differences.

Closed captions have been the go-to phrase in North America for decades, while subtitles have covered all forms of timed text in the UK and elsewhere. But with the explosion of streaming content and media going global, these terms have been tossed around, leaving viewers and users wondering what sets SDH and CC apart:

User Accessibility and Flexibility

The most prominent difference is that closed captions can be toggled on or off by the viewer, providing flexibility to the user. In contrast, SDH, as a form of subtitle, is typically embedded in the video and cannot be turned off.

The Looks

SDH subtitles can look pretty much like closed captions, or whatever style a media outlet wants. They could also take the form decided by the video player or platform, regardless of what the original captioner intended. Occasionally, the viewers themselves can tweak how SDH looks, but that depends on the video player or platform.

By default, closed captions have the classic white text on a black box look. They're positioned according to the captioner's choice, but digital TV and new captioning standards have allowed viewers to customize them.

How SDH and CC’s are Encoded

Switching from old-style TV to HD changed how we encode closed captions and subtitles. Old 608 closed captions are sent as a stream of commands, codes, and text, and 708 captions go via MPEG-2 video streams. Subtitles are usually sent as tiny dots or pixels, which works better with digital media.

Blu-ray can't do traditional closed captions but handles SDH subtitles just fine, and it's the same with some streaming platforms. SDH is becoming the go-to since these platforms can't do old-school closed captions, but some classic formats like SCC are still being used in both TV and digital.
