Closed Captioning


Closed captions are the text version of the spoken part of a television, movie, or computer presentation. Closed captioning was developed to aid hearing-impaired people, but it's useful for a variety of situations. For example, captions can be read when audio can't be heard, either because of a noisy environment, such as an airport, or because of an environment that must be kept quiet (for example, in a hospital).

Closed captioning information is encoded within the video signal, in line 21 of the vertical blanking interval (VBI). The text only becomes visible with the use of a decoder, which may be built into a television set or available as a set-top box . In general, an onscreen menu on newer televisions allows you to turn closed captioning on or off. Open captions, in contrast, are an integral part of a transmission that cannot be turned off by the viewer.

Most programs are captioned in advance of transmission, but the nature of some programs, such as live news broadcasts, requires real time captioning. For real time captioning, a stenographer listens to the broadcast and types a shorthand version into a program that converts the shorthand into captions and adds that data to the television signal.

"We can store media content with either CEA-708 or CEA-608 Closed Captioning formats and convert them live as you play-out media content from our "Hybrid" Channel-In-A-Box automation video servers", notes Alex Sadovsky Skylark Technology President. The Skylark system has the capability to store and play-out Closed Captioned media content regardless of whether the media content and Closed Captioning metadata is imported via short or long-form recording or file transfer.

Also available as a standard feature on the Skylark SL NEO Series is live-manual Closed Captioning data entry capability. "Broadcasters that produce TV shows can add or import Closed Captioning metadata to their media content files," notes Sid Guel, Skylark Technology Business Development. "Any keyboard connected to the Skylark system via direct, LAN, or WAN can be used as a real-time Closed Captioning data entry point. The Closed Captioning metadata is stored in the Skylark database for play-out to air," continues Guel. The Closed Captioning metadata can also be exported as metadata within media content files in SD-CEA-608 or HD-CEA-708 formats.
Skylark's HD/SD NLE NewsCut editing system supports Closed Captioning. The NewsCut editing system has two edit modes, Hard-Cuts editing or EDL editing. The Skylark "Hybrid" Channel-In-A-Box system automatically determines the editing mode used and auto-selects the appropriate Closed Captioning metadata for on-air or production play-out.
The Skylark Graphics system supports Closed Captioning during design and play-out. During the graphics design phase, Skylark has the ability to store manually-entered Closed Captioning metadata. If the graphics design involves rolling video content with built-in Closed Captioning metadata, the Skylark "Hybrid" Channel-In-A-Box system gives broadcasters the ability to select either the manually entered Closed Captioning metadata or the Closed Captioning metadata built-in to the video media content for on-air or production playout.
"Broadcasters want to do more with less, add value to their channels, and develop new revenue streams with only an incremental increase in costs," said Guel, Business Development - Americas.  "The premise of "Channel-in-a-Box" is cost savings and today Skylark can offer broadcasters quality video and audio, on-air reliability, a smaller footprint, and cost savings, in one system."
