Editing Closed captioning (section)

=== Digital television standard captioning improvements ===
The [[CTA-708|CEA-708]] specification provides for dramatically improved ''captioning''
* An enhanced character set with more [[Diacritic|accented letters]] and non-Latin letters, and more special symbols
* Viewer-adjustable text size (called the "caption volume control" in the specification), allowing individuals to adjust their TVs to display small, normal, or large captions
* More text and background colors, including both transparent and translucent backgrounds to optionally replace the big [[black]] block
* More text styles, including edged or [[drop shadow]]ed text rather than the letters on a solid background
* More text fonts, including [[monospaced]] and proportional spaced, [[serif]] and [[sans-serif]], and some playful cursive fonts
* Higher [[Bandwidth (computing)|bandwidth]], to allow more [[data]] per minute of [[video]]
* More language channels, to allow the encoding of more independent caption streams
As of 2009, most closed captioning for digital television environments is done using tools designed for analog captioning (working to the [[EIA-608|CEA-608]] [[NTSC]] specification rather than the [[CTA-708|CEA-708]] [[ATSC standards|ATSC]] specification). The captions are then run through transcoders made by companies like EEG Enterprises or [[Evertz Microsystems|Evertz]], which convert the analog [[EIA-608|Line 21 caption format]] to the digital format. This means that none of the [[CTA-708|CEA-708]] features are used unless they were also contained in [[EIA-608|CEA-608]].
