AOL is expanding the closed captioning it provides on some of its Web video services to its CNN news features.

Some video on AOL’s KOL kids service has been captioned since 2003, the Web company said in a Thursday announcement. In the past, AOL has offered synchronized anchor transcripts for its CNN updates.

The captioning project was supported by a grant to WGBH-TV’s Media Access Group, AOL’s partner in the initiative. The captioning is done manually.

As with TV programs, which are required to be closed-captioned from 6 a.m. to 2 a.m., the captions are displayed directly beneath the video window. The AOL captioning is activated by clicking on the “CC” button on AOL’s media player.
