unusual facts about closed captioning

Closed captioning, used to provide the text of a show's audio portion to those who may have trouble hearing it


Norpak

Norpak's products, now part of and complementary to the Ross Video line, include equipment for embedding data in a television or video signal such as for closed captioning, XDS, V-chip data, non-teletext NABTS data for closed-circuit data transmission, and other data protocols for VBI transmission.

Rob Todd

Todd succeeded in efforts to provide closed captioning on Houston's government-information Government-access television (GATV) channel so that weekly televised city council meetings would be accessible to the hearing-impaired.

Vertical blanking interval

In analog television systems the vertical blanking interval can be used for datacasting (to carry digital data), since nothing sent during the VBI is displayed on the screen; various test signals, time codes, closed captioning, teletext, CGMS-A copy-protection indicators, and various data encoded by the XDS protocol (e.g., the content ratings for V-chip use) and other digital data can be sent during this time period.
