CPC, Manzanita partner on EIA-708 closed captioning
Computer Prompting & Captioning (CPC) and Manzanita Systems have partnered to deliver MPEG-2 HD closed captioning for broadcast.
CPC’s MacCaption-HD closed captioning software now interfaces seamlessly with all three Manzanita software multiplexers (MP2TSMS, MP2TSMM and MP2TSME) to generate a transport stream file that contains EIA-708 closed captioning. This functionality is important because an increasing number of TV broadcasters demand post production houses deliver MPEG-2 transport stream files instead of traditional high-definition tape masters.
Strict FCC broadcast regulations require these HD transport stream files to have both EIA-608 and EIA-708 closed captions for the hearing impaired. (EIA-708 is the HD/DTV captioning protocol; EIA-608 was the closed captioning protocol prior to HD).
MacCaption-HD also allows TV stations to check MPEG-2 transport streams for both 708 and 608 captions before they air a show.
