META[CC] seeks to create an open forum for real time discussion, commentary, and cross-refrencing of electronic news and televised media. By combining strategies employed in web-based discussion forums, blogs , tele-text subtitling, on-demand video streaming, and search engines, the open captioning format employed by META[CC] will allow users to gain multiple perspectives and resources engaging current events. The system we are developing is adaptable for use with any cable news or television network.
META[CC] is in its infancy; as the project develops, additional features such as web-based remote channel switching, video archiving, further data-mining capabilities, and on-demand streaming of archived content will be implemented.
