The past few years have seen a dramatic rise in the distribution channels available to media companies. While media companies once distributed their programming through one or two mediums, such as TV broadcasts and video tapes, the same programming is now also distributed through additional mediums such as the Internet and mobile phones. As a result, the IT systems of these companies are now required to handle both new content formats and to ensure that content is simultaneously and successfully prepared in order to meet scheduling and distribution requirements for multiple delivery pathways. This paper describes a solution that was developed to address the problem. The system presented here was implemented by the Taiwani¦s Public Television Service (PTS) in an effort to improve the effectiveness of daily operation in January 2010 and is currently providing complete support to the companyi¦s daily operations. Since implementation, this automated process has increase the average number of transcoding jobs completed daily from 500 to 700 iV and increase of 40 percent.
