System for real time video production and multicasting

An integrated, fully automated video production system provides a video director with total control over all video production devices used to produce and broadcast a show. The video production system includes a processing unit that communicates with one or more video production devices and supports production automation. A video director defines a set of video production commands or instructions ("transition macro") to be executed by the processing unit, and then, by activating a control button displayed by the processing unit, the video director instructs the processing unit to execute the transition macro. The processing unit also records the show or elements from the show following its production. The show or elements can be recalled for subsequent broadcasts. An Internet interface supports live or on-demand requests for content from the video production. An online user can select specific elements and reorganize the elements to personalize a broadcast. The processing unit receives and executes the online request to continuously stream or download the content to the user.
