Abstract

A method and apparatus for video editing and realtime processing which generates clips. Each clip includes data identifying a scene of a video or audio program, and data identifying processing operations to be applied to the scene. In preferred embodiments, control signals generated from the clips are supplied to a storage subsystem and a processing subsystem. In response, the storage and processing subsystems assemble and process, in realtime, an edited video or audio program from raw scene data stored in the storage subsystem. Typically, each clip contains content data determining the content of a scene (e.g., 'begin' and 'end' frames of a stored segment of video data) and also processing data (for use by the processing subsystem) identifying processing operations to be performed on a particular scene (or portion thereof) when assembling an edited program from stored scenes. In preferred embodiments, the system of the invention includes an edit controller programmed with software for generating and modifying the clips, and storage and realtime processing subsystems operating under control of the edit controller. The edit controller supplies control signals generated from a sequence of the clips to the storage subsystem and processing subsystem. The processing subsystem preferably includes dedicated hardware for processing scenes of video data (read out from the storage subsystem in response to the control signals from the edit controller) in realtime (while the video data is read out from the storage subsystem) in accordance with the processing data determined by the control signals from the edit controller.
