Abstract: Methods and systems are provided for associating and editing audiovisual material and graphics information. Audiovisual material is captured from at least one source, and graphics information is generated by a graphics generator. A graphics integration module allows insertion and editing of the graphics information when the audiovisual material is edited. The edited audiovisual material and edited graphics information is output for broadcast such that the edited graphics information appears at the correct time relative to when the edited audiovisual material is output.

Abstract: A digital video effects generator includes: circuit for up-sampling the digital video component signals prior to their spatial transformation and linear interpolation, thereby reducing losses due to the (sin x)/x frequency response of the sampled video signal; circuit for spatially-mapping video motion data representing the degree of video data motion between temporally adjacent video frames and for motion adaptive interpolation to selectively blend interpolated video field data in accordance therewith; circuit for pre-transform keying, thereby allowing two video signal transformations to be keyed simultaneously; circuit for selectively transforming portions of input video signals, thereby allowing selective keying of non-spatially transformed video into selected regions of the video image; circuit for selectively linking keyframes within separate effects and providing smooth parametric transitions therebetween, thereby allowing several separate effects to be combined into a single effect with smooth parametr
