Title: The Innovative Contributions of Christopher B Lea
Introduction
Christopher B Lea is a notable inventor based in Montreal, Canada. He has made significant contributions to the field of nonlinear editing systems, holding a total of 3 patents. His work has advanced the way audio and video editing is approached, providing innovative solutions for real-time rendering.
Latest Patents
One of Christopher B Lea's latest patents is a nonlinear editing system and method of constructing an edit therein. This system is designed for audio, video, and other source materials. It includes a mechanism to define at least one timeline representing the edit, which is depicted as an operator graph. The operator graph consists of operators that represent sources and time-based effects, along with time-varying connections between them. For each period of the defined timeline where the connections remain unchanged, an expression tree is extracted. This tree provides a simplified representation of the operators and connections necessary to render that portion of the timeline. The expression tree can be analyzed to ensure that all required sources and connections are available for real-time rendering. If not, it allows for the determination of which portions can be pre-rendered to an intermediate result, facilitating efficient real-time rendering.
