Aspect Ratio Problems in Television Today and Some New Solutions
The proliferation of video source formats, delivery mechanisms, and display devices has significantly increased broadcasters' needs for aspect ratio conversion. As a result, the authors have developed aspect processing, a framework for producing an arbitrary shape intelligently and flexibly. Aspect processing extends aspect ratio conversion to the definition of optimum viewing for a given screen size and shape. This paper presents new aspect processing technologies, which introduce a set of efficient criteria to automatically identify regions of interest in the picture and to process the picture accordingly. The paper also introduces a unique and novel technology—video seam carving, which works by altering the perspective of the image sequence to change between aspect ratios. These new technologies allow broadcasters to access new platforms and audiences with maximum re-use of systems and source material, resulting in a simpler and cheaper infrastructure.
