BATH, UK – British researchers have solved the problem of video scaling by developing a new video codec that uses vectors instead of pixels for continuous tone images.<\/p>\n
Conventional digital video is represented by a grid of pixels, which are not scalable and have to be rendered to a fixed size, thus limiting the distribution of digital video films to the formats for which they have been prepared. For example, standard TV is rendered at 768×576, HD TV at 1920×1024 and Internet and mobile phone video at anywhere from 384×256 on up.<\/p>\n
Researchers first developed a vectorizing codec for photographic images and authors John Patterson, Christine Taylor and Philip Willis published their work in a paper entitled Reconstructing Vectorised Photographic Images (2009)<\/a>. \u00a0The result was the VPI format (Vectorized Photographic Images) and the research paper shows some pretyy impressive results.<\/p>\n Building on this earlier work Philip Willis and John Patterson of the University of Bath in England developed a vector video codec that they predict will replace the current pixel video format within five years.<\/p>\n
