Abstract: At the SMPTE ‘97 Conference in Sydney, the concept of representing motion picture film images in a universal data format was presented. Since then, the enabling technology has met with widespread acceptance, with over 140 units of the core product installed worldwide. In addition, several key building blocks have been added by the same supplier to extend the film-in-data concept, allowing the full power and flexibility of computer workstations (coupled with tremendous hardware acceleration) to be applied to the creative and post-production processes. The successful data concept can even be “tunnelled” through the high-definition video domain, allowing the major benefits of the data process to be achieved in realtime using low cost video tape storage. This paper examines these advances and illustrates some of the real world applications for this new technology.

bio
Dave Bancroft is business and technology development manager for the Film Imaging Group of Philips Digital Video Systems. Although his group is based in Weiterstadt, Germany, Bancroft operates out of the U.K. and contributes to long-term projects, such as DTV production, in the U.S. Bancroft began his career in broadcast engineering at the BBC in London, where he received his fundamental training and became an operations and maintenance engineer on outside broadcasts. He became particularly interested in videotape recording and related mechanical wonders and this led to an international odyssey, which kept him away from the U.K. for 20 years. During this time, he worked for RCA in Germany, Ampex Corp. in Greece, the Middle East, Africa, New York, and California. He joined Philips Digital Video Systems, or as it was formerly known, BTS, in 1992, with the assignment of HDTV marketing in Darmstadt. He moved his desk back to the U.K. in 1995 and took up his present position with Philips in 1997. Bancroft is a long-time member of SMPTE, where he represents Philips in several technology committees. He is an International Member of SMPTE's Executive Standards Committee. He is also a member of the Royal Television Society and the BKSTS in the U.K.

17. Two kinds of prefiltering are encountered in television image sensing; both progressive scan and interlaced scan sensors require optical prefiltering in both horizontal and vertical directions to prevent aliasing between high-frequency optical image information and the sensor or scanner pixel/line structure; where it is known that the reproduction of the image will use a display operating in an interlaced mode, this is a further resampling in the vertical axis; the additional vertical filtering that is required could be applied after the sensor (but before the display), but it has been common practice to apply this secondary filtering at the same time as the primary anti-aliasing filtering in the sensor. This technique cannot be used for segmented-frame image sensing—the secondary filtering must be associated only with interlaced displays in the instances these are used, otherwise vertical resolution is lost unnecessarily when the same image is displayed with progressive scanning.
