Patent number: 6400411Abstract: The invention overcomes the need to adjust the video level settings of different video capture devices for each source by saving each setting as a difference between the actual setting and a default setting when digitizing source material. These saved differences are called differential settings. An actual setting for another capture device that provides consistent video levels when digitizing the same source may be derived from both the differential setting obtained when digitizing using the first capture device and the default setting of the other capture device. As a result, source material is mapped to consistent internal digital levels when used on the different devices. Accordingly, video characteristics such as gain, black, saturation and hue can be maintained correctly regardless of the unique settings due to manufacturing and calibration tolerances of the different video capture devices.Type: GrantFiled: January 13, 1998Date of Patent: June 4, 2002Assignee: Avid Technology, Inc.Inventors: Stephen A.

Patent number: 6370198Abstract: A multi-format digital video production system enables a user to process an input video program to produce an output version of the program in a final format which may have a different frame rate, pixel dimensions, or both. An internal production format of 24 fps is preferably chosen to provide the greatest compatibility with existing and planned formats associated with HDTV standard 4:3 or widescreen 16:9 high-definition television, and film. Images are re-sized horizontally and vertically by pixel interpolation, thereby producing larger or smaller image dimensions so as to fill the particular needs of individual applications. Frame rates are adapted by inter-frame interpolation or by traditional schemes, including “3:2 pull-down” for 24-to-30 fps conversions. Simple speed-up (for 24-to-25 conversions) or slow-down (for 25-to-24 conversions) for playback, or by manipulating the frame rate itself using a program storage facility with asynchronous reading and writing capabilities.Type: GrantFiled: May 6, 1999Date of Patent: April 9, 2002Inventor: Kinya Washino
