Patent number: 9549011Abstract: An audiovisual signal is converted from a native format to a digital, packetized interchange format and transported between a capture node and a display node through a switch. The display node converts the audiovisual signal from the interchange format to a displayable format and causes display of the audiovisual signal. The use of a switch for video routing and distribution allows one-to-one, one-to-many, many-to-one, and many-to-many distribution. The use of a device-independent interchange format allows concurrent distribution of multiple heterogeneous audiovisual signals.Type: GrantFiled: December 10, 2013Date of Patent: January 17, 2017Assignee: InFocus CorporationInventors: Eric Wogsberg, Jack Klingelhofer, Herbert A. Kutscha

Patent number: 9344681Abstract: The technology disclosed solves the technical problem of incorporating live streaming sources into a video conference. In particular, the technology disclosed relates to pre-registering live streaming sources as pseudo-participants to optionally include in a video conference and causing the live streaming source represented by the pseudo-participant to be streamed to participants in the video conference without relay from one participant to another participant. The technology disclosed also relates to solving the technical problem of controlling a video conferencing interface during a video conference by allowing attendees of a video conference to configure a video interface template that includes areas to display participants and pseudo-participants live streaming sources.Type: GrantFiled: August 21, 2014Date of Patent: May 17, 2016Assignee: InFocus CorporationInventors: Frederick P. Block, Brady O. Bruce, Stanislav Angelov

Patent number: 8081377Abstract: The wide angle lens system described herein allows projection devices (e.g., rear projection display devices) to be more compact than would otherwise be possible. The lens system includes a wide angle lens stage and a relay lens stage. When operating as a projection device, the relay lens stage projects a distorted intermediate image to the wide angle lens stage, which projects the image for display. The distortion cause by the relay lens stage compensates (i.e., is approximately equal and opposite) for the distortion caused by the wide angle stage. The distortion can be the image shape and/or the focal plane. When operating as a taking device, the wide angle stage provides a distorted image to the relay lens stage, which compensates for the distortion and provide a less distorted, or even non-distorted image, for capture.Type: GrantFiled: June 8, 2009Date of Patent: December 20, 2011Assignee: InFocus CorporationInventor: Jeffrey Alan Gohman

Publication number: 20090256867Abstract: Systems, and methods, for calibrating a display device to a content source are provided. After initiating operation of the image display device, and linking it to the content source to transmit an image signal from the content source to the display device, the presence of an image coder may be detected in the image signal. In some embodiments, the image coder may be identified, and a coder level for the image coder may be determined. The display device may then be calibrated based on the coder level. The image coder may be a black level coder. Other example methods may include selecting a color gamut for use with the display device, by identifying an image signal type from the content source. Based on the image signal type, a color gamut may be selected from a store of color gamuts for the image display device to use to display images from the content source.Type: ApplicationFiled: April 10, 2009Publication date: October 15, 2009Applicant: InFocus CorporationInventor: Marques Girardelli
