Abstract: 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.

Abstract: A method and apparatus is provided in which a digital image is transmitted to a presentation projector resource over a wireless transmission medium using a reduced amount of transmission bandwidth by transmitting a subset of the digital image data. The subset image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. The subset image data may also be a scalable vector graphics representation of the subset of the digital image. Header data is provided to further describe the subset image data. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received.
