Abstract: A multichromic reflective coating is applied to a projector screen to reflect only those wavelengths produced by the projector, to accentuate selective wavelengths of light to be reflected. The screen can be a passive black substrate or an active grayscale screen such as e-ink paper, and un-reflected light reaches the screen which selectively tunes its grayscale to accentuate the brightness or darkness of the color video image being projected onto it and reflected by the multichromic reflective coating.

Abstract: A customer can install a lenticular projection screen without the need to hire a professional installer. A section of a home wall is smoothed flat and lenticular tiles are applied to it with adhesive together establishing a lenticular projection screen. Once the adhesive has dried, a short throw projector can perform an automatic alignment to gain the best possible picture from the lenticular screen. The installation material may be provided as a kit that a consumer can use to install the lenticular projection screen.

Instead of on a wall, the wallpaper may be placed on a stiff flat surface hung from an overhead bracket or attached to a backside wall mount.

Abstract: For each network or type of content in an Android TV application, a main icon may be presented on a display, and when the screen cursor is positioned over a main icon, 3-5 sub-icons are presented under the main icon. Moving the screen cursor to another main icon causes the first sub-icons to disappear and new sub-icons relating to the new main icon to appear under the new main icon. Each sub-icon represents content associated with the main icon either using trending information, automatic content recommendation (ACR), time of day, etc. The user may select a sub-icon to show the related content. Thus, for each Android TV application, the most important, trending, live, or personal content is made available through the sub-icons such that a limited number of live content subsets is presented to choose from for that network at that moment.

Abstract: A glass (or other transparent) substrate such as a window is used for large screen video projection to permit viewing at an outdoor location (or opposite side of the substrate) of a video projector's image directed from a location in the home. The projector image is sent through an articulated glass window pane (substrate). Alternately a projector such as an ultra short throw (UST) projector can be completely located behind the transparent glass pane located in a home separating two rooms. In either case, the video image can be projected onto the substrate when desired, and when no video is being shown the substrate functions as a window or displays window art as a wall covering.

Abstract: ACR is used to identify content viewed by a person watching an AVDD such as a smart TV. Content searches of multiple sources and source types may be conducted and the results arranged for presentation by weighting each item of the search result according to the ACR identifications of historical viewing.

Abstract: A sequence of photographs is taken of the face (and if desired the upper body) of a user of a mobile device using the camera of the mobile device. Each photo is taken at a different angle from the user. The sequence is compared with a stored sequence and if a match is found, access to the device is granted. The user typically holds the device with arms extended outward and moves the device 180° across his face to take the sequence for authentication purposes.

Abstract: To avoid requiring precise alignment between a projector and a projection screen, plural micro etched faceted grooves are provided for each area of the screen onto which a single pixel is to be projected. Each facet may be roughened, or gently curved, and the walls between adjoining facets likewise may be curved.

Abstract: Meta-material with individually-addressable elements is applied to a video projector screen to dynamically control light reflectance and grayscale. Example meta-material includes piezo electric elements, liquid crystal elements, and electrochromic elements. Methods of calibrating the screen with meta-material are disclosed. In one embodiment the screen is adjustable pixel by pixel. In another embodiment the screen is adjust by multi-pixel spans per line of meta-material. A camera may be used to provide feedback to the alignment system to make corrective adjustments to the screen.

Abstract: A viewer's rights to view content is determined instantly, without exposing any data externally, by capturing both a facial image and speech of the viewer. The data, which can be captured each viewing session, is matched to a secure profile which may have other security information assigned to it, such as service login IDs and passwords, or credit card numbers. If both the facial image and voice match respective templates, the viewer is allowed access to, e.g., cloud-based content (such as email) or is allowed to make a purchases within applications via account level access. Banking transactions may similarly be permitted upon face/voice match without the need to input a code. Personalization of content based on profiles recognized automatically during a viewing session is also facilitated.

Abstract: An audio video device (AVD) is activated post-sale using an unlock code issued during the purchase. The buyer connects to his home network and enters the unlock code issued in the store at the point of sale. Then a server associated with the seller can complete the transaction and unlock the AVD for full functionality. In the event the AVD is reported stolen before activation, it can be blocked from use. When in the reduced functionality mode” the AVD can remain in demonstration mode or other reduced functionality state (e.g., only works with HDMI1).
