Abstract: Techniques for enabling the display of video content is a specified display mode, such as the Ultra-High Definition Alliance Specified Reference Mode (UHDA-SRM). A video source device receives video content as a bitstream in one format that includes a specification of a display mode for the video content. The video source also receives information from a display device or other video sink on the display modes that it supports. If the display device supports the specified display mode, the video provides the video content to the display in a second format, such as HDMI, as a series of frames the specification of the display mode embedded in a blanking interval in each of the frames.

Abstract: An apparatus for use in a high-definition media interface (HDMI) source device includes an HDMI interface for transmitting video data and metadata to a sink device. The apparatus is configured to encode the metadata in an auxiliary video information (AVI) information frame (InfoFrame). The apparatus is further configured to transmit the AVI InfoFrame during a frame synchronous transmission window (FSTW) of the video data, wherein the FSTW begins during a video blanking interval (VBI) of the video data, on a first video blank pixel that immediately follows a last active video pixel of a preceding video frame or video field and ends a predetermined number of video lines after a start of the VBI.

Abstract: A source device includes a forward error correction encoder circuit to generate error correction protected blocks from video data packets. Each error correction protected block includes data words and error correction words. An encoder circuit encode X-bit words of the error correction protected blocks into Y-bit encoded words for transmission to a sink device over one or more multimedia lanes of a multimedia communication link, where X is smaller than Y.

Abstract: Aspects relate to transmission of metadata from a source to a sink device, and optionally through one or more intermediaries. A source device encodes metadata into what would have been a blanking area of a field to be transmitted, according to a current video format. The source device encodes a timing for an active video data signal that is modified from a timing that would be used only for transmission of video data at a current resolution. A separate indicator from the source, or a negotiation between source and sink allows the sink to determine what part of the data indicated as being active video data is metadata, and to use that metadata for controlling aspects of the video display, and to use other parts of the received video data as video data for display. A sink can signal supported capabilities to a source.

Abstract: A system and method for automatically creating a three-dimensional (3D) model for use in a design application, such as a transportation planning and design application that supports roadway, bridge or drainage design. A user at a client computer selects an area of interest (AOI) on a two-dimensional (2D) map, as well as one or more data sets to be used, and then submits a model creation request to a server computer. The server computer automatically aggregates one or more data sources to generate a 3D model of the area of interest. At least one of the data sources comprises a curated database. The server computer publishes or stores the 3D model into a database, for subsequent downloading to the client computer. The 3D model is a proprietary model owned by the user, and is fully editable by the user.
