Abstract: In one implementation, a method for spatially designating private content. The method includes: presenting, via a display device, an indication of a private viewing region relative to a location of the computing system; determining a first location for presentation of graphical content; and presenting, via the display device, the graphical content at the first location. The method further includes: transmitting a characterization vector associated with the graphical content to at least one other device for display thereon according to a determination that the first location of the graphical content is outside of the private viewing area; and forgoing transmission of the characterization vector associated with the graphical content to the at least one other device according to a determination that the first location of the graphical content is inside of the private viewing area.

Abstract: A system includes a display screen positioned to display on an exterior of a host vehicle, a user interface of the host vehicle, and a computer communicatively coupled to the display screen and the user interface. The computer is programmed to, in response to detecting a target vehicle having prespecified indicia, instruct the user interface to output an instruction to an occupant of the host vehicle, and in response to detecting personnel from the target vehicle, instruct the display screen to output a message to the personnel.

Abstract: Systems and methods for wireless transmission of uncompressed HDTV signals are disclosed. In one embodiment, a method for transmitting an uncompressed HDTV signal over a wireless RF link, comprises providing a stream of regenerated data from the uncompressed HDTV signal; providing a first clock signal synchronized to said stream of regenerated data; encoding said stream of regenerated data, producing a stream of encoded data; providing a second clock signal synchronized to said stream of encoded data; demultiplexing said stream of encoded data, using said second clock signal, into an I data stream and a Q data stream; modulating a carrier with said I data stream and said Q data stream; and transmitting said carrier in a signal over the wireless RF link.

Abstract: A method for transmitting and receiving an uncompressed HDTV signal over a wireless RF link includes steps of: providing a clock signal synchronized to the uncompressed HDTV signal; and providing a stream of regenerated data from the uncompressed HDTV signal, with the clock signal synchronized to the stream of regenerated data. The clock signal is then used for demultiplexing the stream of regenerated data into an I data stream and a Q data stream. The method further includes steps of: modulating a carrier with the I data stream and the Q data stream; transmitting the carrier over the wireless RF link; demodulating the carrier so that the I data stream and the Q data stream are recovered; multiplexing the I data stream and the Q data stream into a single stream of HDTV data; and recovering the uncompressed HDTV signal from the single stream of HDTV data.

Abstract: A system for transmitting and receiving an uncompressed HDTV signal over a wireless RF link includes a clock that provides a clock signal synchronized to the uncompressed HDTV signal and a data regeneration module connected to the clock, which provides a stream of regenerated data from the uncompressed HDTV signal. A demultiplexer demultiplexes the stream of regenerated data, using the clock signal, into an I data stream and a Q data stream. A modulator connected to the demultiplexer modulates a carrier with the I data stream and the Q data stream. A demodulator receives the carrier and demodulates the carrier so that the I data stream and the Q data stream are recovered. A multiplexer connected to the demodulator multiplexes the I data stream and the Q data stream into a single stream of HDTV data so that the uncompressed HDTV signal is recovered.
