    Abstract: Teachings herein prepare a digital image for display on a substantially transparent screen. The teachings advantageously recognize that the perceptibility of the digital image on the screen will often depend on what is visible to a user through the screen, since that will effectively serve as the background of the screen. A method of preparing a digital image thus includes dynamically calculating which part of an environmental background is visible to a user through the screen and thereby serves as an effective background of the screen. This calculation may entail obtaining an image of the environmental background and identifying which part of that image serves as the effective background (e.g., based on the angle at which the user views the screen). The method further includes composing the digital image for perceptibility as viewed against that effective background and outputting the composed image as digital data for display on the screen.

    Abstract: A method for facilitating anonymous audio and video communication between at least a first user using a first web browser and at least a second user using a second web browser via a server, and a web based system configured to implement the method, is provided. The method comprises browsing to the server using the first web browser, establishing a signalling channel on the server and creating a first unique identifier for the signalling channel. The first unique identifier may be at least temporarily stored at the server. The first unique identifier is transferred to the second user. The method further comprises browsing to the first unique identifier using the second web browser, whereby an anonymous connection is established between the first web browser and the second web browser.

    Abstract: A method of operating a data-processing unit to produce a transform comprises calculating first and second output data values based at least on first and second input data values. The method comprises reading the first and second input data values from locations of a first buffer, the locations being determined by first and second read addresses based on first and second read indices. The method also comprises writing the first and second output data values to adjacent memory locations of a second buffer during a single write cycle. Furthermore, the method comprises reading third and fourth input data values from locations of the second buffer, the locations being determined by third and fourth read addresses determined by swapping at least two of the bits of the first and second read indices respectively. A data-processing unit for producing a transform, a transform-computation unit and an electronic apparatus are also described.
