Abstract: A tree display is made in a tree display area of a play list display area as of the contents files were classified in a directory structure, but in reality the contents files are not classified in a directory structure. In the tree display area, the heading “All music pieces” is not located at the lowest hierarchical level of the tree structure but partway up the structure, and in the event that “All music pieces” is selected, the contents are searched with an item corresponding to the parent thereof as the search key, and data relating to the corresponding contents is displayed in a list display area, so in a case described herein, contents matching the genre of “Blues” and artist name of “4 hero” are displayed on the list display area. Thus, desired contents files can be easily searched for.

Abstract: As an imaging prevention method for interfering unauthorized imaging of a number of visual images projected on a screen, there is employed a method for projecting infrared light to a viewer/audience direction from at least one or more infrared light projector devices disposed at a rear side of the screen. According to the method, an amount of infrared light is directly incident into an imaging apparatus whereby increasing the prevention effect causes more infrared light to be directly incident into the imaging apparatus of a person conducting the unauthorized act.

Abstract: This proposal describes an optimized synchronization (SYNCH) symbol sequence to be used in transmission systems, which are currently under standardization. The synchronization symbol is constructed using specially designed OFDM (orthogonal frequency division multiplexing) symbols with an optimized sequence, which is mapped onto the modulated subcarriers. The resulting synchronization symbol consists of several repetitions in the time domain. Using the proposed sequence the resulting synchronization symbol achieves a high timing detection and frequency offset estimation accuracy. Furthermore the burst is optimized to achieve a very low envelope fluctuation (low Peak-to-Average Power Ratio) and a very low dynamic range to reduce complexity on the receiver and to save time and frequency acquisition time in the receiver. The proposed sequence is furthermore optimized with respect to all other synchronization symbols that are used to construct the synchronization and training preambles for the BCCH-DLCHs.

Abstract: An optical communication system wherein a light emission circuit operates with reduced power consumption. The optical communication system is used in a communication network wherein communication is had between a control node and plural controlled nodes using light rays amplitude-modulated with carrier modulation signals over 6 MHz. The control node transmits a transmission permission signal to each controlled node, which starts or interrupts light emission with desired transient characteristics by having reference to the transmission permission signal. For example, the amplitude of the infrared light rays is increased or decreased over e.g., a period as indicated at I1.

Abstract: Three-dimensional image processing has two processes. In a first process, a three-dimensional space including only a horizon appears on a display screen. By drawing a stroke line in the space, a wall having the stroke line as the base line is set as a canvas. A picture drawn by a user is mapped onto the canvas, resulting in a three-dimensional picture. By repeatedly setting the canvases and pictures, a desired scene can be constructed. A desired three-dimensional scene can further be obtained by rotating the canvas or moving the viewing point. In a second process, the base line of the canvas is constantly displaced between a first curve, a second curve, and an interpolation curve. The three-dimensional image pasted on the canvas is moved in accordance with the movement of the canvas. Thus, it appears to the user that the three-dimensional image is animating.
