Improved acquisition of system information of another cell

Abstract: Method for informing a mobile terminal (MN), which is located in a first cell, on system information of a second cell. In particular, pointers to the system information are transmitted from the base station of the first cell to the mobile node, while the mobile node is located in the first cell. The MN processes said pointer, comprising e.g. information on the transmission format and timing of system information in the second cell. Using an acquisition gap assigned by the network, the MN changes the frequency to the second frequency so as to acquire the system information based on the previously received scheduling information. Thus, the acquisition time for important system information may be reduced, as no Master Information Block on the second frequency has to be processed first, in order to acquire the system information.

Recording/reproducing method suitable for recording/reproducing AV data on/from disc, recorder and reproducer for the method, information recording disc and information processing system

Abstract: The present invention relates to a method for recording an AV file using an information recording disk in which data is recorded/reproduced by sectors. The recording method includes the steps of: determining whether or not input data is AV data; detecting a defective sector existing in an assigned data recording area; when the input data is AV data while a defective sector is detected in the data recording area, allocating a defective extent including the defective sector; recording AV data in continuous sectors while skipping the defective extent; and allocating an area of continuous sectors where only the AV data is recorded as one AV extent.

Illuminating apparatus, display panel, view finder, video display apparatus, and video camera mounting the elements

Abstract: Light emitted from a white LED 15 is converted by a lens 11 into light having an excellent directionality. The light illuminates a display panel 863 from the direction of an angle θ k . The display panel 863 is a polymer dispersed liquid crystal display panel in a normally white mode. The display panel 863 modulates incident light by scattering it, the scattered light is incident on a magnification lens 866 , and light from the magnification lens reaches an eye 21 of the observer. Light which passes straight through a liquid crystal layer in the display panel 863 is absorbed by an optical absorbing film 12 . The observer fixedly positions his/her eye 21 to an eyepiece cover 852 and observes the displayed image.

Compound objective lens having two focal points

Abstract: A compound objective lens is composed of a hologram lens for transmitting a part of incident light without any diffraction to form a beam of transmitted light and diffracting a remaining part of the incident light to form a beam of first-order diffracted light, and an objective lens for converging the transmitted light to form a first converging spot on a front surface of a thin type of first information medium and converging the diffracted light to form a second converging spot on a front surface of a thick type of second information medium. Because the hologram lens selectively functions as a concave lens for the diffracted light, a curvature of the transmitted light differs from that of the diffracted light. Therefore, even though the first and second information mediums have different thicknesses, the transmitted light incident on a rear surface of the first information medium is converged on the its front surface, and the diffracted light incident on a rear surface of the second information medium is converged on the its front surface. That is, the compound objective lens has two focal points.

Method and apparatus for providing electronic program guide information from a single electronic program guide server

Abstract: A method and apparatus for requesting, receiving, processing, and providing information from a single source to a television viewer. An information provider is accessed via a communications link and specific data, which is separate and distinct from video signals received by the television receiver, is downloaded to the television receiver. The data provided by the information provider is database information with minimal formatting and does not contain any graphical overhead. Requests for information from the information provider may be on demand or at a predetermined time. The information provided may be filtered by the information provider and/or television receiver based on selected program categories and/or a user provided profile.
