Wireless communication apparatus, wireless communication method, and computer program

Abstract: A wireless communication apparatus that includes a first format detecting unit detecting a format by executing signal processing on a preamble of a received packet before decoding, an estimating unit using the preamble to carry out multiple types of estimations, and a decoding unit decoding the received packet in accordance with the detected format based on the estimations. The apparatus further includes a second format detecting unit detecting the format of the received packet based on decoded control information in the preamble of the received packet, an error detection determination unit, when the format detected by the first format detecting unit differs from the format detected by the second format detecting unit, determining that the format detected by the first format detecting unit is an error, and a control unit controlling operations of the estimating unit and the decoding unit based on a determined result.

Window system preventing overlap of multiple always-visible windows

Abstract: A method and apparatus for establishing an always-visible class of windows in a computer-implemented windowing environment is provided. A user may designate one or more windows as always-visible windows. If an always-visible window overlaps with a non-always-visible window, then the always-visible window is displayed on top of the non-always-visible window. Always-visible windows are prevented from overlapping with each other. Techniques are provided for implementing the always-visible window class in a manner that complies with the X Windows system. According to one technique, the override redirect attribute is used as a flag to designate which windows are always-visible windows. According to an alternative technique, a list of always-visible windows is maintained as a property attached to a root window.

Display device, display method, and program

Abstract: A display device that is capable of displaying predetermined display information in each of a plurality of display areas includes a setting unit for setting display control information that represents the position and size of the display area and the switching of the display information for which a predetermined event is detected, based on user inputs; and a display control unit for controlling one display including the multiple display areas such that the display information is displayed in each of the multiple display areas, based on the display control information set by the setting unit. Upon detection of the event, the display control unit switches the position or size of the display area where the display information for which the event is detected is displayed based on the display control information.

Recording and playback apparatus and method, terminal device, transmitting/receiving method, and storage medium

Abstract: A method and apparatus to enable a user to easily make a search with respect to a large amount of music data copied and stored from CDs in a built-in recording medium. A music server is able to record a large amount of music data played back from CDs in a built-in hard disk drive (HDD). When recording the music data, table of contents (TOC) information of each CD is read out of the CD and recorded in the HDD, and simultaneously sent to a personal computer via a connecting line. A CD album information database is provided in the form of a CD-ROM to the personal computer. In the personal computer, which one of CDs recorded in the database on the CD-ROM corresponds to the relevant CD is searched based on the total playing time and the time information of each track which are contained in the TOC information sent to the personal computer. A search result is sent back to the music server. The music server records the CD album information in the HDD in the form of a management database in correlation to the TOC information so that the CD album information can be displayed or a music CD to be played back can be selected based on the CD album information.

Information processing apparatus, information processing method and recording medium

Abstract: Encoding parameters of picture and higher layers of importance to a number of applications, and encoding parameters of slice and lower layers of no importance to all applications are converted into auxiliary packets inserted respectively into a V-blanking area and an H-blanking area of a video-data signal output by a history-information-multiplexing apparatus employed in a video-decoding system. On the other hand, a video-encoding system extracts back the auxiliary packets superposed on the V-blanking area and the H-blanking area from an input base-band video signal. As a result, a technique of superposing information on data can be changed in accordance with the importance of the information and required information can be fetched with ease.
