Abstract: An electromagnetic field band-stop filter includes a plurality of unit structures that have reflection characteristics on an electromagnetic wave of a predetermined frequency. Each of the plurality of unit structures includes: a plurality of electrode parts each of which is disposed along a side of a polygon in a non-contact manner with another electrode part; and a plurality of conductor parts which are provided for the plurality of electrode parts on a one-to-one basis and each of which has at least one bent portion between one end and other end, the one ends of the plurality of conductor parts being connected to the electrode parts on a one-to-one basis and the other ends of the plurality of conductor parts being connected at one point on an inner side of the electrode parts in the individual unit structure.

Abstract: A frequency selective surface having a steep attenuation slope (high sharpness) characteristic is provided without decreasing the line width of a conductive pattern nor the pattern interval thereof. In a frequency selective surface having a structure in which resonators k1xy having identical shapes are periodically arrayed on a dielectric substrate 101, each resonator k1xy includes a cross-shaped conductive pattern formed on the dielectric substrate 101 and a lateral pattern 10 and a longitudinal pattern 20 forming a cross are shaped such that each pattern is extended by a predetermined length in respective directions, each pattern extended by the predetermined length is further extended in both directions orthogonal to each other on the dielectric substrate 101, and leading end parts of the respective further extensions face each other at a predetermined interval d.

Abstract: Provided is a display method which can avoid the load increase and display rapidly the video of the selected channel. The display method includes adjusting a timing, in which a video is displayed based on a predetermined reference frame received and decoded at first after channel selection, toward shifting earlier than a time originally displaying the video based on a time information attached to the reference frame.

Abstract: A mobile terminal 10, which includes a TV receiver to receive a broadcast of a TV program and which is provided with the function of recording and pre-programming a received TV program, uses the detection parts (151, 152, 153) to detect the occurrence of an event which will preclude the operation of the TV program recording function, and uses the message transmission/reception part 155 to instruct the recording or pre-programming of an in-recording or pre-programmed TV program, based on an instruction from the event occurrence detection part 154, to a server device 20 or a video recorder 30, which is an external recording device having the TV program recording function and connected with the mobile terminal via a communication line (50).

Abstract: High-quality digital content to which a copy control signal of “copy one generation” is added can be carried with a portable terminal. Original digital content in a recording device can be retained with the quality kept unchanged. A picture record data control device 101a converts picture record data stored in a picture record data memory device 101c in format and writes the converted picture record data into a removable medium 102. Then, the picture record data control device 101a updates output status information 24 in a picture record information table 101b into “outputted” so as to prohibit any operation to the picture record data. Further, when a removable medium 102 is newly inserted into a removable medium device 101e, the picture record data control device 101a updates the output status information 24 in the picture record information table 101b that corresponds to picture record data deleted from the removable medium 102 so as to permit operation of the picture record data.

Abstract: The decoder for decoding the encoded audio data comprises an error detection device for detecting errors of encoded audio data; an error concealing method determining device for determining an audio frame and weight of window function which are used for concealing the errors based on error information detected by the error detection device; a frequency-to-time converter for converting audio data of frequency components to time-component audio frame; an audio frame buffer for accumulating the time-component audio frame outputted by the frequency-to-time converter; and a windowing processing device for adding weight onto the time-component audio frame outputted by the frequency-to-time converter and/or the audio frame accumulated in the audio frame buffer according to the weight of window function determined by the error concealing method determining device.

Abstract: A synchronization system and method for databases by which the immediacy of synchronization between the databases can be assured without dialup connection and the power supply to an information terminal need not always be on to keep the information terminal in a standby state is disclosed. The database synchronization system synchronizes data of databases of an application server and an information terminal connected to each other through a network. A first database information update notification section provided in the application server extracts only differential information of the database of the application server and issues a notification of the differential information to the information terminal. A second database information update notification section provided in the information terminal extracts only differential information of the database of the information terminal and issues a notification of the differential information to the application server.
