The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is open to a user, the received data is deciphered by a 1394 interface. In contrast, in the personal computer with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key by a 1394 interface, and a result of the decipherment is further deciphered using a session key by an application section.

The present invention relates to proteins which have a role in controlling neuronal cell migration and cell death as well as to the DNA which encode those proteins. It is an object of the present invention to provide control of cell migration and/or cell death by providing a method for screening for promoters or inhibitors of proteins which affect the control of cell migration and/or cell death of neurons by interacting with an actin-binding protein, Filamin 1, through promoting the degradation of Filamin 1 or the DNA encoding Filamin 1. The cDNAs of S-FILIP, L-FILIP and h-FILIP cDNAs, which interact with Filamin 1, thereby negatively affecting cell migration and cell death by promoting the degradation of the Filamin 1, were isolated and the full nucleotide and amino acid sequences thereof were determined.

A DTV operating screen is displayed on the CRT display screen of a DTV which is the controlling apparatus of a network. In the event that the user selects the DVHS from the buttons displayed on the DTV operating screen, data corresponding to the DVHS operation screen is input to the DTV, and a DVHS operation screen is displayed on the CRT display screen 61. The user operation executed regarding the DVHS operation screen are notified from the DTV to the DVHS, so the DTV can execute control corresponding to the operations of the user, without transmitting commands for directly controlling the DVHS.

A pickup device which, focusing a ray bundle on a track of a recording surface of an optical recording medium to form a light spot, comprises a detection optical system including a photo detector to receive return light reflected from the light spot via an objective lens and perform photoelectric conversion. The photo detector has at least two photoreceptor sections positioned axis-symmetrical with respect to a detection-side division line extending through an optical axis of the return light and parallel to the track. A dividing element placed in an optical path between the photo detector and the objective lens includes at least two inner divided areas positioned axis-symmetrical with respect to a deflection-side division line extending through the optical axis of the return light and parallel to the track, and at least two outer divided areas positioned sandwiching the inner divided areas and axis-symmetrical with respect to the deflection-side division line. The inner divided areas are formed such that parts of a light beam from the other region than overlap regions, divided axis-symmetrically along the deflection-side division line, are exchanged in position across the detection-side division line and directed to the photoreceptor sections of the photo detector so as to be axis-symmetrical with respect to the detection-side division line.

The present invention provides a portable electronic device including an operator block, a display block, detection means, and control means. The operation block has a plurality of operation buttons arranged in matrix. The display block, arranged in the vicinity of the operator block, is capable of displaying a screen divided into a plurality of areas corresponding to the arrangement of the plurality of operation buttons, displaying a cursor for selecting each the areas, and entering the selection by operation of each of the operation buttons. The detection means detects whether any one of the plurality of operation buttons has been operated. The control means positions the cursor to the area corresponding to the detected operation button and displays the cursor on the display block.

The present invention relates to a communications apparatus and method, a storage medium and a program that make it possible for the user to select a device to be made a communications partner more quickly and reliably. The searcher device 21 performs a search so as to detect only one device. If the response message from the searchee device 32 is obtained by the searcher device 21, on the display section of the searcher device 21 is displayed a selection screen for selecting whether or not to make the searchee device 32 a communications partner. If the searchee device 32 is not selected as a communications partner, the searcher device 21 performs another search so as to detect two devices. If the searchee device 31 and the searchee device 32 are detected in the second search, the searcher device 21 excludes the searchee device 32, which was not selected as a communications partner in the previous search, and displays a selection screen for selecting whether or not to perform communications with the searchee device 31. The present invention is applicable to various kinds of communications apparatuses, such as personal computers, PDAs, mobile phones and the like.
