The problem to be solved is to make it possible to download via a network, efficiently manage, retrieve, and reproduce an external content associated with a content recorded on a recording medium. To solve the problem, a program is used which controls reproduction of information located on a recording medium and related information. The program includes the steps of: obtaining from the outside specific information associated with predetermined information recorded on a recording medium; and obtaining medium identification information located on a recording medium; wherein if the specific information has been obtained, a storage unit in a reproducing apparatus is controlled to associate the specific information with the medium identification information for storage.

In an apparatus not connected to a network can perform the reproduction within a valid viewing period. Also, in order to facilitate the change of the encryption algorithms of a password, a program recorded on the disk comprises the steps of acquiring a first medium identification number recorded on a recording medium, acquiring the current time, acquiring a password, calculating a second medium identification number and the expiry date of the valid viewing period from the password, comparing the first medium identification number with the second medium identification number, and comparing the current time with the expiry date of the valid viewing period. In the case where the first medium identification number coincides with the second medium identification number and the current time has not passed the expiry date of the valid viewing period, then the predetermined information is reproduced from the recording medium.
摘要:
A reproduction apparatus on which secondary video, which is displayed as a picture in picture video, is encoded in such a way that the secondary video information has an HD-size resolution as a video but its effective area is equal to or lower than a predetermined ratio of the whole size. This reproduction apparatus reduces the processing load at reproduction time, uses effective area information to determine the opacity level in combining the videos and, therefore, prevents primary video from being hidden by the secondary video in an area where the primary video should not be hidden.

A radio communications apparatus is disclosed which includes a generator which generates a transmit frame; and a transmitter which transmits the transmit frame via multiple transmit antennas. In the radio communications apparatus, the transmit frame includes a predetermined number of resource elements having a predetermined frequency bandwidth and a predetermined symbol period, and the generator generates the transmit frame such that the number of transmit antennas which are identifiable from a location of the resource element taken up by a pilot signal in a certain transmit frame is less than the number of transmit antennas which are identifiable from the location of the resource element taken up by the pilot signal in a retransmission transmit frame of the certain transmit frame.

On a single chip are formed a plurality of magnetoresistance effect elements provided with pinned layers having fixed magnetization axes in the directions that cross each other. On a substrate 10 are formed magnetic layers that will become two magnetic tunnel effect elements 11, 21 as magnetoresistance effect elements. Magnetic-field-applying magnetic layers made of NiCo are formed to sandwich the magnetic layers in plan view. A magnetic field is applied to the magnetic-field-applying magnetic layers. The magnetic field is removed after the magnetic-field-applying magnetic layers are magnetized in the direction shown by arrow A. As a result of this, by the residual magnetization of the magnetic-field-applying magnetic layers, magnetic fields in the directions shown by arrows B are applied to the magnetic layers that will become magnetic tunnel effect elements 11, 21, whereby the magnetization of the pinned layers of the magnetic layers that will become magnetic tunnel effect elements 11, 21 is pinned in the directions shown by arrows B.
摘要:
A recording medium playback device, by which the number of parts can be prevented from increasing and a size of the device can be prevented from being enlarged, is provided. A CD changer includes a disk receiving part, disk carrying part, positioning part, motor, and transmission restricting part 74. The disk receiving part has a plurality of holders each for holding a CD. A plurality of the holders are arranged being piled on one another and movable along the arranging direction. The disk carrying part carries the CD. The positioning part moves the disk receiving part along the arranging direction. The motor supplies drive force to both the disk carrying part and the positioning part. The transmission restricting part 74 restricts the drive force of the motor to be transmitted to the positioning part when the disk carrying part carries the CD.
