摘要： In a method of reproducing information from an optical disk, the disk is scanned with a laser beam forming a light spot on the disk, at least some of the recording pits being smaller in size than the light spot, the laser beam heating the disk so that effective detection area being formed at only part of the light spot, a sequence of preformatted pits of a minimum size are formed, playback signals are produced in accordance with a reflected light from the disk, and a power of the laser beam is so controlled so as to maximize the level of the playback signals produced from the reflected light from the sequence of pits of the minimum size. In another method using a magneto-optical disk, information is recorded by scanning the disk with a laser beam, each of the recording pits being substantially crescent-shaped, the direction of rotation during playback is opposite to the direction of rotation during playback, and the order of bits forming the information is reversed either during the playback or recording.

摘要： Provided is a gateway device for interconnecting an IEEE1394 network and an IP network, which automatically detects and operates an AV device connected to the IEEE1394 network from a player device connected to the IP network, thereby enabling the player device to watch and hear contents stored in the AV device. The gateway device interconnects a network, to which an AV/C installed IEEE1394 device is connected, and a network, to which a player device compliant with a UPnP is connected, and includes: a conversion unit for converting Plug-and-Play processing of the IEEE1394 device to each step of Plug-and-Play of the UPnP; a conversion unit for converting an action of a UPnP AV to an AV/C command of the IEEE1394 device; and a stream transfer unit for transferring stream data transmitted from the IEEE1394 device to the IP network.

摘要： An apparatus has not been configured without accompanying entirely changing and revising the system LSI when the specification of the apparatus or the system LSI configuring the apparatus is changed, and also, development cost has not been able to be reduced and development period has not been able to be shortened. An image information apparatus is realized in which new functions are easy to be added into the image information apparatus without need for development of a new system LSI for each model, by installing into the image information apparatus a ubiquitous image module having configurational elements such as a hardware engine, CPU, and general-purpose bus for realizing functions that have not been provided on the image information apparatus itself, and also including an OS for operating the configurational elements.
