Abstract: According to one embodiment, a stereoscopic image reproduction apparatus is configured to output a video signal on which signal processing corresponding to stereoscopic image display has been performed, when stereoscopic viewing glasses are being worn, and configured to perform one of outputting a video signal on which signal processing corresponding to two-dimensional image display has been performed, instead of the signal on which the signal processing corresponding to stereoscopic image display has been performed, and stopping outputting of the video signal on which the signal processing corresponding to stereoscopic image display has been performed, when stereoscopic viewing glasses are not being worn.

Abstract: According to one embodiment, the information processing apparatus comprises a compression control unit which performs compression processing on a data payload added to a packet output from a transaction layer of a first device and supplies the compressed data payload to a data link layer of the first device, and a decompression control unit which performs decompression processing on a compressed data payload added to a packet received by a data link layer of a second device and supplies the decompressed data payload to a transaction layer of the second device.

Abstract: According to one embodiment, a communication system with a transmitting device and a receiving device communicably connected thereto, wherein the transmitting device comprises a packet transmitting unit to transmit a data packet to the receiving device and a retransmission buffer which stores the data packet for a retransmission and the receiving device comprises a validity determining unit which receives the data packet from the transmitting device to determine validity of the data packet and an acknowledgement transmitting unit which transmits a positive acknowledgement showing that the data packet is approved or a negative acknowledgement showing that the data packet is not approved at prescribed intervals on the basis of the determination result from the validity determining unit. The communication system further comprises an adjusting mechanism which adjusts a size of the retransmission buffer and a timing of the transmission of the acknowledgement to the data packet from the transmitting device.

Abstract: In a flow control initialization method and an information processing apparatus, a first component enters a first initialization mode and sends a first first-component initial value to a second component. Subsequently, upon receipt of a first second-component initial value or a second second-component initial value from the second component, the first component enters a second initialization mode and sends a second first-component initial value to the second component. Upon receipt of the second second-component initial value, a second-component flow control value, or a transaction layer packet from the second component, the first component completes the initialization process, and then sends at least one of a first-component flow control value and a transaction layer packet to the second component at least one time.

Abstract: According to one embodiment, a state shift of a state machine is stored in BIOS-ROM as history information and a state of the state machine is controlled by CPU to be shifted to a specific state or not to be shifted thereto, in accordance with the history information.

Abstract: A receiver including: a receive buffer; a first buffer controller for deciding an initial value of capacity allocated to the receive buffer in accordance with each data type and updating the initial value of the allocated capacity in accordance with opening of the receive buffer; and a second buffer controller for dynamically updating either of the initial value of the allocated capacity and the allocated capacity after updating.

Abstract: A security process setup module sets security processes of important data upon occurrence of emergency situations for respective data and respective types of emergency situations, and stores the setup contents in a security process setup table. An emergency situation detection module monitors signals from a LAN and the Internet. Upon detection of occurrence of any emergency situation based on any received signal, the module advises a security process execution module accordingly. Upon reception of this advice, the security process execution module executes the security processes of important data for respective data and the respective types of emergency situations on the basis of the security process setup table.

Abstract: In a rotary compressor, a roller (6) fitted around an eccentric portion (51) of a drive shaft (5) is provided in a cylinder chamber- (21) of a cylinder (2) in such a way that the roller (6) is revolvable around the drive shaft (5). A blade (61) provided integrally with and protruding from the roller (6) is swingably supported by a support member (62) rotatably provided in the cylinder (2). An oil groove (64) opened at axial end faces of the roller (6) is formed on the inner peripheral surface of the roller (6) on a counter loaded side and within a range from a position where the blade (61) is protrusively provided, to another position 180 degrees displaced therefrom in the rotating direction of the drive shaft (5), whereby oil can be positively fed from the oil groove (64) to sliding surfaces.
