Abstract:
There is provided an audio encoding device capable of effectively encoding a stereo audio even when a correlation between channels of the stereo audio is small. In the device, a monaural signal generation unit (110) generates a monaural signal by using a first channel signal and a second channel signal contained in the stereo signal. An encoding channel selection unit (120) selects one of the first channel signal and the second channel signal. An encoding unit including a monaural signal encoding unit (112), a first channel encoding unit (122), a second channel encoding unit (124), and a switching unit (126) encodes the generated monaural signal to obtain core-layer encoded data and encodes the selected channel signal to obtain extended layer encoded data corresponding to the core-layer encoded data.
Abstract:
The objective of the present invention is to provide a diversity receiver that detects differences in reception qualities for reception branches, and that controls the starting and halting of a diversity operation in accordance with the difference in the reception qualities, so that power saving is enabled and battery operating periods can be extended. A difference in reception levels (A, B) which are reception qualities for reception branches (13a, 13b), is employed to determine whether desired diversity effects are available or not. In a case wherein it is determined that desired diversity effects are not available, the diversity operation is halted and the supply of power to a reception branch that is not to be used is halted, and the combining operation is also halted.

This packet processing apparatus includes: a packet determination unit for determining whether a packet received by a receiver is a repetitive packet that has been repetitively transmitted by an information processing apparatus to a server apparatus; a transmission determination unit for determining whether the packet that is determined to be a repetitive packet should be transmitted; and a transmitter for transmitting a packet that is determined not to be a repetitive packet and a packet that is determined to be transmitted, and for not transmitting a packet that is determined, by the transmission determination unit, is not to be transmitted.
Abstract:
A zoom lens has a field view of 60° to 70° at a wide-angle end, a magnification change ratio of about five to six times, and a small number of component lenses, enables retraction to a compact size when not in use, provides high resolution, and is compatible with a compensation function for zoom lens vibrations. Comprised are, in order from an object side, a first lens unit (G1) of positive optical power, a second lens unit (G2) of negative optical power, a third lens unit (G3) of positive optical power, and a fourth lens unit (G4) of positive optical power. When zooming from the wide-angle end to a telephoto end, the first lens unit (G1) and the second lens unit (G2) move so as to trace a convex path toward an image side, and the third lens unit and the fourth lens unit (G4) move monotonously toward an object side.
Abstract:
A motor includes a stator with an annular stator yoke, a stator core having a plurality of inner and outer teeth projecting from the stator yoke toward inside and outside respectively, a plurality of coils wound on the stator core, and an inner rotor and an outer rotor confronting the inner and outer teeth respectively via an air-gap, and having an permanent magnet respectively. The number of slots “S” and the number of poles “P” establish a relation of S:P=3:2N−1, where N is an integer equal to 1 or more, and a case when 2N−1 becomes a multiple of 3 is excluded.

Abstract:
A program table generator 100 generates an electronic program table corresponding to multichannel broadcasting in which a plurality of programs are broadcast via one transponder by one broadcaster at the same time. The program table generator 100 includes: an information obtaining part 103 that obtains electronic program information relating to programs to be broadcast; a processing part 104 that determines, based on the electronic program information, whether or not the multichannel broadcasting is carried out, and that, when multichannel broadcasting is carried out, determines the number of non-display programs that are broadcast by the multichannel broadcasting but are not displayed on an electronic program table, and broadcast times of the non-display programs; and a program table generation part 108 that generates an electronic program table such that the number of the non-display programs and the broadcast times of the non-display programs determined by the processing part 104 are suggested.
