摘要:
An MXF parser thread 43 parses data MXF_D, being, mixed together, a plurality of video data PIC, a plurality of audio data SOU, and system data SYS. Then, it generates video file attribute data VFPD concerning the video based on the parsed system data and metadata META and generates video file data VF including the video file attribute data VFPD and the parsed plurality of video data PIC (VIDEO). Further, the audio file data AF is generated too in the same way.
摘要:
An information processing apparatus for processing an access request to access a recording medium from an application includes the following elements. A setting unit sets a priority unique to the access request from the application or permission information indicating whether or not processing on the access request from the application is permitted. A queue controller stores the access request provided with the priority or the permission information in a queue. An access request processor processes the access request stored in the queue according to the priority or the permission information.
摘要:
A program capable of individually decoding video data and audio data from data storing, mixed together, the video data, the audio data, and attribute data interleaved, wherein an SYS parse routine parses data MXF_D to extract system data SYS; a PIC parse routine parses the data MXF_D to extract video data PIC and decodes the related extracted video data PIC based on system data SYS extracted by the SYS parse routine 61, and an SOU parse routine parses the data MXF_D to extract audio data SOU and decodes the related extracted audio data SOU based on the system data SYS extracted by the SYS parse routine.

A railway vehicle operation-control system includes at least one central processing unit being connected to a plurality of devices, which are connected in parallel, via information communication means, the plurality of the devices having at least one operational state-monitoring function which transmits information on operational states of each device to the central processing unit; wherein a total controlled-variable necessary for the system is attained by allocating the total control variable to each device based on operational states determined from results of monitoring performed by the operational state-monitoring function, and a performance margin which is defined as a difference between a permissible power-output value and a current power-output value for each device while monitoring and reflecting the performance margin of each device.
摘要:
A semiconductor circuit or a semiconductor device has the current-voltage characteristic that, in a blocking-state of the semiconductor circuit or the semiconductor device, a current gently flows for values of a voltage equal to or greater than a first voltage value but equal to or smaller than a second voltage value, whereas a current abruptly flows for values of a voltage greater than the second voltage value. Due to the current-voltage characteristic, energy accumulated in an inductance provided within the circuit is consumed by a differential resistance of the semiconductor circuit or a semiconductor, thereby preventing the occurrence of the electromagnetic noise and an excessively large voltage.
摘要:
An inverter device includes plural modules, each module being formed by a series circuit having a parallel circuit of a first switching device and a first diode, and a parallel circuit of a second switching device and a second diode, allowing a reduced size, high reliability, high frequency switching and low noise. Each module forms one arm portion of the inverter. Lifetimes of the diodes and the switching devices are set in a manner to equalize losses in the inverter. Preferably, insulated gate bipolar transistors (IGBTs) formed by diffusion are used as the switching devices since the lifetimes of these devices can easily be adjusted to optimize design of the inverter.
