摘要:
The present invention relates to system and method of reading and rewriting EDID in a video transmission system includes a transmitter transmitting a video signal and a receiver receiving the video signal that the transmitter transmitted which are connected to each other through digital interface, the method includes a reading step where the transmitter reads the EDID of the receiver through the digital interface; a first transmitting step where the transmitter transmit the video signal to the receiver on the basis of the EDID which the transmitter read; a second transmitting step where the receiver transmits a first message related to the EDID of the receiver; and a third transmitting step where the receiver transmits a second message related to the EDID of the receiver; wherein the transmitter, which received the first message from the receiver, does not read the EDID of the receiver until the second message is received.

The present invention provides a data reading method, and a video transmitter and a video receiver using the same in which there is no video interruption time or a video interruption time is short during rewriting of EDID.In a video transmitter which transmits a digital video signal obtained by performing a contents protection process to a video receiver through digital interfaces, after the video transmitter reads information related to the characteristics of the video receiver and performs a default setting of a video signal format on the basis of the information by a default setting process to be executed when power is started to be supplied from the video transmitter to the video receiver, the video transmitter performs a CP process and transmits a digital video signal. During transmission of the video signal, when receiving a re-reading request for the information related to the characteristics of the video receiver transmitted from the video receiver through a bidirectional communication line, the information related to the characteristics of the video receiver is read through the bidirectional communication line or another bidirectional communication line, and the video signal generated by resetting the video signal format on the basis of the read data is transmitted to the video receiver.

The objective of the present invention is to provide a charged particle beam device such that a tip part can be effectually maintained in a clean state, while the frequency of valve body replacements is also reduced. To achieve the objective, a charged particle beam device is offered, comprising: a partition that is positioned between a charged particle source-side vacuum space and a specimen stage-side vacuum space, said partition further comprising an opening for a charged particle beam to pass through; a driver mechanism that moves a shutter member between a first location within the optical axis of the charged particle beam and a second location outside the optical axis of the charged particle beam; and a control device that controls the driver mechanism. The first location is a location wherein the shutter member is distanced from the partition, and the control device carries out a control that opens a valve between the specimen chamber and the exchange chamber when the shutter member is in a state of being located in the first location.
