摘要： PROBLEM TO BE SOLVED: To provide a protocol/function (secure maintaining method) with which even in a state where a drive device and a host device are combined, secure can be maintained and equipment-specific private shared value can be written/securely written. SOLUTION: By using one embodiment of the present invention, a drive device 21 and a host device 11 are combined and writing work of key information [Kdevice] is then performed. Thus, in a player (an assembled player) 1, it is not necessary to manage the correspondence of private key information between the host device and the drive device. Furthermore, even if a drive device is exchanged, for example, in the player, only by writing other key information[Kdevice] data again, cryptographic key data can be shared.

摘要： PROBLEM TO BE SOLVED: To realize an accurate data relay between a source equipment and a display unit. SOLUTION: A repeater 19 is comprised of an EDID memory 27 for storing control data and memory control units 91, 93. The memory control units 91, 93 read an access control data in an EDID memory 8 and store the read control data in the EDID memory 27. The memory control units 91, 93 transmit the control data stored in the EDID memory 27 to a set top box 1, when the EDID memory 27 is accessed by the set top box 1. In this case, the memory control units 91, 93 output a forbidden signal to the set top box 1, until an operation to store the control data, from the EDID memory 8 to the EDID memory 27 is completed, and inhibit the EDID memory 27 from accessing.

摘要： PROBLEM TO BE SOLVED: To provide 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.
SOLUTION: 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 about the characteristics of the video receiver and performs initial setting of a video signal format on the basis of the information by an initial setting process to be executed when power supply is started from the video transmitter to the video receiver, the video transmitter performs a CP process and transmits a digital video signal thereafter. During transmission of the video signal, when receiving a re-reading request for the information about the characteristics of the video receiver transmitted from the video receiver through a bidirectional communication line, the information about the characteristics of the video receiver is read through the bidirectional communication line or another bidirectional communication line, and the video signal obtained by resetting the video signal format on the basis of the read data is transmitted to the video receiver.
