摘要： A television receiver according to the present invention successively transmits the same transmission command to external devices (1a)˜(3b) connected through IEEE (1394) lines and HDMI lines, and monitors the DC levels of HDMI terminals to which the respective HDMI lines are connected, thereby to discriminate the HDMI lines used for transmission of response commands that are outputted from the respective BD recorders (1b)˜(3b) in response to the transmission commands, and then automatically performs switching between the IEEE (1394) lines and the HDMI lines which are used by the respective BD recorders (1b)˜(3b), according to the operations of the BD recorders (1b)˜(3b). Therefore, with respect to the plural external devices which are connected to the television receiver through the HDMI lines and the IEEE (1394) lines, it is possible to automatically recognize as to which external devices are connected to which HDMI lines, whereby bothersome settings as those required in the conventional device are dispensed with, leading to enhanced user operability.
摘要翻译：根据本发明的电视接收机将相同的发送命令连续地发送到通过IEEE（1394）线路和HDMI线路连接的外部设备（1a）〜（3b），并监视HDMI端子的DC电平，线路被连接，从而根据传输命令来区分用于从各个BD记录器（1b）〜（3b）输出的响应命令的传输用的HDMI线，然后自动执行IEEE（1394 ）和根据BD记录器（1b）〜（3b）的操作由各个BD记录器（1b）〜（3b）使用的HDMI线。因此，对于通过HDMI线和IEEE（1394）线连接到电视接收机的多个外部设备，可以自动识别哪个外部设备连接到哪个HDMI线，由此令人不安的设置为省去了传统设备中需要的那些，从而增强了用户的可操作性。

摘要： On a display (100) end, maker codes and device codes are read from all STBs (110˜112) connected to the display (100) to create a connected-device table. When a user presses a button on a remote controller, the display receives a remote control code outputted from the remote controller, searches the connected-device table for a maker code and a device code that match the maker code and the device code included in the remote control code, controls a selector (105) so that a reception interface that is connected to an STB whose maker code and device code match those included in the remote control code is connected to a display section (102), thereby to display AV data transmitted from the STB on the display section (102).

摘要： A data transmitting and receiving method for improving transmission and reception efficiency can be obtained by improving the security through update of a control key and reduction of the frequency of the authentication and key exchange process. An STB 1 transmits encrypted digital data Kw (D) obtained by encrypting digital data D using a work key Kw, and an encrypted work key Kc (Kw) obtained by encrypting the Kw using a control key Kc. The Kc is periodically or non-periodically updated, and an identifier L identifying the Kc is assigned to each Kc. A VTR device 2 decrypts the received Kc (Kw) using the Kc obtained by performing the authentication and key exchange process with the STB 1, decrypts the Kw (D) received using the Kw to obtain the D. It is determined whether or not the Kc has been updated while the reception process is suspended by referring to the transmitted L when the reception process is suspended and then resumed. If it is determined that the Kc has been updated, then the authentication and key exchange process is performed again to obtain the updated Kc.
