Abstract:
1. A video receiving apparatus comprising: a plurality of input terminals, of which at least one complies with High-Definition Multimedia Interface (HDMI) standard; an authentication executing unit which performs an authentication process in High-bandwidth Digital Content Protection (HDCP) system to an external device connected to the at least one input terminal complying with the HDMI standard; a terminal selecting unit which selects one of the plurality of input terminals as a video input terminal based on an operation input from outside; a video receiving unit that judges whether the authentication process is completed, such that if the authentication process is judged complete, the video receiving unit receives video information through one of the authentication executing units corresponding to the selected input terminal from the external devices connected through the selected input terminal, and if the authentication process is judged incomplete, the video receiving unit waits until the authentication process is completed; and a display control unit which outputs the video information received by the video receiving unit to a monitor, wherein when an initial process of the authentication process is completed, the authentication executing unit holds a state where exchange of an authentication key is continuously preformed with the external devices, wherein the video receiving apparatus further comprises: a communication control portion which controls communication; and a connection judging unit which judges whether, or not, each of the plurality of input terminals is connected to the external devices, and wherein the authentication executing unit or authentication executing units that correspond(s) to the input terminal or input terminals judged to be connected with the external devices by the connection judging unit directly instructed by the communication control portion, perform(s) the authentication process to the connected external devices and then sends an instruction to the communication control portion.
