Abstract
An video receiving apparatus which reduces waiting time till image is displayed on a monitor include: a plurality of authentication executing units which perform respectively an authentication process to the external devices connected to each of the plurality of input terminals; 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; an video receiving unit which receives the 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 a display control unit which outputs the received video information to a monitor.
Claims14
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.

A broadcast receiving apparatus comprising:
- a video receiving apparatus including:
- 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 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;
- a display control unit which outputs the video information received by the video receiving unit to a monitor;
- and
- a broadcast receiving unit which receives a television broadcast, wherein
- the broadcast receiving apparatus outputs at least one of video information received through the broadcast receiving unit or the video information input from the external devices through the input terminal selected as a video input terminal of the video receiving apparatus to the 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.
