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.

Claims

1. A video receiving apparatus equipped with a plurality of input terminals and configured to output video information input from a plurality of external devices through each of the plurality of input terminals to a monitor, the video receiving apparatus comprising:

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 video information received by the video receiving unit to the monitor.

2. The video receiving apparatus according to claim 1, wherein the input terminals are input terminals according to High-Definition Multimedia Interface (HDMI) standard.

3. The video receiving apparatus according to claim 1, wherein the authentication executing units perform the authentication process in High-bandwidth Digital Content Protection (HDCP) system.

4. The video receiving apparatus according to claim 2, wherein the authentication executing units perform the authentication process in High-bandwidth Digital Content Protection (HDCP) system.

5. The video receiving apparatus according to claim 1, further comprising a connection judging unit which judges whether, or not, each of the plurality of input terminals is connected to the external devices, 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, perform(s) the authentication process to the connected external devices.

6. The video receiving apparatus according to claim 2, further comprising a connection judging unit which judges whether, or not, each of the plurality of input terminals is connected to the external devices, 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, perform(s) the authentication process to the connected external devices.

7. The video receiving apparatus according to claim 3, further comprising a connection judging unit which judges whether, or not, each of the plurality of input terminals is connected to the external devices, 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, perform(s) the authentication process to the connected external devices.

8.
