Description

  The present invention relates to a content display device and a content display method, and in particular, a content display device and a content display suitable for displaying content displayed by the mobile phone on an in-vehicle display unit in a state where the mobile phone is connected. Regarding the method.

  In recent years, against the background of diversification of user needs for in-vehicle devices, various techniques for improving usability of in-vehicle devices by strengthening cooperation with external devices of in-vehicle devices have been proposed.

  As an example, after connecting a mobile phone (external device) having a normal telephone function such as a smartphone (registered trademark) and various content playback functions to an in-vehicle device using a connection method such as USB connection, A technique for outputting content played back on the mobile phone on the in-vehicle device side is known.

  In such a technique, when the content is a video, the content displayed on the display unit of the mobile phone is displayed on the display unit of the in-vehicle device as it is.

  In a mobile phone applied to this kind of technology, a navigation screen such as a map screen or a guidance screen in navigation can be displayed as content (see, for example, Patent Document 1). If displayed on the machine side, it was possible to use the content unique to the vehicle-mounted device in the original usage mode using the vehicle-mounted device.

The content storage processing unit 14 is a predetermined content that should be continuously displayed on the display unit 1a even when the content acquired by the content acquisition unit 11 is interrupted from acquisition of the content from the mobile phone 3. In the case of (hereinafter referred to as continuous display target content), the continuous display target content is stored in the content storage unit 15. Note that whether or not the content acquired by the content acquisition unit 11 is the content to be continuously displayed may be determined based on additional information associated with the video data acquired together with the video data of the content.

  Then, the content display processing unit 12 displays the content when a predetermined event that interrupts (stops) acquisition of the content from the mobile phone 3 occurs while the continuous display target content is being displayed. The content stored in the storage unit 15 is continuously displayed for a period from when the event occurs until a predetermined condition is satisfied. As a result, the content to be continuously displayed, which is obtained from the mobile phone 3 side and has high utility value on the in-vehicle device 7 side, is displayed on the in-vehicle device 7 side as long as possible regardless of the operation status of the mobile phone 3. Therefore, the convenience of the in-vehicle device 7 can be improved.

  Here, the predetermined event may include an incoming call to the mobile phone 3. The incoming call may be detected, for example, by the content acquisition unit 11 acquiring the mobile phone incoming call screen or the additional information indicating the incoming call. Then, when an incoming call is received while the continuous display target content is being displayed, the content display processing unit 12 replaces the display of the incoming call screen acquired by the content acquisition unit 11 with the incoming call, and the content storage unit 15 What is necessary is just to perform the continuous display of the continuous display object content read out from. As a result, an appropriate event can be selected as one of the predetermined events, so that convenience can be improved with certainty.

  In addition, when such continuous display target content is continuously displayed, the content display processing unit 12 may display simple information for notifying incoming calls on the continuous display target content screen. . Accordingly, it is possible to notify the user that there is an incoming call while maintaining the display of the content to be continuously displayed, and the convenience can be further improved.

You may display on the display part 1a. The information may be displayed on the screen of another content displayed on the display unit 1a immediately after the continuous display of the content to be continuously displayed is finished. Thereby, since the user can surely grasp that the continuous display content is invalidated, the user's confusion due to the end of the display of the content can be alleviated.

  Further, the content storage processing unit 14 may store only the latest screen of the continuous display target content in the content storage unit 15. Here, the latest screen of the content to be continuously displayed changes sequentially with the stream transfer of the video data of the screen from the mobile phone 3. Therefore, the content storage processing unit 14 stores the current latest screen in the content storage unit 15 in order to store only the latest screen of the continuous display target content in the content storage unit 15. What is necessary is just to delete the latest past screen which was preserve | saved from the content memory | storage part 15. FIG. However, this deletion includes overwriting. As a result, since the screen displayed on the in-vehicle device 7 side when the predetermined event occurs can be displayed as it is, it is possible to reduce the uncomfortable feeling given to the user, and the capacity of the content storage unit 15 Therefore, the cost can be reduced.

  According to the present embodiment, for example, as shown in FIG. 3A, the same navigation screen 2 is displayed on the display unit 1a of the in-vehicle device 7 and the display unit 3a of the mobile phone 3 connected to the in-vehicle device 7. When the mobile phone 3 receives an incoming call, the incoming call screen 4 is prioritized on the mobile phone 3 side as shown in FIG. The navigation screen 2 that has been used can be held. In FIG. 3B, the simple information for notifying the incoming call is displayed as an overlay, but the display of such simple information is handled as not hindering the holding of the navigation screen 2.

  Next, as an example of a content display method according to the present invention, an embodiment of a content display method to which the above-described content display system 8 is applied will be described with reference to FIG.
