Embodiment Construction
[0059] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0060] figure 1 An example of the system configuration of the image-linked control target external device control device of the present invention is omitted. The image-linked control target external device control device 60 uses the expanded image data as a source of image (animation) data. The expanded image data is used to output the first image (animation) data of the image signal of the main image. The output information is incorporated into the second image data of the mark image video signal, and the information incorporated into the mark image video signal reflects the content of the control information used in the operation control of the control target external device. Furthermore, a video (animation) reproducing device 61 for reproducing expanded video (animation) data and a control target external device 62 are connected to it. In this embodiment, an output mon...

First video data is used for outputting a video signal of a main image. Second video data is used for outputting a video signal of an information incorporation mark image (4) reflecting control information contents used for controlling the operation of a controlled object external device (62). Expansion video data including the first video data and second video data is recorded in a video recording medium (61M). An external device controller (60) of the present invention separates the expansion video signal generated by reproducing the expansion video signal into a main image reproduction video signal based on the first video data and information incorporation mark image reproduction video signal based on the second video data. The separated information incorporation mark image reproduction video signal is decoded into operation control data directly readable by the controlled object external device (62) and outputted to the controlled object external device (62). With this, in the field of the video application technology using recording media, information relevant to a video can be outputted to an electronic device outside a video player system, and the function expansion including anticipation of link control of the electronic device can be realized. Thus, such video incorporation controlled object external device controller is provided.
Description
Technical field [0001] The present invention relates to an image-linked control target external device control device and an image storage medium used in it. Background technique [0002] Patent Document 1: Japanese Patent Application Publication No. 10-164524 [0003] In recent years, multiple communication technologies are also being applied to television broadcasting, and have been developed into practical applications in voice multiple broadcasting, text multiple broadcasting, and so on. However, any audio frequency band and text frequency band are set separately from the video frequency band, so additional information such as speech and text cannot be embedded in the video transmission image. Therefore, in order to solve this problem, Patent Document 1 discloses a technique of embedding additional information in the form of a bar code in a part of the scanning line of the transmitted image of the image. Specifically, the detailed information of the CM product or the program ...
