One aspect of the present invention discloses an apparatus for detecting additional data for preventing forgery of video data and displaying the video content. The apparatus includes a content input unit configured to receive the video content (the video content including the additional data), a display unit configured to display the video content, an additional data detector configured to detect the additional data from the video content (the additional data including a watermark), and a display controller configured to control a display screen of the video content according to an additional data detection result.

In an embodiment, an electronic device may be configured to capture still frames during video capture but may capture the still frames in the 43 aspect ratio and at higher resolution than the 169 aspect ratio video frames. The device may interleave high resolution, 43 frames and lower resolution 169 frames in the video sequence, and may capture the nearest higher resolution, 43 frame when the user indicates the capture of a still frame. Alternatively, the device may display 169 frames in the video sequence, and then expand to 43 frames when a shutter button is pressed. The device may capture the still frame and return to the 169 video frames responsive to a release of the shutter button.

Transmission of HDR image data is satisfactorily performed between apparatuses.

A transmission apparatus (synchronized apparatus) transmits the HDR image data to a reception apparatus (source apparatus) over a transmission path. At that time, the transmission apparatus transmits information on a transmission method for and/or information on gamma correction for the HDR image data to the reception apparatus over the transmission path. The reception apparatus performs processing (decoding processing, gamma correction processing, and the like) on the received HDR image data, based on the information on the transmission method and/or the information on the gamma correction that are received. For example, the transmission apparatus receives from the reception apparatus the pieces of information on the transmission method and/or the gamma correction that the reception apparatus can support, selects the method that the reception apparatus can support, and thus uses the selected method.

There is provided an information processing device, an information processing method, and a program that make it possible to decrease reduction in a recognition rate corresponding to the amount of exercise of a user wearing a wearable device. Acceleration information is acquired as exercise state information, and movement speed is calculated. If the movement speed exceeds certain speed, a plurality of pieces of information is displayed in a time-division manner for a certain amount of information each with which amount a recognition rate is not decreased, whereby a plurality of pieces of information is displayed while reduction in the recognition rate is controlled. The present technology can be applied to a wearable device.

A technology of preventing feeling of a viewer on brightness from significantly changing when content is switched is provided. A video display device (1) includes a calculation unit (23) that calculates video feature relating to a display video, and a mute video display unit that displays a mute video posterior to a first display video, in which luminance of the mute video is luminance corresponding to a value of the video feature relating to the first display video.
