A control signal transmission circuit and a control signal receiving circuit for an audio/video interface are provided. The control signal transmission circuit includes an audio/video interface encoder, a signal packaging circuit and a data allocator. The audio/video interface encoder is configured to receive an audio packet and supports a user-defined packet format. The signal packaging circuit is configured to receive a first control signal and package the first control signal into a control data packet according to the user-defined packet format. The data allocator is configured to receive a video data and a second control signal and to mix the second control signal and the video data to generate a mixed data packet. The audio/video interface encoder packages the control data packet, the mixed data packet and the audio packet according to an audio/video transmission protocol to generate an audio/video and control data.

An information processing method. The information processing method includes obtaining an input operation, the input operation being used to activate an input interface; and activating the input interface and displaying the input interface in an output area of a display screen based on a refresh rate corresponding to the input interface in response to the input operation.

An enhanced video book and a system and method for creating an enhanced video book are described. Artwork and text corresponding to a storyline can be converted into a format that can be animated. A timing is established at which the converted artwork can be displayed, at a pace corresponding to the timing at which the converted text can be read. The converted artwork and/or the converted text are animating, and voice-over narration corresponding to the converted text is generated. The display of the converted artwork or the converted text is adjusted and synchronized with the voice-over narration based on the timing at which the converted artwork can be displayed. Audio is added and synchronized to the converted artwork. The converted artwork, the converted text, the animated or converted artwork, the animated converted text, the voice-over narration, and the audio are combined into an enhanced video book.

A display apparatus includes circuitry to display, on a display, an image including a table, receive an operation of specifying a range to be edited in the image, acquire coordinates of lines of the table in the range, and change a color of pixels other than pixels corresponding to the lines in the range to a predetermined color.

A display system includes a host and a display. The host executes a first application and a program. The program sets a first display parameter corresponding to the first application. The display receives a signal provided by the host. The signal includes a desktop image. The first application is operated at a first window on the desktop image. The program outputs the first display parameter to the display. The display sets the first window with the first display parameter and displays, and displays the non-first window area of the desktop image with a preset display parameter.

A sewing apparatus, includes a display input unit including a display unit configured to display an image of an input screen, and an input detection unit configured to detect an input operation on the input screen; and a control apparatus that performs display control of the display unit in response to the input operation. The control apparatus performs display control in which a background of the input screen is set to a dark color as a whole, a sewing pattern image displayed on the input screen is set to brightness higher than that of the background, and an operation unit that receives the input operation on the input screen is set to a color lighter than that of the background.

An information processing method. The information processing method includes obtaining an input operation, the input operation being used to activate an input interface; and activating the input interface and displaying the input interface in an output area of a display screen based on a refresh rate corresponding to the input interface in response to the input operation.

An embodiment for adjusting digital content in a flexible display device is provided. The embodiment may include receiving data relating to a position and orientation of a reference device relative to a user. The embodiment may also include identifying an orientation of a display surface of a mobile device and a relative position of the mobile device relative to a viewing direction of the user. The embodiment may further include identifying an optimal viewing angle of display content on the display surface of the mobile device. The embodiment may also include in response to determining the display content is not able to be displayed as a hologram, aligning the display content as text based on the optimal viewing angle. The embodiment may further include presenting the aligned display content as text to the user.
