    Abstract: Various methods, systems, and electronic devices include delivery of sequential subtitle images to a client device. To that end, a method includes obtaining a plurality of sequential subtitle images including a first sequential subtitle image and a second sequential subtitle image. The method includes generating a diff image by comparing the first sequential subtitle image against the second sequential subtitle image. The diff image includes content that is absent from the first sequential subtitle image and present in the second sequential subtitle image. The method includes sending, to the client device, the diff image and display metadata associated with the diff image. The metadata may include a temporal indicator that indicates a display time or display duration of the diff image, and may include a position indicator that indicates a display position of the diff image.

    Abstract: A video content distribution system including a user terminal on which contents are viewable and a content management server. The user terminal includes a first reception unit configured to receive field-of-view video data. The user terminal includes a display control unit configured to display a field-of-view video. The user terminal includes a viewpoint switch request signal generating unit for requesting a switch from a first viewpoint to a second viewpoint in the field-of-view video. The user terminal includes a first transmission unit configured to transmit the viewpoint switch request signal to the content management server. The content management server includes a second reception unit configured to receive the viewpoint switch request signal. The content management server includes a second transmission unit configured to transmit the field-of-view video data. The content management server further includes a switch count updating unit configured to update a count of switches to the second viewpoint.

    Abstract: Information bits may be superimposed onto a transmitted image while reducing or minimizing the effects of the superimposed information bits on the transmitted image signal's frequency spectrum or image quality. A placement of superimposed information bits onto pixels of an image signal to be transmitted may be determined by testing a placement functions to determine whether the spectrum and/or image quality of the image signal with the superimposed information bits placed according to a placement function meets system criteria. Successive placement functions may be tested until an acceptable placement function is found. The information bits may be superimposed onto complete pixels or the information bits may be superimposed onto one or more least significant bits (LSBs) of each of the selected pixels. A transmitter may transmit superimposition information associated with a transmitted image to a receiver. A receiver may use the superimposition information to extract the information bits.

    Abstract: A device is described. The device includes a data interface connector, an application processor, and interface circuitry. The application processor can receive signals via an antenna. The interface circuitry can be coupled between the application processor and the data interface connector. The data interface circuitry can determine a change in a signal property of one of the signals, the change being caused by an impedance mismatch between the data interface connector and a media consumption device. The data interface circuitry can also send the application processor a signal property setting corresponding with the change. The application processor can adjust the signal property of a subsequent one of the signals, in response to the signal property setting from the interface circuitry, to obtain an adjusted signal. The application processor can also send the adjusted signal to the media consumption device.

    Abstract: Embodiments of the present disclosure provide a subtitle display method and a subtitle display device, and relate to the field of communications technologies. Category content is presented to a user in an interactive graphic manner, so that the user can select corresponding category content according to the user's preference, and subtitles corresponding to the category content are displayed. The method includes receiving a subtitle file, and parsing a category label of the subtitle file, where the category label includes category content; presenting, on a display device in an interactive graphic manner, the category content for a user to perform selection; and receiving a result of selecting one or more pieces of the category content by the user, and displaying, according to the selection result, subtitles corresponding to the selected category content, therefore classified display of subtitles is implemented.
