Embodiments of the present disclosure relate to the field of multimedia technology, and discloses a method and electronic device for optimizing playback of a stereoscopic film source and an apparatus. Some embodiments of the present disclosure include the following steps: acquiring a stereoscopic adjustment parameter related to a timeline of a stereoscopic film source, wherein the stereoscopic adjustment parameter includes T offset adjustments and time periods corresponding to the T offset adjustments, wherein T is a natural number; and when the stereoscopic film source is played in a stereoscopic mode, adjusting an offset of a frame that is in the time period, wherein the adjusted offset is the offset adjustment corresponding to the time period.

To determine whether or not a correct continuous reproduction disk has been attached, and perform control in accordance with a determination result in a data reproduction process including a first information recording medium and a second information recording medium. A first root certificate transform value is calculated by applying a first transform function to data constituting a first root certificate recorded in the first information recording medium and a second root certificate transform value is calculated by applying a second transform function to data constituting a second root certificate recorded in the second information recording medium. Transform values based on first and second root certificates are compared. A process under execution is continued when the first and second root certificate transform values match. However, the process under execution is stooped or a warning is output when the first and second root certificate transform values do not match.

A multivariant video segmentation system and method including accepting video segments that make up a video, accepting video segment variants for the video segments, and selecting a particular video segment variant to provide as a video segment at a particular sequential time order. The video segments are provided to a user at each relative sequential time order via a video player on a first webpage, user inputs associated with the video player and at least one webpage are accepted, and engagements and conversions from the user inputs are determined and stored. The engagements include at least a viewing time of the user viewing the video, and conversions include completion of a predefined task by the user that differs from the user viewing the video. The video segment path with the highest engagement or conversion value associated with information related to the user viewing the video is provided to the user.

Assistance information related to a tier framework may describe signaling for extractable and decodable sub-sequences based on pictures interdependencies. This may allow a video application to efficiently select pictures when performing a given trick mode.

The present invention relates to an input/output system for an ultra high definition image, and more specifically, to an input/output system for an ultra high definition image that may receive an ultra high definition image signal from an external device, process the signal in real time, and output the processed ultra high definition image signal. For this purpose, a system configured to convert data having various resolutions into UHD data of the present invention includes a content input/output device configured to provide data received from a data providing device to an editing device and provide the data received from the editing device to a content reproducing device, and an editing device configured to convert the data received from the content input/output device into UHD data and provide the result to the content input/output device.

For playing an interactive audiovisual movie, a movie episode data object which comprises a plurality of audio/video segments, separate audio tracks, and playback instructions is stored (51) in a data store of a computerized playback device. The playback device retrieves (52) the play-back instructions and, in accordance with the playback instructions, retrieves (S31) and plays (532) audio/video segments, generates (535) interface elements for receiving from a user decision commands while playing the audio/video segments, and retrieves (S31) and plays (S32) further audio/video segments depending on the user decision commands. The play-back device further retrieves (S33) one of the separate audio tracks and plays (S34) the separate audio track uninterruptedly while playing an end of which is played subsequently to the first audio/video segment. Thus, an audio track is played uninterruptedly across the boundary of two consecutive audio/video segments.

The present invention pertains to an apparatus and method for adding a graphic element, such as a subtitle to selected locations of the frames in a 3D movie. The authoring tool receives a depth map indicating the position of various objects in the frames of 3D content along a Z-axis. The authoring device then designates a position for at least one additional graphic element in at least some of the frames, these positions being determined in relation either to the positions of the objects or the position of the screen along said Z-axis. An encoder uses parameters from the authoring tool to reauthor the 3D movie by adding the graphic content to the positions designated by the parameters.

A playback device includes: an attribute reader that reads out first attribute information, indicating whether a dynamic range of luminance of the video stream is a first dynamic range or a second dynamic range, from a management information file recorded in the recording medium in a manner correlated with the video stream; a decoder that generates decoded video information by reading the video stream out from the recording medium and decoding the video stream; and an outputter that, in a case where the first attribute information that has been read out indicates the second dynamic range, outputs the decoded video information, along with maximum luminance information indicating a maximum luminance of the video stream in accordance with the second dynamic range.
