摘要： Systems and methods for selectively enabling enhanced high dynamic range (HDR) metadata for enhanced HDR playback of media content stored on a media disc are provided. Media discs may be authored with a base layer media content in accordance with a non-enhanced HDR media profile. Media discs may also include enhanced HDR metadata. In order to enable the use of the enhanced HDR metadata, a media player in which the media disc is inserted for playback may first seek authorization from a third-party resource, such as an authorization server. Only after obtaining authorization is the media player allowed to playback the media content stored on the media disc in conjunction with the enhanced HDR metadata. If authorization is not obtained, the media player may only play the base layer media content.

摘要： A system and method for selecting portions of video data from preview video data is provided. The system may extract image features from the preview video data and discard video frames associated with poor image quality based on the image features. The system may determine similarity scores between individual video frames and corresponding transition costs and may identify transition points in the preview video data based on the similarity scores and/or transition costs. The system may select portions of the video data for further processing based on the transition points and the image features. By selecting portions of the video data, the system may reduce a bandwidth consumption, processing burden and/or latency associated with uploading the video data or performing further processing.

摘要： A system and method that repeat video images in a deinterlacing system. The method comprises detecting a signal requesting an input video image be repeated and determining the desired number of repetitions. The input video image may then be processed to generate an output video image and the output video image may be repeated the desired number of repetitions. The input video images following the repeated image may be held until the repeating is completed, and may then be processed and displayed. Repeating the video image may be utilized to achieve different playback modes such as, for example, slow motion, pause, and video rate conversion.

摘要： A recordable and/or rewriteable recording medium for storing still picture data, and recording and/or reproducing method and apparatus therefor. The recording medium stores still picture group information for grouping a plurality of still pictures in order to manage the still picture at a group level, and stores audio group information for grouping additional audio data added to the still picture data after the still picture data are recorded. Therefore, large-capacity still picture data and additional audio data added thereto can be recorded using a minimum amount of management information. Further, during reproduction, data can be displayed and edited in units of the respective still pictures. Also, it is possible to cope with after-recording of the audio data.

摘要： There are provided steps of extracting parts of two image data as areas for analysis (S702, S704) and an image difference detection step (S707) of detecting an image difference between the two images, based on a difference in image characteristic values of the regions for analysis; the regions for analysis in the two image data have identical size. If no image difference is detected, the region extraction steps may expand the regions for analysis (S707) by adding part or all of the image data that was not previously included in the regions for analysis (S704). Scene changes can be done rapidly in images and video.
