    摘要: A method of estimating a flicker on a camcorded video firstly obtains a camcorded video with unknown camcording and display settings. The camcorded video includes a flicker and a watermark. Next, a spectrum of the camcorded video is obtained by using a temporal discrete Fourier transform. Then, a temporal frequency of the flicker is estimated by looking for a local maximum value in the spectrum of the camcorded video.

    摘要: Techniques for encapsulating video streams containing multiple coded views in a media file are described herein. In one example, a method includes parsing a track of video data, wherein the track includes one or more views. The method further includes parsing information to determine whether the track includes only texture views, only depth views, or both texture and depth views. Another example method includes composing a track of video data, wherein the track includes one or more views and composing information that indicates whether the track includes only texture views, only depth views, or both texture and depth views.

    摘要: The present technique relates to a data generation apparatus, a data generating method, a data reproduction apparatus, and a data reproducing method capable of enabling a user to enjoy an HDR image.
    HDR information designated by HDR designating information is acquired from a file storing a track of a stream including the HDR information which is configured with feature information representing features of luminance of an HDR (high dynamic range) image having a dynamic range higher than that of an STD (standard) image and conversion information representing a conversion rule of converting the one of the STD image and the HDR image into the other and a target track including the HDR designating information designating the HDR information which is to be applied to the target track of interest in the HDR information of the track. The present technique can be applied, for example, to the case of applying HDR information to a subtitle having an SMPTE-TT format using XML.
