Abstract: This disclosure describes methods and apparatus for decoding data. In one aspect, the method comprises decoding encoded video data to obtain decoded video frame data, the encoded video data comprising encoded video frame data encoded at a first frame rate and embedded data. The method further comprises determining a camera parameter from the embedded data and up-converting the decoded video frame data to a second frame rate based on the camera parameter. The determined camera parameter may be, for example, a parameter associated with one or more of a zoom factor, an auto focus status, lens position information, frame luma information, an auto exposure (AE) convergence status, an automatic white balance (AWB) convergence status, global motion information, and frame blurriness information, and the like. An encoding device may embed the camera parameter(s) in an encoded video bit stream for a decoder to utilize during frame rate up-conversion.

Abstract translation: 本公开描述了用于解码数据的方法和装置。 一方面，该方法包括解码经编码的视频数据以获得解码的视频帧数据，编码视频数据包括以第一帧速率编码的编码视频帧数据和嵌入数据。 该方法还包括从嵌入数据确定相机参数，并且基于相机参数将解码的视频帧数据上变频到第二帧速率。 确定的相机参数可以是例如与缩放因子，自动对焦状态，透镜位置信息，帧亮度信息，自动曝光（AE）收敛状态，自动白平衡（AWB）中的一个或多个相关联的参数 ）收敛状态，全局运动信息和帧模糊信息等。 编码设备可以将相机参数嵌入编码视频比特流中，以供解码器在帧速率上变频期间使用。
