摘要： Simulating film grain in an encoded image occurs by extracting the film grain and then characterizing the film grain for encoding in a video stream to enable the film grain restoration upon decoding. Typically, the film grain is characterized based either on the type of film, or by using a particular model. In practice, the film grain particulars are transmitted as parallel information to the video coded stream, typically as a film grain Supplemental Enhancement Information (SEI) message when using the ITU T H.264 video coding standard.
摘要翻译：在编码图像中模拟胶片颗粒通过提取胶片颗粒，然后表征胶片颗粒以在视频流中进行编码，以使得胶片在解码时恢复。通常，胶片颗粒的特征基于胶片的类型，或通过使用特定的模型。实际上，当使用ITU T H.264视频编码标准时，胶片颗粒细节作为并行信息被传送到视频编码流，通常作为胶片颗粒补充增强信息（SEI）消息。

摘要： According to a general aspect, a decoded picture is removed from memory based on dependency information that describes one or more inter-view dependency relationships for the picture. Implementations may also include accessing a picture from a first view and the dependency information. The dependency information may describe one or more inter-view dependency relationships for the picture from the first view. The picture from the first view may be decoded to produce the decoded picture. The decoded picture may be stored in memory. One application area involves removing pictures from a decoded picture buffer when such pictures are no longer needed as a reference picture.

摘要： A decoder (10) conceals errors in a coded image comprised of a stream of macroblocks by examining each macroblock for pixel errors. If such errors exist, then each of at least two macroblocks pictures from each of two different pictures are weighted to yield a weighted prediction (WP) for estimating missing/corrupt values to conceal the macroblock found to have pixel errors.
摘要翻译：解码器（10）通过检查每个宏块的像素误差来隐藏由宏块流组成的编码图像中的错误。如果存在这样的错误，则对两个不同图像中的每一个的至少两个宏块图像中的每一个进行加权，以产生用于估计丢失/损坏值的加权预测（WP），以隐藏发现具有像素误差的宏块。

摘要： Temporal concealment of missing/lost macro blocks relies on the direction mode derivation process typically standardized in video decoders. Upon detecting an error in the form of a picture (FIG. 1) a co-located macro block is found previously transmitted picture. The motion vector for that co-local macro block is determined (FIG. 2). The identified macro block is predicted by motion compensating data from a second previously transmitted picture in accordance with the motion vector determined for the co-located macro block (FIG. 3).
