Abstract: A process for decoding and for displaying in rewind mode pictures of a stream of picture data compressed according to the MPEG standard using a specified number N of frame memories each adapted for storing a decoded picture, where N is an integer greater than or equal to 4, applies rules for selecting a frame memory when a frame memory is to be overwritten so as to allow the storage of a new picture to be decoded.
Abstract translation: 一种用于解码和用于在倒带模式中显示根据MPEG标准压缩的图像数据流的图像的处理，其使用指定数量的N个适用于存储解码图像的帧存储器，其中N是大于或等于4的整数 当帧存储器被重写时，应用用于选择帧存储器的规则，以允许新图像的存储被解码。

IPC: H04N7/00
CPC classification number: H04N21/4392 , H04N21/4147 , H04N21/42661 , H04N21/4305 , H04N21/4325 , H04N21/44004
Abstract: A method and device are provided for decoding one or more audio data streams and one or more video data streams obtained from one or more sources. According to the method, portions of the audio data stream and portions of the video data stream are loaded into a set of buffer memories, and audio data and video data are supplied from the buffer memories at the input of at least one audio decoder and of at least one video decoder, respectively. The video data and the audio data are decoded with the aid of the audio decoder and of the video decoder, respectively. The loading is carried out by a management module according to the Pull mode. Alternately or additionally, the supplying is carried out by the management module according to the Push mode. The management module is regulated by the video decoder.
Abstract translation: 提供了一种方法和装置，用于对一个或多个音频数据流和从一个或多个源获得的一个或多个视频数据流进行解码。 根据该方法，音频数据流的一部分和视频数据流的一部分被加载到一组缓冲存储器中，并且在至少一个音频解码器的输入端从缓冲存储器提供音频数据和视频数据，并且 至少一个视频解码器。 借助于音频解码器和视频解码器，分别对视频数据和音频数据进行解码。 根据拉模式，管理模块进行加载。 或者或另外，由管理模块根据推送模式进行供应。 管理模块由视频解码器调节。

CPC classification number: H04N21/4307 , H04N21/4341
Abstract: A method and device are provided for synchronizing the presentation of audio frames and/or of video frames comprises the detection of presentation time stamps in a stream of frames. The presentation instant indicated by a time stamp is compared with a time delivered by a local reference clock. Depending on a variance and on an average of values of deviation between presentation instants and corresponding times indicated by the clock, the clock can be initialized according to the presentation instant indicated by a time stamp or the presentation of the frames can be adjusted.
Abstract translation: 提供了一种用于使音频帧和/或视频帧的呈现同步的方法和装置包括检测帧流中的呈现时间戳。 由时间戳表示的演示时刻与由本地参考时钟传递的时间进行比较。 根据方差和表示时刻之间的偏差值与时钟指示的相应时间的平均值，可以根据时间戳表示的显示时刻初始化时钟，或者可以调整帧的呈现。
