摘要： The coder makes it possible to convert a succession of video and/or audio blocks, consisting of binary combinations of N bits, into a succession of binary data blocks consisting of combinations of N bits, each binary data block corresponding to one video and/or audio block. The coder codes each end binary combination 0 or 2N−1 of each video and/or audio block in the form of a coded binary combination consisting of a nature information item In and a position information item Ip. The nature information item In gives the nature, 0 or 2N−1, of the end binary combination, and the position information item Ip gives the position which the end combination occupies in the video block. Conversely, the decoder makes it possible to reconstruct a succession of video and/or audio blocks, consisting of binary combinations of N bits, from a succession of binary data blocks such as the ones mentioned above, that is to say ones for which the end combinations 0 or 2N−1 of each video and/or audio block are coded in the form of a nature information item In and a position information item Ip.
摘要翻译：编码器使得可以将由N位的二进制组合组成的一系列视频和/或音频块转换成由N位的组合组成的一系列二进制数据块，每个二进制数据块对应于一个视频和/或音频块。编码器以由自然信息项In和位置信息项Ip组成的编码二进制组合的形式对每个视频和/或音频块的每一端二进制组合0或2N-1进行编码。自然信息项目In给出结束二进制组合的性质，即0或2N-1，并且位置信息项目Ip给出了视频块中结束组合占据的位置。相反，解码器使得可以从诸如上述的一系列二进制数据块重建由N位的二进制组合组成的一系列视频和/或音频块，也就是说，结束每个视频和/或音频块的组合0或2N-1以自然信息项In和位置信息项Ip的形式进行编码。

摘要： A control interface for the bit rate of digital data to be recorded as well as a control interface for the bit rate of digital data emanating from a reading device, particularly when the digital data constitutes a high bit rate uninterrupted data stream such as a video data stream in the MPEG II format. Each control interface comprises a memory circuit for storing the data to be recorded or to be read and a device for storing the data to be recorded or read in the memory circuit so as to fill the memory circuit to a predetermined level. The storing device includes a gauge for generating an information item giving the fill level of the memory.
摘要翻译：用于要记录的数字数据的比特率的控制接口以及用于从读取装置发出的数字数据的比特率的控制接口，特别是当数字数据构成诸如视频数据的高比特率不间断数据流时以MPEG II格式流。每个控制接口包括用于存储待记录或待读取的数据的存储器电路和用于存储要在存储器电路中记录或读取的数据以将存储器电路填充到预定水平的装置。存储装置包括用于生成给出存储器的填充级别的信息项的计量器。
