Bit rate control interface for the recording and/or reading of digital data

摘要

The invention relates to a control interface for the bit rate of digital data to be recorded as well as to a control interface for the bit rate of digital data emanating from a reading device. Each control interface comprises a memory circuit for storing the data to be recorded or to be read and means whereby the data to be recorded or to be read can be stored in the memory circuit in such a way as to fill the memory circuit to a predetermined level. The means for storing in the memory circuit the data to be recorded or to be read comprise a gauge for generating an information item giving the fill level of the memory. The invention applies more particularly to the case where the digital data constitute a high bit rate uninterrupted data stream such as a video data stream in the MPEG II format. <IMAGE>
