Method and device for the generation or decoding of a scalable data stream with provision for a bit-store, encoder and scalable encoder

A method for generating a scalable data stream (scalable data stream), in the case of outputting data blocks of the first encoder 11 is present, the output block of data is written into the scalable data stream. The presence of the second encoder for the output data (0) is the preceding period, the output data for the preceding section is written to the transport direction in front of the output data block 11 of the first encoder for the data stream. If there is output data (1) of the scalable encoder for the current section, the output data of the second encoder is written in the bit stream following the output data of the first encoder. Determining data block (200) is generated and written into the corresponding time period 250 is delayed by the size of the bit savings bank bit stream (bit savings bank) of the second encoder. Finally, the output data of the second encoder for the current section according to the determining data block are written into the buffer information (260) a bitstream indicating that where starting from, where the buffer information 26 is the bit It corresponds to a savings bank level. Therefore, it is possible to simplify a signaling bit savings bank in the scalable data stream. The maximum size of the bit savings bank, according to an intended decoder delay, and further can be adjusted, the decoder by position in the scalable data stream, the determination data block without trying to add a bit to reduce the initial delay of the decoders It can be communicated to.A scalable data stream (scalable data stream), the bit savings bank (bit savings bank), a scalable encoder, a delay, an initial delay, signaling, determining a data block
