Abstract (en)

[origin: US2004162911A1] In a method for generating a scalable data stream, when a block of output data of a first encoder is present, this block of output data is written into the scalable data stream. If output data of a second encoder is present for a preceding period of time, this output data for the preceding section is written in transmission direction behind the block of output data of the first encoder into the data stream. When the output data of the scalable encoder for the current section is present, the output data of the second encoder is written into the bit stream subsequent to the output data of the first encoder. A determining data block is generated and written into the bit stream delayed by a period of time which corresponds to the size of the bit savings bank of the second encoder. Finally, buffer information is written into the bit stream, which indicates, where the beginning of the output data of the second encoder for the current section regarding the determining data block is, wherein the buffer information corresponds to the bit savings bank level. Thus, it is possible to simply signalize a bit savings bank in a scalable data stream. The maximum size of the bit savings bank may further be adjusted depending on the intended decoder delay and be communicated to a decoder by positioning the determining data block in the scalable data stream without an effort of additional bits in order to reduce the initial delay of the decoder.
