Abstract:
1. A method for generating a data stream, comprising: entering first text into the data stream; entering an escape-start-sequence into the data stream, the escape-start-sequence defining a first set of data units that are to be skipped by a base decoder but to be interpreted by an extension decoder, entering the first set of data units into the data stream, entering an escape-continuation-sequence into the data stream, the escape-continuation-sequence defining a second set of data units that are to be skipped by the base decoder but to be interpreted by the extension decoder together with the first set of data units; entering the second set of data units into the data stream; and entering second text following the second set of data units; wherein the escape-start-sequence includes an escape-start code signaling a beginning of the escape-start-sequence and a first length code identifying a first number of data units of the first set of data units, the escape-continuation-sequence includes a continuation code signaling a beginning of the escape-continuation-sequence and a second length code identifying a second number of data units of the second number of data units, the escape-start code is different from the continuation code, or, alternatively, the escape-start code and the continuation code are identical and the first length code includes a maximum length signal, when the first length code includes the maximum length signal, a code following the first length code including the maximum length signal in the data stream is the continuation code of the escape-continuation-sequence; the first set of data units and the second set of data units are mutually exclusive; and at least one of entering the first text, entering the escape-start-sequence, entering the first set of data units, entering the escape-continuation-sequence, entering the second set of data units, and entering the second text is performed by an inserter, the inserter comprising a hardware implementation.
