1. A method for encoding an audio and/or video signal into an encoded signal which can be decoded by a decoding device including a decoder buffer for receiving the encoded signal and a decoder for decoding the encoded signal, the method comprising:

  • encoding successive portions of the audio and/or video signal into corresponding successive code blocks making up the encoded signal;

    determining a delay time parameter for a code block of the code blocks, which delay time parameter represents a length of time during which the code block is to be stored within the decoder buffer before decoding by the decoder in order to ensure that the decoder buffer will not experience overflow or underflow of the code blocks; and

    inserting the delay time parameter into the encoded signal.
