Information transmission method and encoding/decoding apparatus and encoding-multiplexing/decoding-demultiplexing apparatus in information transmission system to which information transmission method is applied

An information receiving apparatus comprising:

• means for receiving a data stream including header information and encoded information;
• means for reconstructing the header information by using reconstruction information which at least includes a part of the header information, when the receiving means fails to detect the header information;
• and
• means for decoding the encoded information into decoded information,
• wherein the encoded information contains a picture code stream obtained by compress-encoding a picture signal, and the reconstruction information indicates a display timing of each picture frame of the picture code stream.
