Data transmission method for embedded data, data transmitting and reproducing apparatuses and information recording medium therefor
First Claim
1. A data transmission method for information data containing additional information data therewith, comprising, at a transmitter side, following steps:
- a fist step for adding error correction codes for correcting error to said additional information data;
a second step for embedding said additional information data added with said error correction codes into the information data by plural times, repetitively; and
a third step for transmitting the information data embedded with the repetitive additional information data therein.

Abstract
In a data transmission method for information data containing additional information data therewith, comprising, at a transmitter side, following steps:
adding error correction codes for correcting error to said additional information data;
embedding said additional information data added with said error correction codes into the information data by plural times, repetitively; and
transmitting the information data embedded with the repetitive additional information data therein, and comprising, at a receiver side, following steps:
receiving the transmitted information data embedded with the repetitive additional information data therein;
detecting the repetitive additional information data embedded from said transmitted information data received;
determining said additional information data on a basis of a majority rule when receiving said information data; and
correcting error with using the error correction codes received and determined when said additional information data contains error(s) therein.
