Encoding apparatus and decoding apparatus for a digital video disc |
摘要 |
At least one musical composition is transmitted via a digital video disc together with bonus information relating to the musical composition and an approved interactive data required when a user accesses the bonus information. An arbitrary interactive data is entered by the user accessing the bonus information. The transmitted musical composition is reproducible regardless of the entered interactive data. However, a reproduction of the bonus information is allowed only when the entered interactive data agrees with the approved interactive data.
