Patent ID: 7895634

Claim:
A data processing apparatus comprising: a combining device for combining main data including at least one of audio data and image data exhibiting a reference frame rate FR r , with associated information, said associated information including set frame rate data (FR s ) representing a reproduction speed for said main data, FR s =nFR r (n is an integer or a fraction), said associated information selectively including limitation information for limiting the reproduction speed of said main data to a predetermined range of reproduction speeds having a maximum speed less than a fast reproduction speed selectable by a user, and said associated information further including recommended data representing a recommended reproduction speed at which a reproduction device is set to reproduce a predetermined content of said main data, said recommended reproduction speed being within said predetermined range, said user-selectable reproduction speed being a fast speed produced by skipping selected frames of said main data as a function of FR s , and said user-selectable reproduction speed being a slow speed produced by repeating selected frames of said main data as a function of FR s said maximum speed of said predetermined range being greater than said reference frame rate FR r and being set for said predetermined content of said main data and not capable of being overridden by the user-selectable fast reproduction speed, thereby permitting said user to reproduce the predetermined content at a fast speed within said predetermined range and inhibiting said user from exceeding said maximum speed when reproducing the predetermined content of said main data; and a transmitting device for transmitting said main data combined with at least said set frame rate data FR s of said associated information.
