Abstract
In reproducing a recording medium having a main data area for recording main data, an auxiliary data area for recording auxiliary data such as image data and text data corresponding to the main data, a first control area for controlling the main data area, and a second control area for controlling the auxiliary data, the auxiliary data is reproduced in a predetermined timed relation with the main data based on synchronization information recorded in the second control area.
Claims17
A reproducing apparatus for reproducing a recording medium having main data area for recording a main program composed of main data, an auxiliary data area for recording, independently of said main program, an auxiliary program composed of auxiliary data corresponding to said main program composed of said main data in said main data area, a first control area for controlling at least a recording position of said main program composed of said main data in said main data area, and a second control area for controlling at least a recording position of said auxiliary program composed of said auxiliary data in said auxiliary data area and timing information for reproducing said auxiliary program in synchronization with said main program composed of said main data in said main data area, said reproducing apparatus comprising:
- reproducing means for reproducing said first control area, said second control area, said auxiliary data area, and said main data area sequentially;
- a memory means for storing said auxiliary program composed of said auxiliary data reproduced by said reproducing means from said auxiliary data area;
- a memory control means for reading from said memory means said auxiliary program composed of said auxiliary data corresponding to said main program in synchronization with said main program reproduced from said main data area by said reproducing means based on said timing information reproduced from said second control area by said reproducing means;
- and
- a display means for displaying said auxiliary program in synchronization with said main program, said auxiliary program being read from said memory means.
A recording apparatus for recording auxiliary data in a manner related to main data onto a recording medium having main data area for recording a main program composed of said main data, an auxiliary data area for recording, independently of said main program, an auxiliary program composed of said auxiliary data corresponding to said main program composed of said main data in said main data area, a first control area for controlling at least a recording position of said main program composed of said main data in said main data area, and a second control area for controlling at least a recording position of said auxiliary program composed of said auxiliary data in said auxiliary data area and timing information for reproducing said auxiliary program in synchronization with said main program composed of said main data in said main data area, said recording apparatus comprising:
- a recording means for independently recording said auxiliary program composed of said auxiliary data corresponding to said main program onto said auxiliary data area;
- an operating means for relating said auxiliary program recorded by said recording means to said main program recorded in said main data area;
- and
- an updating means for updating, based on said recording position of said auxiliary program recorded in said auxiliary data area by said recording means and an operation performed through said operating means, said auxiliary program composed of said auxiliary data in said auxiliary data area recorded in said second control area and timing information for use in synchronous reproduction of said auxiliary program and said main program.
A recording medium having a main data area for recording at least one main program composed of main data, an auxiliary data area for recording, independently of said main program, an auxiliary program composed of auxiliary data corresponding to said main program composed of main data, a first control area for controlling at least a recording position of said main program composed of main data in said main data area, and a second control area for controlling at least a recording position of said auxiliary program composed of auxiliary data in said auxiliary data area and timing information for reproducing said auxiliary program in synchronization with said main program, said timing information being in a form configured to be edited by a user in order to adjust the reproducing of said auxiliary program in synchronization with said main program.
