Abstract
A recording medium which records thereon moving pictures encoded by a first encoding method, first pictures corresponding to the moving pictures and which have pixels smaller than the moving pictures, still pictures encoded by a second encoding method, and second pictures corresponding to the still pictures and which have pixels smaller than the still pictures.
Claims15
A machine-readable recording medium comprising:
- a first still picture recorded thereon encoded by a first encoding methods, wherein the first still picture having descriptive information associated therewith to allow a machine to recognize and decode the first still picture for display;
- a second still picture recorded thereon encoded by a second encoding method, wherein the second still picture having descriptive information associated therewith to allow the machine to recognize and decode the second still picture for display, wherein the second encoding method is different from the first encoding method;
- and
- a picture recorded thereon corresponding to said first and second still pictures, which has a smaller number of pixels than said first and second still pictures, wherein the picture having descriptive information associated therewith to allow the machine to recognize and decode the picture for display,
- wherein said first still picture, said second still picture and said picture are related pictures derived from common signal data.
