Abstract
First digital data ( ) obtained by encoding a low-resolution digital video signal at a low-resolution compression encoder ( ) and second digital data ( ) obtained by encoding a high-resolution digital video signal at a high-resolution compression encoder ( ) are multiplexed and transmitted with information relating to programs wherein identification information for identifying both digital data ( ) is described, and at a receiving ( ) side, the first and second digital data are identified on the basis of the identification information, and are reproduced by corresponding decoders ( ). Therefore, when image of different resolutions is transmitted by multiplexing, it is possible to reproduce data correctly at the receiving side, thereby increasing freedom in program composition.
