DIGITAL INTERFACE DERVICE

摘要

A signal transmission apparatus is provided for transmitting a plurality of pieces of encoded audio information encoded by the same encoding method via a digital interface to a signal reception apparatus, in which each of the plurality of pieces of encoded audio information has a sampling frequency of F or 1/2 x F. The apparatus comprises a data generating section for, based on one-frame data obtained by dividing the encoded audio information into frame s, generating at least one block, and a data output section for outputting the at least one block generated by the data generating section to the digital interface. Each of the at least one block includes a body portion, and a header portion storing management information for managing data stored in th e body portion.
