Abstract (en)
[origin: EP2711924A1] A bitstream transmission device (200) according to the present invention includes: an input unit (100) which acquires an elementary audio stream obtained by coding an audio signal; an analysis unit (101) which analyzes a sampling frequency and a coding format of the elementary audio stream (300); a preamble generation unit (102) which, when the analyzed sampling frequency and coding format do not comply with a standard, generates a preamble signal specifying a coding format that complies with the standard as information indicating a coding format of the elementary audio stream (300); and a forming unit (103) which forms an audio bitstream (301) in accordance with the standard by incorporating the generated preamble signal in the elementary audio stream (300).
