An information processing apparatus for encoding a baseband signal, the information processing apparatus includes: a data splitting block; an encoder; a control block; and a splicing block. The data splitting block is configured to acquire the baseband signal before splitting it into predetermined encoding sections. The encoder is configured to generate encoded streams by parallelly encoding a continuous plurality of the encoding sections acquired by the data splitting block from the baseband signal. The control block is configured to control the encoder to perform the parallel encoding in a manner subject to predetermined constraints. The splicing block is configured to splice the encoded streams generated by the encoder.
