ABSTRACT:
An apparatus and a method of encoding a digital signal with which a transmission buffer (an encoder buffer) does not overflow even if recording of a signal on a recording medium is temporarily inhibited attributable to, for example, an external shock or even if transmission of a signal by broadcast or communication is temporarily inhibited because of unsatisfactory state of communication. In a case where recording on an optical disk is temporarily inhibited and an output of data from an encoder is interrupted attributable to, for example, an external shock during an operation for recording a bit stream obtained by encoding a video signal on the optical disk, an encoding bit rate is lowered. Thus, a fact that the encoder buffer overflows can be prevented.
