Information output apparatus, information output method and information output program
First Claim
1. An information output apparatus comprising;
- a generating device for generating output information;
an output device for generating and outputting information packets containing the generated output information and the control information used for processing the generated output information outside; and
an output control device for controlling the output device in such a manner as to output the information packets containing the fixed value information having a fixed value preset in place of the output information when the output information is not generated by the generating device.

Abstract
To provide an information output apparatus in which even when the output of an isochronous packet containing the audio information or the like is suspended and restarted, the process for the audio information or the like can be quickly resumed and the occurrence of the headless state of the audio information after resumption of the process can be prevented.
In an information output apparatus for outputting an isochronous packet containing the audio information and the sync information, it is determined whether the audio information is output or not (step S1), and when the audio information is not output, a soundless packet containing the fixed value information having a preset fixed value replacing the audio information and the control information is output (steps S9, S11)
