Abstract:
1. A signal output device comprising: an output signal generating unit generating output signals based on input data defined as inputted moving picture data or audio data; an output control unit outputting the output signals generated by said output signal generating unit to a reproducing device; a detecting unit detecting missing of the input data; and a substitute data generating unit generating, when said detecting unit detects the missing of the input data, substitute data by averaging at least any one of input data posterior to the missing portion and input data anterior to the missing portion, as data for a period of reproducing time obtained by adding a period of reproducing time related to the input data to a period of reproducing time related to the missing portion, wherein said output signal generating unit, when said detecting unit detects the missing of the input data, generates the output signals based on the substitute data, said detecting unit detects the missing of the input data by monitoring the input data posterior by a predetermined period of time from an output portion of said output control unit, and said substitute data generating unit, when said detecting unit detects the missing of the input data, executes: a first substitute data generating process of generating data for conversion and the substitute data substituting for the input data of the missing portion by averaging the data for conversion defined as the input data anterior to the missing portion in the input data but posterior to the output portion, as the data for the reproducing time obtained by adding the reproducing time related to the data for conversion to the reproducing time related to the missing portion; and a second substitute data generating process of generating the substitute data substituting for subsequent input data by adding the subsequent input data defined as the input data subsequent to just-before substitute data to the just-before substitute data defined as the substitute data generated just before and averaging these added pieces of data.
