Abstract:
1. A data output method for accumulating received data in an accumulating unit to which an initial accumulation amount as a basis for starting to output the accumulated data and an upper accumulation limit amount as a basis for discarding the accumulated data are set, and performing output based on the data accumulated in said accumulating unit, comprising the steps of: checking an accumulated state of the data accumulated in said accumulating unit, at a preset check interval; judging whether or not discarding of data based on said upper accumulation limit amount has occurred, when a judgment is made in said step of checking that an accumulated amount of the data accumulated in said accumulating unit is not less than a predetermined reference amount; decreasing set values of said initial accumulation amount and said upper accumulation limit amount, when a judgment is made that the discarding of the data has not occurred in the step of judging; decreasing the set value of said initial accumulation amount while said upper accumulation limit amount is left unchanged, when a judgment is made that the discarding of the data has occurred in the step of judging; and extending a set period of said check interval, when the judgment is made that the discarding of the data has occurred in the step of judging, wherein the predetermined reference amount is a capacity amount of a buffer, which is used for the outputting of the data, the buffer being for temporarily storing the output data when the received data is outputted.
