Document Type and Number:

Japanese Patent JP3777279

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To reproduce data in a data reception terminal with low delay and to accumulate data with high quality.
SOLUTION: When a received data quality monitoring part 33 judges that the data quality of a period, which is received from a data transmission terminal 2, dose not satisfy prescribed accumulation quality, an alternate data transmission request part 37 requests alternate data satisfying accumulation quality on data of the period whose accumulation quality is satisfied above quality from the data transmission terminal 2 so as to obtain data.
