Patent ID: 7451160

Claim:
A multimedia-data integration apparatus comprising: a memory; and a computer processor reading the memory and executing a calculating unit that calculates a processing sharing ratio, by using a conjugate gradient method, with which the multimedia-data integration apparatus together with a first multimedia-data accumulation apparatus and a second multimedia-data accumulation apparatus both connected to the multimedia-data integration apparatus via a network share a conversion processing for converting a data format of first multimedia data including second multimedia data accumulated in the first multimedia-data accumulation apparatus and third multimedia data accumulated in the second multimedia-data accumulation apparatus into a different data format; a sending unit that sends the processing sharing ratio to each of the first and second multimedia-data accumulation apparatuses; a receiving unit that receives from the first multimedia-data accumulation apparatus, first voice data and first image data both separated from the second multimedia data, the first image data including first data that has not been subjected to conversion processing and second data that has been subjected to conversion processing by the first multimedia-data accumulation apparatus based on the processing sharing ratio, the first voice data having been subjected to conversion processing by the first multimedia-data accumulation apparatus, and from the second multimedia-data accumulation apparatus, second voice data and second image data both separated from the third multimedia data, the second image data including third data that has not been subjected to conversion processing and fourth data that has been subjected to conversion processing by the second multimedia-data accumulation apparatus based on the processing sharing ratio, the second voice data having been subjected to conversion processing by the second multimedia-data accumulation apparatus; a conversion processing unit that applies the conversion processing for a data format of the first and third data received by the receiving unit; and an integrating unit that integrates the converted first data, the received second data, the converted third data, and the received fourth data, and the received first and second voice data to create integrated multimedia data.
