Abstract
Abstract An information processing apparatus in which continuous data of a plurality of series in which the contents of the data of each series are related to each other with respect to time is pipeline processed by a data processing system. The apparatus comprises a plurality of sync generation circuits which correspond to the plurality of series and each of which generate sync signals to instruct timings for the data transfer and data process of each series, and a sync control circuit for controlling generation situations of the sync signals from the plurality of sync generation circuits in accordance with a degree of progress of the data process of each series in the data processing system so that the data of each series can be processed in the data processing system without losing the time-dependent relation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
128 words
An information processing apparatus in which a plurality of different kinds of data series in which the contents of each of the data series are related to each other with respect to a time, are pipeline processed by a data processing system, comprising: a plurality of sync generation means each for generating a sync signal indicating timings for data transfer and data process of said plurality of data series; and sync control means for controlling generation cycles of the sync signals in said plurality of sync generating means in accordance with a degree of progress of the pipeline process of said plurality of data series in said data processing system so that each of the data series is reproduced at the same timing by a predetermined reproducing means.
Claim 2
Dependent Claim
128 words
An information processing apparatus in which a plurality of different kinds of data series in which the contents of each of the data series are related to each other with respect to a time, are pipeline processed by a data processing system, comprising: a plurality of sync generation means each for generating a sync signal indicating timings for data transfer and data process of said plurality of data series; and sync control means for controlling generation cycles of the sync signals in said plurality of sync generating means in accordance with a degree of progress of the pipeline process of said plurality of data series in said data processing system so that each of the data series is reproduced at the same timing by a predetermined reproducing means.
Claim 3
Dependent Claim
21 words
An apparatus according to claim 1, wherein the plurality of different kinds of data series include image data and audio data.
Claim 4
Dependent Claim
19 words
An apparatus according to claim 1, wherein each of said data series is input through a different data source.
Claim 5
Dependent Claim
17 words
An apparatus according to claim 1, wherein said plurality of sync generating means generate different sync signals.
Claim 6
Dependent Claim
19 words
