Compressed Partial Data Retrieval for Network Output Formatting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large data volumes read from network-connected devices can cause bandwidth tightening and increase processing loads in information processing devices, especially when data is not compressed before storage.
Innovation Solution
Implementing an information processing device with a receiving unit for reading instructions, a data obtaining unit for obtaining compressed data from an external storage device via a network, and a data output unit for expanding the compressed data, allowing the device to manage data processing based on whether the data is stored in a CD-DA formatted area, thereby reducing bandwidth constraints and processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is compressed before storing in an external storage device connected via a network, then the possibility of bandwidth tightening in the network is reduced, but data expansion must be performed for all read data which increases processing load in the information processing device
Solution Approach 1:
The patent applies local quality by differentiating processing based on data location: data in the CD-DA area is stored and processed in compressed format, while data in other areas is handled in uncompressed format. This selective approach optimizes network bandwidth for large data (audio) while avoiding unnecessary expansion processing for smaller data, thus resolving the contradiction between reduced bandwidth usage and minimized processing load.
2Adaptability or versatility
If data is read from an external storage device via a network, then data can be accessed remotely, but bandwidth tightening occurs due to large data volumes
Solution Approach 1:
The patent applies preliminary action by pre-compressing data before storing it in the external storage device, particularly for the CD-DA area. This advance compression reduces the data volume that needs to be transmitted over the network when data is read, thereby maintaining data access flexibility while significantly reducing bandwidth consumption during actual data retrieval operations.

AI summary
An information processing device includes a receiving unit (54) configured to receive a reading instruction to read a part of a data file, the part containing less data than the data file; a data obtaining unit (60) configured to obtain the part designated by the reading instruction from an external storage device connected via a network; and a data output unit (66) configured to output the part designated by the reading instruction, wherein when the reading instruction is a reading instruction to read the part and the part is stored compressed in the external storage device connected via the network, the data obtaining unit (60) obtains the part, compressed, designated by the reading instruction, and the data output unit (66) outputs data obtained by expanding the compressed part.
