Image Conversion for License-Free Streaming Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Client terminals without the necessary license cannot reproduce images, and existing systems require server processes to convert images for specific terminal specifications, increasing server load.
Innovation Solution
An information processing apparatus and method that converts images requiring license information into a format not requiring such information, allowing streaming reproduction on client terminals, reducing server load by distributing a thumbnail image and a converted image with lower data volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the server converts images to formats not requiring license information, then client terminals without licenses can reproduce images, but the server load increases
Solution Approach 1:
The server performs image format conversion in advance during the upload process, before the client needs to reproduce the image. By converting images to license-free formats proactively, the system ensures clients can reproduce images without needing to request conversion later, thereby reducing server load during actual reproduction operations.
Solution Approach 2:
The server creates a copy of the uploaded image in a license-free format while retaining the original licensed format. This copying approach allows the server to provide both formats without requiring full conversion of all images, reducing the overall conversion burden while ensuring compatibility for clients without licenses.
2Reliability
If the server waits for complete image acquisition before enabling reproduction, then license verification can be performed, but the client terminal cannot reproduce images during acquisition
Solution Approach 1:
The server converts images to license-free formats in advance during upload, before the client completes acquisition. This preliminary conversion ensures that when the client starts reproducing the image during acquisition, the converted format is already available, eliminating the need to wait for complete acquisition and license verification before reproduction begins.
Solution Approach 2:
The converted image format acts as an intermediary that bridges the gap between acquisition and reproduction. By providing a license-free converted version during the acquisition process, the system allows reproduction to proceed concurrently with acquisition, while the original licensed format remains available for post-acquisition verification and high-quality reproduction.

AI summary
There is provided an information processing apparatus, including a storage section which stores a first image, which is an image of a format requiring license information in reproduction, to which reproduction is performed by a reproduction apparatus after being acquired, a conversion section which converts the first image into a second image of a format not requiring license information in reproduction, which is an image with content the same as content of the first image, and a distribution section which distributes the second image to the reproduction apparatus to be reproduced, during acquisition of the first image.
