Content Acquisition Apparatus Distinguishing Stored and Missing Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional music transfer systems are inefficient in acquiring musical data from a music storage apparatus to a music reproduction apparatus, as users must manually search through large amounts of data to identify and transfer missing content, making the process cumbersome and time-consuming.
Innovation Solution
A content acquisition apparatus and method that distinguishes between stored and non-stored content by using unique identification outputs, allowing users to easily select and acquire missing content from a content providing apparatus, enhancing efficiency in data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users manually search through large amounts of existing musical data to identify and transfer missing content, then complete content transfer can be achieved, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically generating a transfer list that identifies missing musical data before the user initiates the transfer process. The control section compares the reproduction apparatus's stored data with the storage apparatus's data, pre-calculating which files need transfer, thereby eliminating the need for users to manually search through large datasets.
Solution Approach 2:
A transfer list serves as an intermediary between the user and the large dataset. Instead of directly searching through numerous musical files, the user interacts with a simplified transfer list generated by the control section, which mediates the complex data comparison process and presents only the necessary transfer information.
2Loss of information
If all content identifications are displayed uniformly, then complete information is provided, but users cannot easily distinguish between stored and non-stored content
Solution Approach 1:
The display section applies local quality differentiation by showing distinct visual representations for different content statuses. Transfer list items indicating missing content are displayed with one visual characteristic (e.g., specific icon or formatting), while already-stored content items are displayed with different visual characteristics, enabling users to quickly distinguish between stored and non-stored content without losing information about either state.

AI summary
The present invention provides a music purchasing/transfer system allowing contents to be acquired in a remarkably efficient manner. In the system, a content acquisition apparatus, and method and program thereof are provided. The apparatus includes a content storage section used for storing contents; an output section for outputting the identification of every content that can be presented by a content providing apparatus for presenting contents; and a content acquisition section for acquiring a content, which is identified by a content identification selected by carrying out an operation to select one of identifications output by the output section, from the content providing apparatus, wherein the output section outputs identifications of contents not stored yet in the content storage section as identifications different from other identifications output as identifications of other contents already stored in the content storage section.
