IC Card Offline Multimedia Access for Mobile Phones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accessing multimedia content in geographical areas using mobile devices are limited by the inability to store content offline, lack of call reception during network coverage, and the need for bulky and expensive PDAs or mobile computers.
Innovation Solution
A method utilizing an IC Card in a mobile phone to download multimedia content from a provider, allowing offline playback and simultaneous call reception, with automated or manual detection of geographical areas and item-specific content access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multimedia content is downloaded into mobile device memory, then offline playback is enabled, but device memory capacity is insufficient
Solution Approach 1:
The patent embeds an IC card within the mobile device to create a nested storage structure. The IC card contains additional memory capacity that supplements the device's internal memory, allowing multimedia content to be stored offline without requiring the device itself to have large storage capacity.
Solution Approach 2:
The IC card acts as an intermediary storage medium between the network and the mobile device memory. It receives content downloads and provides offline playback capability, mediating the storage capacity limitation of the device while enabling reliable offline access to multimedia content.
2Productivity
If mobile phone connects to multimedia content provider during playback, then content can be accessed, but incoming phone calls are blocked
Solution Approach 1:
The system downloads and stores multimedia content in advance on the IC card before the user needs to access it. This preliminary action allows the content to be played back offline without maintaining an active network connection during playback, thereby preventing calls from being blocked while enabling content access.
3Reliability
If PDA or mobile computer is used to store multimedia content, then offline playback is enabled, but device size and weight increase
Solution Approach 1:
The IC card is a compact, credit-card-sized storage medium that nests within the mobile device. This nested structure provides the offline playback capability of larger devices like PDAs while maintaining the portability and light weight of a standard mobile phone, avoiding the need to carry separate bulky devices.
4Productivity
If audio/video guide is rented and carried, then multimedia content is accessible, but user mobility is reduced due to additional weight
Solution Approach 1:
The patent merges the multimedia content storage and playback functionality directly into the mobile device via the IC card. This combination eliminates the need to carry separate audio/video guide equipment, as the mobile device itself becomes sufficient for both communication and multimedia content access, reducing total carried weight while maintaining content access capability.

AI summary
A method is for accessing multimedia contents associated with a geographical area including a plurality of items, the multimedia content being stored on a multimedia content provider having information of one or more of the items. The method provides an IC Card application for enabling a mobile device to detect a geographical area of interest, connect to the multimedia content provider and select at least one multimedia content of the detected geographical area of interest, download the selected multimedia content into a memory of the IC Card, provide an identification code of an item located into the detected geographical area of interest, and access a portion of the multimedia content which stores information of the identified item.
