Host Device Image Identification via Memory Card
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Host devices, such as set-top boxes, are limited in portability as they are hard-coded with content provider images, making them incompatible with different content providers, which restricts their ability to operate with various service providers.
Innovation Solution
An identifier routine is executed by the host device to retrieve a stored identifier from a memory card, allowing it to obtain and output images that identify the content provider, enabling compatibility with multiple providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If images are hard-coded into the host device as part of the middleware, then the host device can display content provider images reliably, but the host device loses portability and cannot operate with different content providers
Solution Approach 1:
The patent segments the image identification functionality from the host device's middleware by using a separate memory card to store provider-specific images. This allows the host device to maintain its core functionality while storing provider images externally, enabling both reliability in image display and portability across different content providers.
Solution Approach 2:
The memory card acts as an intermediary between the host device and content provider images. Instead of hard-coding images directly into the host device middleware, the memory card serves as a portable storage medium that holds provider images, allowing the host device to access these images without permanent integration, thus achieving both reliability and adaptability.
2Adaptability or versatility
If the host device is configured to work with multiple content providers, then the host device gains portability, but the host device cannot display images specific to each content provider
Solution Approach 1:
The memory card is pre-configured with content provider-specific images before being inserted into the host device. This preliminary action allows the host device to immediately display the correct provider images upon insertion without requiring reconfiguration or additional setup, maintaining both portability and provider identification capability.
Solution Approach 2:
Instead of hard-coding unique images into the host device for each content provider, the patent uses a copying approach where provider images are stored on removable memory cards. This allows the same host device to copy and display different provider images from different memory cards, achieving both portability and specific provider identification without duplicating hardware or middleware.
3Adaptability or versatility
If separate memory cards are used to provide access and security functionality for each content provider, then the host device achieves portability, but the complexity of the system increases
Solution Approach 1:
The patent merges the security functionality and image storage functionality into a single memory card component. Instead of having separate security modules and image storage systems, the memory card integrates both access/security functionality and provider image storage, reducing overall system complexity while maintaining portability across different content providers.
Data Source
AI summary
An identifier routine is described which, when executed by a host device, retrieves an identifier stored in a memory card and obtains an image using the identifier. The memory card is physically coupled to the host device. The image identifies a content provider from which the host device receives broadcast content. The identifier routine is then executed by the host device to output the image.
