Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy digital devices face challenges in quickly booting and providing efficient access to MVPD services due to embedded set-top box solutions, leading to increased loading times and user inconvenience, especially when supporting MVPD services on web OS platforms.
Innovation Solution
A method for digital devices that involves loading and executing a first image control application for minimum functions upon power-on, followed by a second image control application with additional functions in the background, while managing resources to enhance booting speed and supporting RF and IP-based MVPD services, similar to external inputs like HDMI, to provide seamless service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a legacy MVPD service with embedded set-top box solutions is implemented in a digital device, then the service functionality is complete, but the booting time and service loading time increase significantly
Solution Approach 1:
The image control application is divided into two separate applications: a first image control application providing minimum image control functions and a second image control application providing various image control functions. This segmentation allows the system to boot with only the essential first application, significantly reducing booting time while maintaining the option to load the second application for enhanced functionality when needed.
Solution Approach 2:
The first image control application is pre-configured to provide minimum image control functions that are sufficient for basic operation. This preliminary setup allows the device to become operational quickly without waiting for the more comprehensive second application to load, thereby reducing the perceived booting time for users.
2Speed
If a first image control application providing minimum functions is executed at power-on, then the booting speed is improved, but the image control functionality is limited
Solution Approach 1:
The system dynamically switches between the first image control application for minimum functions during booting and the second image control application for various functions. The controller is configured to terminate the first application and execute the second application after the second application is loaded, providing adaptive functionality that meets both speed and versatility requirements at different operational stages.
3Adaptability or versatility
If a second image control application with various functions is loaded in the background, then the image control versatility is improved, but the resource management complexity increases
Solution Approach 1:
The controller acts as an intermediary that manages the loading and switching between the first and second image control applications. It automatically terminates the first application and executes the second application after loading, simplifying the resource management process by providing a clear transition mechanism that reduces the complexity of managing multiple applications with different functionality levels.
4Ease of operation
If MVPD services are supported on a web OS platform, then the service accessibility is improved, but the service loading time increases
Solution Approach 1:
By segmenting the image control application into two separate applications with different functionality levels, the system can load only the essential first application during booting on the web OS platform. This segmentation enables faster service accessibility while maintaining the option to load the more comprehensive second application for enhanced MVPD service functionality when required.
