In-Vehicle Multimedia Streaming via Master Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle entertainment systems offer limited multimedia content choices, which become outdated quickly, and lack a common platform for third-party content providers and transportation service providers to offer personalized content to commuters, leading to an unpleasant ride experience due to the difficulty in browsing through a wide variety of available content.
Innovation Solution
A system and method that utilize first and second devices within a vehicle, connected through communication networks, to retrieve and stream multimedia files from internal memory and servers, with a master application acting as a common platform to rank and categorize content, providing personalized multimedia experiences to commuters by rendering online and offline applications developed by third-party providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimedia content is stored in internal memory or external storage devices, then the system structure is simple, but the content choice is very limited and gets outdated quickly
Solution Approach 1:
The patent introduces a server as an intermediary component that stores and manages multimedia content remotely. The in-vehicle entertainment system accesses this external server through a communication interface, allowing users to access a wide variety of up-to-date content without storing it locally. This resolves the contradiction by providing extensive content variety through the server while keeping the in-vehicle system structure relatively simple.
Solution Approach 2:
The patent transitions from local storage (one-dimensional, limited capacity) to cloud-based storage accessible via communication networks (adding a spatial dimension). By accessing content from a remote server through networks, the system gains access to virtually unlimited content variety without proportionally increasing local hardware complexity.
2Adaptability or versatility
If a wide variety of multimedia content is offered, then content freshness is improved, but it becomes difficult for commuters to browse and select content
Solution Approach 1:
The patent implements a recommendation engine that performs preliminary actions by analyzing user profiles, browsing history, and preferences to pre-select and recommend suitable content. This reduces the browsing burden on users while maintaining access to a wide variety of content, as the system proactively identifies and presents relevant options rather than requiring users to manually search through all available content.
Solution Approach 2:
The system incorporates feedback mechanisms that track user interactions with content (views, selections, ratings) and use this information to refine future recommendations. This creates a closed-loop system where content variety is maintained while selection ease improves through increasingly accurate personalized recommendations based on accumulated user feedback.
3Adaptability or versatility
If third-party content providers and transportation service providers operate independently, then system complexity is reduced, but personalized content delivery becomes difficult
Solution Approach 1:
The patent introduces a universal platform that serves multiple functions: it acts as a common interface for third-party content providers to upload content, a distribution network for transportation service providers to deliver content to vehicles, and a user profile management system for personalization. This multi-functional platform enables personalized content delivery while managing the complexity of integrating multiple independent providers through a single standardized interface.
Data Source
AI summary
A method and a system for providing in-vehicle services to commuters are provided. A first device transmits online and offline applications to a second device. The online and offline applications are rendered on the second device by way of a first master application installed on the second device. The first device receives one of a first or second request from the second device indicating a selection of an online or offline application, respectively. The first device retrieves one of a first multimedia file from a first memory of the first device in response to the first request or a second multimedia file from a first server in response to the second request. The first device streams one of the first or second multimedia file to the second device.
