Multimedia Content Delivery Adaptation for Mobile Device Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to reliably deliver multimedia content to mobile devices across different carriers and devices due to interoperability issues, variability in device capabilities, and proprietary protocols, making it challenging to identify supported media formats and delivery protocols, which is critical for just-in-time training of first responders.
Innovation Solution
A computer system that uses user involvement to determine device capabilities through profiling methods like smart echo and SMS-initiated profiling, allowing it to adapt and deliver multimedia content in formats supported by each device, regardless of carrier or device type, by sending test messages and relying on user feedback for optimal format selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Internet-based systems are used to deliver multimedia content to mobile devices, then content delivery is possible, but reliability is poor due to limited device video capability and microbrowser architecture
Solution Approach 1:
The patent introduces an MMS gateway as an intermediary between the content delivery system and mobile devices. This gateway acts as a mediator that handles format conversion and delivery protocol adaptation, allowing reliable content delivery without requiring direct compatibility between the delivery system and diverse mobile devices. The gateway receives content requests, determines appropriate formats based on device capabilities, and delivers content through MMS protocols that have broad device support.
Solution Approach 2:
The system dynamically changes content parameters (format, encoding, delivery protocol) based on detected device capabilities. Instead of using a fixed delivery method, the system adapts content parameters to match the specific capabilities of each mobile device, such as selecting between video formats, audio formats, or alternative representations based on what the device can process.
2Adaptability or versatility
If proprietary protocols and service provider-specific approaches are used, then service provider control is improved, but interoperability between different carriers and devices deteriorates
Solution Approach 1:
The patent employs MMS (Multimedia Messaging Service) as a universal delivery mechanism that works across multiple service providers and device types. MMS is a standardized protocol with broad industry support, allowing the system to deliver content universally without requiring separate implementations for each carrier or device type. This multi-functional approach enables a single content delivery infrastructure to serve diverse platforms.
Solution Approach 2:
The MMS gateway serves as an intermediary that translates between different service provider protocols and the standardized MMS format. This mediator layer handles protocol conversion, allowing the system to maintain interoperability across carriers while managing the complexity of protocol variability centrally rather than requiring each component to support all protocols directly.
3Measurement precision
If device profiling through user feedback is implemented, then content format adaptation is improved, but system complexity increases
Solution Approach 1:
The system implements a feedback mechanism where user responses to content delivery are used to refine device capability profiles. When content is delivered to a device, the system monitors whether the content is successfully rendered and uses this feedback to improve future format selections for that device type. This iterative feedback process gradually builds accurate capability profiles without requiring complex upfront device characterization.
Solution Approach 2:
The device profiling system operates in a self-service manner where the system automatically detects and learns device capabilities through actual content delivery attempts and user responses, rather than requiring manual device registration or complex user-provided information. The system serves itself by using real-world delivery outcomes to automatically refine its understanding of device capabilities.

AI summary
A content delivery system, such as a Just in Time Training (JITT) system which allows the broadcast of multimedia messages to recipients or users. The JITT system identifies the multimedia capabilities as well as the capabilities of the service provider and recipient device for each user and uses this profile information to determine an appropriate messaging format to use to send the message to each user. User involvement is used to determine the functionality and content type delivery for each user mobile device. This profiling may be performed in any of a number of different ways, including smart echo, caller-ID initiated (CIDI) and SMS initiated (SMSI) profiling. In smart echo profiling, the user sends the JITT system a multimedia sample from the mobile device, and the JITT system then sends messages and content to the mobile devise using the same format. In CIDI profiling, the JITT system sends test messages in different formats to the phone number of the device, and the user replies to the message having the best audiovisual experience. The system then uses the format associated with the reply message for further communications with the user. SMSI profiling is similar to CIDI profiling, except that the user sends an SMS instead of making a call. Users with multimedia recording devices, such as camera phones, can also upload multimedia through this system for subsequent broadcast. Users with data recording devices, such as toxic gas sensors, can also upload data through this system for subsequent conversion to multimedia and broadcast.
