IMS Gateway Device for Multimedia Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many electronic devices, both IMS-enabled and non-IMS-enabled, face limitations in receiving and rendering multimedia content and services due to format and quality restrictions, with IMS-enabled devices often unable to access content suited for devices with better display capabilities or connectivity.
Innovation Solution
A mobile electronic device acts as a gateway to receive multimedia content from an IMS network, convert it to a different format, and transmit it over a local network to other devices, including non-IMS-enabled devices, allowing decentralized IMS server functionality and improved quality of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-IMS-enabled electronic device is used to receive multimedia content, then device compatibility and accessibility are improved, but the device cannot directly access IMS services and content
Solution Approach 1:
The patent employs an IMS-enabled gateway device as an intermediary between the IMS network and non-IMS-enabled electronic devices. The gateway receives IMS multimedia content and services, converts them to appropriate formats, and transmits them over a local network to devices that cannot directly access IMS services, thereby enabling universal access while maintaining service reliability
Solution Approach 2:
The gateway device performs format conversion by changing the parameters of multimedia content (such as encoding format, resolution, and protocol) to make it compatible with non-IMS-enabled devices. This parameter transformation allows the same content to be delivered to devices with different capabilities without compromising the original service quality
2Adaptability or versatility
If an IMS-enabled device with limited display capabilities receives multimedia content, then service accessibility is improved, but content quality and presentation are restricted
Solution Approach 1:
The gateway device applies local quality adaptation by tailoring the output content quality to match the specific capabilities of each receiving device. It analyzes the target device's display characteristics and adjusts the multimedia content's resolution, format, and quality parameters accordingly, ensuring optimal presentation for each device type while maintaining accessibility across different capabilities
3Productivity
If multimedia content is transmitted directly from the IMS network to all devices, then network efficiency is improved, but devices with incompatible formats cannot receive content
Solution Approach 1:
The gateway device serves as a mediation point in the content delivery path. Instead of requiring the IMS network to directly support all possible device formats, the gateway receives content in the native IMS format and performs format conversion locally, thereby maintaining network efficiency while achieving universal format compatibility
Solution Approach 2:
The gateway device creates format copies of the original IMS content, generating versioned copies in different formats suitable for various devices. This copying approach allows the original content to remain unchanged in the IMS network while providing device-specific adapted versions to end users
4Adaptability or versatility
If a gateway device performs format conversion, then device compatibility is improved, but processing time and complexity increase
Solution Approach 1:
The gateway device performs format conversion in advance before content delivery to the end device. By pre-processing the content and having converted versions ready, the actual delivery time to the user is minimized, and the processing overhead is distributed over time rather than occurring in real-time during content playback

AI summary
This disclosure relates to techniques, devices, and systems for using a mobile electronic device to provide multimedia content. One example method of providing multimedia content includes receiving, at an Internet Protocol Multimedia Subsystem (IMS) enabled first electronic device, multimedia content from a content-providing electronic device via an IMS network, where the multimedia content has a first format. The method also includes converting, at the IMS-enabled first electronic device, the multimedia content from the first format to a second format that is different from the first format. The method further includes transmitting, from the IMS-enabled first electronic device to a second electronic device, the converted multimedia content in the second format, where the converted multimedia content is transmitted from the first electronic device to the second electronic device via a local network that is different from the IMS network.
