Solution Overview
Problem
Current media delivery systems require decoding of media programs at the display device, which can be inconvenient and limit the flexibility in media content distribution, especially in mobile communication scenarios where network capabilities and device interconnectivity are expanding.
Innovation Solution
A mobile communication device with a processor that receives a media stream, detects display devices, establishes wireless communication links, and decodes selected media programs for transmission to display devices without requiring decoding at the display device, allowing seamless media content distribution and user interface management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media programs are decoded at the display device, then the display device can independently present media content, but the system complexity and decoding requirements at the display device increase
Solution Approach 1:
The patent extracts the decoding function from the display device and relocates it to a mobile communication device. The mobile device receives encoded media streams, decodes them using its processing capabilities, and transmits the decoded content to the display device for presentation. This extraction eliminates the need for the display device to have decoding capabilities, thereby reducing its complexity while maintaining media distribution flexibility.
Solution Approach 2:
The mobile communication device serves as an intermediary between the media source and the display device. It receives media streams, performs decoding operations, and then relays the decoded content to the display device. This intermediary approach allows the system to maintain flexibility in media distribution while offloading the complex decoding task from the display device to a device specifically designed for such operations.
2Device complexity
If decoding is performed at the mobile communication device, then the display device can be simpler, but the mobile device must establish additional wireless communication links
Solution Approach 1:
The mobile communication device autonomously performs the decoding operation without requiring the display device to have decoding capabilities or to establish complex communication protocols for decoding. The mobile device uses its own processing resources to decode media streams and then transmits the results to the display device, which only needs to handle simple presentation tasks. This self-service approach simplifies the display device while the mobile device's advanced capabilities handle the additional communication requirements.
