Media Capability Merging Across Chained Display and Audio Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media systems with multiple devices from different manufacturers face challenges in coordinating their capabilities to achieve improved multimedia experiences due to varying image resolutions and sound qualities.
Innovation Solution
A display device in the system identifies and modifies its media capability data block to include information from a downstream device, reporting a combined media capability to the source device for enhanced multimedia content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple media devices from different manufacturers are coupled together, then improved user experiences with better sound or picture can be achieved, but coordinating the multiple media devices with different capabilities becomes challenging
Solution Approach 1:
The display device acts as an intermediary between the source media device and the downstream media device. It receives capability information from the downstream device, modifies its own capability data block to reflect combined capabilities, and reports this modified data to the source device. This intermediary approach simplifies coordination by providing a unified capability interface rather than requiring direct complex interactions between all devices.
Solution Approach 2:
The display device merges its own media capabilities with those of the downstream media device by modifying its capability data block. It replaces default capability information with combined capability information that reflects the aggregate capabilities of both devices, enabling the source device to treat them as a unified system with enhanced capabilities.
2Loss of information
If the display device reports its default capability alone, then the capability data block remains simple, but the source device cannot provide content optimized for the combined capabilities of multiple devices
Solution Approach 1:
The display device performs preliminary action by proactively modifying its capability data block before the source device requests capability information. It anticipates the need to report combined capabilities and prepares the modified data block in advance, ensuring complete capability information is available when the source device queries it.
Solution Approach 2:
The display device implements feedback by receiving capability information from the downstream media device and using it to update its own capability representation. This feedback loop ensures that the capability data block accurately reflects the combined capabilities of the display device and downstream device, providing complete information to the source device.

AI summary
Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a media device receiving from a source media device a request about a media capability of the media device, and identifying a data block indicating a default capability of the media device. The media device can further select a data unit of the data block to be replaced based on a media capability of a downstream media device attached to the media device. Afterward, the media device can modify the data block by replacing the selected data unit by information indicating the media capability of the downstream media device to generate a modified data block to represent a combined media capability of the media device and the downstream media device. In addition, the media device can send the modified data block to the source media device.
