Media Capability Merging Across Chained Display 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 its default capability and that of an attached downstream device, generating a combined media capability by modifying a data block to include the downstream device's capabilities, which it reports to a source device for enhanced content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple media devices from different manufacturers are coupled together, then improved multimedia experiences can be achieved through combined capabilities, but coordination challenges arise due to varying image resolutions and sound qualities
Solution Approach 1:
The media capability information is segmented into discrete data blocks with specific data units that can be individually modified. Each device reports its capabilities in structured segments (data blocks containing data units) that can be processed and combined systematically, reducing the complexity of coordinating heterogeneous devices.
Solution Approach 2:
The display device dynamically changes the capability parameters by modifying data units within data blocks. It replaces default capability data with actual combined capabilities based on what is detected from downstream devices, allowing the system to adapt parameters (image resolution, sound quality) to match the actual hardware configuration.
2Reliability
If a display device reports its default capability to a source device, then the source device can generate appropriate multimedia content, but the capability may not reflect the actual combined capabilities of attached downstream devices
Solution Approach 1:
The display device performs preliminary detection of downstream device capabilities and pre-modifies its capability data blocks before the source device requests content. By preparing the accurate combined capability information in advance (replacing data units with actual capabilities), the system ensures reliable capability reporting when the source device queries, improving both accuracy and subsequent content delivery efficiency.
Solution Approach 2:
The system implements a feedback mechanism where the display device detects the actual capabilities of downstream devices and uses this information to update its reported capability profile. This feedback loop ensures that the capability information reported to the source device accurately reflects the combined capabilities of the entire media chain, enabling reliable content generation.

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.
