DLNA Media Control Device Metadata Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with non-fully compliant DLNA operating systems, such as iOS and tvOS, face challenges in obtaining stream media content information from DLNA-compatible devices due to lack of full compatibility, leading to inefficient media playback and increased processing overhead.
Innovation Solution
A media control device interprets DLNA HTTP requests, identifies metadata indicating stream media content information, and sends a DLNA HTTP response with metadata in base64 format, enabling construction of an HLS master playlist and reducing the need for deep inspection and decryption, facilitating communication between non-fully compliant devices and DLNA-compatible devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-fully compliant devices (iOS/tvOS) attempt to obtain stream media content information from DLNA-compatible devices using standard DLNA protocols, then compatibility with DLNA ecosystem is maintained, but processing overhead increases and playback efficiency decreases due to lack of full compatibility
Solution Approach 1:
The patent introduces an intermediary mechanism where the DLNA-compatible device acts as a mediator by providing a standardized interface that translates and exposes stream media content information in a format compatible with non-fully compliant devices. This intermediary layer allows iOS/tvOS devices to access stream metadata without requiring full DLNA protocol implementation, thus maintaining ecosystem compatibility while improving streaming efficiency through optimized data exchange.
2Loss of information
If non-fully compliant devices perform deep inspection and decryption of stream content to obtain metadata, then complete stream information can be extracted, but processing overhead increases significantly
Solution Approach 1:
The patent applies the extraction principle by having the DLNA-compatible device extract and provide only the necessary stream media content metadata through a standardized interface, rather than requiring non-fully compliant devices to perform deep inspection and decryption of the entire stream content. This selective extraction of required information reduces processing overhead while maintaining completeness of essential stream metadata for playback.
3Ease of operation
If DLNA-compatible devices provide detailed stream metadata through standard DLNA interfaces, then non-fully compliant devices can achieve full playback functionality, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a standardized interface that serves multiple functions: it provides stream media content information to non-fully compliant devices while maintaining compatibility with the DLNA ecosystem. This universal interface allows a single DLNA-compatible device to serve both fully compliant DLNA devices and non-fully compliant devices (iOS/tvOS) without requiring separate complex interfaces, thus improving playback functionality while managing device complexity.

AI summary
Technologies are disclosed for providing stream media content and/or metadata indicating stream media content. A media control device may receive a Digital Living Network Alliance (DLNA) hypertext transport protocol (HTTP) request from a media content device. The DLNA HTTP request may have a header created by the media content device. The media control device may interpret the DLNA HTTP request header. A first metadata may be identified in the DLNA HTTP request header that may indicate a request for stream media content information. The media control device may send a DLNA HTTP response to the media content device. The DLNA HTTP response may have a header that may include a second metadata indicating the stream media content information. The second metadata may include information enabling construction of a HTTP Live Streaming (HLS) master playlist, a program map table, and/or a program association table associated with the stream media content.
