Set-Top Box Metadata Bypass for UHD Broadcast Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital broadcasting systems, such as MPEG-2 TS, are inefficient for delivering high-data-rate content like UHD broadcasting and struggle to preserve metadata during content delivery to users' TVs, often losing metadata during processing in set-top boxes.
Innovation Solution
A method and apparatus that include metadata in a compressed audio stream, allowing it to be bypassed through set-top boxes without decoding, enabling extraction and processing by TVs to deliver additional services by obtaining and playing back media data using metadata information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If metadata is included in compressed audio stream and bypassed through set-top box, then metadata delivery to TV is improved, but device complexity increases
Solution Approach 1:
The system separates metadata handling from audio decoding by extracting metadata from the compressed audio stream and routing it through a dedicated metadata processor path, while the audio data itself continues through the traditional decoding path. This segmentation allows metadata to be delivered to the TV without requiring full audio decoding at the set-top box.
Solution Approach 2:
A metadata processor is introduced as an intermediary component that intercepts the compressed audio stream, extracts metadata, and forwards it separately to the TV. This intermediary handles the metadata delivery function without requiring the set-top box to perform full audio decoding, thus reducing device complexity while improving metadata delivery.
2Adaptability or versatility
If additional services are enabled through metadata processing, then adaptability is improved, but device complexity increases
Solution Approach 1:
The TV device is enhanced with built-in metadata processing capability, allowing it to self-serve by extracting and processing metadata directly from the received compressed audio stream. This enables the TV to provide additional services such as displaying metadata information or using it for service selection without requiring complex processing at the set-top box.
Solution Approach 2:
The system adds a new dimension of functionality by enabling the TV to process and utilize metadata independently from the audio playback function. This dimensional separation allows the TV to provide additional services based on metadata while the set-top box maintains its simpler audio transmission role.
