IP-Augmented Television Streams with Synchronized Quality Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcast television networks face challenges in maintaining high-quality video content delivery due to bandwidth limitations, resulting in lower quality video being broadcast over dedicated networks, while internet-based solutions lack integration with traditional TV systems.
Innovation Solution
A method is introduced where satellite television servers encode original video streams into compressed streams with augmentation streams over the internet to enhance quality, using synchronization data to align the streams and reduce data transmission inefficiencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video streams are compressed for broadcast over satellite television networks, then bandwidth efficiency is improved, but video quality deteriorates due to lost data
Solution Approach 1:
The video stream is segmented into two separate streams: a compressed broadcast stream for wide distribution and an augmentation stream containing lost data for quality enhancement. This segmentation allows each stream to be optimized for its specific purpose while working together to deliver high quality video.
Solution Approach 2:
The augmentation stream acts as an intermediary that bridges the gap between the compressed broadcast stream and the original high quality video. It carries the lost data that, when combined with the broadcast stream, reconstructs the original video quality.
2Manufacturing precision
If augmentation streams are transmitted over the Internet to enhance video quality, then video fidelity is improved, but network complexity increases
Solution Approach 1:
The system is designed to work with existing broadcast and Internet infrastructure, making both networks serve multiple functions. The broadcast network delivers the compressed stream while the Internet delivers the augmentation stream, allowing users to leverage their current setup for enhanced video quality.
Solution Approach 2:
The receiver device automatically performs the combination of the broadcast stream and augmentation stream, and the synchronization process is handled through embedded timing data in the augmentation stream packets, reducing the need for complex external synchronization infrastructure.
3Measurement precision
If synchronization data is added to augmentation streams, then stream alignment is improved, but data transmission volume increases
Solution Approach 1:
Synchronization data is embedded locally within individual augmentation stream packets rather than requiring separate synchronization messages. Each packet contains timing information specific to its content, allowing precise alignment without additional overhead communication.

AI summary
Techniques for augmenting IP television streams are presented herein. In some techniques, an original video stream is encoded as a compressed video stream by a satellite television system and broadcast via a satellite television network. The lost data resulting from encoding the original video stream as the compressed video stream is encoded as an augmentation video stream and transmitted to a remote device via the Internet in response to a request from the remote device received by the satellite television system via the Internet to enhance the compressed video stream with the augmentation video stream.
