Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital TV receivers face challenges in seamlessly integrating alternative video and audio content (AVA) with main video and audio content (MVA) of linear origin, leading to synchronization issues and viewer experience disruptions, particularly in digital terrestrial TV systems that require backward compatibility and adherence to specific standards.
Innovation Solution
A system and method for synchronized, dynamic replacement of MVA programming blocks with AVA, using DSMCC signaling and a decision-making center to ensure smooth transitions based on receiver conditions, ensuring compatibility and viewer experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If alternative video and audio content (AVA) is integrated with main video and audio content (MVA) of linear origin, then content personalization and viewer experience are improved, but synchronization issues and system complexity increase
Solution Approach 1:
The MVA content stream is divided into discrete programming blocks that can be individually replaced with AVA content. The system segments the linear content into replaceable units, allowing selective substitution without affecting the entire stream, thus managing complexity while enabling personalization.
Solution Approach 2:
A decision-making center acts as an intermediary between the MVA source and the output, evaluating receiver conditions and determining whether to replace programming blocks with AVA content. This mediator coordinates synchronization and manages the complexity of integrating multiple content sources.
2Adaptability or versatility
If dynamic replacement of MVA programming blocks with AVA is implemented, then content flexibility and viewer personalization are improved, but synchronization stability deteriorates
Solution Approach 1:
The system evaluates receiver conditions (CPU usage, RAM resources, storage capacity, bandwidth, resolution) in advance before replacing programming blocks. This preliminary evaluation ensures that replacements occur only when conditions are favorable, maintaining synchronization stability while enabling flexibility.
Solution Approach 2:
The decision-making center continuously monitors receiver operation conditions and uses this feedback to dynamically adjust replacement decisions. This closed-loop control maintains synchronization stability by adapting to changing system conditions in real-time.
3Manufacturing precision
If receiver conditions are evaluated before AVA display, then content replacement quality is improved, but processing time and operational complexity increase
Solution Approach 1:
The system evaluates only the necessary receiver conditions (CPU usage, RAM, storage, bandwidth, resolution) required for successful AVA playback, rather than进行全面 system analysis. This partial evaluation approach maintains replacement quality while minimizing processing time overhead.
4Ease of operation
If display transition control is implemented to ensure synchronism, then viewer experience continuity is improved, but control mechanism complexity increases
Solution Approach 1:
The display transition control functionality is merged with the existing programming block replacement mechanism. The decision-making center that determines content replacement also manages the transition timing and synchronization, consolidating control functions rather than adding separate complex control systems.

AI summary
The present disclosure relates to a system implemented in a digital TV receiver that provides a broadcaster with a reliable method of ingesting alternative video and/or audio content received through a broadband connection, replacing parts of the main video and/or audio content, received from the broadcast transmission signal, aiming to customize the consumer's experience during digital video and/or audio consumption. The system regularly evaluates the digital TV receiver's environment parameters that may vary at any time, as well as its connection to the Internet. Sufficient requirements for the replacement process are met, namely the quality and completeness required for reproducing the alternative video and/or audio content, so as to provide success and quality of such reproduction, improving consumer experience without experiencing failures, interruptions, lack of fluidity or lack of consistency, effectively equating the consumption experience of the alternative content to the same level of quality standard as the main content.
