Innovation Solution
A method and apparatus that involve receiving signals, providing a primary and secondary path for digital video effects insertion, encoding, routing through a local area network, and modulating to form an output signal, utilizing a digital video effects module to insert effects into the primary path before encoding and multiplexing, ensuring reliable processing and integration into transport streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital video effects are inserted into television signals in satellite broadcasting systems, then the viewing experience is enhanced, but the reliability of signal processing becomes compromised
Solution Approach 1:
The system divides the signal processing into separate functional modules: a digital video effects insertion module that processes video signals to add effects, and a separate multiplexer that handles transport stream multiplexing. This segmentation allows each module to specialize in its function, improving both the ability to insert effects and the reliability of overall processing by isolating potential failure points.
Solution Approach 2:
The patent introduces an intermediary processing stage where digital video effects are inserted into video signals before they are multiplexed with audio and data streams. This intermediary module acts as a buffer between the effect insertion process and the final multiplexing operation, allowing effects to be applied reliably without disrupting the transport stream multiplexing process.
2Manufacturing precision
If digital video effects insertion is implemented in satellite broadcasting systems, then programming quality is improved, but system complexity increases
Solution Approach 1:
The digital video effects insertion module is designed as a universal component that can process multiple types of video signals and apply various effects through a single interface. This multi-functional approach improves programming quality across different channels while avoiding the need for separate effect insertion systems for each program, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system performs digital video effects insertion as a preliminary action before the multiplexing stage. By applying effects to video signals in advance and preparing them for multiplexing in a standardized format, the system improves programming quality without requiring complex real-time processing during the multiplexing operation itself.
