Composite Multimedia Signal Encoding for Single Medium Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia signal processing and transmission systems require multiple transmission mediums, leading to inefficient use of resources and increased costs, as they struggle to effectively process and transmit signals from multiple channels.
Innovation Solution
The system generates a composite multimedia signal by coding multiple signals in a frame format with an active zone for encoding signals and a blanking zone for format information, converting part of the signal into analog for efficient transmission over a single medium, suitable for long-distance transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission mediums are used to transmit multimedia signals from multiple channels, then signal transmission reliability is improved, but transmission resource efficiency deteriorates and costs increase
Solution Approach 1:
The patent combines multiple multimedia signals from different channels into a single composite signal that can be transmitted over one transmission medium. The processing device receives first and second multimedia signals, encodes them separately, then combines them into a composite signal containing both encoded signals, which is then modulated and transmitted over a single medium, reducing resource waste while maintaining transmission reliability
Solution Approach 2:
The transmission medium is made multi-functional by enabling it to carry multiple encoded multimedia signals simultaneously through a single composite signal structure. The composite signal can accommodate multiple encoded signals from different channels, allowing one transmission medium to perform the function of multiple separate transmission channels
2Reliability
If multiple transmission mediums are used for multimedia signals, then signal quality is maintained, but device complexity and transmission cost increase
Solution Approach 1:
The patent merges multiple transmission paths into a single composite transmission path. Instead of using separate transmission mediums for each multimedia signal, the system combines multiple encoded signals into one composite signal that travels over a single medium, simplifying the transmission system architecture while preserving signal quality through proper encoding and combining
Solution Approach 2:
The patent segments the composite signal into distinct encoded portions for different multimedia signals, allowing them to be transmitted together yet remain separable. The composite signal contains multiple encoded signals that can be individually processed and decoded at the receiving end, maintaining signal quality while reducing system complexity
3Quantity of substance
If multiple transmission mediums are used, then transmission capacity is sufficient, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent merges multiple transmission channels into a single composite transmission stream. By combining multiple encoded multimedia signals into one composite signal that occupies a single transmission medium, the system achieves the same total transmission capacity as multiple separate channels while dramatically improving resource utilization efficiency and eliminating the waste of unused transmission capacity in separate channels
