Problem
Conventional satellite communication systems face challenges in transmitting high-definition and advanced services at enhanced data rates while adhering to cost-effectiveness, power consumption constraints, and maintaining efficiency, particularly in supporting high bandwidth and interactive services compliant with the DVB-S2 Standard.
Innovation Solution
A dynamic and flexible multiplexing scheme that allows terminals to operate on wideband signals without requiring full-speed decoding, achieved through Time Division Multiplexing (TDM) or Code Division Multiplexing (CDM), enabling multiple times greater data capacity by aggregating multiple conventional information streams into a single high-rate aggregate stream.

Engineering Contradiction Analysis
1Productivity
If conventional satellite communication systems use traditional modulation and coding mechanisms to support high data rates, then data throughput is improved, but device complexity and power consumption increase significantly
Solution Approach 1:
The patent segments the data stream into multiple sub-streams with different modulation and coding schemes. Each sub-stream can be processed independently at appropriate rates, allowing the system to achieve high overall throughput without requiring all processing components to operate at maximum complexity levels simultaneously.
Solution Approach 2:
The patent implements dynamic adaptation where the modulation and coding schemes can be adjusted based on channel conditions and service requirements. This allows the system to optimize between data throughput and processing complexity in real-time, rather than being locked into a single high-complexity configuration.
2Productivity
If conventional satellite systems use traditional modulation mechanisms to achieve high data rates, then data throughput is improved, but power consumption increases significantly
Solution Approach 1:
By dividing the data stream into multiple sub-streams processed at different rates, the system reduces the total processing power required. Lower-rate processing of individual sub-streams consumes less energy than processing the entire stream at high rate, while still achieving high overall throughput through parallel processing.
Solution Approach 2:
The patent changes the processing rate parameter for different sub-streams based on their importance and channel conditions. This allows optimization of power consumption by processing critical data at higher rates and less critical data at lower rates, rather than uniformly processing all data at maximum rate.
3Productivity
If satellite systems transmit high-definition and advanced services at enhanced data rates, then service quality is improved, but loss of information increases due to channel errors
Solution Approach 1:
The patent applies different modulation and coding schemes to different sub-streams based on their specific quality requirements. Critical services receive higher-rate processing with enhanced error protection, while less critical services use lower-rate processing, optimizing the balance between throughput and error protection for each service type.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor channel conditions and service quality, allowing dynamic adjustment of modulation and coding schemes. This feedback enables the system to adapt to changing conditions and maintain optimal performance while minimizing information loss.
4Productivity
If conventional transmitter equipment is used to support high data rates, then data throughput is improved, but ease of manufacture decreases due to expensive equipment requirements
Solution Approach 1:
The patent enables high throughput using multiple lower-rate processing units instead of a single high-rate unit. This segmentation allows the system to be manufactured using more cost-effective, lower-rate equipment that can be produced in greater quantities and at lower cost, while achieving the same overall throughput through parallel processing.
Solution Approach 2:
The system uses universal processing components that can handle multiple service types and data rates through software configuration rather than requiring specialized hardware for each service. This multi-functionality reduces manufacturing complexity and cost by using a single platform for diverse applications.

AI summary
A system for a dynamic and flexible multiplexing scheme to allow terminals of a communications system to operate on wideband signals without requiring the operation at full speed, and under multiclass terminal operation, is provided. According to the multiplexing scheme, a one codeblock of a plurality of codeblocks within a multiplexed datastream is decoded, wherein each codeblock includes a flag that indicates whether the codeblock contains a timeplan, and the timeplan signifies a multiplexing structure of the datastream. A determination is made as to whether the flag of the one codeblock indicates that the one codeblock contains the timeplan, and, if it is determined that the one codeblock contains the timeplan, the timeplan is acquired. Further, in response to a determination that the one codeblock does not contain the timeplan, a first subsequent codeblock is determined, and decoded. Each codeblock further includes a sequence number indicator that indicates a sequence position of the one codeblock within a first group of the codeblocks of the multiplexed datastream, and the first subsequent codeblock is determined based on one or more of a decode rate of the processor device and the sequence number indicator A determination is made as to whether the flag of the first subsequent codeblock indicates that the first subsequent codeblock contains the timeplan, and, if it is determined that the first subsequent codeblock contains the timeplan, the timeplan is acquired.
