Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional satellite systems face challenges in transmitting and receiving high-quality video and advanced data services at enhanced data rates, requiring expensive equipment with high power consumption, while also needing to improve efficiency and reduce complexity and cost, while remaining compliant with the DVB-S2 Standard.
Innovation Solution
A dynamic and flexible multiplexing scheme that allows terminals to operate on wideband signals without requiring the decoder to operate at full speed, by decoding and demultiplexing codeblocks with flags indicating the presence of a timeplan, and using sequence number indicators to determine the correct codeblocks for decoding, enabling multiclass terminal operation and efficient bandwidth allocation.

Engineering Contradiction Analysis
1Productivity
If conventional satellite systems transmit high-quality video and advanced data services at enhanced data rates, then data capacity is improved, but equipment cost and power consumption increase significantly
Solution Approach 1:
The patent segments the data stream into multiple codeblocks with different priority levels and service types. By dividing the transmission into discrete, manageable codeblocks that can be independently decoded, the system achieves high data capacity while allowing receivers to selectively decode only necessary portions, reducing overall power consumption requirements
Solution Approach 2:
The patent implements dynamic bandwidth allocation and flexible multiplexing schemes where codeblocks can be dynamically assigned to different services and priority levels. This dynamic approach allows the system to adapt to varying data rate requirements without requiring permanently high-power transmission equipment, achieving enhanced data capacity with reduced power consumption
2Productivity
If conventional satellite systems transmit high-quality video and advanced data services at enhanced data rates, then data capacity is improved, but equipment complexity and cost increase
Solution Approach 1:
By segmenting the data stream into standardized codeblocks with clear structure and flags, the patent simplifies the receiver architecture. Terminals can use uniform decoding processes for each codeblock type, reducing equipment complexity while achieving high data capacity through efficient multiplexing of multiple services
Solution Approach 2:
The patent changes key transmission parameters including codeblock structure, flag indicators, and multiplexing schemes to optimize for both high capacity and low complexity. By standardizing codeblock formats and using parameter-based service identification, the system achieves enhanced data rates without requiring complex terminal equipment
3Productivity
If terminals decode all codeblocks at full speed to handle wideband signals, then data capacity is improved, but power consumption and processing complexity increase
Solution Approach 1:
The patent segments the data stream into codeblocks with priority indicators and service-specific flags. Terminals can decode only the necessary codeblocks at full speed while handling others at reduced rates or skipping them entirely, achieving high data capacity without requiring all terminals to operate at maximum decoder speed
Solution Approach 2:
The patent enables partial decoding where terminals process only the subset of codeblocks relevant to their service requirements at full speed, while other codeblocks can be processed at lower rates or skipped. This partial action approach achieves high effective data capacity without the excessive power consumption and complexity of full-speed universal decoding

AI summary
A system for a multiplexing scheme for wideband signals in a communications system is provided. A codeblock of a multiplexed datastream is decoded. The codeblock includes a flag indicating whether the codeblock contains a timeplan, signifying a multiplexing structure of the datastream. A determination is made whether the flag indicates the presence of the timeplan, and, if so, the timeplan is acquired. In response to a determination that the codeblock does not contain the timeplan, a subsequent codeblock is determined, and decoded. Each codeblock includes an indicator of a sequence position of the codeblock within a group of codeblocks of the datastream. The subsequent codeblock is determined based on one or more of a decode rate of the processor device and the sequence position indicator. A determination is made whether the flag of the subsequent codeblock indicates the presence of the timeplan, and, if so, the timeplan is acquired.
