Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multiplexing devices face limitations in processing large image data, leading to segmentation or abandonment issues, which disrupt proper multiplexing and decoding due to constraints on hardware, and often result in out-of-order delimitation of video packets.
Innovation Solution
A multiplexing device with a data conversion unit that segments or concatenates input data to maintain a predetermined size, ensuring proper handling and delimitation, and includes adaptation units for voice and control data to optimize multiplexing efficiency by adjusting data sizes according to specific maximum sizes and headers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data of large size is input to the multiplexing device, then the device cannot properly process the data due to hardware constraints, but simply abandoning or segmenting the data disrupts proper multiplexing and decoding
Solution Approach 1:
The patent segments large image data into multiple smaller data units that can be processed by the multiplexing device. The data conversion unit divides the input image data into a plurality of data units, each with size not exceeding the predetermined limit, while maintaining the original data integrity and order for proper multiplexing and decoding.
Solution Approach 2:
The patent performs preliminary segmentation of image data before the multiplexing process. The data conversion unit pre-processes the large image data by dividing it into manageable units, ensuring that the subsequent multiplexing operation can handle the data properly without causing overflow or loss of information.
2Productivity
If image data is segmented to fit hardware constraints, then the data can be processed, but the delimitation of video packets becomes out-of-order
Solution Approach 1:
The patent segments image data while preserving packet delimitation information. The data conversion unit divides the image data into multiple units but maintains the original packet boundaries and delimitation markers, ensuring that video packets remain in the correct order and can be properly decoded after multiplexing.
Solution Approach 2:
The patent applies different handling to different parts of the image data based on their packet boundaries. The data conversion unit respects the local structure of video packets by maintaining delimitation information at packet boundaries, ensuring that each segment retains its identity and ordering information for accurate reconstruction.
3Reliability
If the multiplexing device processes data without size constraints, then data overflow can be avoided, but hardware limitations prevent proper processing of large data
Solution Approach 1:
The patent segments large data into smaller units that fit within hardware processing constraints. The data conversion unit divides image data into multiple data units, each with size not exceeding the predetermined limit, allowing the multiplexing device to process the data reliably without causing overflow while working within hardware limitations.
Data Source
AI summary
The multiplexing device includes a data conversion unit which receives input of at least one of a plurality of pieces of data and executes segmentation or concatenation processing with respect to the data as required to output data which fails to exceed a predetermined limited size and which is delimited by a delimitation of a predetermined data unit, a plurality of adaptation units which are disposed in plural corresponding to the plurality of pieces of data and output data from the data conversion unit to provide the corresponding data with a function of an adaptation layer according to properties of the data, and a multiplexing layer unit which multiplexes a plurality of pieces of data from the plurality of adaptation units and sends out the multiplexed data.
