Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern video systems are not effectively utilized when supporting lower resolution video streams from legacy standards, as they are designed to handle higher resolution video formats, leading to underutilization of memory and hardware.
Innovation Solution
A system and method for processing video data that combines lower resolution video frames to form a higher resolution video frame, using a frame processor to buffer and compile lower resolution frames, encode them, and a decoder to interpret metadata for efficient display, allowing flexible viewing modes and handling of multiple video streams within a single higher resolution frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the video system is designed to handle higher resolution video formats, then the maximum supported resolution is improved, but the system is not effectively utilized when supporting lower resolution video streams
Solution Approach 1:
The patent segments a single high-resolution frame into multiple lower-resolution sub-frames. By dividing the high-resolution frame into a grid of sub-frames, the system can process and transmit multiple lower-resolution video streams simultaneously within the same bandwidth, effectively utilizing the hardware capabilities while supporting legacy low-resolution standards.
Solution Approach 2:
The patent embeds multiple lower-resolution video frames within a single higher-resolution frame structure. Each lower-resolution frame is nested as a sub-frame within the high-resolution frame, allowing the system to handle multiple video streams concurrently without requiring separate processing pipelines, thus improving system utilization.
2Productivity
If multiple lower resolution video frames are combined to form a higher resolution video frame, then hardware utilization is improved, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-defining the segmentation scheme and metadata structure for combining multiple low-resolution frames into high-resolution frames. The system establishes the mapping relationships and processing rules in advance, which simplifies the actual processing workflow and reduces runtime complexity despite the increased hardware utilization.
Solution Approach 2:
The patent introduces metadata as an intermediary that manages the complexity of processing multiple video frames. The metadata contains information about the segmentation scheme, frame mappings, and processing parameters, allowing the system to handle complex multi-frame operations through a standardized interface without directly managing the complexity of each individual frame transformation.
3Adaptability or versatility
If lower resolution video streams are processed in higher resolution format, then display flexibility is improved, but the processing requirements increase
Solution Approach 1:
The patent implements dynamic processing where the system can adaptively choose to process video frames at different resolution levels based on the capabilities of the display device and the requirements of the application. The frame processor can dynamically adjust whether to combine multiple low-resolution frames or process single high-resolution frames, optimizing the use of processing power while maintaining display flexibility.
