Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing asymmetric image splitter systems require complex design coordination between vendors and increased memory usage due to the need for synchronized transmitter and receiver configurations, which limits flexibility and increases costs in applications like automotive infotainment and ADAS.
Innovation Solution
Implementing a system with a line mark memory and asymmetric image splitter using GMSL technology that allows for flexible design by vendors, reducing memory requirements through the use of a programmable line mark memory to manage padding and video clock frequencies, enabling efficient splitting and transmission of multi-image streams across different display resolutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If asymmetric image splitter uses synchronized transmitter and receiver configurations, then design coordination between vendors is improved, but device complexity and memory requirements increase
Solution Approach 1:
The patent segments the image data into multiple independent image streams (e.g., first image, second image, third image) that can be processed separately. Each image stream is transmitted independently through the serializer, allowing the receiver to reconstruct images without requiring complex synchronized coordination between vendors. This segmentation reduces the memory requirements and device complexity while maintaining reliable multi-image transmission.
Solution Approach 2:
The asymmetric image splitter is designed to handle multiple different image resolutions and formats simultaneously using a universal processing framework. The serializer can accommodate various image sizes (e.g., different heights and widths) without requiring different hardware configurations, reducing vendor coordination complexity while supporting diverse display requirements.
2Adaptability or versatility
If asymmetric image splitter supports multiple display resolutions, then system flexibility is improved, but memory requirements increase
Solution Approach 1:
The patent implements dynamic image stream processing where the serializer can adaptively handle different image resolutions and formats in real-time. The system dynamically adjusts the processing of each image stream based on the specific resolution requirements without requiring static pre-allocation of large memory buffers. This dynamic approach enables high system flexibility while minimizing memory requirements.
Solution Approach 2:
The asymmetric image splitter changes processing parameters (such as image dimensions, resolution, and format) on-the-fly for different image streams. By dynamically adjusting these parameters rather than maintaining fixed memory allocations for all possible resolutions, the system achieves high adaptability while keeping memory requirements low.
3Adaptability or versatility
If asymmetric image splitter uses algorithm-based image extraction, then design flexibility is improved, but manufacturing precision and coordination requirements increase
Solution Approach 1:
The patent implements self-service mechanisms where the serializer automatically performs image stream separation and the receiver automatically reconstructs images using the transmitted data structure. This self-service approach eliminates the need for complex vendor coordination and precise manufacturing tolerances, as the system autonomously handles image extraction and reconstruction based on the standardized asymmetric splitting algorithm.

AI summary
Described herein are systems and methods that provide for implement an asymmetric image splitter engine that may reduce the memory requirements. In one or more embodiments, a method may comprise receiving a multi-streaming video comprising super-frame video images, where each super-frame video images includes a first video image and a second video image, and where the height of the first video image is higher than the second video image. The vertical asymmetry of the second video image may be adjusted to same height as the first video image by adding padding to the second video image. An asymmetric image splitter engine may be utilized to split the super-frame video images into two separate video images. By marking each line of the second video image, it may be determined which lines are padded and discarded, and which lines are data to be displayed using a line mark memory.
