Processing Chip for 8K UHD Video Data Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems struggle to handle video data with resolutions higher than 4K, as main chips are unable to process encoded video streams with 8K ultra high definition (UHD) resolution, leading to inefficiencies in data processing and throughput.
Innovation Solution
A video processing system comprising a main chip and a processing chip, where the processing chip is capable of handling video data with resolutions up to 8K UHD by receiving and processing encoded video streams from the main chip, utilizing transmission interfaces like USB and HDMI, and performing operations such as video encoding/decoding, de-interlacing, and OSD graphic rendering to enhance processing capabilities.

Engineering Contradiction Analysis
1Measurement precision
If the resolution of video data is increased to achieve higher video quality, then video quality is improved, but processing requirements such as data rate and data throughput increase
Solution Approach 1:
The system divides video processing into two segments: the main chip handles lower resolution video data, while the processing chip handles higher resolution video data. This segmentation allows each chip to operate within its optimal performance range, enabling the system to process 8K UHD video without overwhelming a single processor's data throughput capacity.
2Device complexity
If existing main chips are used to process video data, then device complexity is kept simple, but the chips are unable to process video data with maximum resolution of 8K UHD
Solution Approach 1:
The processing chip acts as an intermediary between the main chip and the display device. It receives encoded video streams from the main chip, performs additional processing operations (de-interlacing, frame rate transformation, OSD graphic rendering), and outputs the final processed video signal. This intermediary approach enables 8K UHD processing without requiring the main chip to be redesigned.
3Ease of operation
If a single chip is used for video processing, then ease of operation is maintained, but processing capabilities are insufficient for high resolution video playback and display
Solution Approach 1:
The system merges the functional capabilities of two chips: the main chip provides basic video processing and encoding, while the processing chip adds advanced processing functions including de-interlacing, frame rate transformation, and OSD graphic rendering. Together, they deliver comprehensive processing capability for 8K UHD video while maintaining ease of operation through automated processing pipelines.

AI summary
A video processing system includes a main chip and a processing chip. The main chip receives first data. The processing chip is coupled to the main chip, and receives second data and to perform a video processing on at least one of the first data transmitted from the main chip and the second data, in order to drive a display panel. First video carried on the first data or second video on the second data has a first resolution, and the first resolution is at least 8K ultra high definition.
