Lossless Compression for 4K Multimedia Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide visually lossless high-resolution 4K/60 fps multimedia transmission due to bandwidth limitations, often resulting in data loss and reduced image quality, especially in low-bandwidth connections like Thunderbolt, which can only achieve 55-58 fps, falling short of user expectations.
Innovation Solution
A method involving a multimedia processing device with a super-resolution receiver, lossless compressor, PCI-E converter, and interface connector that processes and decompresses super-resolution image data to maintain 4K/60 fps specifications through lossless compression and decompression, ensuring the resolution and quality of the displayed image are preserved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If image data is compressed to reduce bandwidth requirements, then low-bandwidth display links can provide digital video on high-resolution displays, but the compression is not visually lossless and may result in data loss
Solution Approach 1:
The patent changes the compression parameter from conventional lossy compression to lossless compression, maintaining data integrity while reducing bandwidth requirements. The lossless compression algorithm achieves approximately 50% compression ratio while preserving all original image data, eliminating visual artifacts and data loss associated with traditional compression methods.
2Quantity of substance
If conventional compression methods are used to achieve 4K resolution, then bandwidth requirements are reduced, but the frame rate drops to 55-58 fps instead of maintaining 60 fps
Solution Approach 1:
The patent changes the compression approach to lossless compression, which provides sufficient compression ratio (approximately 50%) to meet bandwidth requirements while preserving all original data. This enables the system to maintain the full 60 fps frame rate at 4K resolution without the data loss or frame rate reduction associated with conventional lossy compression methods.
3Measurement precision
If high-resolution display is implemented, then image quality is improved, but the bandwidth requirement increases proportionally
Solution Approach 1:
The patent applies lossless compression to change the data transmission parameter, reducing the bandwidth requirement by approximately 50% while maintaining the full 4K high-resolution display quality. The compression occurs during transmission, and the original high-resolution data is recovered at the receiving end, preserving both resolution and bandwidth efficiency.
Data Source
AI summary
A method is provided for lossless transmission. Super-resolution image data are processed. The image data are transferred in a super-resolution mode to a super-resolution receiver. After being received, the image data are sequentially transferred to a lossless compressor and a PCI-E converter for lossless compression and PCI-E conversion. Thus, compressed image data are generated. Through an interface connector, the compressed image data are transferred in the same mode with the same specifications to a receiving terminal. After being received, the compressed image data are transferred to a driver to be decompressed and displayed on a display. Consequently, a data-collecting device can be fabricated. Therein, after original image data are processed through lossless compression, original image quality can be restored through decompression; the lossless image data are outputted and displayed at the receiving terminal; and the resolution and quality of displayed image are manifested with the original specifications.
