Dual-Stream Image Encoding for Storage and Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in recording and transmitting high-quality image data in real-time without relying on network environments, often compromising on image quality due to poor network conditions.
Innovation Solution
An electronic device with a camera, encoder, communication circuit, and processor that encodes image data in two different manners: one for recording (high-quality) and another for transmission (lower quality), allowing for real-time transmission even in poor network conditions by adjusting encoding parameters based on network quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image data is encoded with high quality for recording, then recording quality is improved, but transmission efficiency deteriorates due to larger data size
Solution Approach 1:
The patent divides the encoded data into two separate streams: first encoded data optimized for recording with high quality parameters, and second encoded data optimized for transmission with compressed parameters. This segmentation allows each stream to be independently optimized for its specific purpose without compromise.
Solution Approach 2:
The patent applies different encoding qualities to different destinations: high-quality encoding for local recording and lower-quality encoding for remote transmission. This local quality differentiation ensures that recording maintains maximum quality while transmission adapts to network constraints.
2Productivity
If image data is compressed for transmission in poor network conditions, then transmission efficiency is improved, but recording quality deteriorates
Solution Approach 1:
The encoding system segments the output into two distinct data streams with different compression levels. The first stream uses high-bitrate encoding for recording, while the second stream uses adaptive bitrate encoding for transmission, allowing quality preservation in recording regardless of network conditions.
Solution Approach 2:
The patent dynamically changes encoding parameters based on the destination and network conditions. For recording, parameters are set to maximum quality; for transmission, parameters are adjusted in real-time based on network bandwidth availability, ensuring efficient adaptation without compromising recording quality.
3Reliability
If dual encoding is performed simultaneously, then both recording and transmission quality are maintained, but device complexity increases
Solution Approach 1:
The patent combines multiple encoding functions into a unified encoder module that can generate both first encoded data and second encoded data from the same input image data. This merging approach reduces overall system complexity compared to using separate encoding systems, while still maintaining the ability to produce differentiated output streams.
Data Source
AI summary
Methods and devices for image data encoding are provided. Image data is created using at least one image captured by a camera of the electronic device. First encoded image data is created by encoding at least a portion of the image data in a first manner. Second encoded image data is created by encoding the at least a portion of the image data in a second manner. The second manner is different from the first manner. The first encoded data is stored in a memory of the electronic device. The second encoded data is transmitted from the electronic device to an external device.
