Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices face limitations in providing an optimal viewing environment for HD images due to fixed transmission speeds, leading to visual discomfort from sudden changes in image features like brightness, which hampers the delivery of a realistic and immersive experience.
Innovation Solution
An electronic device that receives and stores HD video frames at a variable transmission speed, adjusts features of frames to minimize differences between consecutive frames, and allows user input for picture quality adjustments, using a processor to control the display and communication interface to enhance the viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HD video signals are transmitted at a fixed transmission speed, then the TV can receive and display the signals at a predetermined playback speed, but the TV is limited in providing better viewing environment because it cannot adapt to feature changes in HD images
Solution Approach 1:
The patent applies dynamics by changing the transmission speed from fixed to variable. The processor dynamically adjusts the transmission speed based on the vertical frequency of the video signal and detected image features, allowing the system to adapt to different playback scenarios and maintain optimal viewing quality across varying conditions
Solution Approach 2:
The patent changes the parameter of transmission speed from a fixed value to a variable parameter that can be adjusted according to vertical frequency and image feature changes. This allows the system to optimize the balance between receiving high-speed signals and maintaining stable playback, resolving the contradiction between adaptability and complexity
2Manufacturing precision
If the transmission speed of HD video signal is increased to improve picture quality, then the TV can receive more frames per second, but sudden changes in image features like brightness cause visual discomfort to users
Solution Approach 1:
The patent applies preliminary action by detecting image features in advance and preparing adjustment strategies before abrupt changes occur. The processor analyzes vertical frequency and image features proactively, allowing it to preemptively adjust transmission speed or apply smoothing algorithms to prevent visual discomfort from sudden brightness changes
Solution Approach 2:
The patent implements feedback by continuously monitoring image features during playback and adjusting transmission speed or display parameters based on detected changes. This closed-loop system identifies when feature changes occur and responds by modulating transmission speed or applying transition smoothing to maintain picture quality while preventing visual discomfort
3Ease of operation
If the TV plays back HD images at a fixed playback speed, then the system is simple to operate, but the viewing environment quality deteriorates when image features change drastically
Solution Approach 1:
The patent applies self-service by enabling the system to automatically detect and respond to image feature changes without user intervention. The processor autonomously monitors vertical frequency and image characteristics, dynamically adjusting transmission speed and playback parameters to maintain optimal viewing quality, thus preserving simplicity for the user while improving reliability of the viewing environment
