Variable Scrolling Speed for Motion Picture Character Strings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion picture playing methods fail to harmonize the playback mode of motion pictures with the display mode of overlaid character strings, leading to discomfort for viewers due to constant scrolling speeds regardless of playback mode or display mode.
Innovation Solution
A method and apparatus that control the display mode of character strings based on their length and the playback time of motion pictures, ensuring synchronization and harmony between the two modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the character string is scrolled and displayed at a constant speed, then the display mode is simple and easy to implement, but the playing mode of the motion picture image and the display mode of the character string become greatly different, causing viewer discomfort
Solution Approach 1:
The patent applies dynamics by changing the scrolling speed of the character string from constant to variable. The scrolling speed is dynamically adjusted based on the playing mode of the motion picture image (e.g., normal play, fast forward, rewind) and the display mode parameters, allowing the display to adapt to different playback scenarios and maintain harmony between the two modes.
Solution Approach 2:
The patent changes the parameter of scrolling speed based on other parameters such as playing mode and display mode. By establishing a relationship where the scrolling speed varies according to the playing mode (e.g., faster scrolling for fast forward, slower for normal play) and display mode parameters, the system achieves coordinated behavior between motion picture playback and character string display.
2Adaptability or versatility
If the character string scrolling speed is adjusted to match playing mode, then the harmony between playing mode and display mode is improved, but the control complexity increases
Solution Approach 1:
The patent implements feedback by continuously monitoring the playing mode of the motion picture image and using this information to adjust the character string scrolling speed. The system receives feedback about the current playback state (normal play, fast forward, rewind, pause) and automatically adjusts the display parameters accordingly, creating a closed-loop control system that maintains coordination between playback and display.
Solution Approach 2:
The patent makes the display control system multi-functional by enabling it to handle multiple playing modes through a single unified control mechanism. The same control unit that manages the motion picture playback also controls the character string display, allowing one system to serve multiple functions (playback control, display control, speed coordination) without requiring separate independent control systems.

AI summary
A motion picture playing method for playing a motion picture image on a display unit includes a motion picture image-obtaining step for obtaining the motion picture image, a character string-obtaining step for obtaining a character string scrolled and displayed in a predetermined direction overlaid on the motion picture image obtained in the motion picture image-obtaining step, and a control step for controlling a display mode for scrolling and displaying the character string based on (i) a length of the character string in the predetermined direction obtained in the character string-obtaining step, and (ii) a playing time of the motion picture image obtained in the motion picture image-obtaining step.
