Multimedia Replay System Using Timestamp Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users need to manually adjust the playback of multimedia data to replay specific segments, lacking an efficient method to control and manage playback.
Innovation Solution
A replaying system and method that utilizes a processor to control a playing device to replay multimedia data from a specified time stamp to another, allowing users to initiate and terminate playback with specific instructions, such as pressing a keyboard spacebar twice to return to a previous time stamp and resume playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually adjust playback to replay specific segments, then playback control is achieved, but operation complexity and time consumption increase
Solution Approach 1:
The system performs preliminary actions by automatically detecting key moments and pre-processing the multimedia content to identify replay segments. When a user triggers a replay function, the system has already prepared the necessary information about where and how to replay, eliminating the need for manual adjustment and reducing time consumption.
Solution Approach 2:
The replay system serves itself by automatically identifying replay segments and managing playback control without requiring user intervention. The system autonomously detects key moments, determines replay parameters, and executes the replay, making the playback control process self-service and highly efficient.
2Extent of automation
If automated replay control is implemented, then user experience is enhanced, but device complexity increases
Solution Approach 1:
The processor is designed with multi-functionality, serving both as the detection engine for identifying key moments and as the control unit for managing replay playback. This universal component approach reduces overall system complexity while achieving high automation, as one versatile processor handles multiple functions that would otherwise require separate dedicated components.
Data Source
AI summary
A replaying system includes a playing device and a processor. The playing device is configured to play multimedia data. The processor is coupled to the playing device. The processor is configured to control the playing device to replay data from a second time stamp to a first time stamp of the multimedia data according to a first instruction corresponding to the first time stamp. The processor is further configured to release the data from being replayed according to a second instruction.
