Mobile Video Device Man-Machine Operation Picture Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video communication systems for mobile devices lack the ability to transmit man-machine operation pictures effectively, leading to misunderstandings and incorrect data recording due to unclear voices or oral mistakes, especially when users of different devices with similar functions need to communicate.
Innovation Solution
A method and system for transmitting man-machine operation pictures between mobile video devices, where a first mobile video device converts display picture data from its video buffer into video data compliant with a specific format and transmits it to a second device using a video communication protocol, allowing precise display of operation pictures on the receiving device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users communicate through oral statements only, then the communication process is simple, but misunderstandings and incorrect data recording occur due to unclear voices or oral mistakes
Solution Approach 1:
The patent captures the actual display content from the first mobile video device's screen and transmits it as visual copy to the second device. This copying approach eliminates oral communication errors by directly replicating the visual information, thereby improving communication reliability without significantly increasing system complexity since the display buffer data is already available.
2Productivity
If users teach function module usage orally, then the teaching process is simple, but the learning efficiency is low as the learner can only understand through oral statements
Solution Approach 1:
The patent enables real-time transmission of display content showing function module operations from the instructor's device to the learner's device. This visual copying allows the learner to directly observe the operation steps on their own device screen, dramatically improving learning efficiency while maintaining ease of operation since both parties use identical device interfaces.
3Reliability
If display picture data is transmitted directly without conversion, then the transmission process is simple, but the video data may not comply with standard video formats
Solution Approach 1:
The patent converts display picture data from the device's native format into standard video formats (such as H.263, H.264, or MPEG-4) before transmission. This parameter transformation ensures broad compatibility with various video communication systems and protocols, improving reliability. The conversion process, while adding some processing complexity, leverages existing codec libraries and maintains reasonable computational requirements.

AI summary
A method for transmitting a man-machine operation picture, a mobile video device thereof, and a video system using the same are provided, which are applicable to a first mobile video device and a second mobile video device wirelessly connected to each other, and the first mobile video device includes a first screen. A display picture data is obtained from a video buffer of the first screen. The first screen displays a first picture according to the display picture data. The first mobile video device converts the display picture data into a video data compliant to a video format, and transfers the video data to the second mobile video device according to a video communication protocol. The second mobile video device displays a second picture according to the received video data, and a displaying content of the second picture substantially includes a displaying content of the first picture.
