Video Display System Portable Data Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video display devices can only output video and sound data for display and reproduction on their own or connected monitors and speakers, limiting the means by which users can access the content.
Innovation Solution
A video display system comprising a video display device and a portable video display device connected for communication, where the system includes means to produce, encode, and send video and sound data in formats compatible with the portable device, allowing display and reproduction on various devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video display device outputs data only in its native format, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The video display device performs data conversion in advance by encoding video and sound data into formats compatible with portable devices before transmission. This preliminary encoding action ensures that the portable device can directly play back the received data without requiring complex real-time conversion, thus resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If video and sound data are converted to multiple formats, then adaptability improves, but processing time increases
Solution Approach 1:
The system performs encoding of video and sound data into portable device-compatible formats before transmission occurs. By completing the conversion in advance rather than during playback, the system achieves multi-device adaptability without causing time loss during actual use, as the portable device can immediately play back the pre-encoded data.
3Adaptability or versatility
If data is transmitted to portable device, then versatility improves, but system complexity increases
Solution Approach 1:
The video display device incorporates multiple functions including native format output, encoded format generation, and data transmission capabilities within a single integrated system. This multi-functionality allows the device to serve both traditional display purposes and portable device compatibility without requiring separate dedicated systems, thus improving versatility while managing system complexity.

AI summary
To provide a video display system for allowing a user to look at and listen to video and sound on various means. A video display system has a video display device and a portable video display device, connected to each other for communication. The video display device produces own device video data and own device sound data to be displayed and reproduced, respectively, on the video display device; displays the own device video data and reproduces the own device sound data; encodes these data into a data format which the portable video display device is able to handle, to thereby produce other device video data and other device sound data; and sends to the portable video display device. The portable video display device receives these data, and decodes and displays the other device video data, and decodes and reproduces the other device sound data.
