Electronic Device With Tally-Linked OSD for PGM Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video delivery systems, when an electronic device outputs multiple videos corresponding to multiple regions, users cannot ascertain which video is the PGM output video.
Innovation Solution
An electronic device equipped with a processor and memory that executes processes to identify and display cropped regions within a video, using tally signals to distinguish between PGM and NEXT output videos through on-screen display (OSD) overlays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic device outputs multiple videos corresponding to multiple regions, then the device versatility and functionality are improved, but the user cannot ascertain which video is the PGM output video
Solution Approach 1:
The patent applies color changes by displaying the tally signal (PGM/NEXT status) in a specific color (red for PGM, green for NEXT) within the cropped region. This allows users to visually distinguish which video corresponds to which output status through color coding, resolving the information loss problem while maintaining multi-region output functionality
Solution Approach 2:
The patent introduces an intermediary element (the cropped region display with tally signal overlay) that mediates between the multiple video outputs and the user. This intermediary display layer provides status information without interfering with the actual video output functionality, allowing both versatility and information clarity to coexist
2Loss of information
If a tally lamp is used to indicate PGM output status, then the user can ascertain video output status, but the user cannot identify which of multiple videos is the PGM output
Solution Approach 1:
The patent segments the display into multiple cropped regions, each corresponding to a specific video output region. The tally signal is displayed within the specific cropped region that corresponds to the PGM output video. This segmentation allows users to visually match the tally indicator with the correct video region, solving the identification problem
Solution Approach 2:
The patent applies local quality by displaying different information (tally signal) in specific local regions (cropped regions) of the video display. Each cropped region has unique visual characteristics that correspond to its function, allowing users to easily identify which video is the PGM output based on the local display characteristics
