Solution Overview

Problem

In video delivery systems, users cannot ascertain which of multiple output videos from an electronic device is the PGM output video when the device outputs videos corresponding to multiple regions.

Innovation Solution

An electronic device with an acquisition unit, output unit, and control unit that identifies and displays which region a received tally signal corresponds to, using OSD tallies or frame modifications to distinguish PGM and NEXT output videos.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If an electronic device outputs multiple videos corresponding to multiple regions, then the device can simultaneously output multiple videos using a single device, but the user cannot ascertain which video is the PGM output video

Engineering Contradiction:
Improvenumber of videos outputVSAvoididentification information of output video
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent applies color changes by displaying tally indicators in different colors (red for PGM, green for NEXT) within the video image to distinguish between different output video states. This allows users to visually identify which region corresponds to the PGM output video among multiple output videos.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent adds a new dimension of information display by superimposing tally indicators on the video image itself, rather than using separate external indicators. This integrates the identification information into the video display, allowing users to ascertain the PGM output video status directly from the video image.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If a tally lamp is used to indicate PGM output video, then the user can ascertain the output video status, but the user cannot identify which specific region corresponds to the PGM video when multiple regions are output

Engineering Contradiction:
Improvevideo output status indicationVSAvoidvideo region identification
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the tally indication function with the video display by superimposing tally indicators directly on the video image. This combines the status indication and region identification into a single integrated display, allowing users to simultaneously see both the video content and the PGM/NEXT status for each region.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces tally indicators as intermediary elements that are displayed within the video image to mediate between the multiple video regions and the user's need to identify which region is outputting PGM video. These indicators serve as visual mediators that link the region information with the output status.

Inventive Principle:
Principle #24Intermediary (Mediator)
