Repeat Key Input Across VCDs Despite OCR Recognition Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems face issues where optical character recognition (OCR) processing failures lead to inconsistent key entries when switching between different video coding desks (VCDs), as the repeat key inputs may not match the previous entries made on different VCDs.
Innovation Solution
An information processing apparatus and system that includes an OCR device to perform secondary OCR on VCD screens, displaying them if necessary, and using emulators to input operation signals based on repeat or shortcut keys to ensure consistent entry across VCDs, even in the event of OCR failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If OCR processing is used to automatically recognize character strings on VCD screens, then input efficiency is improved, but when OCR fails the system cannot reliably input the correct previous entry when switching between different VCDs
Solution Approach 1:
The patent introduces an intermediary mechanism (repeat key function with VCD identification) that mediates between the OCR system and the manual input system. When switching between VCDs, the system identifies the current VCD and retrieves the corresponding previous entry through this intermediary mechanism, ensuring reliable entry consistency while maintaining the efficiency benefits of OCR for standard operations.
2Speed
If the system stores and retrieves previous entries for repeat key functionality, then input speed is improved, but system complexity increases due to the need to manage and match entries across multiple VCDs
Solution Approach 1:
The patent applies preliminary action by pre-storing previous entries in association with specific VCD identifiers before the repeat key is pressed. When a VCD switch occurs, the system has already prepared the corresponding previous entry data, eliminating the need for complex real-time matching and retrieval logic, thus maintaining low system complexity while achieving fast input speed.
3Measurement precision
If manual entry is required when OCR fails, then accuracy can be maintained, but time consumption increases and operator workload increases
Solution Approach 1:
The patent implements partial action by providing the operator with a pre-filled repeat entry that contains the previous VCD's data. The operator only needs to verify or make minor corrections rather than entering the complete information manually. This partial manual intervention maintains input accuracy while significantly reducing time consumption compared to full manual entry.

AI summary
According to an embodiment, an information processing apparatus includes an image interface, an input interface, a display interface, a manipulation interface, a storage unit, and a processor. The processor is configured to cause a display terminal through a display interface to display a screen so as to receive an input of a key through the manipulation interface; transmit an operation signal indicating the key to the one of external devices through the input interface; and when the key is a repeat key, transmit an operation signal for inputting a character string indicated by repeat information to the one of the external devices through the input interface.
