Electronic Gaming Machine Video Signal Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic gaming machines lack the ability to record, store, and replay video output of games played on them, preventing real-time remote viewing and leading to potential discrepancies between stored outcome data and actual game visuals.
Innovation Solution
An electronic gaming machine equipped with a computer, programmable processor, and storage unit that records and stores video output in real-time as a file, allowing for replay on the machine or remote devices, and enables transmission of this video file for indefinite retention and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional text format storage or re-creation methods are used, then device complexity is reduced, but measurement precision and reliability of game outcome records deteriorate
Solution Approach 1:
The patent applies the copying principle by capturing and storing a visual copy (video signal) of the game outcome display rather than relying on text summaries or re-creation. The video recording system captures the actual visual output shown to the player, creating an accurate duplicate record that can be stored and reviewed later, ensuring the record matches exactly what was displayed during gameplay.
Solution Approach 2:
The system performs preliminary action by capturing and storing the video signal immediately during or right after the game outcome is displayed, before any potential discrepancies can occur. This real-time or near-real-time recording ensures the visual record is preserved in its original state, eliminating the need for later re-creation and preventing divergence between stored data and actual display.
2Reliability
If real-time video recording is implemented, then reliability and measurement precision improve, but loss of time and storage requirements increase
Solution Approach 1:
The system implements continuous action by capturing the video signal continuously during the game outcome display period without interruption. The recording process runs continuously for the duration needed to capture the relevant game information, ensuring no critical moments are missed and the record is complete and reliable.
Solution Approach 2:
The system applies skipping by capturing only the essential time window needed to record the game outcome - specifically the period when the result is displayed. Rather than recording indefinitely, the system rushes through the critical capture phase efficiently, recording only long enough to preserve the outcome information, then stopping to minimize storage and processing time.
3Loss of information
If video output is recorded and stored, then information completeness improves, but device complexity and storage requirements worsen
Solution Approach 1:
The system creates a complete information copy by recording the video signal that contains all visual information displayed during the game outcome. This video copy preserves every visual detail shown to the player, including graphics, text, and animations, providing complete information without requiring separate storage of multiple data types.
Solution Approach 2:
The video recording system serves multiple functions simultaneously: it captures the game outcome for record-keeping, provides evidence for dispute resolution, enables replay for player review, and creates an archive for auditing. This multi-functionality reduces the need for separate systems for each purpose, managing complexity through consolidation.
