Playback Apparatus Message Control via Recording Medium Program
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional content playback systems lack the ability for content providers to control messages displayed to users, as these messages are determined by the manufacturer rather than the content provider, limiting the provider's authority over informing users of playback anomalies or unauthorized usage.
Innovation Solution
A recording medium and playback apparatus system where the content provider records a program that interacts with the playback apparatus to transmit messages based on apparatus unique information or state, allowing the provider to control the messages displayed, including notifications for unauthorized or anomalous conditions and the option to inhibit playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the manufacturer of the playback apparatus decides messages for informing users of anomalies, then the playback apparatus can display messages to users, but the content provider cannot control the messages
Solution Approach 1:
The patent introduces a program recorded on the recording medium as an intermediary that bridges the content provider and the playback apparatus. This program receives apparatus information from the playback apparatus, determines appropriate messages, and transmits them back to the playback apparatus for display. This intermediary mechanism enables content provider control over messages without requiring direct integration into the playback apparatus hardware, thus resolving the contradiction between ease of message control and system complexity.
Solution Approach 2:
The patent implements a feedback loop where the playback apparatus provides apparatus information (such as unique identification or state data) to the program on the recording medium, which then determines and sends back appropriate messages. This feedback mechanism allows the content provider to control messages based on actual playback conditions while maintaining a relatively simple system architecture through automated information exchange.
2Reliability
If the content provider wants to control messages displayed to users, then the provider can influence user perception and compliance, but the system requires interaction between the recording medium program and playback apparatus
Solution Approach 1:
The program recorded on the recording medium autonomously performs the functions of receiving apparatus information, determining appropriate messages, and transmitting them to the playback apparatus. This self-service capability allows the content provider to maintain reliable copyright protection through automated message control without requiring complex manual intervention or sophisticated interaction mechanisms, thus improving reliability while keeping the interaction mechanism simple.
3Adaptability or versatility
If the playback apparatus displays messages based on apparatus unique information, then the content provider can control messages according to apparatus characteristics, but the system must acquire and process additional information
Solution Approach 1:
The patent utilizes apparatus unique information (such as device identification parameters) as input to the program on the recording medium. The program processes these parameter changes and determines customized messages accordingly, then transmits them to the playback apparatus. This approach enables message customization based on apparatus characteristics while maintaining a simple information processing structure, as the program handles the parameter processing rather than requiring complex built-in processing capabilities in the playback apparatus.

AI summary
A recording medium, which is provided by a content provider and allows the content provider to control messages, has recorded thereon content and a program executed at a time of playback of the content by a playback apparatus. The program causing the playback apparatus to interact with a different program prestored in the playback apparatus and executed at the time of the playback of the content and to transmit, to the different program, a message determined according to the result of the interaction. The playback apparatus includes a reading unit reading the program from the recording medium at the time of the playback of the content, a startup unit starting up the read program, an interaction unit interacting with the program, and a processing unit receiving a message corresponding to a result of the interaction from the recording medium and performing a process corresponding to the received message.
