Content Transmission Device Network Location Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with mobile devices, such as notebook PCs or portable terminals, face limitations in accessing copyrighted content from outside their household or residential network, as existing systems require confirmation that the transmission and reception devices are within the same household for copyright protection purposes.
Innovation Solution
A content transmission device that includes a reception unit, communication processing unit, connection determination unit, and control unit, which determines if the connected device is on an intra-residential network; if not, it restricts output to prevent unauthorized access, allowing users to access intra-residential content from outside the residence while maintaining copyright protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system requires confirmation that transmission and reception devices are within the same household for copyright protection, then copyright protection is ensured, but users cannot access content from outside the residence
Solution Approach 1:
The patent segments the network environment into two distinct types: intra-residential network and extra-residential network. The connection determination unit identifies which network type the receiving device is connected to, allowing the system to apply different content transmission rules for each segment. This segmentation resolves the contradiction by enabling content access outside the residence (improving ease of operation) while maintaining strict copyright protection within the residence (preserving reliability).
Solution Approach 2:
The patent applies different quality characteristics to different parts of the system based on network location. For intra-residential connections, the system allows content transmission with standard copyright protection. For extra-residential connections, the system prohibits transmission of copyrighted content. This local differentiation resolves the contradiction by tailoring the protection level to the specific network context, enabling mobile access where appropriate while maintaining security where needed.
2Ease of operation
If the system allows content transmission via network without location confirmation, then user convenience is improved, but copyright protection may be compromised
Solution Approach 1:
The connection determination unit performs preliminary action by determining the network connection status of the receiving device before the content transmission actually occurs. This advance identification allows the transmission control unit to make informed decisions about whether to permit transmission, resolving the contradiction by establishing protection measures in advance (maintaining reliability) while still allowing convenient access when conditions permit (preserving ease of operation).
Solution Approach 2:
The system implements feedback through the connection determination unit, which continuously monitors and identifies the network type of the receiving device. This feedback information is then used by the transmission control unit to adjust content transmission decisions dynamically. The feedback mechanism resolves the contradiction by enabling the system to respond appropriately to different network contexts, allowing access when safe and blocking when necessary.
3Reliability
If the system restricts content output when the device is not on intra-residential network, then copyright protection is maintained, but user convenience for mobile access is reduced
Solution Approach 1:
The patent introduces dynamics by making the content transmission capability dependent on the real-time network connection status of the receiving device. The transmission control unit dynamically adjusts whether content can be transmitted based on whether the device is connected to an intra-residential or extra-residential network. This dynamic approach resolves the contradiction by adapting the system behavior to the current usage context, maintaining protection when needed while enabling mobile access when appropriate.
Solution Approach 2:
The patent changes the parameter of network connection type (intra-residential vs. extra-residential) as the basis for controlling content transmission. The connection determination unit identifies this parameter, and the transmission control unit uses it to switch between different transmission permission states. This parameter-based control resolves the contradiction by providing a clear, objective criterion for when to allow or restrict access, balancing protection and mobility.

AI summary
A content transmission device for transmitting a digital content to other device connected via a network, including a receiving unit that receives the digital content accompanied with a piece of copy control information indicating a condition of restricting the digital content from being copied, a communication processing unit that transmits and receives the digital content or control commands to and from the other device, a connection determining unit that determines whether the other device is present on an intra-residential network connected by the content transmission device, and a control unit that controls the receiving unit, the communication processing unit, and the connection determining unit, in which the control unit does not output the digital content received by the receiving unit from the communication processing unit to the other device in a case where the other device is determined not to be installed at an inside of a residence.
