Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional data broadcasting receiving function is utilized, then basic content reception is achieved, but high-value added functions and high resolution video capabilities are not provided
Solution Approach 1:
The patent implements dynamic output control where the control unit adjusts the output state of contents based on real-time evaluation of multiple factors including copy control information, protection necessity, video resolution, and transmission characteristics. This dynamic adaptation allows the system to provide high-value added functions while maintaining content protection reliability by flexibly modifying output behavior according to specific conditions.
Solution Approach 2:
The control unit changes output parameters (such as output enable/disable state, resolution, and transmission characteristics) based on received control information. By dynamically adjusting these parameters according to copy control states and protection requirements, the system achieves both enhanced functionality and maintained content security.
2Ease of operation
If output control is simplified, then ease of operation is improved, but content protection and quality control are compromised
Solution Approach 1:
The control unit autonomously determines the output state by automatically evaluating control information, protection requirements, video resolution, and transmission characteristics without requiring manual intervention. This self-service mechanism simplifies operation for users while ensuring content protection and quality control are maintained through automated decision-making based on predefined criteria.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit continuously monitors control information and adjustment results, using this feedback to refine output state determination. This ensures that content protection and quality requirements are met while maintaining operational simplicity through automated closed-loop control.

AI summary
A digital broadcast receiving apparatus capable of executing a function with a higher added value is provided. A broadcast receiving apparatus configured to receive contents includes: a receiving unit configured to receive the contents; an interface via which the contents received by the receiving unit is outputted; a control unit configured to control an output state of the contents from the interface. In this case, the control unit is configured to determine the output state of the contents from the interface in accordance with a combination of control information indicating a copy control state of the contents, control information for specifying necessity or not of protection when to output the contents, information indicating resolution of video of the contents, and information indicating transmission characteristics of video of the contents, which are received by the receiving unit together with the contents.
